Eval analysis of 9 real sessions showed 10 skills never triggering despite being
requested. Root causes: pathPatterns too narrow (agents write to lib/email-template.tsx
not emails/), promptSignals containing regex instead of plain text (vercel-sandbox),
and missing promptSignals entirely (v0-dev, vercel-firewall).
Skills updated: email, vercel-queues, edge-runtime, vercel-firewall, chat-sdk,
v0-dev, vercel-sandbox. New skill: next-forge (bootstrap detection).
- Replace tsc+cp+rm pipeline with tsup (7ms builds, no intermediate dir)
- tsup compiles hooks/src/*.mts directly to hooks/*.mjs
- tsconfig.json retained for type-checking only (noEmit)
- Remove all .sh references from tests, docs, and hooks.json
- Fix glob pattern test to handle tsup's output format
Create hooks/vercel-config.mjs that reads vercel.json and maps top-level keys (rewrites, redirects, headers, crons, functions) to skill slugs, so skills are injected when the project uses those Vercel features.
Create hooks/logger.mjs with structured logging at four levels (off, summary, debug, trace) controlled by VERCEL_PLUGIN_LOG_LEVEL env var. Support legacy VERCEL_PLUGIN_DEBUG=1 mapping to debug level.
Create src/cli/explain.ts that takes a tool name and input JSON, runs the match engine, and prints which skills would fire and why. Create src/cli/index.ts as the CLI entry point. Create src/commands/doctor.ts for diagnosing plugin setup issues.
Create src/shared/logger.ts and src/shared/match-engine.ts as TypeScript versions of the shared utilities.
Create scripts/build-manifest.ts that reads all SKILL.md files, parses frontmatter, and generates generated/skill-manifest.json.
Add CLAUDE.md documenting the architecture, dedup contract, YAML parser quirks, test conventions, and log levels.
Add tests: tests/cli-explain.test.ts, tests/logger.test.ts, tests/vercel-config.test.ts, tests/snapshot-runner.test.ts with snapshot files in tests/snapshots/. Add test fixtures in tests/fixtures/. Update existing tests to copy new hook modules (logger.mjs, vercel-config.mjs) into temp dirs.
Update package.json with new bin entry and dependencies.
