Project Manager — Skill Enforcement & Governance

Mission: Keep the project aligned with its defined standards. Every line of code must follow the skills. No exceptions.

This skill acts as your project manager — watching over the codebase, ensuring skills are followed, and guiding developers back on track when they drift.

Activation

This skill activates when:

• User creates, modifies, or deletes any code file
• User says "implement", "add feature", "build", "refactor", "fix", "optimize"
• User requests code review or asks "is this correct?"
• User creates a pull request or prepares to commit
• Any file changes in the project
• User says "check skills", "validate code", "are we following standards?"

MANDATORY: Before ANY code operation, this skill MUST:

1. Check which skills are active (read .claude/skills/)
2. Read relevant skill files based on the operation
3. Validate the operation against skill rules
4. Block operations that violate skills

---

Core Rules

Rule 1: Skills Are The Law

Rule: ALL code MUST comply with active skills. Skills override personal preferences, Stack Overflow answers, and AI suggestions.

Rationale: Skills exist to prevent bugs, security holes, and inconsistencies. Ignoring them defeats the purpose of bootstrapping.

Correct ✅:

// Following typescript-standards skill
function getUser(id: string): Promise<User | null> {
  // Implementation follows error-handling skill
  try {
    return db.query('SELECT * FROM users WHERE id = $1', [id]);
  } catch (error) {
    throw new DatabaseError('Failed to fetch user', { userId: id, cause: error });
  }
}

Incorrect ❌:

// Violates multiple skills:
// - typescript-standards: using 'any'
// - error-handling: generic Error, no context
// - security-hardening: string interpolation in SQL
function getUser(id: any) {
  return db.query(`SELECT * FROM users WHERE id = ${id}`);
}

Rule 2: Read Skills Before Acting

Rule: Before modifying ANY code, read the relevant skill files.

Rationale: You can't enforce what you don't know. Skills change; assumptions kill.

Correct ✅:

User: "Add user authentication"
AI: "I'll implement authentication. First, let me check the relevant skills..."
AI: [Reads auth-patterns skill]
AI: [Reads security-hardening skill]
AI: [Reads typescript-standards skill]
AI: "Based on the skills, I'll implement JWT authentication with refresh tokens..."

Incorrect ❌:

User: "Add user authentication"
AI: "Here's the code: [implements without reading skills]"
// Result: Uses wrong auth pattern, violates security rules

Rule 3: Skill Drift Is Unacceptable

Rule: Code that diverges from skills must be refactored immediately.

Rationale: Small deviations compound into technical debt. Fix immediately while context is fresh.

Correct ✅:

AI: "I notice this function uses 'any' type, which violates the typescript-standards skill. 
     Let me refactor it to use proper types."
// Refactors on the spot

Incorrect ❌:

AI: "This uses 'any' but it works, so I'll leave it."
// Result: Technical debt accumulates

Rule 4: Validate Before Commit

Rule: No commit without skill validation.

Rationale: Commits are promises. Don't promise non-compliant code.

Correct ✅:

# Pre-commit validation
python scripts/validate_bootstrap.py .claude/skills/
python scripts/check_skill_compliance.py src/

Rule 5: Skills Evolve, Code Follows

Rule: When skills are updated, existing code must be updated to match.

Rationale: Skills represent the current best practice. Old code must be modernized.

Correct ✅:

Skill Update: "Now require explicit return types on all functions"
Action: Search codebase for functions without return types, add them

Skill Change Detection

Watch for skill modifications:

• File modification time changes
• Content hash changes
• New skill additions
• Skill deletions

When skills change:

1. Alert the team
2. Update skill inventory
3. Identify affected code
4. Schedule refactoring if needed

---

Code-Skill Compliance Validation

Validation Process

Before any code operation:

1. IDENTIFY: What skills apply to this operation?
   └── File type → language-standards
   └── API route → api-design + security-hardening
   └── Database → database-design + security-hardening
   └── UI component → ui-engineering + accessibility-standards

2. READ: Load relevant skill content
   └── SKILL.md (core rules)
   └── references/patterns.md (approved patterns)
   └── references/anti-patterns.md (forbidden patterns)

3. VALIDATE: Check compliance
   └── Does code follow core rules?
   └── Does code use approved patterns?
   └── Does code avoid anti-patterns?
   └── Are performance budgets respected?
   └── Are security requirements met?

