Fix Bug

Default Flow Position

Four canonical phases, 1:1 mapping: Reproduce → framing, Trace → plan, Fix → implement, Verify → verify. The names are pinned by target-operating-model.md — do not rename or add phases; the Bug Fix Report is an output section and Commit is an opt-in post-step
approach options upstream conditional — required if Trace reveals multiple layer-fix candidates or a missing architectural pattern
Routes after: self-review (/review-architecture if layer changes; /security-review if security-relevant) → completion gate (/review-pr)
[hotfix] / [긴급] is the natural escape for time-critical fixes; verify still mandatory. [trivial] / [자명] is not appropriate for a behaviour bug — a regression test is required
Recursion guard: do not invoke $fix-bug recursively, and do not invoke $plan-feature for the bug's own framing/plan. Not an ADR 050 exemption — if the fix needs a capability the repo does not have, stop, report the gap, and route to $plan-feature

Scope Boundary

Emits Outcome (fixed / partial / not-a-bug / cannot-reproduce), never Verdict — that vocabulary belongs to review-protocol.md §4 and its three review-skill consumers
Writes update_goal_scope_plan(...) only; never sets workflow.stage (owned by $plan-feature → $execute-plan)
Decides which tests are owed; test shape comes from test-patterns.md / $test-domain
The Bug Fix Report does not replace self-review or $review-pr

Procedure

Reproduce — triage the report (observed / inferred / second-hand), record Reported As vs Observed plus the six Reproduction Evidence fields (command, expected vs actual, environment + config, prerequisite state, isolation mode, repeat count), then branch before writing any test. A confirmed failure — and only a confirmed failure — obliges a reproduction test that is red for the claimed reason (assert the specific failure mode; mandatory, not best-effort). Exit not-a-bug when a contract says the behaviour is intended or the reported causal claim is disproved in the same environment and code path; exit cannot-reproduce for anything weaker, listing the evidence still needed. Both exits write neither production code nor a test and never lead to a speculative fix; a disproved report's real finding goes to Drift Candidates.
Trace — identify the actual execution path before assuming one (HTTP CRUD, worker/scheduler, admin page, provider Selector, harness hook, or boot/config — most contain no router), record symptom site / propagation path / root cause separately, inspect conversion boundaries and DI wiring, then build and close the Cause Impact Matrix: candidate → reachability evidence → disposition (test added / already covered / not reached / deferred). Search other branches, other Protocol implementations, config Selectors, registration sets that must be complete (Base.metadata, __all__, registries), and the dialect / realm / harness-copy / app-process axes. already covered requires a test that actually runs; a reachable-but-uncovered candidate is deferred with a cited accepted limit, or it stays open and the Outcome is partial.
Fix — at the earliest boundary that owns the broken invariant (AGENTS.md § Responsibility Matrix); provider SDK calls, SDK exception translation and DI stay in infrastructure. No new patterns; answer why the existing tests missed it.
Verify — reproduction test green, focused tests, uv run pyright, pre-commit; record deferred evidence for any gate that could not run.
Bug Fix Report — always emitted, including on both Phase 1 exits.
Commit (opt-in) — if the user wants one, propose a fix: message after verification.

Read AGENTS.md and docs/ai/shared/skills/fix-bug.md for the full procedure, the six evidence fields, the matrix search procedure and termination condition, and the report template.

Small bugs use the documented Small-Bug Lane in the shared procedure rather than an exception token. It keeps all four phases, the existence gate, red/green, one focused test (the Phase 1 reproduction test kept as the regression test), pyright + pre-commit, self-review and $review-pr, and it must be declared as Lane: small-bug in the report; it drops the multi-row matrix, the unit-test-at-cause layer, the risk-based gate sweep, the architecture/security review routing, and the report fields that are empty by eligibility. The shared body carries the full delta table.

