description	This skill should be used when handling verification steps, quality gates, pre-commit checks, test failures, lint errors, build verification, or mandatory validation before task completion.

Verification Gates

Overview

Verification gates are mandatory quality checkpoints that must pass before any implementation work is considered complete. These gates prevent broken code from being committed, ensure type safety, maintain code style consistency, and validate that all tests pass.

Owner Agent: Alphonse (Verifier Agent)

Key Principles

1. Non-Negotiable Quality: Every code change must pass all applicable gates
2. Automated Enforcement: Gates are triggered automatically via hooks
3. Clear Feedback: Failures provide actionable error messages
4. Project-Aware: Commands adapt to detected project type and tooling
5. Fail-Fast, Fix-First: When any gate fails, work stops until resolved

Gate Types

Pre-Commit Gates

Check	Example Command	Timeout
Lint	npm run lint / ruff check	30s
Format	npm run format:check / black --check	15s
Quick Tests	Changed file tests only	60s

Pre-Complete Gates

Check	Example Command	Timeout
Full Test Suite	npm test / pytest	300s
Type Checking	npx tsc --noEmit / mypy .	120s
Linting	Full codebase lint	60s
Build	npm run build / python -m build	180s

Security Gates

Triggered by changes to sensitive files or security-critical code:

Check	Trigger	Action
Credential Scan	*.env, *secret*, *.key	Block + Alert
Permission Check	Auth/ACL code	Require review
Dependency Audit	Package files	npm audit / pip-audit

---

Verification Commands

Quick Reference by Language

Action	Node.js	Python	Go	Rust
Test	npm test	pytest	go test ./...	cargo test
Types	npx tsc --noEmit	mypy .	go build	cargo check
Lint	npm run lint	ruff check .	golangci-lint run	cargo clippy
Build	npm run build	python -m build	go build	cargo build

For complete command reference, see references/verification-commands.md.

Verification Process

Alphonse Verification Steps

1. Identify project type (Node.js, Python, Go, Rust, Java)
2. Run test suite with appropriate framework
3. Execute type checking if configured
4. Run linters if present
5. Attempt production build
6. Report structured results

Standard Output Format

## Verification Results

### Tests
- Status: [PASS | FAIL]
- Output: [Summary of test execution]

### Type Check
- Status: [PASS | FAIL | SKIPPED]
- Errors: [List of type errors if any]

### Lint
- Status: [PASS | FAIL | SKIPPED]
- Warnings: [Count and summary]

### Build
- Status: [PASS | FAIL | SKIPPED]
- Issues: [Build errors if any]

### Overall: [VERIFIED | FAILED | ENVIRONMENT_BLOCKED]

Failure Handling

Failure Severity

Type	Severity	Action
Test Failure	BLOCKING	Fix and re-run
Type Error	BLOCKING	Resolve types
Lint Error	BLOCKING	Auto-fix or manual
Build Failure	BLOCKING	Fix compilation
Security Alert	CRITICAL	Immediate remediation
Timeout	WARNING	Retry once
Flaky Test	WARNING	Retry 3x, then fix

Escalation Path

Alphonse Reports -> Loid Reviews
     |                   |
Simple Fix?         Complex Issue?
     |                   |
    YES                  NO
     |                   |
Loid Fixes      Escalate to Lawliet
     |                   |

Best Practices

DO

• Run verification after every significant change
• Fix failures immediately
• Trust Alphonse's verdict
• Add tests for new features
• Run full suite before PR

DON'T

• Skip verification to save time
• Suppress type errors with any
• Disable lint rules without justification
• Commit with failing tests
• Use --no-verify flag
• Mark tasks complete without verification

Gate Selection Guide

Scenario	Gate Type	Checks Run
Small code fix	Pre-Commit	Lint, format, affected tests
New feature complete	Pre-Complete	Full suite, types, lint, build
Security-related change	Security	Credential scan, audit, permissions
Cross-service change	Integration	E2E, contracts, compatibility

---

Override Rules

Verification gates can ONLY be skipped when:

1. User explicitly requests skip - Must be documented
2. No code changes were made - Documentation-only tasks
3. Task is purely exploratory - No production impact

Override Documentation Required:

## Verification Override

Reason: [Explicit reason for skipping]
Requested by: [User or escalation source]
Risk Assessment: [Low/Medium/High]
Compensating Controls: [What will catch issues later]

---

Multi-reviewer disagreement (Codex co-review)

Disagreement rule: See the canonical truth table in commands/orchestrate.md Phase 4 (Codex co-review). The summary: Lawliet's NEEDS_CHANGES always wins; Codex's NEEDS_CHANGES/BLOCKED requires a file:line citation to flip the verdict.
