 ## PR Comment (mandatory)

+# ADR-019: Deterministic review posting tools (post-review, post-docs-review)
+
+## Статус
+Accepted (2026-07-24)
+
+## Контекст
+
+Reviewer и docs-reviewer агенты постят verdict-комментарии на PR через raw `gh pr comment` с ручным форматированием heading + verdict line:
+
+- reviewer: `## Code Review Summary` + `### Verdict: APPROVE|REQUEST_CHANGES|NEEDS_DISCUSSION`
+- docs-reviewer: `## Docs Review Summary` + `### Verdict: APPROVE|FIXED|NO_CHANGES`
+
+`pipeline-status.py` парсит эти комментарии regex'ами для определения статуса фаз REVIEW и DOCS:
+- `REVIEW_VERDICT_RE = re.compile(r"## Code Review Summary.*?###\s*Verdict:\s*(\w+)", re.IGNORECASE | re.DOTALL)`
+- `DOCS_REVIEW_RE = re.compile(r"Docs Review", re.IGNORECASE)` — substring match
+
+Риски текущего подхода (raw `gh pr comment`):
+1. **Wrong heading** — reviewer случайно пишет `## Code Review` (без "Summary") или `## Review Summary` → `REVIEW_VERDICT_RE` не матчит → pipeline NOT_DONE (блокировка)
+2. **Verdict typo** — `APROVE` вместо `APPROVE`, `REQUEST_CHANGES` с пробелом → regex не матчит verdict → NOT_DONE
+3. **No mutual exclusion** — любой агент может постить `## Code Review Summary` (нет guard "только reviewer")
+4. **False positive** — `DOCS_REVIEW_RE` substring match `Docs Review` (без `## ` prefix требования), теоретический false positive если любой комментарий упомянет "Docs Review" в тексте
+
+Root cause: формат комментария контролируется промптом (soft guard), не type system. Модель может опечататься, забыть heading, изменить формат.
+
+## Решение
+
+Детерминированные TS tools, которые гарантируют heading + verdict формат через type system:
+
+### 1. `post-review.ts` tool (`.opencode/tools/post-review.ts`)
+
+- Args: `pr_number: number`, `verdict: enum(APPROVE, REQUEST_CHANGES, NEEDS_DISCUSSION)`, `body: string`
+- Генерирует comment: `## Code Review Summary\n\n${body}\n\n### Verdict: ${verdict}`
+- Вызывает `gh pr comment N --body <comment> --repo slaid098/opencode-config` через spawnSync
+- Body — содержимое БЕЗ heading и verdict (tool добавляет их сам)
+- Verdict enum (zod) гарантирует: только APPROVE/REQUEST_CHANGES/NEEDS_DISCUSSION, опечатки отклоняются на schema layer
+
+### 2. `post-docs-review.ts` tool (`.opencode/tools/post-docs-review.ts`)
+
+- Args: `pr_number: number`, `verdict: enum(APPROVE, FIXED, NO_CHANGES)`, `body: string`
+- Генерирует comment: `## Docs Review Summary\n\n${body}\n\n### Verdict: ${verdict}`
+- Вызывает `gh pr comment N --body <comment> --repo slaid098/opencode-config` через spawnSync
+
+### 3. Agent integration
+
+- `reviewer.md` — секция "Output Format" переписана: `gh pr comment` → `post_review({ pr_number, verdict, body })`. 3 сценария (APPROVE/REQUEST_CHANGES/NEEDS_DISCUSSION). Rules 7/8 обновлены.
+- `docs-reviewer.md` — секция "PR Comment (mandatory)" переписана: `gh pr comment` → `post_docs_review({ pr_number, verdict, body })`.
+
+### 4. Role-based access (agent.tools map)
+
+`.opencode/opencode.json` `agent.tools` map расширен:
+
+| Agent | post_review | post_docs_review |
+|---|---|---|
+| general | false | false |
+| reviewer | true | false |
+| docs-reviewer | false | true |
+| memory-syncer | false | false |
+
+Mutual exclusion: только reviewer может постить code review, только docs-reviewer — docs review. General и memory-syncer не могут постить reviews. Это устраняет риск "любой агент постит review comment".
+
+### 5. pipeline-status.py совместимость
+
+Regex'ы НЕ изменены. Tools генерируют ровно тот формат, который regex ожидает:
+- `## Code Review Summary` (exact heading) + `### Verdict: <verdict>` → `REVIEW_VERDICT_RE` матчит
+- `## Docs Review Summary` (contains `Docs Review`) → `DOCS_REVIEW_RE` матчит
+
+### 6. Тестовая инфраструктура
+
+`tests/_ts_loader.mjs` расширен:
+- zodShim: добавлен `enum: () => chain()` метод (для `tool.schema.enum(VERDICTS)`)
+- `stripTs`: strip `as const` assertions + strip `type <Name> = ...` type alias declarations (TS-only синтаксис новых tools)
+
+24 новых Python теста (12 на tool) + 14 TS тестов (документационные).
+
+## Альтернативы
+
+- **Оставить raw `gh pr comment` + усилить промпт** — отклонено: промпт = soft guard, модель (GLM) игнорирует правила форматирования. Root cause (формат контролируется промптом, не type system) не устранён. Документировано в PR#85 (docs-reviewer marker) — промпт-правила ненадёжны.
+
+- **Validate comment format post-hoc в pipeline-status.py** — отклонено: pipeline-status.py уже парсит regex'ами, но это detection, не prevention. Comment уже постит с wrong heading → pipeline NOT_DONE → нужно перезапустить reviewer. Tool предотвращает ошибку на этапе создания (prevention > detection).
+
+- **Параметризовать `--repo` через `git remote` (как ADR-007 для pipeline-status.py)** — отклонено: out of scope. `merge-pr.ts` тоже хардкодит `--squash --delete-branch` (не параметризует repo). Для других репо — отдельный PR (параметризация всех tools). Сейчас tools специфичны для `slaid098/opencode-config`.
+
+- **Запретить raw `gh pr comment` в allow-list (принудить к tool)** — отклонено: оставлено для обратной совместимости (fallback). Tools используют spawnSync напрямую (не через bash permission layer), так что raw `gh pr comment*` в allow-list не конфликтует. Если захотеть strict tool-only — отдельный PR с deny правилом `gh pr comment*`.
+
+- **Расширить `DOCS_REVIEW_RE` до `## Docs Review Summary` (exact heading)** — отклонено: risk of breaking existing comments. Tools уже генерируют exact heading, но старые comments (до этого PR) могут иметь другой формат. Substring match остаётся как tolerant fallback. Future PR может tighten regex после migration.

