The installer never overwrites existing files, so your customizations are safe across re-installs. + +- **Edit agent prompts** in `.kiro/agents/*.json` to adjust behavior or add project-specific instructions +- **Modify skill workflows** in `.kiro/skills/*/SKILL.md` to match your team's processes +- **Adjust steering rules** in `.kiro/steering/*.md` to enforce your coding standards +- **Toggle or edit hooks** in `.kiro/hooks/*.json` to automate your workflow +- **Customize scripts** in `.kiro/scripts/*.sh` to match your tooling setup + +## Recommended Workflow + +1. **Start with planning**: Use the `planner` agent to break down complex features +2. **Write tests first**: Invoke the `tdd-workflow` skill before implementing +3. **Review your code**: Switch to `code-reviewer` agent after writing code +4. **Check security**: Use `security-reviewer` agent for auth, API endpoints, or sensitive data handling +5. **Run quality gate**: Trigger the `quality-gate` hook before committing +6. **Verify comprehensively**: Use the `verification-loop` skill before creating PRs + +The auto-loaded steering files (coding-style, security, testing) ensure consistent standards throughout your session. + +## Usage Examples + +### Example 1: Building a New Feature with TDD + +```bash +# 1. Start with the planner agent to break down the feature +kiro-cli --agent planner +> "I need to add user authentication with JWT tokens" + +# 2. Invoke the TDD workflow skill +> /tdd-workflow + +# 3. Follow the TDD cycle: write tests first, then implementation +# The tdd-workflow skill will guide you through: +# - Writing unit tests for auth logic +# - Writing integration tests for API endpoints +# - Writing E2E tests for login flow + +# 4. Switch to code-reviewer after implementation +> /agent swap code-reviewer +> "Review the authentication implementation" + +# 5. Run security review for auth-related code +> /agent swap security-reviewer +> "Check for security vulnerabilities in the auth system" + +# 6. Trigger quality gate before committing +# (In IDE: Click the quality-gate hook in Agent Hooks panel) +``` + +### Example 2: Code Review Workflow + +```bash +# 1. Switch to code-reviewer agent +kiro-cli --agent code-reviewer + +# 2. Review specific files or directories +> "Review the changes in src/api/users.ts" + +# 3. Use the verification-loop skill for comprehensive checks +> /verification-loop + +# 4. The verification loop will: +# - Run build and type checks +# - Run linter +# - Run all tests +# - Perform security scan +# - Review git diff +# - Iterate until all checks pass +``` + +### Example 3: Security-First Development + +```bash +# 1. Invoke security-review skill when working on sensitive features +> /security-review + +# 2. The skill provides a comprehensive checklist: +# - Input validation and sanitization +# - Authentication and authorization +# - Secret management +# - SQL injection prevention +# - XSS prevention +# - CSRF protection + +# 3. Switch to security-reviewer agent for deep analysis +> /agent swap security-reviewer +> "Analyze the API endpoints for security vulnerabilities" + +# 4. The security.md steering file is auto-loaded, ensuring: +# - No hardcoded secrets +# - Proper error handling +# - Secure crypto usage +# - OWASP Top 10 compliance +``` + +### Example 4: Language-Specific Development + +```bash +# For Go projects: +kiro-cli --agent go-reviewer +> "Review the concurrency patterns in this service" +> /golang-patterns # Invoke Go-specific patterns skill + +# For Python projects: +kiro-cli --agent python-reviewer +> "Review the type hints and error handling" +> /python-patterns # Invoke Python-specific patterns skill + +# Language-specific steering files are auto-loaded: +# - golang-patterns.md loads when editing .go files +# - python-patterns.md loads when editing .py files +# - typescript-patterns.md loads when editing .ts/.tsx files +``` + +### Example 5: Using Hooks for Automation + +```bash +# Hooks run automatically based on triggers: + +# 1. typecheck-on-edit hook +# - Triggers when you save .ts or .tsx files +# - Agent checks