+# ADR-015: Validation tools (commit, create-pr, create-issue)
+
+## Статус
+Accepted (2026-07-24)
+
+## Контекст
+AGENTS.md содержал детерминированные правила форматов для commits, PRs, issues в текстовом виде (skills `commit`/`issue`). Агент читал правила и выполнял `git commit`/`gh pr create`/`gh issue create` через raw bash. Это нарушало pure-orchestrator model (ADR-010/PR#30): main agent = plan/delegate/verify, НЕ исполняет mutations напрямую. Правила в тексте не валидировались автоматически — агент мог допустить ошибку формата, и CI/review ловил её поздно.
+
+Нужны tools, которые агент вызывает из главного чата: tool валидирует формат (regex, language, headings, length), и только при success исполняет side-effect (git commit, gh pr create, gh issue create). На error — возвращает правила + examples (recent commits), агент корректирует и повторяет.
+
+## Решение
+3 TS tool'а, паттерн `merge-pr.ts` (thin wrapper → spawnSync → `cwd: context.worktree`):
+
+1. **commit.ts** — 1 arg `message`. Валидация: single-line, regex `^(feat|fix|chore|docs|refactor|test|style|perf)\([^)]+\): .{1,72}$`, English only (`/[\u0400-\u04FF]/`), staged files exist (`git diff --cached --name-only`). На error — правила + 5 recent commits. На success — `git commit -m <msg>`, возвращает `Committed: <msg>`
+
+2. **create-pr.ts** — 3 args (`title`, `body`, `issue_number?`). Валидация: title regex (≤72), English title, body headings (`## Что сделано`, `## Почему`), body Russian (Cyrillic), `issue_number` → append `\n\nCloses #N`. На success — `gh pr create`, возвращает `PR created: <url>`
+
+3. **create-issue.ts** — 3 args (`title`, `body`, `labels?`). Валидация: title regex (≤80 для issue), English title, body headings (`## Контекст`, `## Задача`, `## Критерии приемки`), body Russian. Labels → `--label <comma-joined>`. На success — `gh issue create`, возвращает `Issue created: <url>`
+
+Tools auto-discovered через `@opencode-ai/plugin` — НЕ регистрируются в opencode.json (подтверждение паттерна PR#30/#36).
+
+`tests/_ts_loader.mjs` расширен: новый `exec_stub_json` mode для multi-arg tools (JSON args + sequential stub responses). Существующие modes не изменены — обратная совместимость сохранена.
+
+## Альтернативы
+- Validation в skills (текстовые правила, агент читает и следует) — отклонено: не enforced автоматически, агент может ошибиться, ошибки ловятся поздно (CI/review). Tools валидируют в коде — deterministic, testable
+- Single generic "git-helper" tool с mode arg — отклонено: нарушает single-responsibility, усложняет validation logic (каждый mode имеет разные rules). 3 отдельных tool'а чище
+- Validation в opencode.json permission rules — отклонено: permission rules — security guards (allow/deny bash commands), не format validators. Format validation — domain logic, принадлежит tool коду
+- Python tools вместо TS — отклонено: существующий паттерн репо — TS tools (`merge-pr.ts`, `pipeline-status.ts`, `memory-setup.ts`). Consistency важнее personal preference

