# Configuration Reference
For installation and the reading order, start at [Quick Start](../../README.md#quick-start). This page describes the core TOML fields. Unknown framework keys are rejected; relative paths resolve from the TOML file's directory. `environment.settings` is validated by its adapter.
Templates: [Textual Policy Learning](memory.template.toml), [UCB-based Policy Learning](ucb.template.toml), and a runnable [synthetic example](synthetic.example.toml). The Textual and UCB templates require an adapter and replacement of every `REPLACE_ME` value.
## Policy
Both methods learn the policy for improving agents while keeping language-model weights fixed. UCB-based Policy Learning updates outcome statistics and uses KL-UCB to balance exploration and exploitation. Textual Policy Learning updates reusable lessons stored in Policy Memory.
| Table / field | Purpose |
| --- | --- |
| `policy.method` | Select `"memory"` for Textual Policy Learning or `"ucb"` for UCB-based Policy Learning. |
| `policy.direction_slate_size` | Number of directions in a proposed slate. |
| `policy.max_planning_attempts` | Maximum whole-slate replacements per logical round. |
| `policy.proposer` | Model and investigation limits for proposing changes. |
| `policy.memory.ranker` | Model that ranks directions using Policy Memory; Textual selects the first ranked item. |
| `policy.memory.summarizer` | Model that distills and revises Policy Memory from completed execution and evaluation feedback. |
| `policy.memory.max_chars` | Maximum Policy Memory size. |
| `policy.semantic` | UCB embedding model, calibration identity, and matching thresholds. |
| `policy.cooldown`, `policy.effectiveness`, `policy.neighborhood` | UCB retry, improvement, and exploration rules. |
In the core batch runner, Textual uses one frozen Policy Memory snapshot throughout a batch. After the batch's actions settle, `MemorySummarizer` combines the previous lessons with proposals, code changes, and evaluation outcomes into a validated summary; `SingleFileMemoryCarrier` saves it to the run's `memory.md`. The updated lessons guide the next batch's parent, direction-allocation, and proposal-selection decisions.
The asynchronous Arena research workflow reuses `MemorySummarizer` as build results and their B comparisons settle. It saves revised lessons in the `research-policy/memory` checkpoint for subsequent decisions, without waiting for a whole search batch to finish.
Each completion profile explicitly sets `provider`, `model`, `max_output_tokens`, `temperature`, and `disable_reasoning`; profiles do not inherit one another's values. Provider names must match the adapter's `ProviderRegistry`. For UCB, use the policy tables in the [UCB template](ucb.template.toml); embedding dimensions, identities, and thresholds must match an accepted calibration bundle. Keep your existing environment and worker settings when replacing the policy tables, and finish this configuration before collecting baseline evidence.
For Arena research, edit each policy profile's `model` field separately. The task solver uses `environment.settings.action_runtime.program.model_name`, in the form `openrouter/vendor/model-id`. The coding worker uses its [own model configuration](../integrations/arena/docs/workers.md).
For proposer investigation, `max_proposer_turns` bounds turns; `max_trace_reads` and `max_repository_reads` bound reads; optional `max_read_calls` adds a shared read limit. `max_read_bytes` bounds returned evidence and `max_context_bytes` bounds serialized request history, not the model's token window. See the [research reference](../integrations/arena/docs/research.md) for tool behavior.
## Runtime
| Field under `runtime` | Purpose |
| --- | --- |
| `database_path` | SQLite database for durable run records. |
| `runs_root` | Candidate workspaces and generated artifacts. |
| `worker_slots` | Maximum concurrent actions. |
| `sqlite_timeout_seconds` | SQLite lock timeout. |
| `lease_ttl_seconds` | How long an action ownership claim remains valid. |
| `lease_renew_interval_seconds` | Claim renewal interval; must be shorter than the TTL. |
| `require_provider_reported_cost` | Require authoritative provider cost data; missing data cannot be treated as zero. |
Create the configured output directories before running, and keep them under an ignored directory such as `runs/`.
## Environment Adapter
| Field under `environment` | Purpose |
| --- | --- |
| `factory` | Import path, for example `my_adapter:create_dependencies`. Called with `AppConfig`; returns `AssemblyDependencies`. |
| `identity` | Stable name for the task environment. |
| `settings` | Adapter-specific program, task, worker, and evaluation configuration. |
`AssemblyDependencies` supplies a provider registry and a per-batch environment factory, plus optional UCB calibration. The environment connects durable search inputs, an action runner, a frozen evaluation plan, and an effectiveness rule. See the [core environment interface reference](../docs/environment-adapters.md) for implementation contracts and [worker configuration](../integrations/arena/docs/workers.md) for Arena research workers.
For benchmark-specific task splits and evaluation options, run `agentpilot-arena-aime-build --help` or `agentpilot-arena-tb2-build --help` through `uv run --project agentpilot/integrations/arena --no-sync` from the repository root. Both builders accept `--worker-config` and `--model`; role-specific model flags override `--model`.
## Campaigns and Resume
The optional `campaign` table is used by `agentpilot campaign`:
| Field | Purpose |
| --- | --- |
| `total_processes`, `actions_per_process` | Number of search processes and actions per process. |
| `max_planning_batches_per_process` | Bound on replacement planning batches. |
| `max_stalled_resumes` | Stop after this many consecutive resumes without durable progress. |
| `poll_interval_seconds` | Supervisor polling interval. |
| `reconciliation_deadline_seconds` | Maximum wait for provider accounting. |
Resume requires the original configuration and batch ID. AgentPilot rejects configuration or adapter changes that alter an active batch. In the batch runner, exhausted Policy Memory summarization attempts are a terminal policy-update failure rather than a resumable interruption.
## Credentials
Keep credentials in the environment or a local `.env` based on the repository [`.env.example`](../../.env.example); store only environment-variable names in adapter settings. `--env-file` loads the file for execution, with existing host variables taking precedence. `validate-config` checks framework TOML structure without loading credentials, importing the adapter, or contacting providers.

# Core Environment Interface Reference
This reference is for developers implementing AgentPilot's environment bindings. Adding a benchmark through these interfaces requires implementing the task source, action runner, evaluation plan and result integration. The existing runnable workflow and coding-worker setup are documented in the [AIME/Terminal-Bench setup guide](../integrations/arena/README.md).
If the initial program or evaluation is missing, the [preparation workflow](../integrations/arena/docs/preparation.md) can find reusable inputs and check an existing adapter. When no compatible adapter exists, implementing these bindings is a separate development task; preparation alone cannot launch the formal loop.
After cloning the repository through [Quick Start](../../README.md#quick-start), install the core from the repository root:
```bash
uv sync --project agentpilot --locked --python 3.12 --extra providers
```
For an offline smoke run, use the synthetic example (requires Git). Its outcomes and costs are simulated:
```bash
mkdir -p agentpilot/runs
uv run --project agentpilot --no-sync agentpilot run --config agentpilot/configs/synthetic.example.toml --run-id example --batch-id example-1 --rounds 2
```
The `native` / `provider` worker options are currently wired into the Arena research workflow. A custom core adapter supplies its own action runner; setting those worker options alone does not create one.
## Adapter Interface
Set `environment.factory` to an importable callable such as `my_adapter:create_dependencies`. AgentPilot calls it with `AppConfig`; it returns `AssemblyDependencies` containing a `ProviderRegistry`, an environment factory, and an optional UCB semantic calibration bundle.
The environment factory receives `BatchAssemblyContext` for each batch and returns `Environment`:
| Required field | Responsibility |
| --- | --- |
| `search_inputs` | A `DurableSearchInputSource` exposing the program and recorded results. Seed the initial program and baseline through `CanonicalSearchReadModelWriter`. |
| `action_runner` | An `ActionRunnerBinding` that runs the worker and evaluation under the active execution lease. |
| `evaluation_plan_freezer` | Freeze the tasks and paired measurements before actions execute. |
| `effectiveness_rule` | Decide whether the measured change is effective. |
| `trace_store` | A run-bound `TraceStore` with persisted Visible-A trace captures and manifests for each selectable program. |
| `definition_reader` | Read definitions from the selected parent's immutable source snapshot. |
UCB also needs compatible embedding providers, calibration, neighborhood predicates, and an applicability builder. The [synthetic adapter](../src/agentpilot/examples/synthetic_adapter.py) shows the complete interface; it uses deterministic stand-ins for external workers and models. The exact types are in [bindings.py](../src/agentpilot/app/bindings.py).
## Run an Implemented Adapter
After implementing the adapter and making its package importable in the AgentPilot environment, copy the [Textual Policy Learning template](../configs/memory.template.toml) to `agentpilot/configs/my-agent.toml`. Replace every `REPLACE_ME` value, set your factory and model profiles, and supply any required credentials in `.env`. The [configuration reference](../configs/README.md) explains the fields.
