Expose operation-specific tools for map and work-pool ledgers by Copilot · Pull Request #64813 · github/gh-aw

Copilot · 2026-10-01T17:53:39Z

Map and work-pool ledgers currently expose the low-level ledger_append format to agents. This change gives those ledgers operation-specific tools while preserving the existing safe-output ingestion path.

Tool surface: Declare map and work-pool operation tools. Hide ledger_append when only those ledger types are configured; in mixed workflows, restrict it to other ledger types.
Ingestion: Route built-in tool calls through one handler that validates the target ledger and writes ledger_append-compatible entries to safe-output logs.
Guidance: Update the ledger documentation and agent prompt to describe the tools agents can call.

For example, ledger_map_put accepts a key and value without requiring the agent to construct an operation envelope:

{"ledger": "cache", "key": "status", "value": "ready"}

@copilot ensure that this support multiple ledger with the same type. add test.

Added per-type ledger enums and required explicit selection when multiple ledgers share a type, with compiler-schema and handler-routing tests. Committed as f89f00c.

🏗️ ADR required for PR #64813

This PR appears to make an architectural decision without a matching ADR on the branch or in the PR description.

Gate result: ADR required before merge.

Evidence used

adr-prefetch-summary.json shows ADR enforcement is required because the PR adds 137 lines in default business-logic directories (>100).
The PR description states a design change: expose operation-specific tools for map and work-pool ledgers while preserving the existing ledger_append ingestion path.
The diff changes workflow/tool generation, handler routing, tests, prompt text, and ledger docs, including:
- actions/setup/js/generate_safe_outputs_tools.cjs
- actions/setup/js/safe_outputs_handlers.cjs
- actions/setup/js/safe_outputs_tools_loader.cjs
- pkg/workflow/ledger.go
- docs/src/content/docs/experimental/ledger-replay.md
No ADR reference was found in the PR body, and the branch ADRs checked do not cover this decision.

Inferred decision from the PR

Introduce dedicated safe-output tools for built-in map and work-pool ledgers.
Route those tool calls through a shared handler that validates the target ledger and translates them into ledger_append-compatible records.
Hide or restrict the generic ledger_append tool when only specialized built-in ledger types are configured.

Alternatives visible in the diff

Keep exposing only the low-level ledger_append interface to agents.
Keep ledger_append alongside specialized tools for all ledgers without restricting the generic tool surface.

Consequences visible in the diff

Positive: agent-facing ledger operations become simpler and more type-specific.
Positive: existing durable ingestion remains centralized through ledger_append-compatible entries.
Negative: tool generation/registration logic becomes more complex and configuration-sensitive.
Negative: mixed-ledger workflows now depend on careful restrictions so generic and specialized tools do not conflict.

Next action
A draft ADR has been added at docs/adr/64813-expose-operation-specific-ledger-tools.md. Please review and refine it before merge.

Blocking

The end-to-end wiring is still incomplete: the regenerated smoke workflow exposes no operation-specific ledger tools, so this PR does not actually validate the new built-in ledger API.

Details

The compiled smoke-builtin-ledgers workflow still serializes GH_AW_TOOLS_META_JSON.dynamic_tools as an empty array even though its safe-outputs config enables built-in map and work-pool ledgers. That leaves the runtime with nothing to register for ledger_map_* / ledger_work_pool_*, so a real workflow cannot exercise the API this change is supposed to introduce.

              "repo_params": {},
-              "dynamic_tools": []
+              "dynamic_tools": [


This compiled workflow still emits dynamic_tools: [], so the new ledger_map_*/ledger_work_pool_* API never reaches the runtime and the smoke test cannot exercise the feature this PR is adding.

💡 Why this blocks the change

generate_safe_outputs_tools.cjs only mounts operation-specific ledger tools when they arrive through dynamic_tools. In this regenerated lock file, the safe-outputs config includes built-in ledgers, but GH_AW_TOOLS_META_JSON still serializes an empty dynamic_tools array, so the runtime falls back to the old surface and this workflow stops validating the new built-in API end to end.