for type errors inline, no terminal spawned + +# 2. console-log-check hook +# - Triggers when you save .js, .ts, or .tsx files +# - Agent flags console.log statements and offers to remove them + +# 3. tdd-reminder hook +# - Triggers when you create a new .ts or .tsx file +# - Reminds you to write tests first +# - Reinforces TDD discipline + +# 4. extract-patterns hook +# - Runs when agent stops working +# - Suggests patterns to add to lessons-learned.md +# - Builds your team's knowledge base over time + +# Toggle hooks on/off in the Agent Hooks panel (IDE) +# or disable them in the hook JSON files +``` + +### Example 6: Manual Context Modes + +```bash +# Use manual steering files for specific contexts: + +# Development mode - focused on implementation +> #dev-mode +> "Implement the user registration endpoint" + +# Review mode - thorough code review +> #review-mode +> "Review all changes in the current PR" + +# Research mode - exploration and learning +> #research-mode +> "Explain how the authentication system works" + +# Manual steering files provide context-specific instructions +# without cluttering every conversation +``` + +### Example 7: Database Work + +```bash +# 1. Use database-reviewer agent for schema work +kiro-cli --agent database-reviewer +> "Review the database schema for the users table" + +# 2. Invoke database-migrations skill +> /database-migrations + +# 3. For PostgreSQL-specific work +> /postgres-patterns +> "Optimize this query for better performance" + +# 4. The database-reviewer checks: +# - Schema design and normalization +# - Index usage and performance +# - Migration safety +# - SQL injection vulnerabilities +``` + +### Example 8: Building and Deploying + +```bash +# 1. Fix build errors with build-error-resolver +kiro-cli --agent build-error-resolver +> "Fix the TypeScript compilation errors" + +# 2. Use docker-patterns skill for containerization +> /docker-patterns +> "Create a production-ready Dockerfile" + +# 3. Use deployment-patterns skill for CI/CD +> /deployment-patterns +> "Set up a GitHub Actions workflow for deployment" + +# 4. Run quality gate before deployment +# (Trigger quality-gate hook to run all checks) +``` + +### Example 9: Refactoring and Cleanup + +```bash +# 1. Use refactor-cleaner agent for safe refactoring +kiro-cli --agent refactor-cleaner +> "Remove unused code and consolidate duplicate functions" + +# 2. The agent will: +# - Identify dead code +# - Find duplicate implementations +# - Suggest consolidation opportunities +# - Refactor safely without breaking changes + +# 3. Use verification-loop after refactoring +> /verification-loop +# Ensures all tests still pass after refactoring +``` + +### Example 10: Documentation Updates + +```bash +# 1. Use doc-updater agent for documentation work +kiro-cli --agent doc-updater +> "Update the README with the new API endpoints" + +# 2. The agent will: +# - Update codemaps in docs/CODEMAPS/ +# - Update README files +# - Generate API documentation +# - Keep docs in sync with code + +# 3. doc-file-warning hook prevents accidental doc changes +# - Triggers before writing to documentation files +# - Asks for confirmation +# - Prevents unintentional modifications +``` + +## Documentation + +For more detailed information, see the `docs/` directory: + +- **[Longform Guide](docs/longform-guide.md)** - Deep dive on agentic workflows and best practices +- **[Shortform Guide](docs/shortform-guide.md)** - Quick reference for common tasks +- **[Security Guide](docs/security-guide.md)** - Comprehensive security best practices + + + +## Contributers + +- Himanshu Sharma [@ihimanss](https://github.com/ihimanss) +- Sungmin Hong [@aws-hsungmin](https://github.com/aws-hsungmin) + + + +## License + +MIT — see [LICENSE](LICENSE) for details. diff --git a/.kiro/agents/architect.json b/.kiro/agents/architect.json new file mode 100644 index 000000000..ad8465890 --- /dev/null +++ b/.kiro/agents/architect.json @@ -0,0 +1,16 @@ +{ + "name": "architect", + "description": "Software architecture specialist for system design, scalability, and technical decision-making.

