Convert a Gemini CLI extension into a Claude Code plugin, preserving functionality and backwards compatibility. Use when the user wants to migrate/port a Gemini extension to Claude Code, convert gemini-extension.json to plugin.json, adapt GEMINI.md context or Gemini tools/hooks, or mentions "gemini-extension.json", "GEMINI.md", or "migrate Gemini".

Author, scaffold, or edit a plugin once in Claude Code format, then generate the Codex, Antigravity, and Cursor manifests so one directory loads in all four runtimes. Use when creating/scaffolding a new plugin, editing a plugin or its manifest, wiring a marketplace entry, running the multi-format generator, or when the user mentions "plugin.json", ".claude-plugin", ".codex-plugin", ".cursor-plugin", "multi-format", "marketplace.json", "scaffold a plugin", or "Codex/Cursor/Antigravity plugin".

Thoroughly validate a Claude Code plugin's manifest, directory structure, commands, agents, skills, hooks, and MCP config, then report issues by severity. Use when the user asks to validate, check, audit, or lint a plugin, verify a plugin.json or plugin structure, debug why a plugin won't load, or mentions "plugin validate", "invalid manifest", or "plugin not loading".

Answer questions and write code for TanStack libraries using version-accurate, officially shipped Agent Skills instead of training data. Use when working with any @tanstack/* package or TanStack library: Query (react-query, solid-query, vue-query — useQuery, useMutation, QueryClient, queryOptions, invalidation, optimistic updates), Router (@tanstack/react-router — createFileRoute, loaders, search params, path params, type-safe navigation), Start (full-stack framework — server functions, SSR, streaming), Table (headless tables — useReactTable, columns, sorting, filtering, pagination), Form (useForm, field validation), DB (createCollection, live queries, optimistic mutations, sync adapters), Virtual (useVirtualizer, list/grid virtualization), Store, Pacer (debounce/throttle/queue), AI, Devtools, Config, or CLI. Also use when the user mentions tanstack.com docs or the @tanstack/intent CLI.

Turn complex or visual agent responses into rich, reviewable HTML artifacts the user can annotate and send feedback on, using the lavish-axi CLI. Use when about to give a plan, comparison, diagram, table, code diff, report, or anything easier to grasp visually than as prose.

Set up and use portless for named local dev server URLs (e.g. https://myapp.localhost instead of http://localhost:3000). Use when integrating portless into a project, configuring dev server names, setting up the local proxy, working with .localhost domains, or troubleshooting port/proxy issues.

Turborepo monorepo build system guidance. Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.

Creates isolated Linux MicroVMs using Vercel Sandbox SDK. Use when building code execution environments, running untrusted code, spinning up dev servers, testing in isolation, or when the user mentions "sandbox", "microvm", "isolated execution", or "@vercel/sandbox".

Configure GitHub channel credentials and watched repositories (Personal Access Token, repo list). Use when the user wants to set up GitHub credentials, configure the token, change watched repositories, or check channel status.

Manage GitHub channel access control — sender allowlist and policy. Use when the user asks to allow or remove a GitHub login, change the access policy (open/allowlist), or list the current GitHub channel access state.

Set up the Slack channel — save the bot token and app token, review access policy. Use when the user pastes Slack tokens, asks to configure Slack, asks "how do I set this up" or "who can reach me," or wants to check channel status.

Manage Slack channel access — approve pairings, edit allowlists, set DM/group policy. Use when the user asks to pair, approve someone, check who's allowed, or change policy for the Slack channel.

Author or improve the run-<unit> skill — a per-project skill that tells agents how to build, launch, and drive this project's app. Use when the user asks to set up the project, get it running, write run instructions, or verify build/run steps work from a clean environment.

Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).

Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.

Launch and drive a local reference Claude apps gateway (claude gateway + Dex + Postgres) to probe, capture, or re-verify the login / managed-settings / OTLP-telemetry wire protocol that shunt's gateway superset (login → managed/settings → telemetry, epic

Build, launch, and drive shunt — the Claude Code LLM gateway (a Rust/axum Anthropic-Messages proxy). Use to run, start, smoke-test, or curl-drive the gateway, exercise /v1/models discovery and /v1/messages proxying, or connect Claude Code to a local shunt instance.

Build, run, and drive the asana CLI. Use when asked to run asana, start it, build the binary, smoke-test it, exercise task/workspace/project commands, or verify a change works against a (mocked) Asana API without real credentials.

Manage Asana (아사나) from the terminal with the `asana` CLI — tasks, projects, sections, subtasks, comments, dependencies, followers, tags, attachments, custom fields, CSV/JSON batch import, and workspace/team/user lookups. Use this whenever the user wants to create, list, find, count, update, complete, assign, or delete Asana tasks or projects; add a comment, subtask, due date, or follower; pull their Asana to-do list; or import tasks from a file into Asana — even when they only say "Asana"/"아사나", paste an app.asana.com task or project link, or describe work they want tracked there without naming the CLI. (Does not apply to writing Asana API/SDK code or editing the asana CLI's own source — only to operating Asana through the CLI.)

Bundle TypeScript and JavaScript libraries with blazing-fast speed powered by Rolldown. Use when building libraries, generating type declarations, bundling for multiple formats, or migrating from tsup.

Answer questions about Claude Code (features, hooks, plugins, skills, MCP, Agent SDK, settings, CLI) from the official docs. Uses the ask CLI to resolve a version-pinned local mirror and csp for semantic search, falling back to grep and WebFetch. Use when the user asks how Claude Code works, what a configuration field does, or whether Claude Code supports something.

Guide for writing ast-grep rules to perform structural code search and analysis. Use when users need to search codebases using Abstract Syntax Tree (AST) patterns, find specific code structures, or perform complex code queries that go beyond simple text search. This skill should be used when users ask to search for code patterns, find specific language constructs, or locate code with particular structural characteristics.

Complete guide for Chrome DevTools CLI - browser automation, debugging, performance analysis, network inspection. Use when automating Chrome, taking screenshots, analyzing performance, monitoring network/console, device emulation, or user mentions chrome-devtools, browser automation, puppeteer, debugging, performance testing, screenshot, network monitoring, console monitoring, or 크롬 개발자도구, 브라우저 자동화, 디버깅, 성능 분석.