From the repository root, using the template's default output paths:
```bash
mkdir -p agentpilot/runs
uv run --project agentpilot --no-sync agentpilot run --config agentpilot/configs/my-agent.toml --env-file .env --run-id my-run --batch-id batch-1 --rounds 2
```
Use fresh run and batch IDs for a new run. To continue an interrupted batch, keep its configuration and IDs; see [campaigns and resume](../configs/README.md#campaigns-and-resume).

# Use AgentPilot in your coding agent
Use `/agentpilot` (or your host’s spelling below) to prepare and run an RSI experiment. The current agent fills in missing task/eval inputs, then starts the existing Arena or core runner when its adapter and evaluation are ready. If a prerequisite is missing, it explains what is needed; it does not replace AgentPilot with its own editing loop.
## Install once
From the repository root:
```bash
python install.py --host codex
```
The installer creates a dedicated runtime in `~/.local/share/agentpilot/host-runtime`, installs the core package, checks it, and adds the `agentpilot` skill. With `uv` installed it selects Python 3.12; otherwise run the installer with Python 3.11+ and working `venv`/pip support. Runtime installation may download Python or build dependencies. It does not change model settings or credentials, install project dependencies, or start a model or benchmark run. Its output gives the exact Python launcher and skill path.
Use `--prefix /path/to/runtime` to choose a different runtime, and `--skill-dir /path/to/skills` to choose a host's skill root. Re-run the same command from an updated checkout to update. An update checks skill-file conflicts before replacing the runtime, preserves unrelated files, and refuses to overwrite a skill changed outside this installer. It never commits or pushes.
If you prefer uv's tool installation:
```bash
uv tool install --python 3.12 ./agentpilot
agentpilot setup --host codex
```
### Supported hosts
Use `python install.py --host NAME`. All hosts use the same skill; the installer selects the host's skill directory and invocation.
| Host | `NAME` | Default skill directory | Invocation |
| --- | --- | --- | --- |
| Codex | `codex` | `~/.agents/skills` | `$agentpilot` or `/skills`; optional desktop plugin below. |
| Claude Code | `claude-code` | `~/.claude/skills` | `/agentpilot` |
| OpenCode | `opencode` | `~/.config/opencode/skills` | CLI: `/agentpilot` (verified with 1.19.5); V2 also supports `@agentpilot`. |
| Cursor | `cursor` | `~/.cursor/skills` | `/agentpilot` |

| Grok Build | `grok` | `~/.grok/skills` | `/agentpilot` |

OpenCode, Hermes and DSH respect `XDG_CONFIG_HOME`, `HERMES_HOME` and `DSH_AGENTS_HOME`, respectively. nanobot reads its default config, falling back to workspace environment settings; use `--skill-dir` for a separate instance. For another compatible host, use `--host generic --skill-dir /its/documented/skills/path`.
The host needs skill support, local file editing, and command execution. Having a CLI alone does not establish those capabilities. WorkBuddy ZIPs contain an absolute runtime launcher: export on the machine where the skill will run. WorkBuddy and CodeBuddy are distinct products; no WorkBuddy CLI or slash spelling is assumed. Grok Build is the local coding agent, not Grok Bot. Muse here means Meta Muse Code. Restart the host or open a new chat if a new skill is not visible.
The directory integrations follow [AutoSwarm's host setup](https://github.com/HKUDS/AutoSwarm/blob/main/src/autoswarm/setup.py) and the host documentation linked in [the registry](../src/agentpilot/host/hosts.py). Installing a skill lets the host prepare inputs and operate AgentPilot. The formal worker separately needs an adapter for task input, execution options and results; merely having a CLI is insufficient.
<a id="codex-plugin"></a>
### Optional Codex plugin and @ entry
The repository also contains a local Codex plugin. With a Codex CLI that supports plugins, install the runtime, skill and plugin together:
```bash
python install.py --host codex --plugin
```
`--plugin` registers this checkout as a local marketplace and installs its AgentPilot plugin in Codex. The equivalent plugin-only commands are:
```bash
codex plugin marketplace add .
codex plugin add agentpilot@agentpilot-local
```
Alternatively open the repository in Codex and install AgentPilot from the `agentpilot-local` source in Plugins. Start a new chat and select the installed plugin with `@`. Its onboarding skill locates or installs the core runtime and loads the same coding workflow. This is a local plugin with local execution; it has not been published to the public plugin directory. Plugin availability and `@` selection depend on the client; `setup --host codex` alone installs a skill, not a plugin. See the [official plugin guide](https://developers.openai.com/plugins/build/plugins).
### Other components
```bash
python install.py --host claude-code --components agentpilot openspace rsi-arena
```
This adds `/agentpilot`, `/openspace`, and `/rsi-arena` in Claude Code (the names use `$` in Codex CLI). The last two are guided entrypoints to their existing setup flows: OpenSpace still needs its runtime and MCP connection, and Arena still needs the selected benchmark's dependencies, tasks, and model setup. They are installed only when requested and are not included in ordinary coding runs. Colon namespaces belong to a host's plugin system, not these skill names.
## Start in a project
```text
$agentpilot Help me improve this project's performance and make it run faster.
```
A bare invocation also works. The agent reads the project, infers a useful goal where possible and prepares suitable checks. It runs an initial measurement when an evaluator is available. For a performance task, this includes a representative workload and correctness checks. It asks only for essential information it cannot infer. Preparation uses the host's ordinary tools and needs no separate session or JSON plan.
The agent assesses readiness from the actual configuration and evaluation results. With a compatible adapter, working evaluation, model/worker access and budget, it continues into **proposer → worker → eval → policy feedback** through the existing runner. The runner owns candidate changes, run records and recovery. Ordinary project tests still need an environment adapter to enter this loop.
## Datasets and evaluation
**Already configured:** give the agent the runtime configuration or existing run directory. It follows the [Arena integration](../integrations/arena/README.md), [core environment](environment-adapters.md), or [Arena benchmark guide](../../arena/README.md) appropriate to that configuration. The formal UCB/Textual Policy Learning loop and its persisted state remain unchanged.
**Missing task or eval:** the current agent inspects the project, prepares the missing inputs and checks the actual evaluator. It can use the [existing preparation interfaces](../integrations/arena/docs/preparation.md) without dispatching another worker. It then launches the configured runner if ready; otherwise it reports the missing prerequisite. Automatic formal integration of arbitrary projects is not yet supported. The built-in Arena setup targets Harbor/Terminus 2 on AIME or Terminal-Bench; other projects need an implemented [environment adapter](environment-adapters.md).
**Custom eval:** give the command and success criterion, for example: `Use python evaluation/check.py; preserve output quality while reducing runtime.` The agent verifies that it measures the goal and detects relevant failures. Formal runs also require the corresponding task source, worker and environment adapter. A passing test command or static configuration check alone is insufficient.
**Model access:** the Arena research runner can reuse a configured worker CLI's model/login for proposer and Memory policy calls when their API credentials are absent. Use `--proposer-access worker --policy-access worker` to select this explicitly. Task evaluation and UCB embeddings retain their provider requirements; custom core adapters own their own provider assembly. CLI calls retain budget allowances with external billing, so login reuse does not make the entire loop free. See [worker access](../integrations/arena/docs/workers.md#reuse-the-worker-for-proposer-and-policy-calls).
**A/B/C datasets:** use the selected formal environment's protocol. A provides development evidence, B supplies validation feedback, and C is held out until final evaluation. Do not use C to guide subsequent improvement. Discovering project tests does not automatically create these splits.
## Inspect and resume
The installer returns an absolute launcher using its own Python. It accepts core commands such as `validate-config`, `run` and `resume`; use the environment where the selected adapter and provider dependencies are actually installed. Configuration validation alone does not prove that an evaluator runs.
An optional read-only helper suggests existing pytest, unittest, Node, Cargo and Go test commands:
```bash
agentpilot project inspect --cwd /path/to/project
```
It neither executes checks nor creates a session. The agent can also discover and run tests directly with the project's usual tools.
Continue preparation from the conversation and project artifacts. Resume experiments using their original runner and run identity. There is no separate host improvement loop. Re-running installation updates managed skills while protecting local edits.
The [installed skill](../src/agentpilot/host/skills/agentpilot/SKILL.md) contains the routing rules; [formal workflow details](../src/agentpilot/host/skills/agentpilot/references/formal.md) are loaded only when relevant. The agent chooses how to prepare incomplete inputs; the configured runner owns policy learning and evaluation. Commit restrictions still apply: a runner that creates candidate commits cannot be used under a blanket no-commit instruction.

