Verification Gate

Overview

Part of the hidden validation layer. User never sees this running, but it prevents false "Done!" claims.

Core principle: Never show success to user without evidence.

When This Runs (Automatically)

• Before displaying "✅ Done!"
• Before showing preview URL
• Before /mvp:deploy
• After any /mvp:add feature

The Gate Checklist

BEFORE showing success to user:

[ ] Tests pass (run full suite, not partial)
[ ] Build succeeds (no compilation errors)
[ ] No TypeScript/linting errors
[ ] Feature actually works (manual smoke test)
[ ] Security checks pass (from security-check skill)
[ ] Code review clean (from code-review-auto skill)

ALL must pass. ANY failure = fix silently, don't show error to user.

User Experience

What user sees:

Adding login feature...
✅ Done! Check your preview.

What happens behind the scenes:

1. Generate login code
2. Run tests → 2 failures
3. Fix failures automatically
4. Run tests → pass
5. Run build → pass
6. Security check → pass
7. Code review → 1 minor issue
8. Fix issue automatically
9. All gates pass → show "Done!"

Failure Handling

If gate fails and can auto-fix:

• Fix silently
• Re-run verification
• User never knows

If gate fails and cannot auto-fix:

• Ask simple question (no technical jargon)
• Example: "Should login require email confirmation?"
• NOT: "The auth middleware threw ValidationError"

Automation Script

Run all checks programmatically:

python scripts/verify.py --path /project/path --language rust
python scripts/verify.py --path /project/path --json  # JSON output

The script auto-detects language and runs appropriate checks.

Integration

Called by:

• /mvp:build - Before showing preview
• /mvp:add - Before confirming feature added
• /mvp:deploy - Before deployment

Uses:

• auto-testing - Run test suite
• security-check - Security validation
• code-review-auto - Code quality check
• scripts/verify.py - Deterministic verification

Philosophy

User paid for "vibe coding" - they describe what they want, we handle how.

Showing them test failures or build errors breaks the magic.

Fix it. Don't explain it.