Вызывает `gh pr comment N --body <comment> --repo slaid098/opencode-config` через spawnSync. Verdict enum: `APPROVE`, `REQUEST_CHANGES`, `NEEDS_DISCUSSION`.

Вызывает `gh pr comment N --body <comment> --repo slaid098/opencode-config` через spawnSync. Verdict enum: `APPROVE`, `FIXED`, `NO_CHANGES`.
+- `.opencode/agents/reviewer.md` — секция "Output Format" переписана: `gh pr comment` → `post_review({ pr_number, verdict, body })`. Tool auto-generates heading + verdict line, body — содержимое между ними. 3 сценария (APPROVE/REQUEST_CHANGES/NEEDS_DISCUSSION). Frontmatter description + Rules 7/8 обновлены.
+- `.opencode/agents/docs-reviewer.md` — секция "PR Comment (mandatory)" переписана: `gh pr comment` → `post_docs_review({ pr_number, verdict, body })`. Frontmatter description обновлён.
+- `.opencode/opencode.json` — `agent.tools` map расширен: `post_review` + `post_docs_review` добавлены для 4 агентов (general/reviewer/docs-reviewer/memory-syncer). reviewer: post_review=true, post_docs_review=false; docs-reviewer: post_review=false, post_docs_review=true; general+memory-syncer: оба false.
+- `tests/_ts_loader.mjs` — zodShim расширен методом `enum: () => chain()` (для `tool.schema.enum(VERDICTS)`). `stripTs` расширен: strip `as const` assertions + strip `type <Name> = ...` type alias declarations (TS-only синтаксис, используется в новых tools).
+- `tests/test_post_review_tool.ts` — 7 TS тестов (документационные): valid APPROVE/REQUEST_CHANGES/NEEDS_DISCUSSION, invalid verdict, heading, verdict line, spawnSync args.
+- `tests/test_post_docs_review_tool.ts` — 7 TS тестов: valid APPROVE/FIXED/NO_CHANGES, invalid verdict, heading, verdict line, spawnSync args.
+- `tests/test_post_review_tool.py` — 12 Python тестов через `_ts_loader.mjs` (exec_stub_json): load, 3 valid verdicts, invalid verdict (permissive — zod validates, not execute), heading, 3 verdict lines, spawnSync args, cwd propagation, gh failure.
+- `tests/test_post_docs_review_tool.py` — 12 Python тестов: load, 3 valid verdicts, invalid verdict, heading, 3 verdict lines, spawnSync args, cwd propagation, gh failure.
+- `docs/project-map/README.md` — обновлён: новые tools (post-review.ts, post-docs-review.ts), новые тесты, обновлённые описания agents (reviewer/docs-reviewer используют post_review/post_docs_review tools).
+- ADR-019 + этот handoff
+
+## Почему
+Reviewer и docs-reviewer постят комментарии через raw `gh pr comment` с ручным форматированием heading + verdict. `pipeline-status.py` парсит эти комментарии regex'ами (`REVIEW_VERDICT_RE = re.compile(r"## Code Review Summary.*?###\s*Verdict:\s*(\w+)")`, `DOCS_REVIEW_RE = re.compile(r"Docs Review")`). Риски:
+1. Reviewer случайно использует wrong heading → pipeline NOT_DONE (блокировка)
+2. Verdict опечатан (например `APROVE` вместо `APPROVE`) → regex не матчит → NOT_DONE
+3. Нет mutual exclusion между review и docs-review комментариями
+4. `DOCS_REVIEW_RE` — substring match, теоретический false positive если любой комментарий упомянет "Docs Review"
+
+Решение: детерминированные TS tools, которые гарантируют heading + verdict формат через type system (zod enum). Tool принимает body БЕЗ heading — heading auto-generated. Это устраняет root cause ошибок форматирования: агент не может опечататься в heading или verdict, т.к. они генерируются кодом, не промптом.
+
+Паттерн `merge-pr.ts` (PR#30, ADR-010): thin TS wrapper → spawnSync → `context.worktree` как cwd. Tools auto-discovered через `@opencode-ai/plugin`. agent.tools map в opencode.json контролирует role-based access (reviewer → post_review, docs-reviewer → post_docs_review, general+memory-syncer → none).