# Set Up AgentPilot with Arena
Complete the [repository installation](../../../README.md#quick-start-harness), then follow these four steps from the repository root. This workflow requires Linux, Docker and bubblewrap (`bwrap`); it uses a coding worker to improve a Harbor agent on AIME or Terminal-Bench 2.1.
<a id="worker"></a>
## ① Connect your worker
```bash
mkdir -p runs/my-agent
```
Save your choice from [worker configuration](docs/workers.md) to `runs/my-agent/worker.toml`. The worker edits the program's code; it can use your harness's existing model/login or a provider such as OpenRouter.
<a id="program"></a>
## ② Prepare your program and tasks
If you do not have an initial program or evaluation yet, use the optional [preparation worker](docs/preparation.md). It finds or adapts the missing inputs and returns a structured handoff; other tasks use the custom environment route described there.
This workflow improves the Harbor/Terminus 2 program. Keep its editable checkout separate from the trusted evaluator:
```bash
git clone https://github.com/harbor-framework/harbor.git runs/my-agent/harbor
git -C runs/my-agent/harbor checkout --detach 7db020ba5a5ceee918351dd8fc374d4d60bad442
uv sync --project runs/my-agent/harbor --package harbor --no-dev --locked --python 3.12
git clone --no-hardlinks runs/my-agent/harbor runs/my-agent/program
```
For an existing Harbor program, skip the last command and use its path in `--program` below. Commit its changes before setup. Reuse an existing evaluator checkout by supplying its path in `--harbor`.
| Tasks | Preparation |
| --- | --- |
| AIME 2024+2025 | The 60 tasks and [task split](src/agentpilot_arena/aime/data/split.example.json) are included; step ③ builds the task image. |
| Terminal-Bench 2.1 | Complete [task and image preparation](docs/tb21.md), then continue to ③. |
<a id="policy"></a>
## ③ Choose your policy and model
Start with Textual Policy Learning (`policy.method = "memory"`), which learns reusable lessons in Policy Memory from evaluation feedback while keeping language-model weights fixed. Put `OPENROUTER_API_KEY` in the repository-root `.env`, then replace `vendor/model-id` with an OpenRouter model that supports tool use and structured responses. This model serves the proposer, direction ranker, memory summarizer, and task solver; your worker keeps the configuration from ①. Run the command for your benchmark.
The research command automatically reuses your worker's model/login for proposer, ranker, or summarizer roles whose API credential is absent. To use the worker for all three even with a shared API key available, add `--proposer-access worker --policy-access worker` to the research command in step ④. The task solver still uses its API configuration. See [worker login reuse](docs/workers.md#reuse-the-worker-for-proposer-and-policy-calls).
**AIME:**
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-arena-setup \
--benchmark aime \
--output runs/my-agent \
--program runs/my-agent/program \
--harbor runs/my-agent/harbor \
--worker-config runs/my-agent/worker.toml \
--model vendor/model-id \
--cell-max-cost-usd 2
```
**Terminal-Bench 2.1:**
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-arena-setup \
--benchmark tb21 \
--output runs/my-agent \
--program runs/my-agent/program \
--harbor runs/my-agent/harbor \
--worker-config runs/my-agent/worker.toml \
--model vendor/model-id \
--cell-max-cost-usd 2 \
--tasks runs/my-agent/tb21/tasks \
--verifier-authority runs/my-agent/tb21/cache/build/offline-verifier-authority.json \
--docker-inner-address-pool base=10.128.0.0/12,size=24
```
This generates `runs/my-agent/runtime.toml` without model calls. For Terminal-Bench, choose an address pool unused by your Docker network. `--cell-max-cost-usd` sets the benchmark task's cost threshold; an in-flight call can exceed it. The coding worker uses its own configuration from ①.
To use different models for individual roles, edit the generated TOML before step ④; the [configuration reference](../../configs/README.md#policy) lists the fields. UCB-based Policy Learning (`policy.method = "ucb"`) updates outcome statistics instead of textual lessons, requires a calibrated policy configuration, and is described there.
<a id="run"></a>
## ④ Start improving
Collect the starting program's visible-task results:
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-arena-baseline \
--config runs/my-agent/runtime.toml \
--output runs/my-agent/baseline \
--env-file .env --execute \
--budget-usd 50 --cell-allowance-usd 0.25 \
--task-pool runs/my-agent/task-pool
```
Then start improvement:
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-arena-research \
--config runs/my-agent/runtime.toml \
--evidence runs/my-agent/baseline/packet \
--output runs/my-agent/search \
--env-file .env --execute \
--budget-usd 250 --call-allowance-usd 0.50 --cell-allowance-usd 0.25 \
--task-pool runs/my-agent/task-pool
```
These commands make model calls, with separate example budgets of USD 50 for initial evaluation and USD 250 for research. Set these budgets and per-call reservation estimates for your workload; they are not price estimates or hard limits on in-flight calls. Both commands default to one benchmark task at a time.
<a id="results"></a>
View progress and results:
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-webui --research-root runs/my-agent/search --serve
```
Open the printed URL. Results are also saved as `session-result.json` and `accepted-artifacts.json` in `runs/my-agent/search`. After an interruption, repeat the research command with `--resume`, keeping its configuration and output unchanged. [Advanced options](docs/research.md).

# Legacy Campaigns
Reference for the original `agentpilot-arena launch` workflow. It uses the legacy Codex worker. For native/provider workers, follow the [current setup guide](../README.md). Complete the [repository installation](../../../../README.md#quick-start-harness) first. Run commands from the repository root in one Bash session, and use separate run and trace directories for each workflow.
The method identifiers `memory` and `ucb` select Textual Policy Learning and UCB-based Policy Learning.
<a id="aime"></a>
## AIME
### ① Set paths and models
Copy the preparation template:
```bash
mkdir -p runs/aime
cp agentpilot/integrations/arena/examples/aime-build.env.example runs/aime/build.env
chmod 600 runs/aime/build.env
```
Fill in the paths, revisions, model IDs, and limits in `runs/aime/build.env`. Fill campaign run IDs before launch; UCB-only fields are needed only for UCB. Set `TRACE_ROOT` to a new, empty directory reserved for this run; do not reuse traces from another research or legacy run. Keep API keys in the repository-root `.env`; `PROVIDER_KEY_ENV` names the variable containing the key. Docker and bubblewrap are required for benchmark execution.
```bash
set -a
. runs/aime/build.env
set +a
ARENA_ROOT="$REPOSITORY_ROOT/arena"
INTEGRATION_ROOT="$REPOSITORY_ROOT/agentpilot/integrations/arena"
INTEGRATION_PYTHON="$INTEGRATION_ROOT/.venv/bin/python"
INTEGRATION_CLI="$INTEGRATION_ROOT/.venv/bin/agentpilot-arena"
CONFIG_ROOT="$EXPERIMENT_ROOT/config"
RUNTIME_ROOT="$EXPERIMENT_ROOT/state"
TASKS_ROOT="$EXPERIMENT_ROOT/tasks"
ROOT_BASELINE="$EXPERIMENT_ROOT/root-baseline.json"
ENV_FILE="$REPOSITORY_ROOT/.env"
export PYTHONPATH="$REPOSITORY_ROOT/agentpilot/integrations/arena/src:$REPOSITORY_ROOT/arena/src:$REPOSITORY_ROOT/agentpilot/src"
export DOCKER_HOST="$AIME_DOCKER_HOST"
```
### ② Prepare Harbor and the program
Keep the trusted Harbor checkout separate from the program to improve. For existing checkouts, verify the revisions instead of cloning again.
```bash
git clone "$HARBOR_REMOTE" "$TRUSTED_HARBOR_ROOT"
git -C "$TRUSTED_HARBOR_ROOT" checkout --detach "$HARBOR_REVISION"
uv sync --project "$TRUSTED_HARBOR_ROOT" --locked --python 3.12
git clone "$HARBOR_REMOTE" "$PROGRAM_REPOSITORY"
git -C "$PROGRAM_REPOSITORY" checkout --detach "$HARBOR_REVISION"
```
`ROOT_COMMIT` must match the clean program checkout; `TRUSTED_HARBOR_COMMIT` and `TRUSTED_HARBOR_TREE` must match the trusted checkout. Keep these revisions, `ROOT_AVAILABLE_AT`, and the supplied build overlay unchanged when reusing measurements.
### ③ Build the task environment
Load the complete builder arguments below and run the bootstrap build. It creates the task tree and pins the shared AIME image; it does not call a model. Measure the starting program before generating the campaign configuration.
