name: ledger-tasks-yylo
description: Comprehensive guide for using YYLO Ledger task management without bypassing controller routing, lifecycle state, or mutation receipts. Covers task commands, dependency management, best practices, and workflow patterns. Use when you need to interact with the YYLO Ledger board.
version: 1.0.0
license: MIT
argument-hint: "[command or workflow question]"
enable-shell-directives: true
---
## YYLO Ledger CLI Reference
Use `yy ledger` for all commands. Before any operation, run `yy ledger --version` and `yy ledger --help`; the installed runtime's help is authoritative. Read the current task/board state before mutation, preserve the returned mutation receipt when offered, and never edit Markdown/store files directly to bypass controller routing or lifecycle state. If the required command group is absent, stop and request a Ledger upgrade rather than guessing or invoking mutable source code. Ledger 0.3.x exposes both the compatible flat task commands and the native ID-first `record|task|wiki|workflow|artifact` groups. `yy kanban` is a labelled compatibility alias for the same controller-routed task runtime.
### Supported task contract
- Preflight installed `yy ledger --version` and `yy ledger --help`; command help is authoritative for the selected runtime.
- Use the flat task surface for lifecycle task management. Use the dedicated native skills for wiki, workflow, and artifact Records rather than guessing their arguments.
- New operational PDRs, contracts, plans, reports, receipts, and evidence belong in typed Artifact Records, not product documentation, task bodies/responses, or new `.juno_task/specs` files.
- If a required native group is absent, fail closed and request a Ledger upgrade. Never invoke mutable source directly or write Ledger store files by hand.
- Read current task state before mutation, preserve mutation receipts where offered, and never bypass controller routing or lifecycle state with direct file edits.
- Normal discovery is hot-only unless an explicit cold-archive command is used.
### Opt-in cross-project routing
Cross-project access is disabled by default. The source `.juno_task/config.json` must set `kanbanRegistry.enabled: true` and explicitly list `allowedProjects`; environment overrides are `YYLO_LEDGER_REGISTRY_ENABLED` and `YYLO_LEDGER_REGISTRY_ALLOWED_PROJECTS`. Register with `yy ledger project add ALIAS --path /absolute/project`, then route any command with `--project ALIAS`. The destination wrapper/runtime remains authoritative, and routing failures never fall back to the source board.
### Legacy Task compatibility commands
**CREATE** — Add a new task
```bash
yy ledger create "Task description here" --status backlog --tags feature,backend
```
Options: `--status` (backlog|todo|in_progress|done), `--tags` (comma/space-separated), `--blocked-by` (task IDs), `--related-tasks` (task IDs)
**LIST** — Browse tasks with summary stats
```bash
yy ledger list --limit 5 --sort asc
yy ledger list --status todo --sort asc
yy ledger list --status todo,in_progress --limit 10
```
**SEARCH** — Find tasks by criteria
```bash
yy ledger search --status todo --tag backend --limit 10
yy ledger search --body "OAuth" --open
yy ledger search --commit abc123
```
Filters: `--status`, `--tag`, `--body`, `--response`, `--commit`, `--open` (no agent_response), `--recent`, `--exclude` (exclude tags)
**GET** — Full task details (including dependency info and related task details)
```bash
yy ledger get TASK_ID
```
**MARK** — Update status with required response message
```bash
yy ledger mark in_progress --id TASK_ID --response "Starting work on this"
yy ledger mark done --id TASK_ID --response "Completed: implemented X, tested Y" --commit abc123def
yy ledger mark todo --id TASK_ID --response "Reopening: found regression"
```
Required: `--id` and `--response`. Optional: `--commit` (recommended for done).
