Dev Security - Security Audit

Delegate to Sentinel for comprehensive security review.

Philosophy

"Every line of code is guilty until proven innocent."

Flow

1. Context Gathering

# What changed?
git diff --name-only HEAD~10 2>/dev/null || git diff --name-only

# What's the scope?
ls -la

2. Invoke Sentinel

Delegate to Sentinel agent:

"Sentinel, security audit time.

Scope: {describe what changed or focus area}

Run your full checklist:
1. Secrets scan
2. Dependency audit
3. Injection vectors
4. Auth/authz review
5. Crypto check

Files changed: {list from git diff}

Be thorough. We're not shipping vulnerabilities."

3. Review Sentinel's Findings

Sentinel returns findings by severity:

CRITICAL: Must fix before merge
HIGH: Should fix before merge
MEDIUM: Should fix soon
LOW: Consider fixing

4. Action on Findings

If CRITICAL or HIGH found:

Security audit found issues:

CRITICAL:
- [Issue 1 with location and fix]

HIGH:
- [Issue 2 with location and fix]

Options:
1. Fix now (Bob will implement Sentinel's fixes)
2. Fix manually, run /dev-security again
3. Accept risk (requires explicit acknowledgment)
4. Get second opinion (run deeper audit)

If only MEDIUM/LOW:

Security audit passed with notes.

MEDIUM:
- [Issue with suggestion]

LOW:
- [Issue with suggestion]

These don't block shipping but should be tracked.
Add to backlog? (y/n)

If clean:

Security audit passed!

Sentinel says: "Huh. Someone actually read the OWASP guide. Respect."

Ready for:
- /dev-rc - Release candidate
- /dev-finish - Close the cycle

5. Log Results

If active dev-cycle session:

## Security Audit
- **Date**: {timestamp}
- **Status**: PASSED | PASSED_WITH_NOTES | FAILED
- **Critical**: 0
- **High**: 0
- **Medium**: 2
- **Low**: 1

### Findings
{Summary of what was found and resolved}

Focus Modes

Full Audit (default)

/dev-security

Everything: secrets, deps, code, config, infra

Quick Scan

/dev-security quick

Just the critical stuff: secrets, known CVEs, obvious injection

Specific Focus

/dev-security auth
/dev-security crypto
/dev-security deps
/dev-security secrets

Focus on one area for deeper review.

What Sentinel Checks

Area	What	Why
Secrets	Hardcoded keys, tokens, passwords	#1 breach cause
Dependencies	Known CVEs, outdated packages	Supply chain attacks
Injection	SQL, XSS, command, path traversal	OWASP Top 10
Auth	Broken auth, missing authz	Gateway to everything
Crypto	Weak algorithms, hardcoded keys	Data protection
Config	Exposed debug, permissive CORS	Misconfiguration

Integration

With dev-cycle: Logs findings to session With dev-rc: Security must pass for release candidate With Bob: Implements fixes for findings With Sentinel: The security brain

When to Run

Before any PR
After implementing auth/authz
After adding new dependencies
After handling user input
After touching crypto
Before any release
When Sentinel whispers "trust nothing"
