- 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
Hook source now lives in hooks/src/*.mts and compiles to hooks/*.mjs via tsc.
The formatOutput() return type is checked against SyncHookJSONOutput from
@anthropic-ai/claude-agent-sdk, preventing unknown fields in hookSpecificOutput
that Claude Code's strict Zod validation would silently reject.
Root cause: skillInjection metadata was a sibling key in hookSpecificOutput,
which Claude Code rejected as "Hook JSON output validation failed: Invalid input".
All skill injections were silently discarded. Now skillInjection metadata is
embedded as an HTML comment inside additionalContext.
- Add hooks/src/*.mts (TypeScript source for all 6 hook modules)
- Add hooks/tsconfig.json (strict, NodeNext, compiles .mts → .mjs)
- Add build:hooks script and pre-commit hook for auto-compilation
- Install @anthropic-ai/claude-agent-sdk as devDependency for types
- Bump plugin version to 0.4.0
PreToolUse now checks VERCEL_PLUGIN_SETUP_MODE and synthesizes a\nbootstrap match when setup mode is active, then boosts bootstrap\npriority so it injects before other matched skills on the first\nrelevant call.\n\nThe routing is dedup-safe: it skips synthetic bootstrap when the skill\nhas already been injected in seen-skills state.\n\nVerified: bun test tests/pretooluse-skill-inject.test.ts -t "setup mode bootstrap routing"\nVerified: node --check hooks/pretooluse-skill-inject.mjs\nSwarm-Agent: codex-profiler-hooks
Session start now scans for bootstrap/setup markers and exports\nVERCEL_PLUGIN_BOOTSTRAP_HINTS, VERCEL_PLUGIN_RESOURCE_HINTS, and\nVERCEL_PLUGIN_SETUP_MODE=1 when signals cross the setup threshold.\n\nThis gives pre-tool hooks deterministic bootstrap context before the\nfirst tool call and helps route setup-focused skills earlier.\n\nVerified: bun test tests/session-start-profiler.test.ts\nVerified: node --check hooks/session-start-profiler.mjs\nSwarm-Agent: codex-profiler-hooks
- Add greenfield project detection to session-start profiler
- Add profiler boost (+5 priority) for likely skills in PreToolUse
- Remove zzz-test-redos-pattern test skill
- Update golden fixtures and snapshots
- Add agent-browser to ecosystem graph
- Add new golden fixture tests
Add a standalone integration test file that validates session-start env export\nand lead/subagent timeline behavior for VERCEL_PLUGIN_SEEN_SKILLS dedup.\n\nVerified: bun test tests/session-timeline-subagent.test.ts (2 pass)\nSwarm-Agent: session-timeline-subagent-integration-test
Add a standalone slack-clone pattern test suite with deterministic skill-order assertions for key route and component paths.\n\nVerified: bun test tests/slack-clone-patterns.test.ts (5 pass)\nSwarm-Agent: slack-clone-pattern-integration-tests
Add a standalone integration test file that validates deterministic skill injection ordering for realistic notion-clone Next.js file paths.
The tests keep local helpers and only assert hookSpecificOutput.skillInjection.injectedSkills to stay focused on path routing behavior.
Verified: bun test tests/notion-clone-patterns.test.ts (5 pass)
Swarm-Agent: notion-clone-pattern-integration-tests
Add a standalone integration test file for subagent fresh-environment dedup behavior around VERCEL_PLUGIN_SEEN_SKILLS and debug strategy events.
Includes three scenarios: no inherited env (memory-only), explicit empty env (env-var), and inherited seen list (dedup to {}).
Verified: bun test tests/subagent-fresh-env.test.ts (3 pass)
Verified: assertions validate hookSpecificOutput.skillInjection.injectedSkills and dedup-strategy debug event
Swarm-Agent: subagent-fresh-env-integration-tests
Update build-manifest.ts to include bodyPath in each skill manifest entry pointing to the SKILL.md file. Update all SKILL.md frontmatter across all skills to ensure consistent formatting. Add vercel-config.mjs improvements for key-aware skill routing.
Add tests/build-skill-map.test.ts for skill map construction. Add golden fixture JSON files (golden-bash-cap-collision, golden-bash-next-dev, golden-edit-middleware, golden-read-env-local, golden-read-vercel-json, golden-vercel-json-crons, golden-vercel-json-rewrites) for deterministic match engine validation. Add tests/fuzz-glob.test.ts and tests/fuzz-yaml.test.ts for property-based testing of the glob-to-regex and YAML parsers.
Update snapshot files for injection output. Update validate.ts and validate.test.ts with command convention checks. Update HOOKS.md documentation. Update pretooluse-skill-inject.mjs, skill-map-frontmatter.mjs, and vercel-config.mjs hook modules. Bump plugin.json version from 0.2.0 to 0.3.0.
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.
The seen-skills dedup was using a temp file written via SessionStart,
but PreToolUse hooks can't update CLAUDE_ENV_FILE. This caused errors
when the temp file became stale or inaccessible across session clears.
Now VERCEL_PLUGIN_SEEN_SKILLS is a comma-delimited string stored
directly in the session environment. SessionStart initializes it as
empty, and the PreToolUse hook reads/updates process.env in-place.