**UPDATE** — Modify task fields
```bash
yy ledger update TASK_ID --status todo --tags backend,urgent
yy ledger update TASK_ID --commit abc123def
yy ledger update TASK_ID --response "Additional context"
```
**ARCHIVE** — Soft delete (preserves data, sets status to archive)
```bash
yy ledger archive TASK_ID
```
### Immutable cold archive packs
Normal `list`, `search`, `ready`, and `order` are deliberately hot-only. Exact `get TASK_ID` transparently resolves a hot task or a read-only archived task; use `history TASK_ID` explicitly for its ledger. Discover cold tasks only with bounded, projected `archive-search` output:
```bash
yy ledger archive-search --tag backend --before 2026-01-01 --limit 20 --projection metadata
```
Before archive maintenance, preflight the installed version/help and obtain explicit owner authorization. The repository and index must be clean, and reports must be durable new paths outside the repository:
```bash
yy ledger --version
yy ledger archive-pack plan --status done,archive --older-than 90d --max-tasks 1000 --target-bytes 26214400 --hard-max-bytes 47185920 --report /external/receipts/archive-plan.json
# Independently inspect selected IDs, revisions, source HEAD, policy, and plan hash.
yy ledger archive-pack create --plan /external/receipts/archive-plan.json --report /external/receipts/archive-create.json
yy ledger archive-pack doctor
yy ledger doctor
```
A stale plan or selected-task/worktree conflict must fail closed: discard the plan, resolve the conflict, and plan again. Never automate archival, edit/append packs or manifests, restore/reopen an archived ID, use force/lossy controls, or enumerate archive files directly. Create follow-up work as a new hot task related to the archived ID. Production archival, push/deploy, and post-deploy E2E each require separate authorization; agents must not infer it from implementation approval.
### Dependency Management
**DEPS** — View, add, or remove task dependencies
```bash
# View dependency info (blockers, dependents, priority score)
yy ledger deps TASK_ID
# Add blockers (TASK_ID cannot start until BLOCKER1 and BLOCKER2 are done)
yy ledger deps add --id TASK_ID --blocked-by BLOCKER1 BLOCKER2
# Remove a blocker
yy ledger deps remove --id TASK_ID --blocked-by BLOCKER1
```
Cycle detection prevents circular dependencies automatically.
**READY** — Tasks with all blockers satisfied (safe to work on)
```bash
yy ledger ready
yy ledger ready --tag backend --limit 5
```
Returns tasks where status is backlog/todo/in_progress AND all `blocked_by` tasks are done/archive.
**ORDER** — Topological sort of open tasks respecting dependencies
```bash
yy ledger order
yy ledger order --scores
```
Use for determining safe parallel execution order.
### Body Markup for Inline Dependencies
Declare dependencies and relations directly in task body text:
```
[blocked_by]TASK_ID[/blocked_by] — This task is blocked by TASK_ID
[blocked_by]ID1, ID2[/blocked_by] — Blocked by multiple tasks
[task_id]RELATED_ID[/task_id] — Reference a related task
[task_id]ID1 ID2[/task_id] — Multiple related tasks
```
These are parsed automatically when the task is created/updated.
### Merge (Multi-Directory Consolidation)
When tasks get scattered across subdirectories:
```bash
# First produce and review a deterministic plan
yy ledger merge ./sub1/.juno_task ./sub2/.juno_task --into ./.juno_task \
--dry-run --plan-file /external/ledger-merge-plan.json
# Apply only that reviewed plan and retain its receipt
yy ledger merge ./sub1/.juno_task ./sub2/.juno_task --into ./.juno_task \
--apply-plan /external/ledger-merge-plan.json \
--receipt-file /external/ledger-merge-receipt.json
```
### Output Formats
All commands support: `-f json`, `-f ndjson` (default), `-f xml`, `-f table`
Add `--raw` for compact output. Add `-p` for pretty print.
