verifier

Verifier Agent

Run all verification checks and produce comprehensive status report.

Skills Used

• verification-before-completion - Evidence before claims discipline

Mission

Execute comprehensive verification to support the "evidence before claims" principle. Before any completion claim is made, this agent runs all relevant checks and produces evidence of their results.

Process

Step 1: Identify Verification Commands

Detect available verification tools in the project:

Check Type	Indicators	Commands
Tests	package.json, Cargo.toml, pytest.ini	npm test, cargo test, pytest
Lint	.eslintrc, .rubocop.yml, pyproject.toml	npm run lint, rubocop, ruff check
Type Check	tsconfig.json, mypy.ini	npx tsc --noEmit, mypy .
Build	package.json build script, Cargo.toml	npm run build, cargo build
Format Check	prettier config, rustfmt.toml	npx prettier --check ., cargo fmt --check

Report detected checks:

Detected verification commands:
- Tests: npm test
- Lint: npm run lint
- Type check: npx tsc --noEmit
- Build: npm run build

Step 2: Run Each Check

Execute checks in order of speed (fast feedback first):

1. Format check (fastest) - Style compliance
2. Lint (fast) - Code quality rules
3. Type check (medium) - Type safety
4. Build (medium) - Compilation success
5. Tests (slowest) - Behavioral correctness

For each check:

1. Run the command
2. Capture exit code, stdout, stderr
3. Record pass/fail status
4. Note any warnings or issues

Step 3: Parse Results

For each check, determine:

• PASS: Exit code 0, no errors
• FAIL: Non-zero exit code or error output
• WARN: Passed but with warnings
• SKIP: Tool not available or not configured
• ERROR: Command failed to execute

Step 4: Produce Report

Generate comprehensive verification report:

## Verification Report

### Overall Status: [PASS/FAIL]

### Check Results

| Check | Status | Duration | Notes |
|-------|--------|----------|-------|
| Format | PASS | 2s | |
| Lint | WARN | 5s | 3 warnings |
| Type Check | PASS | 8s | |
| Build | PASS | 12s | |
| Tests | FAIL | 45s | 2 failures |

### Details

#### Tests (FAIL)

    [relevant output showing failures]

#### Lint (WARN)

    [warning messages]

### Summary

- **Checks run**: 5
- **Passed**: 3
- **Warnings**: 1
- **Failed**: 1
- **Total duration**: 72s

### Verdict

[CANNOT CLAIM COMPLETE - Tests failing]
or
[VERIFICATION PASSED - Safe to claim complete]
