Validate Command

Purpose: Quantitative validation - runs automated checks (types, lint, tests, build).

Distinct from /review: This command runs automated tooling. Use /review first for qualitative code review (style, security, best practices).

Workflow: /review → /validate → /ship

Run all validations before shipping code. Automatically detects the project's tech stack and runs only relevant checks.

1. Detect Tech Stack

First, check which config files exist to determine the project type:

• package.json → Node.js/TypeScript project
• tsconfig.json → TypeScript
• pyproject.toml or requirements.txt → Python
• Cargo.toml → Rust
• go.mod → Go

Use Glob to check for these files before running language-specific checks.

2. Run Relevant Checks

TypeScript/Node.js (if package.json exists)

Type checking: !npx tsc --noEmit 2>&1 || true

Linting (if lint script exists): !npm run lint 2>&1 || true

Tests: !npm test 2>&1 || true

Build: !npm run build 2>&1 || true

Python (only if pyproject.toml or requirements.txt exists)

Linting: !ruff check . 2>&1 || true

Type checking: !mypy . 2>&1 || true

Tests: !pytest -q 2>&1 || true

Rust (only if Cargo.toml exists)

Check: !cargo check 2>&1 || true

Clippy: !cargo clippy -- -D warnings 2>&1 || true

Tests: !cargo test 2>&1 || true

Go (only if go.mod exists)

Build: !go build ./... 2>&1 || true

Vet: !go vet ./... 2>&1 || true

Tests: !go test ./... 2>&1 || true

3. SelfCheck Protocol

Answer these questions with evidence:

Q1: Are tests passing?

• Show actual test output
• Report pass/fail counts

Q2: Are all requirements met?

• Map requirements to implementation
• Confirm nothing missed

Q3: No unverified assumptions?

• External APIs verified
• Libraries documented

Q4: Is there evidence?

• Include validation output
• Show build success

Report Format

## Validation Report

### Tech Stack Detected
[List detected languages/frameworks]

### Type Checking
[✅ Passed / ❌ Failed / ⏭️ Skipped (not applicable)]
[Details if failed]

### Linting
[✅ Passed / ❌ Failed / ⏭️ Skipped (not applicable)]
[Details if failed]

### Tests
[✅ X passed, Y failed / ❌ Failed to run / ⏭️ Skipped]
[Failure details if any]

### Build
[✅ Passed / ❌ Failed / ⏭️ Skipped (not applicable)]
[Details if failed]

### Summary
[READY TO SHIP / NEEDS FIXES]

Next Steps

• If all pass: /ship to commit
• If issues found: Fix and re-run /validate