### Best Practices
1. **Task sizing**: Create tasks small enough to complete in one iteration without filling the context window
2. **Status flow**: backlog → todo → in_progress → done (or archive for abandoned tasks)
3. **Always include `--response`** when using `mark` — document what you did and how you tested it
4. **Attach commits**: Use `--commit HASH` when marking done, then `update TASK_ID --commit HASH` to link the git history
5. **Use `ready`** before starting work to find unblocked tasks
6. **Use `order --scores`** to plan parallel execution pipelines
7. **Use `[blocked_by]` markup** in task body when creating tasks that depend on others
8. **Use `[task_id]` markup** in task body to cross-reference related tasks
9. **Use `get TASK_ID`** to see full task details including resolved dependency and related task info
10. **Concurrent features are supported** — start each selected task with `yy task start TASK_ID`; each gets a dedicated product worktree, while `yy merge` serializes only target updates
### Canonical Controller Routing
YYLO Ledger mutation resolves the controller in this order: explicit `JUNO_TASK_ROOT`, repository-local registration, then the current project root. Diagnose before orchestration with `.juno_task/scripts/controller_resolver.py --cwd "$PWD" --operation kanban`. The resolver may bootstrap or idempotently confirm a registration, but changing an existing controller requires `yy migrate registration plan` followed by a separately authorized apply. Explicit/registered path or branch errors fail closed—YYLO Ledger never switches Git branches or falls back silently.
Run YYLO Ledger and workflows from the controller. A task checkout may implement/test but routes task/session writes to that controller. An integration-owner checkout stays clean and refuses Kanban/orchestration/session writes in strict mode; launch from the controller and pass the product checkout separately as `TASK_ROOT`.
### Environment Variables
- `JUNO_TASK_ROOT` — Explicit canonical controller/task-storage root (not the product `TASK_ROOT`)
- `JUNO_CONTROLLER_BRANCH` — Expected controller branch for environment-based routing
- `JUNO_WORKSPACE_ROLE``controller`, `task`, or `integration-owner`
- `JUNO_WORKSPACE_ENFORCEMENT``off`, `warn`, or `strict`
- `JUNO_DEBUG=true` — Show diagnostic messages
- `JUNO_VERBOSE=true` — Show informational messages
- `JUNO_KANBAN_LIST_BODY_TRUNCATE_CHARS=N` — Override list body truncation (default: 1200)

# Reading a recorded agent run
A recording is evidence. Your memory of a session is not, and neither is a transcript you were
handed — both are missing the tool results, the exit codes, and the files that changed without
anyone mentioning it.
**The rule: when a question is about something that already happened, read the trace before you
answer.** Do not reconstruct it. If a recording exists, guessing is the wrong move even when the
guess would have been right.
## When to Use This Skill
- "Why did you delete/overwrite/move X?"
- "What changed this file?" / "Which step broke the build?"
- "Can you reproduce yesterday's failure?"
- "Does this still reproduce?" (see the limit on that in step 4 — replay cannot tell you
whether a *fresh* run would fail again)
- "Would a different model have got this right?"
## Workflow
### 1. Find the run
`orca_list_runs` — newest first, and it names the run each fork came from. Skip this only when the
user clearly means the most recent one; every other tool defaults to `run: "last"`.
### 2. Narrow to the chain that produced the thing being asked about
`orca_show_run` gives the whole timeline: model turns with token counts and stop reasons, tool
calls with arguments and results, shell commands with exit codes, and every file the run changed.
Good for orientation, long for a specific question.
`orca_graph` is usually the better tool. It returns causal edges — which event produced which. Pass
`to: <event seq>` to get **only** the chain that produced one event. That is the shape of an answer
to "why did this happen", where the full timeline is the shape of an answer to "what happened".
### 3. Report `recorded` and `inferred` differently
Every edge from `orca_graph` is labelled:
- **`recorded`** — the recorder watched it happen and wrote it into the trace.
- **`inferred`** — derived just now from a rule the edge names. The trace does not vouch for it.
Carry that distinction into your answer. "The trace shows the `rm` at step 14 removed it" and "this
looks like the `rm` at step 14, going by timing" are different claims, and flattening them into one
confident sentence is the specific failure this tool exists to prevent. Name the rule when you lean
on an inferred edge.