```bash
BUILD_ARGS=(
--split-manifest "$SPLIT_MANIFEST"

install -d -m 0700 "$CONFIG_ROOT" "$RUNTIME_ROOT"
git -C "$PROGRAM_REPOSITORY" worktree prune
"$INTEGRATION_PYTHON" -m agentpilot_arena.aime.build_experiment \
"${BUILD_ARGS[@]}" \
--method memory
"$INTEGRATION_PYTHON" -m agentpilot.app validate-config \
--config "$CONFIG_ROOT/$NAME_PREFIX-bootstrap.toml"
```
#### Measure the starting program
Run one task first, then resume the same checkpoint for the remaining visible-A tasks. These commands call the task solver.
```bash
"$INTEGRATION_PYTHON" -m agentpilot_arena.aime.measure_root \
--config "$CONFIG_ROOT/$NAME_PREFIX-bootstrap.toml" \
--split-manifest "$SPLIT_MANIFEST" \
--output "$ROOT_BASELINE" \
--env-file "$ENV_FILE" \
--limit 1
```
```bash
"$INTEGRATION_PYTHON" -m agentpilot_arena.aime.measure_root \
--config "$CONFIG_ROOT/$NAME_PREFIX-bootstrap.toml" \
--split-manifest "$SPLIT_MANIFEST" \
--output "$ROOT_BASELINE" \
--env-file "$ENV_FILE"
```
Continue when the summary reports `"complete": true` with no invalid cells. If the program or measurement settings change, collect a new baseline. Never run two writers against the same output.
#### Generate the measured configuration
Generate the measured Textual config and its matching Arena companion:
```bash
"$INTEGRATION_PYTHON" -m agentpilot_arena.aime.build_experiment \
"${BUILD_ARGS[@]}" \
--method memory \
--root-baseline "$ROOT_BASELINE"
"$INTEGRATION_PYTHON" -m agentpilot.app validate-config \
--config "$CONFIG_ROOT/$NAME_PREFIX-memory.toml"
```
#### Optional: also generate UCB
UCB additionally needs an accepted semantic calibration bundle and the OpenRouter management-key variable named by `MANAGEMENT_KEY_ENV`. With those fields set in `build.env`, regenerate both configurations:
```bash
: "${SEMANTIC_CALIBRATION_BUNDLE:?}"
: "${MANAGEMENT_KEY_ENV:?}"
UCB_ARGS=(
--semantic-calibration-bundle "$SEMANTIC_CALIBRATION_BUNDLE"
--management-key-env-name "$MANAGEMENT_KEY_ENV"
)
"$INTEGRATION_PYTHON" -m agentpilot_arena.aime.build_experiment \
"${BUILD_ARGS[@]}" \
"${UCB_ARGS[@]}" \
--root-baseline "$ROOT_BASELINE"
for method in memory ucb; do
"$INTEGRATION_PYTHON" -m agentpilot.app validate-config \
--config "$CONFIG_ROOT/$NAME_PREFIX-$method.toml"
done
```
#### Launch, resume, and finalize
Set `MEMORY_RUN_ID` and `MEMORY_ARENA_RUN_ROOT` in `build.env` and reload their values. Keep the generated config and its same-stem `.arena.toml` and `.authority.json` files together.
```bash
install -d -m 0700 "$RUNTIME_ROOT"
git -C "$PROGRAM_REPOSITORY" worktree prune
```
```bash
"$INTEGRATION_CLI" launch \
--config "$CONFIG_ROOT/$NAME_PREFIX-memory.toml" \
--arena-run-root "$MEMORY_ARENA_RUN_ROOT" \
--benchmark aime \
--run-id "$MEMORY_RUN_ID" \
--env-file "$ENV_FILE"
```
After interruption, replace `launch` with `resume` and keep the same arguments. Do not launch again into an existing run root. For UCB, use its generated config and separate `UCB_RUN_ID` and `UCB_ARENA_RUN_ROOT` values.
After the campaign completes, audit it and evaluate its selected candidate on held-out C:
```bash
"$INTEGRATION_PYTHON" -m agentpilot.app audit-campaign \
--config "$CONFIG_ROOT/$NAME_PREFIX-memory.toml" \
--run-id "$MEMORY_RUN_ID"
```
```bash
"$INTEGRATION_CLI" finalize \
--config "$CONFIG_ROOT/$NAME_PREFIX-memory.toml" \
--arena-run-root "$MEMORY_ARENA_RUN_ROOT" \
--benchmark aime \
--run-id "$MEMORY_RUN_ID" \
--env-file "$ENV_FILE"
```
Add `--retry-inconclusive` to `finalize` to retry inconclusive C tasks. C results do not update the improvement policy.
If a killed process left an action claimed, confirm its lease has expired and its processes or containers have stopped before using `agentpilot-arena-recover-action` with the original config, run ID, action ID, and parent commit. Reuse the run's database and workspace together when resuming.
<a id="tb21"></a>
## Terminal-Bench 2.1
### ① Set paths and models
Copy the preparation template:
```bash
mkdir -p runs/tb21
cp agentpilot/integrations/arena/examples/tb21-build.env.example runs/tb21/build.env
chmod 600 runs/tb21/build.env
```
Fill in paths, revisions, models, and limits in `runs/tb21/build.env`. The task revision must match the freeze's `source_reference`. Fill campaign run IDs before launch; UCB-only fields are needed only for UCB. Set `TRACE_ROOT` to a new, empty directory reserved for this run; do not reuse traces from another research or legacy run. Keep API keys in the repository-root `.env`; `PROVIDER_KEY_ENV` names the variable containing the key.
```bash
set -a
. runs/tb21/build.env
set +a
ARENA_ROOT="$REPOSITORY_ROOT/arena"
INTEGRATION_ROOT="$REPOSITORY_ROOT/agentpilot/integrations/arena"
INTEGRATION_PYTHON="$INTEGRATION_ROOT/.venv/bin/python"
INTEGRATION_CLI="$INTEGRATION_ROOT/.venv/bin/agentpilot-arena"
CONFIG_ROOT="$EXPERIMENT_ROOT/config"
RUNTIME_ROOT="$EXPERIMENT_ROOT/state"
ROOT_BASELINE="$EXPERIMENT_ROOT/root-baseline.json"
```
### ② Prepare task and program checkouts
Keep the trusted Harbor checkout separate from the program to improve. For existing checkouts, verify that their revisions match `TB2_REVISION` and `HARBOR_REVISION` instead of cloning again.
```bash
git clone "$TB2_REMOTE" "$TB2_REPOSITORY"
git -C "$TB2_REPOSITORY" checkout --detach "$TB2_REVISION"
git clone "$HARBOR_REMOTE" "$TRUSTED_HARBOR_ROOT"
git -C "$TRUSTED_HARBOR_ROOT" checkout --detach "$HARBOR_REVISION"
uv sync --project "$TRUSTED_HARBOR_ROOT" --locked --python 3.12
git clone "$HARBOR_REMOTE" "$PROGRAM_REPOSITORY"
git -C "$PROGRAM_REPOSITORY" checkout --detach "$HARBOR_REVISION"
"$DOCKER_EXECUTABLE" --host "$BENCHMARK_DOCKER_HOST" info
```
Use the same `BENCHMARK_DOCKER_HOST` throughout preparation and execution. Its Docker daemon must see repository and runtime directories at the same absolute paths as the host.
### ③ Prepare the task images
The first call downloads verifier dependencies and builds the pinned images. Later calls reuse or repair the prepared environment. This step does not call a model.
```bash
"$INTEGRATION_PYTHON" -m rsi_arena.benchmarks.tb21.closure_builder prepare \
--task-repository "$TB2_REPOSITORY" \
--cache-dir "$TB2_CLOSURE_CACHE" \
--temp-dir "$TB2_PREPARE_TMPDIR" \
--verifier-timeout-multiplier "$VERIFIER_TIMEOUT_MULTIPLIER" \
--docker "$DOCKER_EXECUTABLE" \
--docker-host "$BENCHMARK_DOCKER_HOST"
```
The complete 89-task cache can be large. For image distribution and cache details, see the [offline environment reference](../../../../arena/docs/tb21-offline-verifier.md).
### ④ Build the bootstrap configuration
Load the builder arguments below and run the bootstrap build. It prepares the visible-A/adaptive-B task directory and a bootstrap TOML. Measure the starting program before generating the campaign configuration.
```bash
BUILD_ARGS=(
--freeze "$FREEZE_PATH"
--output-dir "$CONFIG_ROOT"
--tb2-repository "$TB2_REPOSITORY"
--trusted-harbor-root "$TRUSTED_HARBOR_ROOT"
--program-repository "$PROGRAM_REPOSITORY"

#### Measure the starting program
Set `ROOT_CONCURRENCY` in `build.env`. Run one task first, then resume the same checkpoint for the remaining visible-A tasks. These commands call the task solver.
