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:

bash

# 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

🕷️ Spider — Weave authentication webs with patient precision
🦝 Raccoon — Rummage for security risks and cleanup
🐢 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:

Situation	Animals Needed
New auth system + full security	All three: Spider → Raccoon → Turtle
Auth already exists, need hardening	Raccoon → Turtle
New feature, ensure secure by design	Turtle only (or Turtle → Raccoon)
Secrets leak / incident response	Raccoon → Spider (rotate creds) → Turtle (verify)
Pre-production deploy	Raccoon → Turtle

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:

🕷️ SPIDER — WEAVE

"Spinning the authentication threads..."

Phase: SPIN
- Choose auth pattern (OAuth 2.0 + PKCE, JWT, Session)
- Set up infrastructure (client registration, secrets)

Phase: CONNECT
- Implement OAuth flow (login/callback)
- Session/token management
- User info fetching

Phase: SECURE
- Route protection middleware
- CSRF protection
- Rate limiting
- Security headers

Phase: TEST
- Auth flow end-to-end
- Error handling
- Edge cases

Phase: BIND
- Documentation
- Environment variables
- Monitoring

Output:
- Working authentication system
- Protected routes
- Session management

🦝 RACCOON — AUDIT

"Rummaging through every corner..."

Phase: RUMMAGE
- Search for secrets in code
- Check git history
- Scan dependencies for vulnerabilities

Phase: INSPECT
- Validate auth implementation
- Check input validation
- Review access controls
- Examine error messages

Phase: SANITIZE
- Remove any secrets found
- Rotate exposed credentials
- Patch vulnerabilities

Phase: PURGE
- Clean git history if needed
- Remove dead code
- Clear old tokens

Phase: VERIFY
- Re-scan for secrets
- Verify fixes
- Install pre-commit hooks

Output:
- Security audit report
- Issues fixed
- Preventive measures in place

🐢 TURTLE — HARDEN

"Withdrawing to study the terrain..."

Phase: WITHDRAW
- Survey the attack surface
- Map all entry/exit points
- Catalog data flows
- Identify tech-stack-specific risks

Phase: LAYER
- Input validation (Zod schemas, allowlists)
- Output encoding (context-aware)
- Parameterized queries (zero concatenation)
- Type safety (strict mode, no 'any')
- Error handling (generic messages, no leaks)

Phase: FORTIFY
- Security headers (CSP, HSTS, X-Frame-Options, etc.)
- CORS strict configuration
- Session/cookie hardening
- CSRF enforcement
- Rate limiting
- Multi-tenant isolation
- File upload security
- Data protection (encryption, least privilege)

Phase: SIEGE
- Test for exotic attacks:
  Prototype pollution, timing attacks, race conditions,
  ReDoS, SSRF bypasses, CRLF injection, Unicode attacks,
  deserialization, postMessage vulns, WebSocket hijacking,
  CSS injection, SVG XSS, cache poisoning, HTTP verb
  tampering, second-order vulnerabilities, supply chain

Phase: SEAL
- Defense-in-depth compliance (2+ layers per critical function)
- Logging & monitoring verification
- Final scan for remaining issues
- Generate hardening report

Output:
- Defense-in-depth verified
- Exotic attack vectors tested
- Complete hardening report

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...