### 4. Reproduce it before explaining it
`orca_replay` re-runs the recording and reports what could not be reproduced — divergences, and
requests the recording could not serve.
**What "offline" covers, and what it does not.** Every model response comes from the trace and the
proxy forwards nothing upstream, so no provider is contacted and no tokens are spent. An unmatched
request halts the replay rather than falling through to the network, unless `--loose` was asked for.
That covers the model traffic. It does not cover the agent's own subprocesses: unless the recording
used `--tls-intercept` — in which case replay re-establishes interception for the hosts it recorded
— a `curl`, `npm install`, `git push` or database call inside a recorded shell command goes
straight out. Replay is not a sandbox; only a network-isolated container makes it one.
**What a matching replay proves, and what it does not.** It shows the recorded decisions reproduce
against today's environment. It cannot show the failure is deterministic, because the model is not
being asked again — the same recorded responses are served back. If the user wants to know whether a
fresh run would fail the same way, say that replay cannot answer it; that needs real runs.
**Replay re-executes the agent, not just its model traffic.** The recorded model responses are
served from the trace, but the agent process runs again for real — so every shell command it issued
runs again too. `worktree: true` isolates repository files and nothing else. Anything the run
touched outside the tree — `/tmp`, Docker, a local database, a package manager, another host — is
mutated a second time.
**Hard gate before every replay.** Before calling `orca_replay`, the agent MUST use `orca_show_run` (or an equivalent trace view) to enumerate the complete shell-command list, including commands that may touch `/tmp`, Docker, databases, package managers, or remote hosts. It MUST show that list to the user and obtain explicit approval for the exact replay. If any command reaches outside the worktree, approval MUST name those external effects or the replay MUST run inside a genuinely isolated container. `worktree: true` protects repository files only; it does not authorize external side effects. Do not infer approval from silence, a previous approval, or the fact that the original run was recorded. A run that only read files and edited the repository is free and repeatable, but it still requires this preview-and-confirm gate.
**Pass `worktree: true`.** It replays into a scratch copy and leaves the working tree alone.
Without it, replay is destructive for as long as it runs: it restores the recorded filesystem over
the working tree and puts the tree back when the replay ends. Uncommitted work is absent in the
meantime, and stays absent if the replay is interrupted before it can restore. Run an in-place
replay only when the user has been told that and has agreed to it. "They do not appear to be
typing" is not consent.
A replay reporting `reused=3/5` on an interactive recording is not a partial failure. Harnesses make
calls for themselves — a quota probe, a session-naming request — and a replay does not repeat them.
### 5. Only then consider comparing models
`orca_compare` forks one run onto several models from the same checkpoint: same files, same
conversation prefix, so the model is the only variable. Pick the fork point with `orca_checkpoints`
and pass it as `from`.
Grade with `verify` — a shell command whose exit code is the verdict. Use something the repository
already declares (`"npm test"`, `"npm run typecheck"`) or an explicitly local binary
(`"./node_modules/.bin/tsc --noEmit"`), not `npx <tool>`: with no local install, npx runs whatever
the registry has under that name, and `npx tsc` resolves a package deprecated in 2016 that is not
TypeScript.
**`orca_compare` uploads the recording to other people's models, and spends real money doing it.**
Each model named receives the same files and conversation prefix the original run had — so whatever
that run touched (source, prompts, configuration, anything a credential was pasted into) is sent to
every provider behind those model ids.
**And each fork is a live agent, not a replay.** From the fork point onward the model is really
being asked, and whatever it decides to do, it does — its shell commands execute for real, and so
does the `verify` command you pass. Each fork gets its own worktree, so repository files are
isolated per model; nothing outside the tree is. A fork can also take actions the original run never
took, because it is a different model making fresh decisions.