```bash
"$INTEGRATION_PYTHON" -m agentpilot_arena.tb2.measure_root \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory-bootstrap.toml" \
--output "$ROOT_BASELINE" \
--env-file "$REPOSITORY_ROOT/.env" \
--concurrency 1 \
--limit 1
```
```bash
"$INTEGRATION_PYTHON" -m agentpilot_arena.tb2.measure_root \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory-bootstrap.toml" \
--output "$ROOT_BASELINE" \
--env-file "$REPOSITORY_ROOT/.env" \
--concurrency "$ROOT_CONCURRENCY"
```
Continue when the summary reports `"complete": true`. Repeating the command retries unfinished measurements. Changing the program, task images, models, or measurement settings requires a new baseline.
#### Generate the measured configuration
Generate the measured Textual config and its matching Arena companion:
```bash
"$INTEGRATION_PYTHON" -m agentpilot_arena.tb2.build_experiment \
"${BUILD_ARGS[@]}" \
--method memory \
--root-baseline "$ROOT_BASELINE"
"$INTEGRATION_PYTHON" -m agentpilot.app validate-config \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory.toml"
```
#### Optional: also generate UCB
UCB additionally needs an accepted semantic calibration bundle and the OpenRouter management-key variable named by `MANAGEMENT_KEY_ENV`. With those fields set in `build.env`, regenerate both configurations:
```bash
: "${SEMANTIC_CALIBRATION_BUNDLE:?}"
: "${MANAGEMENT_KEY_ENV:?}"
UCB_ARGS=(
--semantic-calibration-bundle "$SEMANTIC_CALIBRATION_BUNDLE"
--management-key-env "$MANAGEMENT_KEY_ENV"
)
"$INTEGRATION_PYTHON" -m agentpilot_arena.tb2.build_experiment \
"${BUILD_ARGS[@]}" \
"${UCB_ARGS[@]}" \
--root-baseline "$ROOT_BASELINE"
"$INTEGRATION_PYTHON" -m agentpilot.app validate-config \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory.toml"
"$INTEGRATION_PYTHON" -m agentpilot.app validate-config \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-ucb.toml"
```
#### Launch, resume, and finalize
Set `MEMORY_RUN_ID` and `MEMORY_ARENA_RUN_ROOT` in `build.env` and reload their values. Keep the generated config and its same-stem `.arena.toml` and `.authority.json` files together.
```bash
install -d -m 0700 "$RUNTIME_ROOT"
git -C "$PROGRAM_REPOSITORY" worktree prune
"$INTEGRATION_CLI" launch \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory.toml" \
--arena-run-root "$MEMORY_ARENA_RUN_ROOT" \
--benchmark tb2 \
--run-id "$MEMORY_RUN_ID" \
--env-file "$REPOSITORY_ROOT/.env"
```
After interruption, replace `launch` with `resume` and keep the same arguments. For UCB, use its generated config and separate `UCB_RUN_ID` and `UCB_ARENA_RUN_ROOT` values. Keep existing databases and workspaces together when resuming.
After the campaign completes, audit it and evaluate its selected candidate on held-out C:
```bash
"$INTEGRATION_PYTHON" -m agentpilot.app audit-campaign \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory.toml" \
--run-id "$MEMORY_RUN_ID"
```
```bash
"$INTEGRATION_CLI" finalize \
--config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory.toml" \
--arena-run-root "$MEMORY_ARENA_RUN_ROOT" \
--benchmark tb2 \
--run-id "$MEMORY_RUN_ID" \
--env-file "$REPOSITORY_ROOT/.env"
```
Add `--retry-inconclusive` to `finalize` to retry inconclusive C tasks. C results do not update the improvement policy.
To supervise both generated policies through a user systemd manager:
```bash
systemctl --user is-system-running
"$INTEGRATION_PYTHON" -m agentpilot_arena.tb2.launch_dual \
--memory-config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-memory.toml" \
--ucb-config "$CONFIG_ROOT/$CONFIG_NAME_PREFIX-ucb.toml" \
--memory-run-id "$MEMORY_RUN_ID" \
--ucb-run-id "$UCB_RUN_ID" \
--memory-arena-run-root "$MEMORY_ARENA_RUN_ROOT" \
--ucb-arena-run-root "$UCB_ARENA_RUN_ROOT" \
--env-file "$REPOSITORY_ROOT/.env" \
--python "$INTEGRATION_PYTHON" \
--workdir "$ARENA_ROOT" \
--output-root "$EXPERIMENT_ROOT/supervisor"
```
If a killed process left an action claimed, confirm its lease has expired and its processes or containers have stopped before using `agentpilot-arena-recover-action` with the original config, run ID, action ID, and parent commit.
- Missing task image: rerun the image preparation command to restore its pinned image; avoid pulling a mutable replacement tag.
- Removed runtime worktrees: stop the affected run and use `git -C "$PROGRAM_REPOSITORY" worktree prune` before a fresh run.
- Missing SQLite parent directory: recreate `RUNTIME_ROOT`; do not combine a new empty runtime with old databases or run IDs.
- Empty policy output: select a model route that supports the required structured response and regenerate the config.

# Prepare Inputs and Continue AgentPilot
Use this step when the initial program or evaluation is missing. Reuse compatible inputs and implemented adapters; a dataset or test command alone is not a runnable AgentPilot environment. Generic adapter development is a separate task. Working configurations can continue through the normal [setup and run guide](../README.md).
## Prepare with the current agent
In the installed [integration environment](../../../../README.md#quick-start-harness), generate a preparation prompt:
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-arena-prepare \
--goal "Prepare the starting program and comparable evaluation for the actual task" \
--output runs/my-agent/preparation
```
Add `--program /path/to/program` or `--eval /path/to/evaluation` for existing inputs. Read the generated `prompt.md` and complete it with the current coding agent. Keep supplied inputs unchanged; put adaptations in a separate workspace. Reuse a suitable clean program revision and preserve the user's edits and commit restrictions. If the required revision or adapter is unavailable, record the missing prerequisite instead of silently creating a commit or changing the task.
To delegate preparation to an already configured worker, add `--worker-config /path/to/worker.toml --execute`, and optionally the configured `--env-file`. This makes one worker call; it does not start improvement. Worker charges remain external, and its reservation is neither a hard cap nor a verified bill. A separate worker is unnecessary when the current agent is preparing the inputs.
Use a fresh `--output`; existing directories are not overwritten and failed worker calls are not retried automatically. Preserve useful files and complete the same delivery before checking it:
```bash
uv run --project agentpilot/integrations/arena --no-sync agentpilot-arena-prepare \
--check runs/my-agent/preparation/prepared.json
```
## Delivery and readiness
| File | Purpose |
| --- | --- |
| `prompt.md`, `request.json` | Preparation instructions and original request. |
| `prepared.json` | Program revision, evaluation route, artifact paths and provenance, or a blocked result. |
| `PREPARATION.md` | Installation, actual smoke commands/logs, metric and comparison protocol, missing settings and runner invocation. |
| `worker-result.json` | Diagnostics and external accounting for delegated preparation. |
The `agentpilot-preparation/v1` handoff keeps evaluation resources outside the editable program. Paths resolve from the manifest directory. `--check` validates files, Git identity and configuration structure; it does not execute or certify the adapter.
Before improvement, verify that the implemented adapter uses the intended program and evaluator, and that their current identities match the actual smoke results. Evaluation must measure the user's objective with meaningful cases, comparable inputs and correctness constraints; noisy metrics need appropriate repeats. Ordinary correctness tests do not demonstrate a speedup. Preserve the adapter's development/comparison/held-out protocol.
Arena baseline `complete` can include invalid captures. Inspect measurements and diagnostics: a valid wrong answer or zero score is usable evidence; unresolved apparatus failures can make the intended comparison unmeasurable. Unknown charges remain unknown, never zero. Ensure the existing provider, worker, environment and authorized budget are available. The research runner can [reuse worker login](workers.md#reuse-the-worker-for-proposer-and-policy-calls) for proposer and Memory policy calls; task evaluation and UCB embeddings still require their configured providers.
## Continue into the real runner
When inputs and prerequisites are ready within the user's request, the current agent must invoke the configured AgentPilot runner, rather than only print a command or continue its own optimization loop. AgentPilot owns direction selection, worker dispatch, evaluation and policy feedback. If readiness cannot be established, report preparation incomplete and the specific missing prerequisite.
For Harbor/Terminus 2 on AIME or Terminal-Bench 2.1, use `evaluation.kind = "arena_setup"`. Import the handoff with `agentpilot-arena-setup --prepared /path/prepared.json` and the existing worker/model/environment choices from the [setup guide](../README.md#policy). Then execute its [baseline and research commands](../README.md#run). Reuse matching existing runtime/evidence instead of repeating work. Use the user's existing or established budgets; guide amounts are examples, not defaults. Resume baseline collection with the same arguments and output, and research with the same configuration/evidence/output plus `--resume`.
