Verification Loop

Continuous verification throughout development.

Verification Levels

Quick (30 seconds)

•Critical tests only
•Type check
•Lint check

Standard (2 minutes)

•All tests
•Type check
•Lint check
•Build verification

Full (5+ minutes)

•Standard checks
•E2E tests
•Security scan
•Performance check

Commands

bash

/verify quick        # Quick smoke tests
/verify              # Standard verification
/verify full         # Comprehensive verification
/verify [checkpoint] # Verify against specific checkpoint

Checkpoint System

Creating Checkpoints

markdown

# Checkpoint: user-auth-oauth

## State

- Branch: feature/user-auth
- Files: 15 changed
- Tests: 12 passing

## Success Criteria

- [ ] OAuth flow completes successfully
- [ ] User session persisted correctly
- [ ] Error handling works for failures
- [ ] Tests cover all code paths

## Verification Commands

bun test test/auth/oauth.test.ts
bun run typecheck

## Rollback

git checkout checkpoint-user-auth-oauth

Verifying Against Checkpoints

Run the verification commands and ensure all success criteria are met.

Verification Report

markdown

# Verification Report

## Tests
- 42 passing
- 2 failing

## Type Check
- No errors

## Linter
- 3 warnings

## Build
- Success

## Status: FAILED
Fix failing tests before committing.

## Failing Tests
1. test/auth/login.spec.ts:15 - should handle invalid password
2. test/auth/login.spec.ts:23 - should handle network errors

Auto-Verification Hooks

Configure hooks to run verification automatically:

json

{
  "hooks": {
    "PreToolUse": {
      "verify_before_commit": {
        "pattern": "Bash",
        "command_pattern": "git commit",
        "actions": [
          {
            "type": "run_command",
            "command": "bun test && bun tsc --noEmit"
          }
        ]
      }
    }
  }
}

Monitoring

Set up continuous monitoring in CI:

yaml

# .github/workflows/verify.yml
name: Verify
on: [push, pull_request]

jobs:
  verify:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: bun install
      - run: bun test
      - run: bun run typecheck
      - run: bun run lint

Rollback Strategy

When verification fails:

•Identify breaking change
•Revert to last checkpoint
•Fix the issue
•Re-verify
•Move forward

bash

# List recent checkpoints
git log --oneline --grep="checkpoint"

# Checkout specific checkpoint
git checkout <checkpoint-sha>

# Or use git reset
git reset --hard <checkpoint-sha>
