A run parked in one long agent stage reported 2m 8s of active time against 16m 53s of wall clock — the two finished stages — while the running stage had been doing continuous inference and tool work for over 14 minutes. `live_run_timing` summed `filter_map(|stage| stage.timing)`, and `stage.timing` is only written at finalization. Wall time ticked live off `start_time`; active time did not tick at all. Stage projections now accumulate brackets from the event log: - Closing an inference bracket folds its span into `live_inference_ms` instead of discarding it, including across retries, matching the in-process stopwatch. - Tool calls open a batch on the first outstanding call and close it when the last one drains, so tools running concurrently within a turn count once — the same span `execute_tool_calls` is bracketed by. Summing per-call durations would over-count parallel tool use. Subagent tool events are excluded; they run inside the root call's span already. - `StageProjection::live_timing(now)` composes accumulators with any open bracket, per handler: agent stages use the brackets, prompt and command stages count elapsed time as inference and tool respectively, and handlers that wait on a human, timer, condition, or child branches report zero. Active is clamped to wall per stage. A worker killed mid-turn leaves its bracket open forever, and without the clamp it would tick up unbounded. The clamp does not need to detect the dead worker: a stage cannot have been active longer than it has existed. `watchdog.timeout` remains the authority on whether a run is stuck. The clamp is deliberately not applied at run level, where concurrent branches can legitimately sum past run wall time. Timing is derived from events rather than emitted by the worker, so this needs no event-schema change and applies to runs already stored. `StageProjection.timing` keeps its terminal-only meaning, and the authoritative breakdown still replaces the live estimate at terminal events. The billing endpoint had the same hole behind its `wall_only` fallback: running stages reported zero inference/tool/active. Not visible in the product, which renders only `wall_time_ms`, but wrong for any other consumer of `GET /runs/{id}/billing`. Parallel branch stages lose their breakdown permanently, even after completion, because `parallel.branch.completed` carries only `duration_ms`. That is a separate data-loss bug, tracked in #644.

Fixes: - Background-agent output was run through skill expansion. A child that wrote a bare path ("cleaned up /tmp") failed the whole parent turn with `Unknown skill: /tmp`, and a child whose output happened to name a real skill had its report replaced by that skill's template. Synthesized harness turns now skip expansion; only text the user typed can invoke a skill. - `begin_shutdown` suppressed the pending notification before deciding whether a shutdown would happen. Stopping an agent that had just finished rejected the stop *and* discarded the result the parent was owed. Suppression now happens only once shutdown is committed. - `spawn_inner` registered the notification after publishing the agent in `state.agents`, so a concurrent `shutdown_all` in that window left a pending entry the monitor never completes, and the parent's drain loop would never see the queue as drained. Registration now precedes publication. - `TaskOutput.timeout` was declared `number` but parsed with `as_u64`, so a schema-valid `30000.0` failed at runtime. - Update the fabro-server alias test for the `sonnet` alias moving to Claude Sonnet 5. Cleanups: - The supervisor renders the notification turn; `Session` no longer knows the envelope format. - Replace six near-identical prompt snapshots with a property test over all eight conditional combinations, keeping the default and all-conditionals snapshots for wording. - Collapse `TodoRuntime`'s two mutexes into one. - Read the prompt vocabulary from the registry instead of hardcoding it. - Drop internal vocabulary from the `SendMessage` tool description.