For another task with an **implemented** adapter, use `evaluation.kind = "core_config"`. The [core environment binding](../../../docs/environment-adapters.md) must already provide program seeding, real worker execution, frozen paired evaluation and feedback. Install it in the selected environment and run its documented smoke check before the core commands:
```text
agentpilot validate-config --config /path/runtime.toml
agentpilot run --config /path/runtime.toml --run-id RUN --batch-id BATCH --rounds N
agentpilot resume --config /path/runtime.toml --batch-id BATCH
```
Use the configured run length and credentials. Preserve the original batch and configuration for recovery; fresh IDs start a new run. Custom core adapters are not automatically registered with the built-in Arena research CLI. If no compatible binding exists, deliver a blocked handoff and explain the adapter work needed.

# Advanced Research Reference
For installation, configuration, and a normal run, follow the [AgentPilot + Arena guide](../README.md#run). This reference is optional.
## Model Access
`--proposer-access auto` uses the proposer's configured API key when present and otherwise reuses the configured worker CLI's model/login. `--policy-access auto` applies the same rule independently to Memory ranking and summarization. Both default to `auto`; choose `worker` to require CLI reuse or `api` to require an API key. API failures never silently switch routes. All supported worker backends use the same [completion contract](workers.md#reuse-the-worker-for-proposer-and-policy-calls).
Access choices and effective role models are saved in `completion-routes`. Resuming preserves them; if newly available credentials change automatic selection, explicitly select the original access mode or start a new output directory. CLI calls retain their per-call budget allowances and record external billing, without inventing a per-call price. Task evaluation and UCB embeddings still need their configured providers.
## Research Tools
| Tool | Behavior |
| --- | --- |
| `experiment(instruction=...)` | Run a worker experiment; retain its report, scripts, receipts, and source changes. A/B evaluation is not automatic. |
| `read_experiment(ticket="X1")` | Read a result; omit the ticket to browse history, or use `track="T1"` for a research line's current judgment and evidence. |
| `list_cases(view="tasks")` | Read visible-A task requirements without answers, outcomes, or trace bodies. |
| `build(instruction=...)` | Implement and check a candidate, then automatically compare it with the working version on B when admission is configured. |
| `build(from_experiment="X1", instruction=...)` | Adopt an experiment's retained source changes before finishing the candidate. |
| `evaluate(artifact="C1")` | Compare an existing candidate on B without rebuilding it. |
| `note`, `drop`, `close` | Save a judgment, stop new work on a track, or end the conversation while retaining running jobs and results. |
Experiments can call configured proposer/solver models through host-managed helpers and explicitly request visible-A measurements, including task subsets. Citing an experiment in build instructions passes its findings; `from_experiment` also adopts its edits. Temporary edits become candidates only through a build. Local findings inform research and direction ranking in Textual Policy Learning; valid B comparisons provide effectiveness observations. Experiment tools expose limited B summaries and no raw B or held-out C material.
## Judgments and Asynchronous Work
The proposer reads task requirements and source, then records a provisional explanation or capability idea, an alternative, and evidence that could refute it. A single task, a local repair, or a broader capability change is a valid scope. There is no mandatory hypothesis form or gate on trace reads. Contradictory findings should revise or end a research line.
`note(text=..., track="new")` creates a T identifier. Later notes record changed judgments, uncertainty, and supporting X tickets. Unassociated notes remain session notes. Requirements come from task briefs or recorded initial user input, with truncation marked; later agent explanations are not treated as requirements.
Independent reads and jobs can continue while an experiment runs. When the next decision needs its result, a nonempty assistant note without tool calls yields execution. The controller saves that wait and wakes when work completes; waiting does not spend model calls on polling.
Saved judgments have three consumers:
- Later proposer requests receive relevant judgments and result previews, including after compaction.
- Workers receive related judgments and cited reports, scripts, and outputs. Submitted worker inputs are frozen across restarts.
- The inspector shows worker observations separately from proposer judgments; it does not generate another narrative.
A completed experiment does not prove its hypothesis. Commits, tracks, tickets, and session checkpoints persist independently.
## Observation Modes
Add these flags to the [research command](../README.md#run). Both observation modes require `--execute`, make real model calls, and need their own `--output` directory. An existing output cannot switch between observation and normal research modes.
| Flag | Behavior |
| --- | --- |
| `--proposer-only` | Record source/trace reads and notes; stop before experiment, build, or evaluation dispatch. Historical evidence need not match the current measurement apparatus. |
| `--experiments-only` | Run experiments and return results to the proposer; stop before builds or B admission. Visible-A task measurements are allowed. |
| `--turns` | In experiments-only mode, bound investigation calls before the first completed experiment. |
| `--feedback-turns` | Reserve post-result calls in experiments-only mode; default 16. |
| `--max-experiments` | Bound submitted experiments in experiments-only mode; default 2. |
Experiments-only checks the runtime/tasks and records historical and current measurement identities without relabeling results or relaxing B validation. Limits persist across resume; launched jobs settle after an observation boundary. Proposer-only saves `proposer-input.json`, `proposer-observations.json`, `proposer-conversation.json`, and `session-result.json`; requested work has not executed.
## Recovery
- `--resume` continues the saved conversation with the same configuration, evidence, model, and output. `--session NAME` starts a new conversation; `--rounds` plans a persisted sequence.
- Completed measurements and durable receipts are reused. An unknown in-flight outcome needs reconciliation; missing receipts neither mean zero cost nor authorize another request.
- Reservations are estimates, and in-flight calls settle at actual cost. Changing a frozen runtime or measurement apparatus requires a separate run.
- Legacy measurement hashes are not rewritten; use their original environment or collect a new baseline.
<details>
<summary>Optional: fixed-profile multi-benchmark studies</summary>
`run_formal_research.py` uses fixed model profiles and frozen source for policy studies; it is not the normal installation path. Inspect generated TOMLs and `experiment.json` before dispatch.
From the repository root:
```bash
uv run --project agentpilot/integrations/arena --no-sync python agentpilot/experiments/run_formal_research.py prepare --output runs/formal-research --aime-config /path/to/aime-runtime.toml --tb21-config /path/to/tb21-runtime.toml
uv run --project agentpilot/integrations/arena --no-sync python agentpilot/experiments/run_formal_research.py preflight --output runs/formal-research --benchmarks aime tb21 --methods memory --rounds 5 --budget-usd 200
```
Replace `preflight` with `run` and add `--env-file .env` to execute; use `resume` with the original settings to continue. Here USD 200 is allocated per benchmark, including its shared baseline. `--baseline-repeats` sets A repetitions, and a shared task pool limits concurrency. `reconcile` retrieves existing receipts without new inference.
UCB requires `--ucb-calibration`. Optional `--provider-selection` freezes routes and output limits; `--host-tmpdir` selects a short directory for local sockets.
</details>
Use the [progress viewer](../README.md#results) to inspect jobs, judgments, lineage, code changes, policy and accounting. For formal studies, set `--research-root runs/formal-research`.
For existing single-action campaigns, see the [legacy campaign reference](legacy-campaigns.md).

# Prepare Terminal-Bench 2.1 Tasks
Complete the program and evaluator checkouts in [② Program and tasks](../README.md#program), then run these commands from the repository root. This step prepares tasks and images without model calls.
## Prepare the task checkout
```bash
mkdir -p runs/my-agent/tb21
git clone https://github.com/harbor-framework/terminal-bench-2-1.git runs/my-agent/tb21/tasks
git -C runs/my-agent/tb21/tasks checkout --detach 5c8eadf1f393183288fa08b8f73ca9a469cc5e00
```
For an existing checkout at this revision, reuse its path in the commands below.
## Prepare the task images
```bash
uv run --project agentpilot/integrations/arena --no-sync python -m rsi_arena.benchmarks.tb21.closure_builder prepare \
--task-repository runs/my-agent/tb21/tasks \
--cache-dir runs/my-agent/tb21/cache \
--temp-dir runs/my-agent/tb21/cache/tmp \
--verifier-timeout-multiplier 2.0 \
--docker-host unix:///var/run/docker.sock
```
The first run downloads dependencies and builds images for the 89 tasks; later invocations reuse the cache. Keep enough disk space for the images and retained dependencies. Use the same Docker socket during setup and execution.
The output is `runs/my-agent/tb21/cache/build/offline-verifier-authority.json`. Continue to [③ Policy and model](../README.md#policy) and use its Terminal-Bench setup command.
For cache repair or image transfer, see the [offline environment reference](../../../../arena/docs/tb21-offline-verifier.md) and [image bundle reference](../../../../arena/docs/tb21-exact-image-bundle.md). Their commands use paths relative to `arena/`; use the absolute paths to your existing cache when following them.