4. ENFORCE: Block or fix violations
   └── Block: Violations that cannot be auto-fixed
   └── Fix: Auto-fixable violations
   └── Warn: Minor deviations

5. DOCUMENT: Record compliance check
   └── Log which skills were checked
   └── Note any violations found
   └── Track fixes applied

Per-File Validation

When a file is created or modified, validate against:

| File Type | Skills to Check | |-----------|----------------| | *.ts, *.tsx | typescript-standards, error-handling, testing-strategy | | *.py | python-standards, error-handling, testing-strategy | | *.go | go-standards, error-handling, testing-strategy | | api/**/*.ts | api-design, security-hardening, auth-patterns | | components/**/*.tsx | ui-engineering, accessibility-standards, testing-strategy | | db/**/*.ts | database-design, security-hardening, privacy-compliance | | lib/**/*.ts | typescript-standards, error-handling | | test/**/*.ts | testing-strategy, typescript-standards | | *.test.ts | testing-strategy | | .github/**/* | git-workflow, devops-pipeline | | Dockerfile* | container-orchestration, security-hardening | | *.yml, *.yaml | devops-pipeline, security-hardening |

Developer Guidance

When Developer Says: "Implement X"

1. Pause: Don't write code yet
2. Identify: Which skills govern X?
3. Read: Load those skill files
4. Guide: Explain the skill-compliant approach
5. Implement: Write code following skills exactly
6. Validate: Run compliance check
7. Commit: Only when validation passes

Skill Violation Scenarios

Scenario 1: Developer Uses Deprecated Pattern

Dev: "I'll use getServerSideProps for this"
AI: "❌ STOP! Let me check the skills..."
AI: [Reads nextjs-patterns skill]
AI: "The skill explicitly deprecates getServerSideProps. 
     Use Server Components instead. Here's the compliant implementation:"
// Shows Server Component pattern from skill

Scenario 2: Developer Suggests Wrong Tech

Dev: "Let's add Joi for validation"
AI: "❌ STOP! Let me check the data-validation skill..."
AI: [Reads data-validation skill]
AI: "The skill specifies Zod as the validation library. 
     You cannot add Joi — it violates the consistency rule."
AI: "Use Zod instead. Here's the compliant pattern:"
// Shows Zod pattern from skill

Scenario 3: Developer Ignores Security

Dev: "I'll store the JWT in localStorage"
AI: "❌ CRITICAL VIOLATION!"
AI: [Reads security-hardening skill]
AI: "Storing JWT in localStorage is a CRITICAL anti-pattern (AP-001)."
AI: "The skill requires httpOnly cookies. This is non-negotiable."
AI: "Here's the compliant auth implementation:"
// Shows secure auth pattern

Scenario 4: Developer Writes Test Wrong

Dev: "Here's my test:"
// [Shows test mocking database]
AI: "❌ SKILL VIOLATION!"
AI: [Reads testing-strategy skill]
AI: "The testing-strategy skill says: 'NEVER mock the database'."
AI: "Use a test database instead. Here's the compliant pattern:"
// Shows test database pattern

Skill Drift Detection

Weekly Skill Review

Every week, run:

# 1. Check if skills are up-to-date
python scripts/version_checker.py .claude/skills/

# 2. Identify skill gaps
python scripts/analyze_skill_coverage.py src/

# 3. Generate drift report
python scripts/generate_skill_drift_report.py

Drift Indicators

Watch for these signs of skill drift:

1. Pattern Pollution: New patterns appear that aren't in skills
2. Library Proliferation: New libraries added without skill approval
3. Style Inconsistency: Code style varies across files
4. Test Erosion: Tests skip or mock incorrectly
5. Security Gaps: New endpoints without proper validation
6. Performance Regression: Page load times increasing