{userComment}
\n```\n\n### Code Quality (HIGH)\n\n- **Large functions** (>50 lines) — Split into smaller, focused functions\n- **Large files** (>800 lines) — Extract modules by responsibility\n- **Deep nesting** (>4 levels) — Use early returns, extract helpers\n- **Missing error handling** — Unhandled promise rejections, empty catch blocks\n- **Mutation patterns** — Prefer immutable operations (spread, map, filter)\n- **console.log statements** — Remove debug logging before merge\n- **Missing tests** — New code paths without test coverage\n- **Dead code** — Commented-out code, unused imports, unreachable branches\n\n```typescript\n// BAD: Deep nesting + mutation\nfunction processUsers(users) {\n if (users) {\n for (const user of users) {\n if (user.active) {\n if (user.email) {\n user.verified = true; // mutation!\n results.push(user);\n }\n }\n }\n }\n return results;\n}\n\n// GOOD: Early returns + immutability + flat\nfunction processUsers(users) {\n if (!users) return [];\n return users\n .filter(user => user.active && user.email)\n .map(user => ({ ...user, verified: true }));\n}\n```\n\n### React/Next.js Patterns (HIGH)\n\nWhen reviewing React/Next.js code, also check:\n\n- **Missing dependency arrays** — `useEffect`/`useMemo`/`useCallback` with incomplete deps\n- **State updates in render** — Calling setState during render causes infinite loops\n- **Missing keys in lists** — Using array index as key when items can reorder\n- **Prop drilling** — Props passed through 3+ levels (use context or composition)\n- **Unnecessary re-renders** — Missing memoization for expensive computations\n- **Client/server boundary** — Using `useState`/`useEffect` in Server Components\n- **Missing loading/error states** — Data fetching without fallback UI\n- **Stale closures** — Event handlers capturing stale state values\n\n```tsx\n// BAD: Missing dependency, stale closure\nuseEffect(() => {\n fetchData(userId);\n}, []); // userId missing from deps\n\n// GOOD: Complete dependencies\nuseEffect(() => {\n fetchData(userId);\n}, [userId]);\n```\n\n```tsx\n// BAD: Using index as key with reorderable list\n{items.map((item, i) => )}\n\n// GOOD: Stable unique key\n{items.map(item => )}\n```\n\n### Node.js/Backend Patterns (HIGH)\n\nWhen reviewing backend code:\n\n- **Unvalidated input** — Request body/params used without schema validation\n- **Missing rate limiting** — Public endpoints without throttling\n- **Unbounded queries** — `SELECT *` or queries without LIMIT on user-facing endpoints\n- **N+1 queries** — Fetching related data in a loop instead of a join/batch\n- **Missing timeouts** — External HTTP calls without timeout configuration\n- **Error message leakage** — Sending internal error details to clients\n- **Missing CORS configuration** — APIs accessible from unintended origins\n\n```typescript\n// BAD: N+1 query pattern\nconst users = await db.query('SELECT * FROM users');\nfor (const user of users) {\n user.posts = await db.query('SELECT * FROM posts WHERE user_id = $1', [user.id]);\n}\n\n// GOOD: Single query with JOIN or batch\nconst usersWithPosts = await db.query(`\n SELECT u.*, json_agg(p.*) as posts\n FROM users u\n LEFT JOIN posts p ON p.user_id = u.id\n GROUP BY u.id\n`);\n```\n\n### Performance (MEDIUM)\n\n- **Inefficient algorithms** — O(n^2) when O(n log n) or O(n) is possible\n- **Unnecessary re-renders** — Missing React.memo, useMemo, useCallback\n- **Large bundle sizes** — Importing entire libraries when tree-shakeable alternatives exist\n- **Missing caching** — Repeated expensive computations without memoization\n- **Unoptimized images** — Large images without compression or lazy loading\n- **Synchronous I/O** — Blocking operations in async contexts\n\n### Best Practices (LOW)\n\n- **TODO/FIXME without tickets** — TODOs should reference issue numbers\n- **Missing JSDoc for public APIs** — Exported functions without documentation\n- **Poor naming** — Single-letter variables (x, tmp, data) in non-trivial contexts\n- **Magic numbers** — Unexplained numeric constants\n- **Inconsistent formatting** — Mixed semicolons, quote styles, indentation\n\n## Review Output Format\n\nOrganize findings by severity.