# Connect a Worker
The worker runs your coding harness to edit code and conduct experiments. Save one configuration below as `runs/my-agent/worker.toml`:
| Mode | Model and login |
| --- | --- |
| `native` | Use the harness's existing configuration. |
| `provider` | Supply the model and provider for this run. |
After saving the file, continue to [② Program and tasks](../README.md#program). Setup reads this file when generating the runtime configuration.
The same configuration can run an optional [preparation task](preparation.md) to find a missing initial program or evaluation before setup. Its separate prompt includes the Arena measurement interfaces and the required handoff format.
<a id="native"></a>
## Use your harness's model and login
Install and sign in to the CLI, then set its executable path:
```toml
[worker]
backend = "codex"
mode = "native"
command = ["/absolute/path/to/codex"]
runtime_root = "/absolute/path/to/worker-runtime"
sandbox_backend = "host"
reservation_usd = 2.0
```
`runtime_root` stores temporary files outside your repository. Hermes additionally creates and removes a temporary profile beside its login profile. `host` uses the harness's own execution permissions. `reservation_usd` allocates a budget allowance per task.
Presets: `codex`, `claude_code`, `hermes`, `nanobot`, `codebuddy`, and `dsh`. Configure the CLI's permissions for unattended execution. For a custom config directory, add its variable, such as `CODEX_HOME`, to `env_allowlist`; add credential variables to `secret_env_names`.
<a id="provider"></a>
## Use a provider such as OpenRouter
Change the same worker table to `mode = "provider"`, then add:
```toml
[worker.provider]
name = "openrouter"
model = "vendor/model-id"
api_key_env = "OPENROUTER_API_KEY"
```
Supply `OPENROUTER_API_KEY` through your environment or the repository-root `.env`. Setup adds the key name to the generated configuration; the OpenRouter endpoint is filled in automatically.
For another compatible service, set `name` and `base_url`. Codex uses Responses, Claude Code uses Messages, and nanobot/CodeBuddy use compatible model endpoints. The Hermes preset supports OpenRouter.
<a id="custom-command"></a>
## Other harnesses (custom commands)
Use this when your harness has no built-in preset, such as a company-internal coding agent. Keep the `native` or `provider` mode selected above, and replace `backend` and `command` with:
```toml
backend = "command"
command = ["/absolute/path/to/my-worker", "--task-file", "{prompt_file}", "--cwd", "{workspace}", "--session-id", "{session_id}", "--state-dir", "{session_root}"]
```
Use your harness's actual noninteractive command and flags. This example passes a task file, working directory, fresh session ID and private state directory. The wrapper must start with empty history and put all conversation state and automatic memory in that directory. It must keep using its existing login/model configuration separately. Both session placeholders are required; an opaque command without an isolation binding is rejected.
If your wrapper takes session settings through environment variables, bind both instead:
```toml
[worker.session_env]
MY_SESSION_ID = "{session_id}"
MY_SESSION_DIRECTORY = "{session_root}"
```
The wrapper must actually consume these variables. AgentPilot can enforce fresh values and cleanup, but cannot enforce an arbitrary external program's internal behavior.
The task is sent on stdin by default. Use `{prompt}` or `{prompt_file}` when your CLI expects an argument. The harness must leave its code changes in `{workspace}` before exiting.
For provider mode, map all three values to variables your wrapper reads:
```toml
[worker.provider_env]
MY_MODEL = "{model}"
MY_BASE_URL = "{base_url}"
MY_API_KEY = "{api_key}"
```
DSH provider overrides also use a wrapper/profile that consumes these variables. Other presets configure the provider automatically.
## Session isolation
Proposer/policy calls and execution workers reuse authentication and model settings, with independent CLI conversations. Every launch, including retries and concurrent tasks, receives fresh session state. Known resume/continue/fork options and fixed session IDs are rejected, and inherited parent-session environment variables are removed. Built-in commands cannot contain an option terminator (`--`) before the runtime adds its isolation flags. Task prompts, repository files and evidence explicitly supplied by AgentPilot remain available.
| Backend | Isolation |
| --- | --- |
| Codex | `exec --ephemeral`, no prompt history, automatic memories disabled. |
| Claude Code / CodeBuddy | Fresh UUID, `--no-session-persistence`, automatic memories disabled. |
| Hermes | Disposable profile with its own history/memory store, memory providers disabled, native credential-pool fallback to the existing login. OAuth grants are not copied. A private `.env` projection removes session selectors and preserves explicit provider overrides without modifying the original. Select a source profile with allowlisted `HERMES_HOME`, rather than `--profile`. |
| nanobot | Fresh `--session`, private config-relative session store, explicit task workspace instead of the login's default workspace/memory. Proposer workspaces are empty; execution workspaces contain the task checkout. |
| DSH | One-shot `headless` profile and a final overlay isolating session, search and attachment storage. Login/model settings remain in the original DSH home. |
| Custom command | Explicit `{session_id}` and `{session_root}` bindings consumed by the wrapper. |
Use CLI versions supporting the listed flags and storage behavior (Hermes needs shared profile credential fallback; nanobot needs config-relative session storage). An unsupported CLI fails the call; the runtime does not retry it with isolation disabled. Temporary state is cleaned up after normal completion, launch failure and timeout. `host` is still the configured execution policy; session isolation does not restrict filesystem access.
## Reuse the worker for proposer and policy calls
The Arena **research** command defaults to `--proposer-access auto` and `--policy-access auto`. Each role uses its configured API credential when present; when that credential is absent, it invokes the configured worker CLI with the worker's model and login. This supports all seven backends above, in both `native` and `provider` mode. Authentication failures from an API do not trigger a switch to worker access.
To use the worker even when an API key is available, add these flags to the research command:
```bash
--proposer-access worker --policy-access worker
```
`--policy-access` controls Textual Policy Learning's ranker and summarizer. Use `api` instead of `auto` to require an API and fail immediately when its key is missing. The API key name comes from `environment.settings.provider_runtime.providers`; older OpenRouter configurations without a binding use the solver's configured key name.
Worker access preserves the worker's model/provider and generation settings. Set those in the worker CLI or `worker.toml`; do not pass a different `--model` or an API endpoint allowlist for these calls. Each call uses a fresh temporary directory and isolated CLI session, receives the conversation and tool definitions, and returns JSON. Proposer's multi-turn history is supplied explicitly by AgentPilot; execution-worker conversation history is never attached. AgentPilot validates and executes the requested proposer tools. Saved replies are replayed after interruption; a dispatched call without a receipt is not repeated. Keep the same access mode and worker profile when resuming a run.
Custom commands can write their JSON reply to the path in `AGENTPILOT_COMPLETION_OUTPUT` or return it on stdout. The supplied prompt describes the output contract. Built-in CLIs can also save `agentpilot-response.json` in their temporary workspace. No login tokens are copied into the runtime TOML or prompts.
CLI billing remains external: each completed call retains its budget reservation, with actual dollars unknown rather than zero. CLI token usage is recorded when reported. API temperature/output-token settings do not override the worker CLI's generation settings; timeout and response-byte limits still apply.
The benchmark task solver and UCB embedding model retain their own provider requirements. In particular, a full Arena run still needs the task-solver API; `--proposer-only` can inspect existing evidence using just worker login. Legacy single-action campaigns and custom core adapters keep their existing provider assembly.

"""Describe measured AIME cells for the trusted policy.
A recorded cell id says that some problem was failed, not which problem or what
it asked. A policy that only sees identifiers has to guess the failure
mechanism from a score, which is how a proposer ends up asking for a generic
"verification step" no matter what actually went wrong.
Statements come from ``PublicAimeTask``. Only visible-tier cells are
described at all: that tier is a labelled development set which seeds the
archive once and never decides an admission, so its statements, answers and
run excerpts cannot inflate a measured comparison. Wave cells decide
admissions, and their statements are withheld along with their answers --
AIME problems are public, so for a model that has seen the contest a
statement identifies the answer as surely as the answer itself. A failing
wave cell therefore appears in prompts only as an anonymised reference with
its observed failure mode.

"""Measure the unmodified root program on the visible-A census.
`root_seed.cell_results` and `root_seed.primary_value` are declared by config,
never derived by the framework, so the root baseline has to be produced once
before the first seeded run. This drives the same `AimeCellExecutor` the paired
evaluator uses, through the same launcher, against the root commit rather than
an action child.
Cells are measured concurrently at the same width the paired evaluator uses,
because a measurement depends only on its program id and its frozen cell and so
cannot be changed by overlapping with another. The document is rewritten after
every cell, so an interrupted sweep can be resumed with the same command.

"""The measured root baseline: what the unmodified program scored on visible A.
