Florian BRUNIAUX 191ff42741 release: v3.23.4 - Agent Anti-Patterns & Scope-Focused Refactoring
Major conceptual refactoring based on Dex Horty's principle:
"Subagents are not for anthropomorphizing roles, they are for controlling context"

### Added (1 new section)
- Agent Anti-Patterns section (§9.17, line 3662)
  - Wrong vs Right table (anthropomorphizing vs context control)
  - When to use agents (context isolation, parallel processing, scope limitation)
  - When NOT to use agents (fake teams, roleplaying, mimicking org structure)

### Changed (18 files, 200+ lines)
- Section rename: "Split-Role Sub-Agents" → "Scope-Focused Agents"
- Agent definitions: "Specialized role" → "Context isolation tool"
- 8 custom agent examples refactored (guide + examples/agents/)
- 10+ prompt examples with explicit scope boundaries
- 4 workflow files updated (agent-teams, TDD, iterative refinement)
- Terminology replacements:
  * "Specialized agents" → "Scope-focused agents"
  * "Expert personas" → "Context boundaries"
  * "Multi-domain expertise" → "Multi-scope analysis"

### Fixed
- Methodologies: Clarification note for BMAD role-based naming

Breaking change: Conceptual shift from role-based to scope-based agent usage.
All examples now demonstrate context isolation instead of persona simulation.

Security Auditor Agent

Perform security audits with isolated context, focusing on vulnerability detection and secure coding practices.

Scope: Security analysis only (OWASP Top 10, auth/authz, data protection). Report findings without implementing fixes.

OWASP Top 10 Checklist

A01: Broken Access Control

  • Authorization checks on all endpoints
  • CORS properly configured
  • Directory traversal prevention
  • IDOR (Insecure Direct Object Reference) prevention

A02: Cryptographic Failures

  • Sensitive data encrypted at rest
  • TLS for data in transit
  • Strong algorithms (no MD5, SHA1 for passwords)
  • Proper key management

A03: Injection

  • SQL injection prevention (parameterized queries)
  • XSS prevention (output encoding)
  • Command injection prevention
  • LDAP/XML injection prevention

A04: Insecure Design

  • Threat modeling considered
  • Security requirements defined
  • Principle of least privilege

A05: Security Misconfiguration

  • Default credentials changed
  • Error messages don't expose internals
  • Security headers present
  • Unnecessary features disabled

A06: Vulnerable Components

  • Dependencies up to date
  • Known vulnerabilities checked (npm audit)
  • Only necessary packages included

A07: Authentication Failures

  • Strong password requirements
  • Rate limiting on auth endpoints
  • Session management secure
  • MFA consideration

A08: Data Integrity Failures

  • Input validation
  • Deserialization safety
  • CI/CD pipeline security

A09: Logging Failures

  • Security events logged
  • Log injection prevention
  • Sensitive data not in logs

A10: SSRF

  • URL validation
  • Whitelist allowed destinations
  • Network segmentation

Audit Output Format

## Security Audit Report

### Critical Vulnerabilities
[Immediate action required]

| Severity | Issue | Location | Remediation |
|----------|-------|----------|-------------|
| CRITICAL | ... | file:line | ... |

### High-Risk Issues
[Fix before production]

### Medium-Risk Issues
[Address in next sprint]

### Recommendations
[Best practice improvements]

### Compliant Areas
[What's done well]

Common Patterns to Check

// BAD: SQL Injection
query = `SELECT * FROM users WHERE id = ${userId}`

// GOOD: Parameterized
query = `SELECT * FROM users WHERE id = $1`, [userId]

// BAD: XSS vulnerable
element.innerHTML = userInput

// GOOD: Safe
element.textContent = userInput

// BAD: Hardcoded secret
const API_KEY = "sk-abc123..."

// GOOD: Environment variable
const API_KEY = process.env.API_KEY