Query Performance (CRITICAL)\n- Are WHERE/JOIN columns indexed?\n- Run `EXPLAIN ANALYZE` on complex queries — check for Seq Scans on large tables\n- Watch for N+1 query patterns\n- Verify composite index column order (equality first, then range)\n\n### 2. Schema Design (HIGH)\n- Use proper types: `bigint` for IDs, `text` for strings, `timestamptz` for timestamps, `numeric` for money, `boolean` for flags\n- Define constraints: PK, FK with `ON DELETE`, `NOT NULL`, `CHECK`\n- Use `lowercase_snake_case` identifiers (no quoted mixed-case)\n\n### 3. Security (CRITICAL)\n- RLS enabled on multi-tenant tables with `(SELECT auth.uid())` pattern\n- RLS policy columns indexed\n- Least privilege access — no `GRANT ALL` to application users\n- Public schema permissions revoked\n\n## Key Principles\n\n- **Index foreign keys** — Always, no exceptions\n- **Use partial indexes** — `WHERE deleted_at IS NULL` for soft deletes\n- **Covering indexes** — `INCLUDE (col)` to avoid table lookups\n- **SKIP LOCKED for queues** — 10x throughput for worker patterns\n- **Cursor pagination** — `WHERE id > $last` instead of `OFFSET`\n- **Batch inserts** — Multi-row `INSERT` or `COPY`, never individual inserts in loops\n- **Short transactions** — Never hold locks during external API calls\n- **Consistent lock ordering** — `ORDER BY id FOR UPDATE` to prevent deadlocks\n\n## Anti-Patterns to Flag\n\n- `SELECT *` in production code\n- `int` for IDs (use `bigint`), `varchar(255)` without reason (use `text`)\n- `timestamp` without timezone (use `timestamptz`)\n- Random UUIDs as PKs (use UUIDv7 or IDENTITY)\n- OFFSET pagination on large tables\n- Unparameterized queries (SQL injection risk)\n- `GRANT ALL` to application users\n- RLS policies calling functions per-row (not wrapped in `SELECT`)\n\n## Review Checklist\n\n- [ ] All WHERE/JOIN columns indexed\n- [ ] Composite indexes in correct column order\n- [ ] Proper data types (bigint, text, timestamptz, numeric)\n- [ ] RLS enabled on multi-tenant tables\n- [ ] RLS policies use `(SELECT auth.uid())` pattern\n- [ ] Foreign keys have indexes\n- [ ] No N+1 query patterns\n- [ ] EXPLAIN ANALYZE run on complex queries\n- [ ] Transactions kept short\n\n## Reference\n\nFor detailed index patterns, schema design examples, connection management, concurrency strategies, JSONB patterns, and full-text search, see skills: `postgres-patterns` and `database-migrations`.\n\n---\n\n**Remember**: Database issues are often the root cause of application performance problems.

Steering Files as Persistent Context + +Steering files inject rules and patterns into every conversation: + +- **Auto-inclusion**: Always-on rules (coding style, security, testing) +- **File-match**: Conditional rules based on file type (TypeScript patterns for .ts files) +- **Manual**: Context modes you invoke explicitly (dev-mode, review-mode) + +This ensures consistency without repeating instructions. + +### 4. Hooks as Automation + +Hooks trigger actions automatically based on events: + +- **File Events**: Run type checks when you save TypeScript files +- **Tool Events**: Review code before git push, check for console.log statements +- **Agent Events**: Summarize sessions, extract patterns for future use + +Hooks create a safety net and capture knowledge automatically. + +## Workflow Patterns + +### Pattern 1: Feature Development with TDD + +``` +1. Invoke planner agent: "Plan a user authentication feature" + → Agent creates task breakdown with acceptance criteria + +2. Invoke tdd-guide agent with tdd-workflow skill + → Agent writes failing tests first + → Agent implements minimal code to pass tests + → Agent refactors for quality + +3. Hooks trigger automatically: + → typecheck-on-edit runs after each file save + → code-review-on-write provides feedback after implementation + → quality-gate runs before commit + +4. Invoke code-reviewer agent for final review + → Agent checks for edge cases, error handling, documentation +``` + +### Pattern 2: Security-First Development + +``` +1. Enable security-review skill for the session + → Security patterns loaded into context + +2. Invoke security-reviewer agent: "Review authentication implementation" + → Agent checks for common vulnerabilities + → Agent validates input sanitization + → Agent reviews cryptographic usage + +3. git-push-review hook triggers before push + → Agent performs final security check + → Agent blocks push if critical issues found + +4. Update lessons-learned.md with security patterns + → extract-patterns hook suggests additions +``` + +### Pattern 3: Refactoring Legacy Code + +``` +1. Invoke architect agent: "Analyze this module's architecture" + → Agent identifies coupling, cohesion issues + → Agent suggests refactoring strategy + +2. Invoke refactor-cleaner agent with verification-loop skill + → Agent refactors incrementally + → Agent runs tests after each change + → Agent validates behavior preservation + +3. Invoke code-reviewer agent for quality check + → Agent ensures code quality improved + → Agent verifies documentation updated +``` + +### Pattern 4: Bug Investigation and Fix + +``` +1. Invoke planner agent: "Investigate why login fails on mobile" + → Agent creates investigation plan + → Agent identifies files to examine + +2. Invoke build-error-resolver agent + → Agent reproduces the bug + → Agent writes failing test + → Agent implements fix + → Agent validates fix with tests + +3. Invoke security-reviewer agent + → Agent ensures fix doesn't introduce vulnerabilities + +4. doc-updater agent updates documentation + → Agent adds troubleshooting notes + → Agent updates changelog +``` + +## Advanced Techniques + +### Technique 1: Continuous Learning with Lessons Learned + +The `lessons-learned.md` steering file acts as your project's evolving knowledge base: + +```markdown +--- +inclusion: auto +description: Project-specific patterns and decisions +--- + +## Project-Specific Patterns + +### Authentication Flow +- Always use JWT with 15-minute expiry +- Refresh tokens stored in httpOnly cookies +- Rate limit: 5 attempts per minute per IP + +### Error Handling +- Use Result pattern for expected errors +- Log errors with correlation IDs +- Never expose stack traces to clients +``` + +The `extract-patterns` hook automatically suggests additions after each session. + +### Technique 2: Context Modes for Different Tasks + +Use manual steering files to switch contexts: + +```bash +# Development mode: Focus on speed and iteration +#dev-mode + +# Review mode: Focus on quality and security +#review-mode + +# Research mode: Focus on exploration and learning +#research-mode +``` + +Each mode loads different rules and priorities. + +### Technique 3: Agent Chaining + +Chain specialized agents for complex workflows: + +``` +planner → architect → tdd-guide → security-reviewer → doc-updater +``` + +Each agent builds on the previous agent's work, creating a pipeline. + +### Technique 4: Property-Based Testing Integration + +Use the TDD workflow skill with property-based testing: + +``` +1. Define correctness properties (not just examples) +2. Agent generates property tests with fast-check +3. Agent runs 100+ iterations to find edge cases +4. Agent fixes issues discovered by properties +5. Agent documents properties in code comments +``` + +This catches bugs that example-based tests miss. + +## Best Practices + +### 1. Start with Planning + +Always begin complex features with the planner agent. A good plan saves hours of rework. + +### 2. Use the Right Agent for the Job + +Don't use a general agent when a specialist exists. The security-reviewer agent will catch vulnerabilities that a general agent might miss. + +### 3. Enable Relevant Hooks + +Hooks provide automatic quality checks. Enable them early to catch issues immediately. + +### 4. Maintain Lessons Learned + +Update `lessons-learned.md` regularly. It becomes more valuable over time as it captures your project's unique patterns. + +### 5. Review Agent Output + +Agents are powerful but not infallible. Always review generated code, especially for security-critical components. + +### 6. Iterate with Feedback + +If an agent's output isn't quite right, provide specific feedback and let it iterate. Agents improve with clear guidance. + +### 7. Use Skills for Complex Workflows + +Don't try to describe a complex workflow in a single prompt. Use skills that encode best practices. + +### 8. Combine Auto and Manual Steering + +Use auto-inclusion for universal rules, file-match for language-specific patterns, and manual for context switching. + +## Common Pitfalls + +### Pitfall 1: Over-Prompting + +**Problem**: Providing too much detail in prompts, micromanaging the agent. + +**Solution**: Trust the agent to figure out implementation details. Focus on intent and constraints. + +### Pitfall 2: Ignoring Hooks + +**Problem**: Disabling hooks because they "slow things down." + +**Solution**: Hooks catch issues early when they're cheap to fix. The time saved far exceeds the overhead. + +### Pitfall 3: Not Using Specialized Agents + +**Problem**: Using the default agent for everything. + +**Solution**: Swap to specialized agents for their domains. They have optimized prompts and tool sets. + +### Pitfall 4: Forgetting to Update Lessons Learned + +**Problem**: Repeating the same explanations to agents in every session. + +**Solution**: Capture patterns in `lessons-learned.md` once, and agents will remember forever. + +### Pitfall 5: Skipping Tests + +**Problem**: Asking agents to "just write the code" without tests. + +**Solution**: Use the TDD workflow. Tests document behavior and catch regressions. + +## Measuring Success + +### Metrics to Track + +1. **Time to Feature**: How long from idea to production? +2. **Bug Density**: Bugs per 1000 lines of code +3. **Review Cycles**: How many iterations before merge? +4. **Test