``root_seed.cell_results`` is declared by config and never derived by the
framework, so the root program has to be measured once before the first seeded
run. One script produces that measurement and another reads it back into
config, which is why the document's shape lives here rather than inside either
of them: a producer and a consumer each carrying their own copy of it drift
silently, and the drift only surfaces later as a config the settings parser
rejects, or worse, as a seeded value that is quietly wrong.
Cells are keyed by the canonical A-tier measurement name, the same name the
recorded results use, so the document needs no renaming on its way into config.
Every rule the seeded shape has to satisfy -- that only a failed cell has a
failure mode, that an excerpt stays inside the brief's bound -- is checked here,
at the point the record is built, rather than after a whole sweep has been paid
for.

Prepare the missing initial program and/or evaluation for the user's task using
an existing implemented AgentPilot adapter. This is preparation for the real
proposer/worker/evaluation runner, not a substitute improvement loop.
## User request
{request}
## Work to perform
1. Inspect any supplied program and evaluation first. Reuse compatible existing
inputs. Treat their locations as read-only: if adaptation is needed, make a
separate copy in this workspace. Fill only what is missing. Do not substitute
an unrelated benchmark just because an integration already exists.
2. Find suitable existing repositories, datasets, task definitions, and graders.
Use the harness's available search/network tools and record actual sources
and revisions. Prefer a small runnable baseline and an established evaluation
matching the user's goal. Prepare suitable inputs and checks for an existing
adapter; do not build a generic adapter or fabricate an unrelated benchmark
to make the handoff pass. Report a missing adapter as a blocked prerequisite.
3. Place new files and isolated dependency environments under this workspace.
Keep the editable program separate from evaluation code, tasks, and answers.
Pin downloaded repositories and dataset versions. The handoff requires a clean
Git program revision. Reuse a suitable existing revision while preserving the
user's edits and commit restrictions. Do not create a commit, even in a copy,
to bypass a prohibition; report this prerequisite if it cannot be met.
Do not change global harness configuration.
4. Run a small smoke check with visible development inputs when dependencies and
credentials permit. Record the exact command, observed result, and log path in
PREPARATION.md. Check meaningful cases, grader behavior, comparable inputs and
correctness constraints. Performance goals need actual measurements and an
appropriate repeat/noise policy; ordinary passing tests are insufficient.
Distinguish missing infrastructure from a valid measurement of a wrong answer.
Do not invent benchmark scores, passing tests, dataset hashes, or cost reports.
5. Write PREPARATION.md with the chosen program/evaluation, provenance, install
commands, entrypoint, editable code paths, metric meaning, dataset splits,
completed checks, remaining settings, and the runner command. Write
prepared.json using exactly one of the handoff formats below. A final chat
answer alone is not a handoff: the calling agent reads prepared.json from disk.
When acting as a standalone preparation worker, return this delivery to the
calling agent without launching a campaign. When acting as the current host for
the user's full AgentPilot request, validate the delivery and continue the actual
configured runner once evaluation, provider/worker, environment and budget
prerequisites are met within the existing authorization. Do not merely print the
next command or continue your own iterative code edits. Otherwise report
preparation incomplete and the specific missing prerequisites.
Verify current source/configuration/evaluator identities against actual smoke
evidence. Arena baseline status complete can include invalid captures: inspect
measurements and diagnostics before research. A valid zero score differs from
apparatus failure. Retain existing run identities and recovery records; do not
repeat paid work merely because billing remains pending. Unknown costs remain
unknown, not zero or the configured reservation.
Do not read or embed credential values in prompts, manifests, or logs. Reference
environment-variable names. Use the configured harness permissions for network
access; if source access is unavailable, report what remains missing.
## Route 1: existing Arena research setup
Use this route only for AIME 2024+2025 or Terminal-Bench 2.1 with a Harbor Terminus 2
program. Other Python projects do not become compatible by renaming a path.
The program checkout must contain src/harbor/agents/terminus_2. The trusted Harbor
checkout must be separate, clean, and have executable .venv/bin/python and
.venv/bin/harbor. Reuse the installed integration's documented formats:
- Setup and validation: {integration.joinpath('setup.py')}
- AIME task split: {integration.joinpath('aime', 'data', 'split.example.json')}
- TB2.1 freeze: {integration.joinpath('tb2', 'data', 'freeze.example.json')}
- TB2.1 preparation: {integration.joinpath('tb2', 'build_experiment.py')}
AIME tasks are bundled; the ordinary setup command prepares the task image.
For TB2.1 also supply the real task Git checkout and offline-verifier authority
produced by its preparation tools. Never fabricate an authority file. Docker
network selection, worker/model settings, and run budgets come from existing
configuration or the user's choices. Native worker login does not configure the
formal proposer/policy/task-model provider. Do not invent budgets or credentials.
The manifest for AIME is:
```json
{{
"schema": "agentpilot-preparation/v1",
"program": {{
"path": "program",
"revision": "ACTUAL_FULL_GIT_COMMIT_SHA",
"entrypoint": "builtin:terminus-2"
}},
"evaluation": {{
"kind": "arena_setup",
"benchmark": "aime",
"harbor": "evaluation/harbor"
}},
"sources": [
{{"url": "ACTUAL_SOURCE_URL_OR_LOCAL_PATH", "revision": "ACTUAL_REVISION", "path": "program"}},
{{"url": "ACTUAL_SOURCE_URL_OR_LOCAL_PATH", "revision": "ACTUAL_REVISION", "path": "evaluation/harbor"}}
]
}}
```
For TB2.1 set benchmark to "tb21" and add "tasks" and "verifier_authority" paths
inside evaluation. Do not add arbitrary command-line flags to the manifest.
The controller imports these paths through agentpilot-arena-setup --prepared.
## Route 2: an existing custom core adapter
Use an implemented core AgentPilot environment binding for the actual task. The
Arena research setup is specific to Harbor/AIME/TB2.1; changing a name in TOML
does not register a new benchmark. If no compatible binding exists, return a
blocked handoff. Developing a generic adapter is a separate task.
Check the existing adapter against these installed interfaces:
- {core.joinpath('app', 'bindings.py')}: AssemblyDependencies, ProviderRegistry,
BatchAssemblyContext, Environment, ActionRunnerBinding.
- {core.joinpath('app', 'search_read_model.py')}: seed the real initial program
and baseline with CanonicalSearchReadModelWriter.
- {core.joinpath('app', 'runtime_config.py')} and {core.joinpath('app', 'config.py')}:
runtime TOML schema.
The installed factory must return AssemblyDependencies and supply real program
seeding, worker execution, frozen paired evaluation, feedback and trace bindings.
A BenchAdapter, standalone test command or synthetic example alone is insufficient.
Keep the adapter/evaluator outside editable code, and retain its development,
comparison and held-out protocol. Parent and candidate must use comparable
tasks, seeds and budgets. Unknown costs remain unknown, never a fabricated zero.
Record missing model, credential-name, budget or environment settings. Check that
the adapter actually uses the delivered program and evaluator, and that current
versions match the smoke evidence. Static validation does not prove this. For
an existing runtime, preserve its configuration and use its actual smoke/run
procedure rather than substituting a host-driven loop.
The core handoff uses:
```json
{{
"schema": "agentpilot-preparation/v1",
"program": {{
"path": "program",
"revision": "ACTUAL_FULL_GIT_COMMIT_SHA",
"entrypoint": "your_program:run"
}},
"evaluation": {{
"kind": "core_config",
"config": "runtime.toml",
"adapter": "evaluation"
}},
"sources": [
{{"url": "ACTUAL_SOURCE_URL_OR_LOCAL_PATH", "revision": "ACTUAL_REVISION", "path": "program"}},
{{"url": "ACTUAL_SOURCE_URL_OR_LOCAL_PATH", "revision": "ACTUAL_REVISION", "path": "evaluation"}}
]
}}
```
Paths are relative to prepared.json, or absolute for reused existing inputs.
Replace every example placeholder with a real identity. Include the origin of
newly written code as a local source and give its actual version/revision.
If the required artifacts cannot be prepared, write a blocked handoff instead:
```json
{{
"schema": "agentpilot-preparation/v1",
"status": "blocked",
"missing": ["specific missing input or capability"],
"reason": "What was attempted and why preparation could not finish"
}}
```
Preserve useful completed work and explain how to continue in PREPARATION.md.

"""Safely recover one externally interrupted AgentPilot Arena action claim.
The action journal intentionally does not recycle ``claimed`` rows on lease
expiry: an evaluator may still be running. This operator tool provides the
missing explicit path for a process that was killed before it could persist a
terminal result. Uncommitted work is removed and released; a prepared commit
is moved to the single post-commit resume state without deleting its worktree.
The operation is fail-closed and requires the configured Docker daemon to have