Please fix the compilation path so built-in ledger tools are emitted for real workflows, then regenerate the lock file.

Impeccable review (harden)

I verified the three existing review comments against the current diff — all are still valid and blocking:

pkg/workflow/ledger.go:569 — Confirmed by running go test ./pkg/workflow/ -run TestBuiltinLedgerDeclarations: it fails on every ledger type because the prompt wording was changed to "configured ledger safe-output tools" but the test still asserts the substring "ledger append safe output". This is a build-breaking regression, not just a comment nit.
pkg/workflow/safe_outputs_tools_generation.go:51 — Confirmed: generateDynamicTools adds ledger_map_put/ledger_work_pool_* tool names unconditionally with no check against data.SafeOutputs.Jobs, .Scripts, or .Actions keys, so a workflow with a map/work-pool ledger plus a custom job/script/action literally named e.g. ledger_map_put would silently register two tools with the same name.
pkg/workflow/ledger.go:569 (tool discoverability) — Confirmed: buildLedgerPromptSection never emits the actual tool names (ledger_map_put, ledger_work_pool_submit, etc.), so the agent has no textual guidance pointing it at the new dedicated tools; it only learns of them if the MCP tool list surfaces them separately.

No new issues found beyond what's already flagged. Please address the above before merge — #1 is a failing test on this branch.

Skills-Based Review 🧠

Applied /tdd, /codebase-design, and /grill-with-docs — requesting changes: one issue is a confirmed test failure, the others are design/documentation gaps.

📋 Key Themes & Highlights

Key Themes

Broken test (verified by running the suite): TestBuiltinLedgerDeclarations fails for every built-in ledger type because the prompt-section wording in ledger.go changed but the test assertion wasn't updated.
No reservation against name collisions: new ledger_map_put/ledger_work_pool_* tool names aren't checked against custom safe-jobs with the same name.
Agent prompt doesn't list the new tools: buildSafeOutputsSections never surfaces the dynamic ledger_* builtin names, so agents have no guidance to call them — this is the exact gap the PR description says it closes ("Guidance: ... describe the tools agents can call").

Positive Highlights

✅ Good layered test coverage across JS (generate_safe_outputs_tools, safe_outputs_handlers, safe_outputs_tools_loader) and Go (ledger_test.go, tool computation/generation).
✅ Clean routing of built-in tool calls through a single ledgerBuiltinHandler that validates operation fields before writing ledger_append-compatible entries.
✅ Sensible enum/required adjustments to the ledger property based on how many ledgers of a type are configured.

Three existing Copilot review comments on this PR already flag the same issues in more detail; I independently reproduced the test failure locally (go test ./pkg/workflow/ -run TestBuiltinLedgerDeclarations) and confirmed the prompt-building gap by reading unified_prompt_step.go.

Comments that could not be inline-anchored

pkg/workflow/ledger_test.go:85

[/tdd] TestBuiltinLedgerDeclarations asserts section.Content contains "ledger append safe output", but buildLedgerPromptSection in ledger.go was changed to emit "the configured ledger safe-output tools". This breaks the test for every built-in ledger type (log, set, map, table, counter, work-pool).

Run the suite locally — go test ./pkg/workflow/ -run TestBuiltinLedgerDeclarations fails on this repo right now. Update the asserti…

pkg/workflow/safe_outputs_tools_generation.go:51

[/codebase-design] The new tool names (ledger_map_put, ledger_work_pool_submit, etc.) are added to dynamicTools without being checked against existing custom job/dispatch/call-workflow tool names, so a workflow that happens to define a safe-job literally named ledger_map_put would register two MCP tools with the same name.

Open review signals:...

The compiled smoke metadata already contained map tools on the previous head. I added dedicated map put/delete and work-pool submit/cancel smoke calls, plus a compile-time metadata regression test for all eight tools in 43e9dfd (local checks pass). PR #64813 was merged concurrently at e255d1c, before this follow-up commit, so 43e9dfd is on the branch but may require a separate follow-up to land on main.