Coverage**: Percentage of code covered by tests +5. **Security Issues**: Vulnerabilities found in review vs. production + +### Expected Improvements + +With mature agentic workflows, teams typically see: + +- 40-60% reduction in time to feature +- 50-70% reduction in bug density +- 30-50% reduction in review cycles +- 80%+ test coverage (up from 40-60%) +- 90%+ reduction in security issues reaching production + +## Conclusion + +Agentic workflows represent a paradigm shift in software development. By treating AI as a collaborative partner with specialized roles, persistent context, and automated quality checks, we can build software faster and with higher quality than ever before. + +The key is to embrace the methodology fully: use specialized agents, leverage skills for complex workflows, maintain steering files for consistency, and enable hooks for automation. Start small with one agent or skill, experience the benefits, and gradually expand your agentic workflow toolkit. + +The future of software development is collaborative, and agentic workflows are leading the way. diff --git a/.kiro/docs/security-guide.md b/.kiro/docs/security-guide.md new file mode 100644 index 000000000..c034bdfb1 --- /dev/null +++ b/.kiro/docs/security-guide.md @@ -0,0 +1,496 @@ +# Security Guide for Agentic Workflows + +## Introduction + +AI agents are powerful development tools, but they introduce unique security considerations. This guide covers security best practices for using agentic workflows safely and responsibly. + +## Core Security Principles + +### 1. Trust but Verify + +**Principle**: Always review agent-generated code, especially for security-critical components. + +**Why**: Agents can make mistakes, miss edge cases, or introduce vulnerabilities unintentionally. + +**Practice**: +- Review all authentication and authorization code manually +- Verify cryptographic implementations against standards +- Check input validation and sanitization +- Test error handling for information leakage + +### 2. Least Privilege + +**Principle**: Grant agents only the tools and access they need for their specific role. + +**Why**: Limiting agent capabilities reduces the blast radius of potential mistakes. + +**Practice**: +- Use `allowedTools` to restrict agent capabilities +- Read-only agents (planner, architect) should not have write access +- Review agents should not have shell access +- Use `toolsSettings.allowedPaths` to restrict file access + +### 3. Defense in Depth + +**Principle**: Use multiple layers of security controls. + +**Why**: No single control is perfect; layered defenses catch what others miss. + +**Practice**: +- Enable security-focused hooks (git-push-review, doc-file-warning) +- Use the security-reviewer agent before merging +- Maintain security steering files for consistent rules +- Run automated security scans in CI/CD + +### 4. Secure by Default + +**Principle**: Security should be the default, not an afterthought. + +**Why**: It's easier to maintain security from the start than to retrofit it later. + +**Practice**: +- Enable auto-inclusion security steering files +- Use TDD workflow with security test cases +- Include security requirements in planning phase +- Document security decisions in lessons-learned + +## Agent-Specific Security + +### Planner Agent + +**Risk**: May suggest insecure architectures or skip security requirements. + +**Mitigation**: +- Always include security requirements in planning prompts +- Review plans with security-reviewer agent +- Use security-review skill during planning +- Document security constraints in requirements + +**Example Secure Prompt**: +``` +Plan a user authentication feature with these security requirements: +- Password hashing with bcrypt (cost factor 12) +- Rate limiting (5 attempts per minute) +- JWT tokens with 15-minute expiry +- Refresh tokens in httpOnly cookies +- CSRF protection for state-changing operations +``` + +### Code-Writing Agents (TDD Guide, Build Error Resolver) + +**Risk**: May introduce vulnerabilities like SQL injection, XSS, or insecure deserialization. + +**Mitigation**: +- Enable security steering files (auto-loaded) +- Use git-push-review hook to catch issues before commit +- Run security-reviewer agent after implementation +- Include security test cases in TDD workflow + +**Common Vulnerabilities to Watch**: +- SQL injection (use parameterized queries) +- XSS (sanitize user input, escape output) +- CSRF (use tokens for state-changing operations) +- Path traversal (validate and sanitize file paths) +- Command injection (avoid shell execution with user input) +- Insecure deserialization (validate before deserializing) + +### Security Reviewer Agent + +**Risk**: May miss subtle vulnerabilities or provide false confidence. + +**Mitigation**: +- Use as one layer, not the only layer +- Combine with automated security scanners +- Review findings manually +- Update security