+
+## Pending
+- Skills/AGENTS.md правила форматов reviews теперь дублируются (agents текст + tools код). Future PR может заменить agents rules на "use post_review/post_docs_review tools" references.
+- `gh pr comment*` permission в reviewer.md/docs-reviewer.md frontmatter оставлен — tools вызывают spawnSync напрямую (не через bash permission layer). Если захотеть запретить raw `gh pr comment` (принудить к tool) — добавить deny правило. Сейчас оба пути работают.
+- pipeline-status.py regex'ы НЕ изменены (tools совместимы с существующим парсингом — генерируют ровно тот формат, который regex ожидает).
+
+## Watch out
+- `_ts_loader.mjs` zodShim НЕ валидирует enum (chainable builder без checks) — enum validation происходит в opencode runtime (zod), НЕ внутри execute(). Тест `test_invalid_verdict_not_validated_by_execute` документирует: execute() permissive, guard в zod schema. Это intentional — не дублировать валидацию в execute().
+- `_ts_loader.mjs` `stripTs` расширен для `as const` и `type <Name> = ...` — TS-only синтаксис, которого не было в предыдущих tools (commit/create-pr/create-issue/merge-pr не используют type aliases). Если будущие tools добавят другие TS-only конструкции (interface, generic, etc.) — stripTs нужно будет расширить дальше.
+- `post-review.ts` / `post-docs-review.ts` хардкодят `--repo slaid098/opencode-config` (как `merge-pr.ts` хардкодил `--squash --delete-branch`). Для других репо tools нужно параметризовать или создать копии. Альтернатива (через `git remote`) — out of scope этого PR (см. ADR-007 для паттерна параметризации).
+- `gh pr comment*` в allow-list reviewer.md/docs-reviewer.md остался — tools используют spawnSync (не bash permission layer), так что raw `gh pr comment` всё ещё доступен агенту. Это intentional для обратной совместимости (fallback). Запретить raw можно отдельным PR если захотеть strict tool-only.
+- ADR number = sequential (019), НЕ PR number. Эволюция известного паттерна (PR#26 docs-reviewer typo — записал PR number как ADR number).
+- TS-тесты (`test_*.ts`) — документационные, CI гоняет Python-версии через `_ts_loader.mjs` (bun нет на runner).
+- 347 тестов всего (323 существующих + 24 новых), все green. ruff check passes.

+"""Tests for .opencode/tools/post-docs-review.ts — the post-docs-review custom tool.
+
+Mirrors tests/test_commit_tool.py / test_create_pr_tool.py:
+exercises the tool's ``execute()`` function via ``tests/_ts_loader.mjs``
+using the ``exec_stub_json`` mode (multi-arg tools).
+
+The loader is parameterized via the ``TS_FILE`` env var. These tests set
+``TS_FILE=.opencode/tools/post-docs-review.ts``.
+
+Modes used:
+- ``load`` — sanity-check that the tool loads and declares pr_number, verdict,
+  body args.
+- ``exec_stub_json`` — call execute with a stubbed spawnSync to verify:
+  (a) success path: valid verdict (APPROVE/FIXED/NO_CHANGES)
+      → "Docs review posted on PR #N: verdict=<V>",
+  (b) comment heading: body passed to gh contains "## Docs Review Summary",
+  (c) comment verdict: body passed to gh contains "### Verdict: <V>",
+  (d) spawnSync args: gh pr comment N --body <comment> --repo slaid098/opencode-config.
+
+post-docs-review.ts makes 1 spawnSync call (gh pr comment) on all paths.
+
+Note on enum validation: see test_post_review_tool.py — same delegation to
+zod schema, execute() itself is permissive.

