Production Check Skill

Purpose: Verify code is production-ready by running build, lint, and test commands Trigger: After code changes, before deployment or sign-off Input: Working directory, package manager (pnpm) Output: { passed: boolean, build_result, lint_result, test_result, failures[] }

Workflow

1. Verify working directory and package manager

• Confirm cwd is monorepo root
• Verify pnpm is available (pnpm --version)
• If package manager not found: return error

2. Run pnpm build

• Execute: pnpm build (or pnpm build --filter=... if scoped)
• Capture stdout/stderr
• Status: ✓ pass or ✗ fail
• If turbo available: runs in parallel (turbo handles dependencies)

3. Run pnpm lint

• Execute: pnpm lint
• Capture stdout/stderr
• Status: ✓ pass or ✗ fail
• Non-blocking if only warnings

4. Run pnpm test

• Execute: pnpm test (or pnpm test --run for CI mode)
• Capture stdout/stderr
• Status: ✓ pass or ✗ fail
• Can fail tests but collect results

5. Aggregate results

• Collect all failures into array
• Return final status (passed = all 3 commands succeeded)
• Provide diagnostic output for fixing

Output Format

Success Case:

{
  "passed": true,
  "build_result": {
    "status": "pass",
    "duration": "12s"
  },
  "lint_result": {
    "status": "pass",
    "warnings": 0
  },
  "test_result": {
    "status": "pass",
    "tests": "42 passed"
  },
  "failures": []
}

Failure Case:

{
  "passed": false,
  "build_result": {
    "status": "fail",
    "error": "TypeScript compilation failed",
    "stderr": "src/types.ts:45: error TS2322: Type 'string' not assignable to type 'number'"
  },
  "lint_result": {
    "status": "pass"
  },
  "test_result": {
    "status": "fail",
    "error": "2 tests failed",
    "stderr": "FAIL  src/__tests__/auth.spec.ts"
  },
  "failures": [
    "Build failed: TypeScript compilation",
    "Tests failed: 2 tests in src/__tests__/auth.spec.ts"
  ]
}

Error Handling

Key Rules

• Root execution: Always run from monorepo root (pwd must show root)
• Turbo optimization: If turbo.json exists, pnpm build uses turbo (automatic)
• Parallel execution: Build runs in parallel (turbo handles), lint and test sequential
• Capture output: All stdout/stderr captured for diagnostics
• No modifications: Read-only execution, no file changes

Integration

Called by:

• /build command (validation phase)
• /audit command (quality validation)
• validation-phase skill (before reporting)

Calls: pnpm scripts (no subagents)

Next step: Report results to calling agent for decision

Example

Input:

cwd: "/home/user/monorepo"
package_manager: "pnpm"

Execution:

$ cd /home/user/monorepo
$ pnpm build
→ ✓ Build succeeded (12s)

$ pnpm lint
→ ✓ Lint passed

$ pnpm test --run
→ ✓ 42 tests passed

Output:

{
  "passed": true,
  "build_result": { "status": "pass", "duration": "12s" },
  "lint_result": { "status": "pass", "warnings": 0 },
  "test_result": { "status": "pass", "tests": "42 passed" },
  "failures": []
}
