Jamie-BitFlight · 2026-01-19T18:58:22Z

Add README files generated by documentation-generator agent:

.claude/agents/README.md: Documents 4 specialized modernization agents
.claude/checkpoints/README.md: Documents checkpoint system for progress tracking

.claude/hooks/README.md: Documents checkpoint management shell scripts
.github/README.md: Documents GitHub configuration files and workflows
docs/README.md: Updated with modernization plan reference

Multi-agent analysis complete with Chain-of-Verification:

Architecture: 10 source files (655 LOC), 4 classes, no circular dependencies
Validation: TypeScript strict mode, ESLint 20+ plugins, tests (1/2 pass)
Plan: 17 tasks in 5 tiers, jira.js upgrade identified as CRITICAL risk
Documentation: 6 READMEs created with cross-reference validation

Poem

"🐰 I hopped through READMEs with a curious peep,
Checkpoints in my pouch for projects that sleep.
Agents line up neatly, tests spin up and sing,
Containers hum, fixtures click — oh what joy I bring!
A tiny rabbit cheers: modernization spring!"

Add new CI workflow (.github/workflows/ci.yml) that runs: - TypeScript type checking (tsc --noEmit) - ESLint linting - Jest tests with mock environment variables - Build verification (ensures dist/ is up to date) Also update existing workflows to use modern versions: - actions/checkout@v3 → v4 - actions/setup-node@v3 → v4 - Node.js 16 → 20 - Ubuntu-20.04 → ubuntu-22.04 This ensures all code quality checks run in CI, preventing bypassed pre-commit hooks from introducing issues.

Add test:unit script that runs only unit tests (excludes integration tests that require real Jira credentials). Pre-commit now runs unit tests with mock environment variables. - test:unit: Runs unit tests only (safe for local dev) - test: Runs all tests (requires Jira credentials for integration tests) - test-ci: Runs all tests with CI reporters Pre-commit: lint:fix → test:unit → lint-staged → build → generate-docs CI: Runs full test suite with mock credentials

Add comprehensive testing setup with two modes: 1. Docker Jira: Real Jira instance for full integration tests 2. Nock mocking: Fast unit tests with mocked HTTP responses New files: - docker-compose.test.yml: Jira + PostgreSQL for local/CI testing - scripts/test-setup.sh: Helper to manage Docker test environment - __tests__/mocks/jira-api.ts: Nock-based HTTP mocking with record mode - __tests__/fixtures/jira-responses.ts: Sample Jira API response fixtures Test scripts: - test: Full test suite - test:unit: Fast unit tests only (no HTTP calls) - test:integration: Integration tests requiring Jira CI workflow updates: - validate: Fast checks (TypeScript, ESLint, build) - integration-test: Docker Jira with real API calls - unit-test: Mocked Jira API for fast feedback To record new fixtures from real Jira: JIRA_RECORD_MODE=true JIRA_BASE_URL=https://your.atlassian.net \ JIRA_API_TOKEN=token JIRA_USER_EMAIL=email yarn test