# Fix Bug

## Default Flow Position
- Four canonical phases, 1:1 mapping: Reproduce → `framing`, Trace → `plan`, Fix → `implement`,
Verify → `verify`. The names are pinned by `target-operating-model.md` — do not rename or add
phases; the Bug Fix Report is an output section and Commit is an opt-in post-step
- `approach options` upstream conditional — required if Trace reveals multiple layer-fix candidates
or a missing architectural pattern
- Routes after: self-review (`/review-architecture` if layer changes; `/security-review` if
security-relevant) → completion gate (`/review-pr`)
- `[hotfix]` / `[긴급]` is the natural escape for time-critical fixes; verify still mandatory.
`[trivial]` / `[자명]` is **not** appropriate for a behaviour bug — a regression test is required
- Recursion guard: do not invoke `$fix-bug` recursively, and do not invoke `$plan-feature` for the
bug's own framing/plan. **Not an ADR 050 exemption** — if the fix needs a capability the repo
does not have, stop, report the gap, and route to `$plan-feature`

## Scope Boundary
- Emits **`Outcome`** (`fixed` / `partial` / `not-a-bug` / `cannot-reproduce`), never `Verdict` —
that vocabulary belongs to `review-protocol.md` §4 and its three review-skill consumers
- Writes `update_goal_scope_plan(...)` only; **never** sets `workflow.stage` (owned by
`$plan-feature` → `$execute-plan`)
- Decides *which* tests are owed; test shape comes from `test-patterns.md` / `$test-domain`
- The Bug Fix Report does not replace self-review or `$review-pr`

## Procedure

1. **Reproduce** — triage the report (`observed` / `inferred` / `second-hand`), record `Reported As`
vs `Observed` plus the six `Reproduction Evidence` fields (command, expected vs actual,
environment + config, prerequisite state, isolation mode, repeat count), then **branch before
writing any test**. A confirmed failure — and only a confirmed failure — obliges a reproduction
test that is red **for the claimed reason** (assert the specific failure mode; mandatory, not
best-effort). Exit `not-a-bug` when a contract says the behaviour is intended or the reported
causal claim is disproved in the same environment and code path; exit `cannot-reproduce` for
anything weaker, listing the evidence still needed. Both exits write neither production code nor
a test and never lead to a speculative fix; a disproved report's real finding goes to
`Drift Candidates`.
2. **Trace** — identify the actual execution path before assuming one (HTTP CRUD, worker/scheduler,
admin page, provider Selector, harness hook, or boot/config — most contain no router), record
symptom site / propagation path / root cause separately, inspect conversion boundaries and DI
wiring, then build and close the **Cause Impact Matrix**: candidate → reachability evidence →
disposition (`test added` / `already covered` / `not reached` / `deferred`). Search other
branches, other Protocol implementations, config Selectors, **registration sets** that must be
complete (`Base.metadata`, `__all__`, registries), and the dialect / realm / harness-copy /
app-process axes. `already covered` requires a test that actually runs; a reachable-but-uncovered
candidate is `deferred` with a cited accepted limit, or it stays open and the `Outcome` is
`partial`.
3. **Fix** — at the earliest boundary that **owns** the broken invariant (`AGENTS.md`
§ Responsibility Matrix); provider SDK calls, SDK exception translation and DI stay in
infrastructure. No new patterns; answer why the existing tests missed it.
4. **Verify** — reproduction test green, focused tests, `uv run pyright`, `pre-commit`; record
deferred evidence for any gate that could not run.
5. **Bug Fix Report** — always emitted, including on both Phase 1 exits.
6. **Commit** (opt-in) — if the user wants one, propose a `fix:` message after verification.

Read `AGENTS.md` and `docs/ai/shared/skills/fix-bug.md` for the full procedure, the six evidence
fields, the matrix search procedure and termination condition, and the report template.

Small bugs use the documented Small-Bug Lane in the shared procedure rather than an exception
token. It keeps all four phases, the existence gate, red/green, one focused test (the Phase 1 reproduction test kept as the regression test),
pyright + pre-commit, self-review and `$review-pr`, and it must be **declared** as `Lane: small-bug` in the report; it drops the multi-row matrix, the
unit-test-at-cause layer, the risk-based gate sweep, the architecture/security review routing, and
the report fields that are empty by eligibility. The shared body carries the full delta table.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.

