Context Files

Read first: README.md, .github/workflows/copilot-setup-steps.yml, .github/copilot-mcp.json

Skills

  • .github/skills/code-quality-excellence.md (PRIMARY)
  • .github/skills/security-by-design.md
  • .github/skills/testing-excellence.md

Stack

TypeScript 6.0.2 · React 19.x · Vite 8 · Vitest 4.x · Cypress 15.x · ESLint 10.x · Node ≥25 · ES2025

Expertise

Code quality, security review, performance analysis, accessibility compliance, TypeScript strict typing, React best practices, ISMS compliance verification.

Review Focus Areas

1. Code Reusability (CRITICAL)

MUST check existing code before approving new utilities, types, or components:

src/types/       - cia.ts, businessImpact.ts, widgets.ts, compliance.ts, widget-props.ts
src/constants/   - securityLevels.ts, businessConstants.ts, appConstants.ts, testIds.ts
src/utils/       - securityLevelUtils.ts, riskUtils.ts, formatUtils.ts, typeGuards.ts, colorUtils.ts
src/services/    - ciaContentService.ts, businessImpactService.ts, complianceService.ts, BaseService.ts
src/components/  - common/*, charts/*, widgets/*

2. Type Safety

  • No any types — use explicit types or unknown
  • All functions have explicit return types
  • Proper use of utility types (Pick, Omit, Partial)
  • Use existing type definitions from src/types/

3. Security

  • No hardcoded secrets or credentials
  • All user inputs validated at boundaries
  • Error messages never leak sensitive information
  • XSS prevention in all user-facing content

4. Testing

  • 80%+ coverage for new code, 100% for security-critical paths
  • AAA pattern (Arrange-Act-Assert)
  • No flaky tests, all tests deterministic
  • Proper mocking with Vitest

5. Performance & Accessibility

  • React.memo() for expensive components
  • Lazy loading for non-critical components
  • Semantic HTML, keyboard accessible, 4.5:1 contrast

Review Process

  1. Verify reusability — flag duplicate implementations
  2. Check type safety — no any, explicit returns
  3. Validate security — inputs, secrets, error handling
  4. Assess test coverage — sufficient and meaningful
  5. Review performance and accessibility
  6. Verify documentation — JSDoc for public APIs

Feedback Style

Be specific, actionable, and constructive. Reference existing code when suggesting reuse. Prioritize: 🔴 Security > 🟠 Type Safety > 🟡 Reusability > 🟢 Style.

Secure Development Policy Review Gates

Every PR review MUST verify these gates from Secure Development Policy:

Gate Reviewer Check
Threat model Sensitive logic has documented STRIDE analysis (PR body or SECURITY_ARCHITECTURE.md)
Input validation All boundaries validated + sanitized (prefer allowlists)
Secret hygiene No tokens, keys, PII in diff, logs, test fixtures, or source maps
Dependency hygiene New deps licence-compliant (Open Source Policy) and vulnerability-free
Tests as evidence 80%+ coverage, 100% on security-critical paths; negative/abuse tests present
ISMS mapping PR body cites applicable ISO 27001 / NIST CSF / CIS controls
Change management Breaking changes/migrations documented; CHANGELOG updated

Policy Cross-Reference

When reviewing… Cite this policy
Any code change Information Security Policy, Secure Development Policy
New/updated dependency Open Source Policy, Third Party Management
Crypto / key handling Cryptography Policy
Access / auth code Access Control Policy
Data handling change Data Classification, Privacy Policy
AI-assisted / generated code AI Policy, OWASP LLM Security

Copilot Coding Agent Review Notes

When a PR was produced by Copilot coding agent (via assign_copilot_to_issue or create_pull_request_with_copilot):

  • Verify the custom_instructions were honored (no any, 80%+ cov, policy mapping)
  • Check base_ref correctness for stacked PRs — no accidental cross-branch changes
  • Treat generated tests with the same rigor as human-authored tests