+/**
+ * Tests for .opencode/tools/post-docs-review.ts — the post-docs-review custom tool.
+ *
+ * Mirror of tests/test_post_review_tool.ts / test_commit_tool.ts:
+ * the tool is a spawnSync wrapper around `gh pr comment` with verdict enum
+ * validation and deterministic comment heading generation.
+ *
+ * Runtime note: opencode ships a standalone binary with Bun bundled inside;
+ * there is no separate `bun` CLI on the host (CI runner uses node + pytest).
+ * The CI runs the equivalent Python tests in tests/test_post_docs_review_tool.py
+ * via the JS loader tests/_ts_loader.mjs (exec_stub_json mode for multi-arg
+ * tools). This file documents the intended TS-side test cases and is
+ * runnable under `bun test` once a bun runtime is available on the host.
+ *
+ * Test cases (mirror tests/test_post_docs_review_tool.py):
+ *   - test_valid_approve — valid APPROVE verdict → "Docs review posted"
+ *   - test_valid_fixed — valid FIXED verdict → "Docs review posted"
+ *   - test_valid_no_changes — valid NO_CHANGES verdict → "Docs review posted"
+ *   - test_invalid_verdict — invalid verdict "APROVE" (typo) → error
+ *   - test_comment_has_heading — comment body contains "## Docs Review Summary"
+ *   - test_comment_has_verdict — comment body contains "### Verdict: <verdict>"
+ *   - test_spawnsync_args — spawnSync called with correct gh args

+"""Tests for .opencode/tools/post-review.ts — the post-review custom tool.
+
+Mirrors tests/test_commit_tool.py / test_create_pr_tool.py:
+exercises the tool's ``execute()`` function via ``tests/_ts_loader.mjs``
+using the ``exec_stub_json`` mode (multi-arg tools).
+
+The loader is parameterized via the ``TS_FILE`` env var. These tests set
+``TS_FILE=.opencode/tools/post-review.ts``.
+
+Modes used:
+- ``load`` — sanity-check that the tool loads and declares pr_number, verdict,
+  body args.
+- ``exec_stub_json`` — call execute with a stubbed spawnSync to verify:
+  (a) success path: valid verdict (APPROVE/REQUEST_CHANGES/NEEDS_DISCUSSION)
+      → "Review posted on PR #N: verdict=<V>",
+  (b) comment heading: body passed to gh contains "## Code Review Summary",
+  (c) comment verdict: body passed to gh contains "### Verdict: <V>",
+  (d) spawnSync args: gh pr comment N --body <comment> --repo slaid098/opencode-config.
+
+post-review.ts makes 1 spawnSync call (gh pr comment) on all paths.
+
+Note on enum validation: the zod enum (tool.schema.enum(VERDICTS)) validates
+verdicts at the opencode layer. The _ts_loader.mjs shim does NOT validate
+(it returns a chainable builder without checks). Therefore the "invalid
+verdict" test documents that execute() itself does not validate — the guard
+is the zod schema in the real opencode runtime. The test passes a bad verdict
+and verifies the tool still builds the comment (no inline validation).

+/**
+ * Tests for .opencode/tools/post-review.ts — the post-review custom tool.
+ *
+ * Mirror of tests/test_commit_tool.ts / test_create_pr_tool.ts:
+ * the tool is a spawnSync wrapper around `gh pr comment` with verdict enum
+ * validation and deterministic comment heading generation.
+ *
+ * Runtime note: opencode ships a standalone binary with Bun bundled inside;
+ * there is no separate `bun` CLI on the host (CI runner uses node + pytest).
+ * The CI runs the equivalent Python tests in tests/test_post_review_tool.py
+ * via the JS loader tests/_ts_loader.mjs (exec_stub_json mode for multi-arg
+ * tools). This file documents the intended TS-side test cases and is
+ * runnable under `bun test` once a bun runtime is available on the host.
+ *
+ * Test cases (mirror tests/test_post_review_tool.py):
+ *   - test_valid_approve — valid APPROVE verdict → "Review posted"
+ *   - test_valid_request_changes — valid REQUEST_CHANGES verdict → "Review posted"
+ *   - test_valid_needs_discussion — valid NEEDS_DISCUSSION verdict → "Review posted"
+ *   - test_invalid_verdict — invalid verdict "APROVE" (typo) → error
+ *   - test_comment_has_heading — comment body contains "## Code Review Summary"
+ *   - test_comment_has_verdict — comment body contains "### Verdict: <verdict>"
+ *   - test_spawnsync_args — spawnSync called with correct gh args
