Deployment tool and support utility for AI context. Copies agents, skills, commands, rules, and behaviors into the paths each AI platform reads (Claude Code, Codex, Copilot, Cursor, Warp, OpenClaw, and 6 more) so one source of truth works across 10 platfo

# Test Watcher

Reactive test execution behavior. Watches for source and test file changes, runs the relevant tests, and reports results.

## When Triggered via NLP

Start watching for file changes and run related tests automatically. Report pass/fail status and coverage deltas.

## When Triggered via Hooks

### on_file_write (source files)

When a source file changes, identify and run tests that import or reference the changed module. Use file naming conventions (`foo.ts` -> `foo.test.ts`) and import graph analysis when available.

### on_file_write (test files)

When a test file changes, run that specific test file immediately.

### on_schedule (every 2 hours)

Run the full test suite and generate a coverage report to `.aiwg/reports/testing/`.