Fix Bug

Default Flow Position

Four canonical phases, 1:1 mapping: Reproduce → framing, Trace → plan, Fix → implement, Verify → verify. The names are pinned by target-operating-model.md — do not rename or add phases; the Bug Fix Report is an output section and Commit is an opt-in post-step
approach options upstream conditional — required if Trace reveals multiple layer-fix candidates or a missing architectural pattern
Routes after: self-review (/review-architecture if layer changes; /security-review if security-relevant) → completion gate (/review-pr)
[hotfix] / [긴급] is the natural escape for time-critical fixes; verify still mandatory. [trivial] / [자명] is not appropriate for a behaviour bug — a regression test is required
Recursion guard: do not invoke $fix-bug recursively, and do not invoke $plan-feature for the bug's own framing/plan. Not an ADR 050 exemption — if the fix needs a capability the repo does not have, stop, report the gap, and route to $plan-feature

Scope Boundary

Emits Outcome (fixed / partial / not-a-bug / cannot-reproduce), never Verdict — that vocabulary belongs to review-protocol.md §4 and its three review-skill consumers
Writes update_goal_scope_plan(...) only; never sets workflow.stage (owned by $plan-feature → $execute-plan)
Decides which tests are owed; test shape comes from test-patterns.md / $test-domain
The Bug Fix Report does not replace self-review or $review-pr

Procedure

Reproduce — triage the report (observed / inferred / second-hand), record Reported As vs Observed plus the six Reproduction Evidence fields (command, expected vs actual, environment + config, prerequisite state, isolation mode, repeat count), then branch before writing any test. A confirmed failure — and only a confirmed failure — obliges a reproduction test that is red for the claimed reason (assert the specific failure mode; mandatory, not best-effort). Exit not-a-bug when a contract says the behaviour is intended or the reported causal claim is disproved in the same environment and code path; exit cannot-reproduce for anything weaker, listing the evidence still needed. Both exits write neither production code nor a test and never lead to a speculative fix; a disproved report's real finding goes to Drift Candidates.
Trace — identify the actual execution path before assuming one (HTTP CRUD, worker/scheduler, admin page, provider Selector, harness hook, or boot/config — most contain no router), record symptom site / propagation path / root cause separately, inspect conversion boundaries and DI wiring, then build and close the Cause Impact Matrix: candidate → reachability evidence → disposition (test added / already covered / not reached / deferred). Search other branches, other Protocol implementations, config Selectors, registration sets that must be complete (Base.metadata, __all__, registries), and the dialect / realm / harness-copy / app-process axes. already covered requires a test that actually runs; a reachable-but-uncovered candidate is deferred with a cited accepted limit, or it stays open and the Outcome is partial.
Fix — at the earliest boundary that owns the broken invariant (AGENTS.md § Responsibility Matrix); provider SDK calls, SDK exception translation and DI stay in infrastructure. No new patterns; answer why the existing tests missed it.
Verify — reproduction test green, focused tests, uv run pyright, pre-commit; record deferred evidence for any gate that could not run.
Bug Fix Report — always emitted, including on both Phase 1 exits.
Commit (opt-in) — if the user wants one, propose a fix: message after verification.

Read AGENTS.md and docs/ai/shared/skills/fix-bug.md for the full procedure, the six evidence fields, the matrix search procedure and termination condition, and the report template.

# Fix Bug

## Procedure

Read `AGENTS.md` and `docs/ai/shared/skills/fix-bug.md` for the full procedure, the six evidence
fields, the matrix search procedure and termination condition, and the report template.

Small bugs use the documented Small-Bug Lane in the shared procedure rather than an exception
token. It keeps all four phases, the existence gate, red/green, one focused test (the Phase 1 reproduction test kept as the regression test),
pyright + pre-commit, self-review and `$review-pr`, and it must be **declared** as `Lane: small-bug` in the report; it drops the multi-row matrix, the
unit-test-at-cause layer, the risk-based gate sweep, the architecture/security review routing, and
the report fields that are empty by eligibility. The shared body carries the full delta table.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