So the approval has three parts, and they are not the same question:
1. **Disclosure** — what context is uploaded, and to which providers. Approving a bill is not
approving a disclosure, and the two need separate answers when the recording is from a private
codebase. `orca scrub` is for when the comparison is worth running but the trace is not safe to
send as-is.
2. **Side effects** — what the recorded run did outside its worktree, since each fork may repeat it
and may go further. Same check as step 4, `orca_show_run`, and the same answer if it reached
Docker, a database, a deployment or another host: get approval for that specifically, or run the
comparison in an isolated environment.
3. **Cost** — how many models times how many forks.
Never run it to satisfy curiosity the user did not express.
## If there is no recording yet
Say so plainly rather than falling back to guessing, and offer to start one.
If `orca` is already installed:
```console
orca record claude # or codex, opencode, openclaw, grok
```
If it is not installed, stop and ask the user to install it separately. Do not install packages, change global state, or use a package-manager command as part of this Skill.
`orca record <agent>` runs the agent unmodified behind a local proxy. Nothing about the agent
changes; two environment variables get set. Recording a session now is what makes the next "why did
it do that" answerable.
For a run started with a prompt in argv — `orca record claude -- -p "…"` — the replay is exact. A
session someone typed into replays approximately, because the prompts were never on the wire and
are recovered from the harness's own transcript; `orca replay` says which is which rather than
papering over it.
## Sharing a run with someone else
`orca export last -o run.html` writes one self-contained file. A trace holds whatever the run held,
so run `orca scrub` before sending one anywhere.
Scrubbing is best-effort, not a guarantee. It matches known key shapes and high-entropy strings; it
cannot know that a particular internal hostname, customer name, or unreleased feature is
confidential to this user. So scrub, then have the user look at what is actually going out, and get
their agreement — do not describe a scrubbed trace as safe on the strength of the scrubber alone.
## Limitations
- **It only sees what was recorded.** Runs started without `orca record` leave no trace, and
nothing here recovers them. The answer to "why did it do that" in an unrecorded session is
honestly "there is no recording", not a reconstruction.
- **A typed session replays approximately, not exactly.** Prompts entered at a terminal were never
on the wire; orca recovers them from the harness's own transcript. Only a run started with the
prompt in argv (`orca record claude -- -p "…"`) replays byte-for-byte.
- **Some turns are not repeated.** A harness makes calls for itself — a quota probe, a
session-naming request — and a replay steps over them. Tools that need a person
(`AskUserQuestion`, plan mode) are absent when the same agent runs without one, which can make a
replayed request differ from the recorded one by enough to halt.
- **`inferred` edges are not evidence.** They are derived from a named rule at query time. Treat
them as a reading of the trace, never as something the recorder witnessed.
- **Not every harness is recordable.** Agents that read no base-URL variable and pin their own
origin need `--tls-intercept`, and some cannot be reached at all. A recording that came back
empty means the harness was not captured, not that nothing happened.
- **Replay is not a time machine, and not a sandbox.** It reproduces the agent's side of the run
against today's world. External state the run depended on — a database row, a remote branch, the
clock — is whatever it is now, and the run's own shell commands reach it for real.
- **A matching replay is not a determinism result.** The model is not re-asked; its recorded
responses are served back. Whether a fresh run would fail the same way is a different question
that replay cannot answer.
## Tools
| tool | arguments | notes |
|---|---|---|
| `orca_list_runs` | — | newest first, names the parent of each fork |
| `orca_show_run` | `run` | the full timeline |
| `orca_checkpoints` | `run` | where a fork can start |
| `orca_graph` | `run`, `to` | causal edges; `to` narrows to one chain |
| `orca_replay` | `run`, `worktree` | offline, free, repeatable |
| `orca_compare` | `run`, `models`*, `from`, `verify` | **spends real tokens** |
`run` accepts a run id or `"last"`, and defaults to `"last"`. Replay traces are skipped when
resolving `"last"`, so it means the newest run you actually recorded.