Extract glob-to-regex and seen-skills file utilities into hooks/patterns.mjs
for reuse across the PreToolUse hook and validation script. Add
validateSkillMap to skill-map-frontmatter.mjs. Expand plugin tags for
chat-sdk/bot variants. Comprehensive tests for all new modules.
Replace session-id/tmpdir JSON dedup assumptions with the new VERCEL_PLUGIN_SEEN_SKILLS newline-file flow in hook integration tests.
Covers memory-only behavior without env file, env-file persistence, pre-seeded file behavior, dedup-off and reset controls, strategy debug values, newline-delimited file format assertions, and all_deduped reason handling via shared seen file.
Verified: bun test tests/pretooluse-skill-inject.test.ts (215 pass)

SessionStart now creates a per-session seen-skills text file and exports
VERCEL_PLUGIN_SEEN_SKILLS through CLAUDE_ENV_FILE before PreToolUse runs.
This enables env-file dedup bootstrap without altering existing PreToolUse hook wiring.

Replace centralized skill-map.json with frontmatter-based triggers in
each SKILL.md. Add hooks/skill-map-frontmatter.mjs to parse triggers
at runtime. Update validation, tests, and hook logic accordingly.
In hooks/skill-map.json: add tailwind.config.*, postcss.config.*, tsconfig.json, and tsconfig.*.json to the nextjs pathPatterns. Add bun/yarn install patterns for @ai-sdk/gateway to ai-gateway bashPatterns. Add bun/yarn install patterns for @vercel/functions to runtime-cache bashPatterns. Add bun/yarn install patterns for @vercel/speed-insights to observability bashPatterns.
In hooks/pretooluse-skill-inject.mjs: refactor the hook script for clarity and robustness.
In tests/pretooluse-skill-inject.test.ts: expand test coverage for the new trigger patterns and refactored hook logic.
Create skills/ai-elements/SKILL.md covering the AI Elements component library — 40+ React components for AI chat UIs (Message, Conversation, Tool, Reasoning, CodeBlock, PromptInput) built as a custom shadcn/ui registry. Document installation via `npx ai-elements`, integration with AI SDK v6 useChat/UIMessage parts, server-side patterns (convertToModelMessages async + toUIMessageStreamResponse), and the DefaultChatTransport client pattern.
Create skills/shadcn/SKILL.md covering shadcn/ui — CLI commands (init, add, build, search, migrate), components.json configuration, namespaced custom registries (@v0, @acme), CSS variable theming with oklch, dark mode setup, the cn() utility, TooltipProvider requirement, RTL support, and framework compatibility (Next.js, Vite, Remix, Astro, Laravel).
Create skills/json-render/SKILL.md covering AI chat response rendering — the UIMessage parts format (text, tool-*, reasoning, step-start), manual rendering patterns for custom chat UIs without AI Elements, ToolResultCard patterns for structured tool output display instead of raw JSON, and the 5 most common v6 rendering mistakes (raw JSON from message.content, tool JSON blobs, convertToModelMessages not awaited, toDataStreamResponse vs toUIMessageStreamResponse, v5 useChat API pattern).
In skills/ai-gateway/SKILL.md, add a full "Authentication (OIDC — Default)" section documenting: VERCEL_OIDC_TOKEN provisioned by `vercel env pull`, @vercel/oidc reading the token automatically, ~24h expiry with re-pull for local dev, auto-refresh on Vercel deployments, AI_GATEWAY_API_KEY as manual alternative, and the auth priority order (API key first, then OIDC fallback).
In skills/ai-sdk/SKILL.md, update the setup section to document OIDC as default auth flow (vercel link → enable gateway → vercel env pull → OIDC token auto-provisioned), rewrite the UI Hooks section with both AI Elements (recommended) and manual rendering patterns showing v6 API changes (DefaultChatTransport, sendMessage, status, message.parts), update Key Patterns to include OIDC, AI Elements, and server-side v6 patterns, and expand the migration section with useChat transport, sendMessage, toUIMessageStreamResponse, and message.parts entries.
In vercel.md ecosystem graph: add AI Elements product entry under AI SDK UI Layer with component list and shadcn dependency, add shadcn/ui product entry under Frameworks with CLI commands and registry system, add OIDC Authentication subsection under AI Gateway with token flow, add AI Elements and custom rendering rows to AI Features decision matrix, update "Build an AI Chatbot" workflow with OIDC steps and AI Elements, add 6 new migration table entries (useChat transport, sendMessage, toUIMessageStreamResponse, message.parts, manual API keys → OIDC), and update AI SDK v6 conventions with OIDC-first auth, AI Elements recommendation, and server/client v6 patterns.
In hooks/skill-map.json, add trigger entries for all 3 new skills: ai-elements (components/ai-elements/**, npx ai-elements, shadcn registry URL patterns), shadcn (components.json, components/ui/**, npx shadcn patterns), json-render (components/chat**, components/message*, chat sidebar patterns).
Run the validator (bun run scripts/validate.ts --coverage skip) to confirm all 8 checks pass with 24 skills, 0 orphans, and all skill-map entries valid.
The ecosystem graph now lives at vercel.md (root). Remove the redundant
assets/ directory and update all references in the validator, tests, and
README.
Add bun test suite with validate.test.ts, coverage-baseline.ts for
llms.txt gap analysis, orphan-skill detection in validate.ts, structured
JSON output with --format json, and per-check timing metrics.
