Gathering Security

Gathering Security 🌲🕷️🦝🐢

The drum echoes in the shadows. The Spider weaves intricate webs of authentication, each strand placed with precision. The Raccoon rummages through every corner, finding what doesn't belong, cleaning what could harm. The Turtle moves with ancient patience, layering defense upon defense, testing every plate of the shell. Together they secure the forest — doors locked tight, secrets safe, paths protected, and the ground itself hardened against anything that comes.

When to Summon

• Implementing authentication systems
• Adding OAuth or session management
• Security auditing before launch
• After security incidents
• Preparing for production deployment
• When auth, security audit, and deep hardening must work together
• Building a new feature that handles sensitive data
• Hardening existing code for defense in depth

Grove Tools for This Gathering

Use gw and gf throughout. Quick reference for security work:

# Find security-relevant code patterns
gf --agent search "sanitize|escape|validate"  # Security patterns
gf --agent auth                     # Find auth code and middleware

# Verify security changes don't break anything
gw ci --affected --diagnose         # Run CI on affected packages

Animals Mobilized

1. 🕷️ Spider — Weave authentication webs with patient precision
2. 🦝 Raccoon — Rummage for security risks and cleanup
3. 🐢 Turtle — Harden with layered, defense-in-depth protection

Phase 1: SUMMON

The drum sounds. The shadows shift...

Receive and parse the request:

Clarify the Security Work:

• Adding new auth provider? (OAuth, SSO)
• Securing routes and APIs?
• General security audit?
• Deep security hardening?
• Post-incident cleanup?
• Pre-production hardening?

Error Codes as Security Posture: All errors MUST use Signpost codes — this is a security requirement, not just a convention:

• All server errors use codes from the appropriate catalog (API_ERRORS, AUTH_ERRORS, etc.)
• userMessage is always generic and warm — no technical details leak to clients
• adminMessage is detailed — stays in server logs only
• Auth errors NEVER reveal user existence ("Invalid credentials" — not "user not found")
• logGroveError() for all server errors — never console.error alone

Scope Check:

"I'll mobilize a security gathering for: [security work]

This will involve:

• 🕷️ Spider weaving authentication
  • OAuth/PKCE flow
  • Session management
  • Route protection
  • Token handling
• 🦝 Raccoon auditing security
  • Secret scanning
  • Vulnerability check
  • Dependency audit
  • Dead code removal
• 🐢 Turtle hardening defenses
  • Input/output validation
  • Security headers & CSP
  • Defense-in-depth enforcement
  • Exotic attack vector testing
  • Hardening report

Proceed with the gathering?"

Selective Mobilization: Not every gathering needs all three animals:

Phase 2: ORGANIZE

The animals take their positions in the shadows...

Dispatch in sequence:

Full Dispatch Order:

Spider ──→ Raccoon ──→ Turtle
   │          │            │
   │          │            │
Weave      Audit       Harden
Auth       Secrets     Defenses

Dependencies:

• Spider must complete before Raccoon (needs auth to audit)
• Raccoon should complete before Turtle (clean first, then harden)
• May iterate: Turtle findings → Spider/Raccoon fixes → Turtle re-verify

Iteration Cycle (When Vulnerabilities Found):

Iteration Rules:

• Turtle finds auth vulnerability → Spider patches → Turtle re-verifies
• Turtle finds non-auth vulnerability → Fix directly → Turtle re-verifies
• Raccoon finds secrets → Raccoon cleans → Turtle verifies no residual exposure
• Maximum 3 iterations per issue (if more needed, architectural review required)
• Each iteration focuses only on newly found/fixed items
• Document all iterations in final report

Phase 3: EXECUTE

The web is woven. The audit begins. The shell hardens...

Execute each animal's phase by loading and running their dedicated skill:

🕷️ SPIDER — WEAVE

Load skill: spider-weave

Execute the full Spider workflow for [the auth system being implemented]. Handoff: working authentication system (OAuth flow, session management, protected routes, CSRF protection) → Raccoon for audit

🦝 RACCOON — AUDIT

Load skill: raccoon-audit

Execute the full Raccoon workflow on the entire codebase, with particular attention to the Spider's auth implementation. If secrets found or auth issues discovered → Spider patches → Raccoon re-verifies. Handoff: clean audit report (no secrets, vulnerabilities patched, dead code removed, pre-commit hooks installed) → Turtle for hardening

🐢 TURTLE — HARDEN

Load skill: turtle-harden

Execute the full Turtle workflow on the codebase, including auth routes, API endpoints, and data flows. If deep vulnerabilities found in auth → Spider patches → Turtle re-verifies. Maximum 3 iterations per issue. Handoff: hardening report (defense-in-depth verified, exotic vectors tested, all layers applied) → VALIDATE phase

Phase 4: VALIDATE

The web holds. The audit confirms. The shell endures...

Validation Checklist:

• Spider: Auth flow works end-to-end
• Spider: Routes properly protected
• Spider: Sessions expire correctly
• Spider: CSRF protection active
• Raccoon: No secrets in codebase
• Raccoon: Dependencies up to date
• Raccoon: No sensitive data in logs
• Raccoon: Pre-commit hooks installed
• Turtle: Input validation on all entry points
• Turtle: Output encoding on all exit points
• Turtle: Security headers complete
• Turtle: CSP enforced (nonce-based)
• Turtle: CORS restricted to exact origins
• Turtle: Defense-in-depth verified (2+ layers per critical function)
• Turtle: Exotic attack vectors tested and clear
• Turtle: Multi-tenant isolation verified (if applicable)

Security Test Cases:

Authentication:
[ ] Login redirects to provider
[ ] Callback exchanges code for tokens
[ ] Sessions created correctly
[ ] Logout clears sessions server-side
[ ] Expired tokens rejected
[ ] Session fixation prevented

Authorization:
[ ] Protected routes require auth
[ ] Admin routes check roles
[ ] API endpoints verify tokens
[ ] Users can't access others' data (IDOR tested)
[ ] Horizontal escalation prevented
[ ] Vertical escalation prevented

Hardening:
[ ] SQL injection prevented (parameterized queries)
[ ] XSS prevented (output encoding + CSP)
[ ] CSRF prevented (tokens + SameSite cookies)
[ ] File uploads sanitized (type + size + rename)
[ ] Rate limiting active on all sensitive endpoints
[ ] Prototype pollution vectors blocked
[ ] Timing attacks mitigated (constant-time comparison)
[ ] Race conditions prevented (atomic operations)
[ ] SSRF prevented (URL allowlist, no redirect following)

Phase 5: COMPLETE

The gathering ends. The forest is fortified...