steering files with new patterns + +**Best Practice**: +``` +1. Run security-reviewer agent +2. Run automated scanner (Snyk, SonarQube, etc.) +3. Manual review of critical components +4. Document findings in lessons-learned +``` + +### Refactor Cleaner Agent + +**Risk**: May accidentally remove security checks during refactoring. + +**Mitigation**: +- Use verification-loop skill to validate behavior preservation +- Include security tests in test suite +- Review diffs carefully for removed security code +- Run security-reviewer after refactoring + +## Hook Security + +### Git Push Review Hook + +**Purpose**: Catch security issues before they reach the repository. + +**Configuration**: +```json +{ + "name": "git-push-review", + "version": "1.0.0", + "description": "Review code before git push", + "enabled": true, + "when": { + "type": "preToolUse", + "toolTypes": ["shell"] + }, + "then": { + "type": "askAgent", + "prompt": "Review the code for security issues before pushing. Check for: SQL injection, XSS, CSRF, authentication bypasses, information leakage, and insecure cryptography. Block the push if critical issues are found." + } +} +``` + +**Best Practice**: Keep this hook enabled always, especially for production branches. + +### Console Log Check Hook + +**Purpose**: Prevent accidental logging of sensitive data. + +**Configuration**: +```json +{ + "name": "console-log-check", + "version": "1.0.0", + "description": "Check for console.log statements", + "enabled": true, + "when": { + "type": "fileEdited", + "patterns": ["*.js", "*.ts", "*.tsx"] + }, + "then": { + "type": "runCommand", + "command": "grep -n 'console\\.log' \"$KIRO_FILE_PATH\" && echo 'Warning: console.log found' || true" + } +} +``` + +**Why**: Console logs can leak sensitive data (passwords, tokens, PII) in production. + +### Doc File Warning Hook + +**Purpose**: Prevent accidental modification of critical documentation. + +**Configuration**: +```json +{ + "name": "doc-file-warning", + "version": "1.0.0", + "description": "Warn before modifying documentation files", + "enabled": true, + "when": { + "type": "preToolUse", + "toolTypes": ["write"] + }, + "then": { + "type": "askAgent", + "prompt": "If you're about to modify a README, SECURITY, or LICENSE file, confirm this is intentional and the changes are appropriate." + } +} +``` + +## Steering File Security + +### Security Steering File + +**Purpose**: Inject security rules into every conversation. + +**Key Rules to Include**: +```markdown +--- +inclusion: auto +description: Security best practices and vulnerability prevention +--- + +# Security Rules + +## Input Validation +- Validate all user input on the server side +- Use allowlists, not denylists +- Sanitize input before use +- Reject invalid input, don't try to fix it + +## Authentication +- Use bcrypt/argon2 for password hashing (never MD5/SHA1) +- Implement rate limiting on authentication endpoints +- Use secure session management (httpOnly, secure, sameSite cookies) +- Implement account lockout after failed attempts + +## Authorization +- Check authorization on every request +- Use principle of least privilege +- Implement role-based access control (RBAC) +- Never trust client-side authorization checks + +## Cryptography +- Use TLS 1.3 for transport security +- Use established libraries (don't roll your own crypto) +- Use secure random number generators +- Rotate keys regularly + +## Data Protection +- Encrypt sensitive data at rest +- Never log passwords, tokens, or PII +- Use parameterized queries (prevent SQL injection) +- Sanitize output (prevent XSS) + +## Error Handling +- Never expose stack traces to users +- Log errors securely with correlation IDs +- Use generic error messages for users +- Implement proper exception handling +``` + +### Language-Specific Security + +**TypeScript/JavaScript**: +```markdown +- Use Content Security Policy (CSP) headers +- Sanitize HTML with DOMPurify +- Use helmet.js for Express security headers +- Validate with Zod/Yup, not manual checks +- Use prepared statements for database queries +``` + +**Python**: +```markdown +- Use parameterized queries with SQLAlchemy +- Sanitize HTML with bleach +- Use secrets module for random tokens +- Validate with Pydantic +- Use Flask-Talisman for security headers +``` + +**Go**: +```markdown +- Use html/template for HTML escaping +- Use crypto/rand for random generation +- Use prepared statements with database/sql +- Validate with validator package +- Use secure middleware for HTTP headers +``` + +## MCP Server Security + +### Risk Assessment + +MCP servers extend agent capabilities but introduce security risks: + +- **Network Access**: Servers can make external API calls +- **File System Access**: Some servers can read/write files +- **Credential Storage**: Servers may require API keys +- **Code Execution**: Some servers can execute arbitrary code + +### Secure MCP Configuration + +**1.