Add comments only for constraints or reasoning the code cannot make evident. -- Validate at real boundaries such as external input and APIs; do not add defensive branches for states excluded by established invariants. -- Run the most targeted useful verification first, then broaden it when the risk warrants it. Exercise user-facing behavior when the environment supports doing so. - -# Tool use - -Use `Read`, `Edit`, and `Write` instead of shell commands for file inspection and mutation. `Read` handles UTF-8 text and returns numbered lines; it does not render images, PDFs, or notebooks. - -Use `Bash` for searches, git inspection, builds, tests, package managers, and other terminal operations. Prefer `rg` for content search and `rg --files` with `-g` filters for file discovery. Narrow commands so their output remains useful. - -Each `Bash` call is a fresh foreground, non-login shell. Working-directory and environment changes do not persist between calls; keep dependent `cd` or environment setup in the same command. `timeout` is measured in milliseconds. - -Use `TaskCreate`, `TaskUpdate`, `TaskGet`, and `TaskList` when meaningful multi-step work benefits from visible tracking. Keep statuses current as work progresses. Skip task tracking when it adds no value. - -Use `WebFetch` with both a URL and a prompt describing the information to extract. - -Use `WebSearch` when current external information is needed. Its input is a search query; use `WebFetch` to inspect a specific result. - - -Other registered tools may be supplied by MCP servers or the surrounding Fabro workflow. Follow their definitions. - - - - - -# Communicating with the user - -Before the first tool call, state what you are about to do in one concise sentence. While working, give brief updates only at meaningful milestones, such as finding the cause, changing direction, or completing a major phase. - -Do not expose internal deliberation. Write for a teammate catching up: use complete sentences, explain only details that affect conclusions or next actions, and avoid private shorthand. - -Lead the final response with the outcome. A simple question deserves a direct answer rather than unnecessary sections. Be concise by omitting low-value detail, not by compressing useful explanation into fragments. - -# Context management - -Long sessions may be summarized and continued in a new context window. Treat the supplied summary as the continuation of the same work. Do not wrap up early merely because the session is long. diff --git a/lib/components/fabro-agent/src/session.rs b/lib/components/fabro-agent/src/session.rs index f04e99257..c72d33683 100644 --- a/lib/components/fabro-agent/src/session.rs +++ b/lib/components/fabro-agent/src/session.rs @@ -47,10 +47,7 @@ use crate::skills::{ ExpandedInput, Skill, default_skill_dirs, discover_skills, expand_skill, make_use_skill_tool_for_vocabulary, }; -use crate::subagent::{ - SubAgentCallbackEvent, SubAgentEventCallback, SubAgentSupervisor, - format_parent_notification_batch, -}; +use crate::subagent::{SubAgentCallbackEvent, SubAgentEventCallback, SubAgentSupervisor}; use crate::tool_execution::execute_tool_calls; use crate::tool_permissions::canonical_tool_name; use crate::tool_registry::ToolDefinitionWithSource; @@ -371,6 +368,18 @@ struct BuiltRequest { context_window: StageContextWindowProjection, } +/// Whether an input's `/name` tokens should be treated as skill references. +/// +/// Only text the user actually typed can invoke a skill.

Two of the three bugs fixed in the previous commit were ordering bugs in the coupling between those two structures: suppress-vs-commit in `begin_shutdown`, and register-vs-publish in `spawn_inner`. Both were fixed by ordering the steps correctly. Keeping the registration beside the status it is delivered with makes that whole class unrepresentable instead: - Registration is now a field on the `SubAgent` literal `spawn_inner` already builds, under the lock that publishes it. There is no window between publishing an agent and registering its notification. - Suppression on shutdown happens inside the critical section that decides the shutdown, after the status transition commits, so a rejected shutdown cannot discard a result the parent is owed. - `next_parent_notification_batch` scans agents for a live registration whose status is `Finished`, and ignores `Closing`/`Closed` outright -- so a shutdown racing delivery can no longer park the parent on a result that will never arrive, even if suppression were missed. `spawn_result_monitor` no longer takes the hub; it bumps a single `watch` counter after committing the status it already commits. Batch order was the queue's insertion order, so `SubAgent` carries a `spawn_seq` to keep delivery oldest-first. Tests move from exercising the hub directly to the supervisor API, and cover spawn-order batching and the shutdown-races-delivery case that the old shape could not express.

Root and child therefore resolved the same `list_id` through different runtimes: both ID counters started at zero, so both emitted `todo.created` with id `1` for the same list, and `TodoListProjection::upsert` matches on id -- the child's task replaced the parent's in the persisted projection. `TaskGet` and `TaskList` read the local runtime, so neither session could see the other's tasks either. The previous commit's shared runtime fixed this for Claude 5 only, because `build()` passed dependencies positionally and adding a fourth argument would have meant touching all six call sites. It grew a second constructor for Claude 5 instead, leaving the other five on a signature that could not carry the runtime. Bundle them into `ProfileDeps` so every profile takes the same `(model, &deps)`. The duplicate constructor is gone, Anthropic shares the runtime by construction rather than by opting in, and a future dependency reaches all six profiles or none. The existing Claude 5 sharing test is generalized and now also runs for Anthropic; it fails against a per-profile runtime.

From 3c755a7d4e7244ea61ecc6bc6221543698f4424c Mon Sep 17 00:00:00 2001 From: Bryan Helmkamp Date: Sun, 26 Jul 2026 07:57:42 -0400 Subject: [PATCH 07/83] refactor(agent): give Claude 5 subagent tools fabro canonical names `NativeTool` documents itself as "an identity, not a name" whose canonical form is fabro's own vocabulary, with harness names layered on as aliases: `to_string = "read_file", serialize = "Read"`. The four Claude 5 subagent tools inverted that. `ClaudeAgent` declared `to_string = "Agent"`, making the Anthropic wire name the identity and leaving `name(ToolVocabulary::Fabro)` returning `"Agent"` -- and pairing a provider-specific variant name with a generic wire name. It also meant the `Claude5` arm listed none of them: they fell through to `canonical_name()` and were correct only by accident. Rename to `BackgroundAgent` / `AgentOutput` / `StopAgent` / `MessageAgent` with fabro canonical names, keep the harness names as `serialize` aliases so `from_any_name` still resolves them, and name them explicitly in the `Claude5` vocabulary arm. Also map `Grep`/`Glob` there: that arm describes the vocabulary rather than the profile's registry, and if either were ever registered it would otherwise reach the harness lowercased. Records why these are separate identities from `spawn_agent`/`wait`/`close_agent`/`send_input` rather than aliases of them, since the capabilities genuinely differ.