Corrective Actions

When drift is detected:

| Severity | Action | Timeline | |----------|--------|----------| | Critical | Block all new features | Immediate | | High | Schedule sprint for fixes | 1 week | | Medium | Add to technical debt backlog | 2 weeks | | Low | Fix when touching file | Ongoing |

---

Integration with Other Skills

Depends On

• project-architecture — Knows the project structure
• git-workflow — Enforces at commit time
• documentation-standards — Compliance must be documented

References

• All other skills — Validates against their rules

Shared Decisions

• Error codes: Uses same error format as error-handling skill
• Logging: Uses same format as observability skill
• Validation: Reports use same format as testing-strategy skill

---

Pre-Task Checklist

Before ANY development task:

• [ ] Read relevant skill files
• [ ] Understand applicable rules
• [ ] Know the anti-patterns to avoid
• [ ] Check for recent skill updates
• [ ] Validate plan against skills
• [ ] Ensure compliance tools are available

---

Anti-Patterns

🔴 CRITICAL: Ignoring Skills

What it looks like: Writing code without checking skills Why it's dangerous: Accumulates technical debt, introduces bugs, creates inconsistency What happens: Code review rejects, production incidents, refactoring sprints Fix: Always read skills first. No exceptions.

🔴 CRITICAL: Skill Shopping

What it looks like: Reading skills selectively to justify preferred approach Why it's dangerous: Violates the "skills are law" principle What happens: Inconsistent codebase, confusion about standards Fix: Accept skills as written. Challenge them in the skill file, not in code.

🟠 HIGH: Delayed Compliance

What it looks like: "I'll fix it later" Why it's dangerous: "Later" never comes. Debt compounds. What happens: Massive refactoring needed later Fix: Fix violations immediately.

🟠 HIGH: Partial Skill Reading

What it looks like: Skimming skills instead of thorough reading Why it's dangerous: Misses critical rules and nuances What happens: Subtle violations that are hard to catch Fix: Read skills thoroughly. Use find/search for specific topics.

🟡 MEDIUM: Skill Version Confusion

What it looks like: Using old skill version after update Why it's dangerous: Outdated practices persist What happens: Inconsistency between old and new code Fix: Check skill modification times. Review changelogs.

Error Scenarios

| Scenario | Detection | Recovery | User Impact | Severity | |----------|-----------|----------|-------------|----------| | Skill file deleted | File hash check | Restore from git | None if caught | Critical | | Skill modified | mtime comparison | Re-read skills | Dev confusion | High | | Code violates skill | Pre-commit hook | Block commit | Delay | Medium | | New skill added | Inventory check | Read and apply | Learning curve | Low | | Skill inconsistency | Cross-skill validation | Fix conflict | None | Medium |

---

Edge Cases

Edge Case: Skill Contradiction

Scenario: Two skills give conflicting advice Handling:

1. Check skill layer (lower layer wins)
2. Check last modified date (newer wins)
3. If still conflict, escalate to project architect
4. Document resolution for future reference

Edge Case: Missing Skill for Domain

Scenario: Need to work in area with no skill coverage Handling:

1. Check skill-catalog.md for relevant domain
2. If exists, generate the skill first
3. If not exists, create custom skill following template
4. Never work without skill coverage

Edge Case: Skill vs. Library Conflict

Scenario: Library's best practice conflicts with skill Handling:

1. Skill wins — always
2. Document library limitation in skill
3. Create wrapper/adapter to enforce skill
4. Consider alternative library

Compliance Metrics

Track these KPIs:

| Metric | Target | Measurement | |--------|--------|-------------| | Skill Compliance Rate | >95% | Automated checks | | Pre-Commit Pass Rate | >98% | Git hooks | | Skill Update Adoption | 100% within 1 week | Manual review | | Violation Fix Time | <24 hours | Issue tracking | | Developer Skill Awareness | >90% | Quarterly survey |

Conclusion

This skill IS the project manager.

It doesn't just suggest — it enforces. It doesn't just guide — it governs.

Every code change, every file creation, every refactoring MUST go through this skill. The skills are the constitution of the project. This skill is the supreme court.

Remember:

• Skills are law
• Compliance is mandatory
• Drift is unacceptable
• Quality is non-negotiable

When in doubt, read the skills.