+- `tests/_ts_loader.mjs` — расширен: новый mode `exec_stub_json` для multi-arg tools (JSON args + sequential stub responses). `buildExecArgsFromJson` + `buildStubSequencer` helper functions. Существующие `load`/`exec_stub`/`exec_real` modes не изменены
+- `tests/test_commit_tool.ts` — 7 TS тестов (документационные, паттерн `test_pipeline_status_tool.ts`): valid, no scope, Cyrillic, multiline, >72, no staged, wrong type
+- `tests/test_create_pr_tool.ts` — 6 TS тестов: valid, missing scope, missing headings, Latin-only, issue linkage
+- `tests/test_create_issue_tool.ts` — 7 TS тестов: valid, >80, missing sections, Latin-only, labels
+- `tests/test_commit_tool.py` — 9 Python тестов через `_ts_loader.mjs` (exec_stub_json): load, valid, no scope, Cyrillic, multiline, >72, no staged, wrong type, cwd propagation
+- `tests/test_create_pr_tool.py` — 8 Python тестов: load, valid, missing scope, missing headings, Latin-only, issue linkage, cwd propagation
+- `tests/test_create_issue_tool.py` — 10 Python тестов: load, valid, >80, 80 boundary, missing sections, Latin-only, labels, cwd propagation
+- ADR-015 + этот handoff
+
+## Почему
+Оптимизация AGENTS.md: вынос детерминированной логики (commits, PRs, issues) в tools с встроенной валидацией. Все правила форматов переносятся из skills в код tools — агент вызывает tool, tool валидирует и исполняет. Это первый PR из серии из 3 (build → lock → switch). Паттерн `merge-pr.ts` (PR#30, ADR-010): thin TS wrapper → spawnSync → `context.worktree` как cwd. Tools auto-discovered через `@opencode-ai/plugin` — НЕ зарегистрированы в opencode.json (подтверждение паттерна PR#30/#36).
+
+Спека issue содержала 2 противоречия, зафиксированы (не додумывал, продолжал по спеке):
+1. **create-issue.ts labels spread bug**: `["--label", ...labels]` создаёт `["--label", "bug", "enhancement"]`, но `gh` принимает `--label` с одним значением. Исправлено на `["--label", labels.join(",")]` → `--label bug,enhancement` (gh comma-синтаксис)
+2. **Cyrillic check unreachable**: спека требует validation order: headings (Cyrillic) → Cyrillic check. Поскольку headings сами содержат Cyrillic (`## Что сделано`, `## Контекст`), body прошедший heading check всегда проходит Cyrillic check. Latin-only body падает на heading check, не на Cyrillic. Тесты adjusted: `test_latin_only_body` проверяет reachable behavior (heading error), не unreachable Cyrillic error. Cyrillic check оставлен как defense-in-depth (если headings изменятся на English в будущем)
+
+## Pending
+- AGENTS.md не обновлялся — вне scope этого PR. Правила форматов теперь дублируются (AGENTS.md текст + tools код). Future PR может заменить AGENTS.md rules на "use commit/create-pr/create-issue tools" references
+- Skills `commit`/`issue` содержат те же правила в тексте — дублирование с tool кодом. Future cleanup может сократить skills до "load tool" pointers
+- `test_latin_only_body` test name сохранён для совместимости со спекой, но проверяет heading error (не Cyrillic). Если validation order изменится (Cyrillic перед headings) — test нужно будет обновить
+
+## Watch out
+- `_ts_loader.mjs` расширен новыми функциями (`buildExecArgsFromJson`, `buildStubSequencer`, `exec_stub_json` mode). Существующие `exec_stub`/`exec_real`/`load` modes не изменены — обратная совместимость сохранена. Новые multi-arg tools (commit, create-pr, create-issue) используют `exec_stub_json`; существующие single-arg tools (pipeline-status, spec-status, memory-setup) продолжают использовать `exec_stub`
+- `commit.ts` делает 2 spawnSync вызова на success path (git diff --cached, git commit) и до 2 на error path (git diff, git log). Тесты должны предоставлять последовательные stub responses
+- create-issue.ts `labels` join: `["bug", "enhancement"]` → `"bug,enhancement"` (comma-joined, НЕ separate `--label` flags). gh CLI принимает comma-синтаксис
+- Cyrillic check в create-pr/create-issue — defense-in-depth, фактически unreachable из-за heading checks (headings содержат Cyrillic). Не удалять — защита от будущих изменений headings на English
+- Tools auto-discovered через `@opencode-ai/plugin` — НЕ нужно регистрировать в opencode.json (подтверждение паттерна PR#30/#36)
+- TS-тесты (`test_*.ts`) — документационные, CI гоняет Python-версии через `_ts_loader.mjs` (bun нет на runner)
+- ADR number = sequential (015), НЕ PR number. Эволюция известного паттерна (PR#26 docs-reviewer typo — записал PR number как ADR number)

+"""Tests for .opencode/tools/commit.ts — the commit custom tool.
+
+Mirrors tests/test_pipeline_status_tool.py / test_memory_setup_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/commit.ts``.
+
+Modes used:
+- ``load`` — sanity-check that the tool loads and declares ``message`` arg.
+- ``exec_stub_json`` — call execute with a stubbed spawnSync to verify:
+  (a) success path: valid message + staged files → "Committed: <msg>",
+  (b) validation errors: no scope, Cyrillic, multiline, >72, no staged,
+      wrong type.
+
+commit.ts makes up to 2 spawnSync calls: ``git diff --cached --name-only``
+(staged check) and ``git commit`` (success path), or ``git log --oneline -5``
+(error path appends recent commits). The stub sequencer returns responses
+in order per call.

+"""Tests for .opencode/tools/create-pr.ts — the create-pr custom tool.
+
+Mirrors tests/test_pipeline_status_tool.py / test_memory_setup_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/create-pr.ts``.
+
+Modes used:
+- ``load`` — sanity-check that the tool loads and declares title, body,
+  issue_number args.
+- ``exec_stub_json`` — call execute with a stubbed spawnSync to verify:
+  (a) success path: valid title + body → "PR created: <url>",
+  (b) validation errors: missing scope, missing headings, Latin-only body,
+  (c) issue linkage: issue_number → body gets "Closes #N" appended.
+
+create-pr.ts makes 1 spawnSync call (gh pr create) on the success path.

+/**
+ * Tests for .opencode/tools/create-pr.ts — the create-pr custom tool.
+ *
+ * Mirror of tests/test_pipeline_status_tool.ts / test_memory_setup_tool.ts:
+ * the tool is a spawnSync wrapper around `gh pr create` with title/body
+ * validation.
+ *
+ * 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_create_pr_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_create_pr_tool.py):
+ *   - test_valid_pr — valid title + body → "PR created: <url>"
+ *   - test_missing_scope — title without scope → error
+ *   - test_missing_chto_sdelano — body missing ## Что сделано → error
+ *   - test_missing_pochemu — body missing ## Почему → error
+ *   - test_latin_only_body — body without Cyrillic → error
+ *   - test_issue_linkage — issue_number → body gets Closes #N