What actually distinguishes them is `build_system_prompt`, and for Claude 5, `register_subagent_tools`. Replace the copies with one `impl_base_profile_accessors!()` invocation. A macro rather than trait defaults because three implementors have no `BaseProfile` to delegate to -- `TestProfile`, the workflow crate's `ShutdownTestProfile`, and the server's `AskFabroProfile` -- so a default would need a runtime fallback for a case the compiler can already rule out. Those three keep their hand-written accessors and are untouched.

The JSON Schema already enforces that at the model boundary, so the lenient structs deserialize the strict payload unchanged. `normalize_claude5_questions` then reproduced `normalize_anthropic_questions` plus an inlined copy of `options_from_anthropic`, so `option_key`, `display_text`, and `bounded_display_field` were each applied in two places and could drift. Replace both with one normalizer taking a `QuestionLimits`. The genuine Claude 5 deltas -- at most four questions, two to four options, a twelve-character header cap, required header and option descriptions, and no previews on multi-select -- become data rather than a second code path. Two rules serde used to enforce are now the normalizer's: a missing header and a missing option description. Both are still rejected, with a clearer message than serde's "missing field". `multiSelect` now defaults to false instead of being a deserialization error; the schema still marks it required, which is where that contract belongs. Adds tests pinning the strict rules against the shared normalizer, and one asserting the lenient contract still accepts optional headers and descriptions.

A failed final push, branch check, or PR creation marks the run as failed with `publish_failed`; the terminal run event is emitted only after this step finishes.

The edge_target_exists rule only checked whether the node id was present in the graph, which was always true by then, so a misspelled endpoint became an attribute-free node that defaulted to shape=box — an LLM stage. Validation emitted a prompt_on_llm_nodes warning and exited 0. Node now carries `implicit`, set only when the parser synthesizes the node from an edge endpoint. A declaration anywhere in the workflow clears it, so order does not matter and subgraph declarations count. Node::new leaves it false, so programmatic construction and graphs deserialized from older checkpoints read as declared. edge_target_exists treats an endpoint as valid only when it exists and is declared, reporting each undeclared node once. The near-identical missing-source and missing-target branches collapse into one path. The import transform copies the flag onto spliced nodes so an edge-only node inside an imported fragment is caught too. parse_and_validate_human_gate had two edge-only nodes and now declares them; it was an instance of the bug rather than a casualty of the fix. No shipped workflow, docs example, or CLI fixture relied on the old behavior.

The actionable half of every validation failure was invisible to the person running the command. print_diagnostics now emits the fix as a dim-labelled continuation line under any diagnostic that has one, at both error and warning severity. Gating it behind --verbose would defeat the point, and printing it only for errors would read as "this warning has no fix" — the warning suggestions are useful on their own. Diagnostics that set no fix simply omit the line. The severity match moved into print_diagnostic so the fix line is appended once in the loop rather than copied into all five arms; the rest of the diff is reindentation. print_diagnostics is shared by validate, preflight, graph, exec, and dry-run, so this covers all five. Eleven inline snapshots across four files gain a fix line; every change is additive.

charset=UTF-8 Content-Transfer-Encoding: 8bit The Size column in the runs list rendered SizeChip without the billed total, so its tooltip read "Size M" while the run detail header showed "Size M · $12.34 billed". The tooltip was also unreachable: the row title link paints a `before:absolute before:inset-0` overlay across the whole row, which sat above the chip and swallowed hover. Wrapping the chip in `relative z-10` lifts it above that overlay, matching how the created-by and pull request cells already handle interactive content. Runs without terminal billing keep the plain "Size M" label, same as the header.

Seeing what a stage actually spent meant leaving for the Billing tab, which reports per node rather than per visit. The stage list had no token data to show, so add a per-visit `billing` block to `GET /runs/{id}/stages`. The Billing tab's pricing rule (a provider-reported cost wins, otherwise the server catalog prices the tokens) was private to `billing_rollup`; move it to `StageProjection::billed_usage` and drive both call sites from it so the two views cannot drift. The popover's buckets use the Billing tab's labels verbatim. It stays scoped to one visit, so a looped node's row on the Billing tab is the sum of what each of its visits shows here.
