TypeScript version migration guide (5.x to 6 to 7, tsgo native port). Use for TS 6 tsconfig breaking changes, TS 7 Go rewrite rollout, or TS5xxx deprecation codes.

Discover and reduce task unknowns — blindspots, missing context, unknown unknowns — before committing to a plan, implementation, review, or merge.

by Claude Skills Maintainers

TypeScript-first schema validation and type inference. Use for validating API requests/responses, form data, env vars, configs, defining type-safe schemas with runtime validation, transforming data, generating JSON Schema for OpenAPI/AI, or encountering missing validation errors, type inference issues, validation error handling problems. Zero dependencies, compact core (~5kb gzipped; zod/mini ~1.9kb).

Claude Code hooks for enforcing best practices and workflow automation

by Anthropic

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Looks up current library documentation, API references, and code examples via Context7 (ctx7 CLI or the Context7 MCP server) with a two-step resolve-then-query workflow: a lookup skill (default lookup plus an upstream drift-check action) and a setup skill for CLI install, auth, and MCP configuration.

by Melodic Software

Live E2E browser automation via Microsoft's @playwright/cli: named sessions, accessibility-ref snapshots, click/fill by ref, screenshots, console and network capture, mocking, tracing, video, and auth state, with artifacts written to disk so only paths enter context, plus a vendored upstream baseline and maintainer drift-check update flow.

Shape Up SDLC harness for Claude Code: shaping, intake, orient, scope-mapping, building (T0-verified, sandboxed, scope-contracted), evaluation and QA skills orchestrated by a tech-lead.

Automated governance, versioning, and discovery tools for Claude Code.

A committed, Obsidian-style codebase map for a project: brain/INDEX.md indexes areas, key files, and notable classes/entrypoints so a fresh Claude session starts oriented. A SessionStart hook injects the compact map (with a staleness hint when it lags HEAD); /brain reads it and /brain index builds/refreshes it. Builds the map only — it never annotates code, and nothing outside brain/ is ever modified.

See real components before deciding: /design-lab:preview renders 2-3 candidate variants with the project's OWN components on its own dev server (Vite React/Vue/Nuxt or Laravel Blade/Livewire, scratch surface removed at cleanup, strict consent gate, shell-mockup fallback for greenfield); and two MCP servers read component registries from the source, never from memory — a dependency-free local one for Aceternity, shadcn and Magic UI (24h-cached, every answer carrying its source URL, fetch date and stale flag, 3D/particle runtimes flagged) plus ReUI's own hosted server, delivered by install and authenticated by the user's own browser sign-in.

Independent stronger-model second opinion at key moments — stuck debugging or an imminent irreversible action. /fresh-take:consult composes a facts-only brief (no leaning) and dispatches a blind stronger-model consultant with read-only repo access; it returns a Take, Risks, and one Alternative. A UserPromptSubmit reminder hook nudges the command on key-moment phrases. Advice only — it never blocks, gates, or edits anything.

Cross-session self-improvement loop: mines session and subagent transcripts for recurring friction and proposes CLAUDE.md rules, skill/plugin ideas, and defects against the plugin artifact that was running — applied only on approval.

by Ivan-WG

Scan the current project's manifests and suggest every cc-plugins-marketplace plugin in three tiers — stack-matched, the curated any-project core, and the universal remainder — then install the picked ones after confirmation; --yes auto-installs the first two tiers, --full installs everything relevant to the detected stack after one plan confirm (--stack a,b,c fills in a stack the manifests do not show yet), --all offers every row explicitly, --persist/--global choose scope. Includes /plugin-scout:suggest.

by Ivan-WG

File-aware skill auto-routing: a PostToolUse hook injects one additionalContext directive to load the relevant best-practice skill(s) when you edit a matching file (PHP/Laravel/Blade, React/Vue/Inertia/Livewire via .tsx/.jsx/.vue, plain .ts/.js/.py/.go/.rb/.rs, SQL and migrations (one engine-agnostic rubric, plus a MariaDB row where that engine is detected), components, tests, Dockerfiles, OpenAPI), a SessionStart hook primes a repo-tailored skill index, and low-confidence content signals flush as one digest on your next prompt (SessionEnd keeps the ledger). Every relevant skill co-fires per edit; fail-open, once per skill per session.

Know what is installed, keep it healthy, find what to add. /stack-scan:report inventories manifests, lockfiles (composer, npm/yarn/pnpm/bun), runtimes and docker images into a required-vs-installed table with drift, missing locks and EOL majors flagged. /stack-scan:audit runs the composer/npm vulnerability, outdated and licence checks (package-hygiene) — report-only. /stack-scan:suggest reads the same manifests and suggests every marketplace plugin in three tiers with cited evidence (--yes auto-installs tiers 1-2, --full the whole stack-relevant set after one confirm, --persist/--global set scope); --skills searches skills.sh for third-party skills instead — provenance, preview, explicit picks only. Add-at-all is approaches' build-vs-buy.

by Ivan-WG

Five expert reviewers that RUN the project's own static analysis instead of reciting a best-practice checklist: php-expert (phpstan, psalm, phpcs, rector), ts-expert (tsc, eslint, biome, oxlint), react-expert (the hook rules), vue-expert (vue-tsc, eslint-plugin-vue) and ui-expert (stylelint, pa11y, lighthouse-ci, axe). A detect-analyzers.sh mechanism reports which tool is configured, which one CI actually enforces, what the baseline already forgives and which rules are switched off — so the headline finding is the analyzer's blind spot, which no remembered rubric can produce. Read-only; fixes route to the existing workers.

Deep TypeScript production guidance for testing, tooling, modules, packaging, and type-system work.

Scout skills.sh — Vercel's open agent-skills directory — for third-party skills matching the project's stack: scans manifests, queries the skills.sh search API, reports each hit with provenance (source repo, install count, skills.sh URL), previews the picked skills' SKILL.md before anything lands, then installs only explicit picks via npx skills add — project-level, never global, never auto-installed. Includes /vercel-skills-scout:suggest.

Slash command to sync installed plugins with the claude-config marketplace.
