quality-gates

Quality Gates — Reference Skill

This skill defines the canonical quality check commands. Do NOT invoke this skill directly. Consuming skills (session-start, wave-executor, session-end, session-reviewer) reference the variant they need and execute the commands inline.

Command Resolution (policy-file-first, #183)

Quality-gate commands are resolved in this priority order:

1. .orchestrator/policy/quality-gates.json — canonical policy file (preferred). Schema: .orchestrator/policy/quality-gates.schema.json. Bootstrap writes a package-manager-aware default; hand-edit to customize.
2. Session Config test-command / typecheck-command / lint-command in CLAUDE.md (Claude Code / Cursor) or AGENTS.md (Codex CLI) — fallback.
3. Hardcoded defaults — last resort: pnpm test --run, tsgo --noEmit, pnpm lint.

Loader: scripts/lib/quality-gates-policy.mjs exports loadQualityGatesPolicy(repoRoot) and resolveCommand(policy, key, fallback). The Bash-side runner scripts/run-quality-gate.sh performs the same resolution inline inside extract_command().

If any resolved command is set to the literal string skip, skip that check entirely.

Session Config Fields (legacy fallback)

Read these from the project's ## Session Config section when .orchestrator/policy/quality-gates.json is absent:

• test-command — Custom test command.
• typecheck-command — Custom typecheck command.
• lint-command — Custom lint command.

If a field is missing, use the hardcoded default.

Variant 1: Baseline

Used by: session-start (Phase 3) Purpose: Quick health check at session start — non-blocking.

Commands:

1. Run {typecheck-command} 2>&1 | tail -5
2. Run {test-command} 2>&1 | tail -5

Behavior: Report results but do NOT block the session. Capture error counts and store them as the session baseline for later comparison.

Script output schema (Baseline):

{"variant": "baseline", "typecheck": {"status": "pass|fail|skip", "output": "string"}, "test": {"status": "pass|fail|skip", "output": "string"}}

Variant 2: Incremental

Used by: wave-executor (after implementation waves) Purpose: Verify implementation waves did not break anything.

Commands:

1. Run {test-command} on changed files only (e.g., pnpm test -- <changed-test-files>).
2. Run {typecheck-command}.

Behavior: Report failures. If issues are found, add fix tasks to the next wave automatically. Do not block wave progression — let the next wave address regressions.

Metrics output (for consuming skills to capture):

{
  "variant": "incremental",
  "duration_seconds": null,
  "typecheck": "pass|fail|skip",
  "test": "pass|fail|skip",
  "errors": []
}

Variant 3: Full Gate

Used by: session-end (Phase 2) Purpose: Final quality gate before commit — MUST pass.

Commands:

1. Run {typecheck-command} — must produce 0 errors.
2. Run {test-command} — must pass (exit code 0).
3. Run {lint-command} — must pass (warnings OK, errors NOT OK).
4. Check changed files for debug artifacts: console.log, debugger, TODO: remove.

Behavior: BLOCKING. Do not commit if any check fails. Fix quick issues (<2 min) inline. For anything longer, create a priority:high issue and proceed without committing the affected files.

Metrics output (for consuming skills to capture):

{
  "variant": "full-gate",
  "duration_seconds": null,
  "typecheck": {"status": "pass|fail|skip", "error_count": 0},
  "test": {"status": "pass|fail|skip", "total": 0, "passed": 0},
  "lint": {"status": "pass|fail|skip", "warnings": 0},
  "debug_artifacts": []
}

Variant 4: Per-File

Used by: session-reviewer agent Purpose: Targeted quality check on specific changed files.

Commands:

1. Run {test-command} on specific file paths passed by the reviewer.
2. Run {typecheck-command}.

Behavior: Report per-file pass/fail status. The reviewer uses these results to annotate its review output.

Script output schema (Per-File):

{"variant": "per-file", "typecheck": {"status": "pass|fail|skip"}, "test": {"status": "pass|fail|skip"}, "files": ["string"]}

Graceful Degradation

Handle missing tools without failing the session:

• If {typecheck-command} fails with "command not found" → skip TypeScript checks, note "No TypeScript configured".
• If {test-command} fails with "command not found" → skip tests, note "No test runner configured".
• If {lint-command} fails with "command not found" → skip lint, note "No linter configured".
• Non-TypeScript projects should set typecheck-command: skip in Session Config.

Always continue with the remaining checks — never abort a variant because one tool is missing.

How Other Skills Reference This

When a consuming skill needs quality checks, include this directive:

Quality Reference: Run [Baseline|Incremental|Full Gate|Per-File] quality checks per the quality-gates skill. Read test-command, typecheck-command, and lint-command from Session Config (defaults: pnpm test --run, tsgo --noEmit, pnpm lint).

Replace the bracketed variant name with the specific variant required by that phase.

Script Alternative

Prefer scripts/run-quality-gate.sh for deterministic execution with structured JSON output. The inline command approach is supported but produces unstructured output that downstream consumers cannot reliably parse.

# Baseline (session-start)
bash "${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-$PLUGIN_ROOT}}/scripts/run-quality-gate.sh" --variant baseline --config "$CONFIG"

# Incremental (wave-executor)
bash "${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-$PLUGIN_ROOT}}/scripts/run-quality-gate.sh" --variant incremental --config "$CONFIG" --files changed-file1.ts,changed-file2.ts

# Full Gate (session-end)
bash "${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-$PLUGIN_ROOT}}/scripts/run-quality-gate.sh" --variant full-gate --config "$CONFIG" --session-start-ref "$SESSION_START_REF"

# Per-File (session-reviewer)
bash "${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-$PLUGIN_ROOT}}/scripts/run-quality-gate.sh" --variant per-file --config "$CONFIG" --files specific-file.ts

The script handles graceful degradation (missing tools → skip), structured JSON output matching the schemas above, and proper exit codes (0=pass, 1=error, 2=gate-failed).