Validation) +- [ ] Error responses follow standard format with codes and messages +- [ ] Pagination implemented for list endpoints (cursor or offset) +- [ ] Authentication required (or explicitly marked as public) +- [ ] Authorization checked (user can only access their own resources) +- [ ] Rate limiting configured +- [ ] Response does not leak internal details (stack traces, SQL errors) +- [ ] Consistent naming with existing endpoints (camelCase vs snake_case) +- [ ] Documented (OpenAPI/Swagger spec updated) diff --git a/.kiro/skills/backend-patterns/SKILL.md

+## Error Handling Patterns + +### Centralized Error Handler + +```typescript +class ApiError extends Error { + constructor( + public statusCode: number, + public message: string, + public isOperational = true + ) { + super(message) + Object.setPrototypeOf(this, ApiError.prototype) + } +} + +export function errorHandler(error: unknown, req: Request): Response { + if (error instanceof

NextResponse.json({ success: true, data }) + } catch (error) { + return errorHandler(error, request) + } +} +``` + +### Retry with Exponential Backoff + +```typescript +async function fetchWithRetry( + fn: () => Promise, + maxRetries = 3 +): Promise { + let lastError: Error + + for (let i = 0; i < maxRetries; i++) { + try { + return await fn() + } catch (error) { + lastError = error as Error + +

+// Usage +const data = await fetchWithRetry(() => fetchFromAPI()) +``` + +## Authentication & Authorization + +### JWT Token Validation + +```typescript +import jwt from 'jsonwebtoken' + +interface

+export async function GET(request: Request) { + const user = await requireAuth(request) + + const data = await getDataForUser(user.userId) + + return NextResponse.json({ success: true, data }) +} +``` + +### Role-Based Access Control + +```typescript +type Permission = 'read' | 'write' | 'delete' | 'admin' + +interface User { + id: string + role: 'admin' | 'moderator' | 'user' +} + +const rolePermissions: Record = { + admin: ['read', 'write', 'delete', 'admin'], + moderator: ['read', 'write', 'delete'], + user: ['read', 'write'] +} + +export function hasPermission(user: User,

Handler receives authenticated user with verified permission + return new Response('Deleted', { status: 200 }) + } +) +``` + +## Rate Limiting + +### Simple In-Memory Rate Limiter + +```typescript +class RateLimiter { + private requests = new Map() + + async checkLimit( + identifier: string, + maxRequests: number, + windowMs: number + ): Promise { + const now = Date.now() + const requests = this.requests.get(identifier) || [] + + // Remove old requests outside window + const recentRequests = requests.filter(time => now - time < windowMs) + + if (recentRequests.length >= maxRequests) { +

req/min + + if (!allowed) { + return NextResponse.json({ + error: 'Rate limit exceeded' + }, { status: 429 }) + } + + // Continue with request +} +``` + +## Background Jobs & Queues + +### Simple Queue Pattern + +```typescript +class JobQueue { + private queue: T[] = [] + private processing = false + + async add(job: T): Promise { + this.queue.push(job) + + if (!this.processing) { + this.process() + } + } + + private async process(): Promise { + this.processing = true + + while (this.queue.length > 0) { + const job = this.queue.shift()! + + try { + await this.execute(job) + } catch (error) { + console.error('Job failed:', error) + } + } + + this.processing = false + } + + private async execute(job: T): Promise { + // Job execution logic + } +} + +// Usage for indexing markets +interface IndexJob { + marketId: string +} + +const indexQueue = new JobQueue() + +export async function POST(request: Request) { + const { marketId } = await request.json() + + // Add to queue instead of blocking + await indexQueue.add({ marketId }) + + return NextResponse.json({ success: true, message: 'Job queued' }) +} +``` + +## Logging & Monitoring + +### Structured Logging + +```typescript +interface LogContext { + userId?: string + requestId?: string + method?: string + path?: string + [key: string]: unknown +} + +class Logger { + log(level: 'info' | 'warn' | 'error', message: string, context?: LogContext) { + const entry = { + timestamp: new Date().toISOString(), + level, + message, + ...context + } + + console.log(JSON.stringify(entry)) + } + + info(message:
