Anthropic's official OS-level sandbox CLI: restricts file and network access for agents, MCP servers and any command without containers, using sandbox-exec on macOS and bubblewrap on Linux. Currently a research preview.

Tells the agent how to export Remotion work: render videos with npx remotion render, stills with npx remotion still, several frames as images in one call with --frames, and videos with a transparent background. Official Remotion skill.

Guides the agent through captions in Remotion videos: stores them as JSON using the Caption type from @remotion/captions, transcribes audio or video to generate them, imports .srt files, and displays and animates them in compositions. Official Remotion skill.

Static security analysis for CI/CD config: finds template injection, credential leaks, excessive permissions and more in GitHub Actions workflows, also covers Dependabot and pre-commit configs, and auto-fixes some findings.

One command extracts or summarizes web pages, PDFs, YouTube videos, podcasts and media files, with JSON output. Summaries can use many model APIs, local models or a logged-in Codex or Claude CLI; plain extraction needs no key. Also has a browser sidebar extension.

Open-source alternative to NotebookLM's podcast feature: turns web pages, PDFs, images, YouTube videos or text into two-host conversational audio, useful for lecture notes or articles. Uses Gemini and OpenAI API keys by default, or local models plus free Edge TTS.

Lets coding agents control real Chrome with short Puppeteer scripts, with named pages that keep state across calls, accessibility-tree snapshots and screenshots for self-testing web changes. Install the dev-browser CLI globally first; macOS and glibc Linux only.

Open-source offline machine translation built on OpenNMT, usable as a CLI, Python library or GUI. Download language packages as needed; when no direct model exists it pivots through an intermediate language. Suits text you would rather not upload to the cloud.

14 skills plus a hook-based reminder layer for use with n8n-mcp: teaches agents to write correct n8n expressions, configure nodes, apply workflow patterns, fix validation errors and deploy self-hosted n8n. Requires n8n-mcp to be set up first.

14 n8n workflow skills: expression syntax, MCP tool usage, node configuration, validation and troubleshooting, Code nodes, AI Agent workflows and self-hosted n8n deployment. Meant to be used with the n8n-mcp server.

21st.dev's official MCP: lets agents search and fetch UI components, themes and template code from the 21st.dev community, and generate components from a description once AI access is enabled. Absorbs the former Magic MCP; requires a free API key from 21st.dev.

ScrapeCreators' official skills: mine public TikTok, Instagram, YouTube, Reddit and X data for viral content, customer voice in comments, competitor accounts and ad libraries, and creator vetting, with sourced reports. Needs a ScrapeCreators key (100 free credits, then pay as you go).

Veteran suite of CSV command-line tools: in2csv converts Excel and JSON to CSV, csvcut, csvgrep and csvsort filter and sort, csvstat computes statistics, and csvsql runs SQL directly against CSV files.

A prose linter that checks docs against style guides: use ready-made packages like Microsoft and Google or write your own YAML rules. It parses Markdown, AsciiDoc and other formats before checking, runs fully offline, and plugs into editors and CI.

Google's official skills for building ADK agents: dev workflow, scaffolding, the ADK Python API, evaluation with LLM judges and adaptive rubrics, deployment to Agent Runtime, Cloud Run or GKE, publishing and observability. Works with agents-cli; local dev needs only an AI Studio key.

Local neural text-to-speech engine that converts text to speech offline, with voices in dozens of languages, handy for listening materials or narrating articles and course slides. Needs Python; download a voice model before first use. The project is currently looking for maintainers.

The .NET team's official skill collection, grouped into plugins: ASP.NET Core, Blazor, MAUI, EF Core data access, MSBuild troubleshooting, performance diagnostics, testing, and framework upgrades and migrations. Maintained by Microsoft; install via the Claude Code or Codex plugin marketplace.

Veteran command-line task manager with projects, tags, priorities, due dates and custom reports, JSON export, and a rich ecosystem of hooks and extensions, well suited for agents that record and track tasks.

Docker's official CLI for building images, running and managing containers, viewing logs and pushing to registries, a foundational tool for agents setting up isolated environments. Needs a local or remote Docker Engine such as Docker Desktop.

Community-maintained MCP for Jira and Confluence: search with JQL/CQL and create or update issues, pages and comments. Supports both Cloud and Server/Data Center deployments; needs an API token or personal access token.

Reference for Nitro v3, the server toolkit behind Nuxt: file routes with H3 v2 handlers, route rules, caching, KV storage, tasks, WebSockets and OpenAPI, plus deploy presets and v2 migration notes. Generated by Anthony Fu from the official docs.

Reference for pnpm 12: CLI, pnpm-workspace.yaml settings, monorepo workspaces, catalogs, overrides, patches, supply-chain settings such as build approval, task orchestration, CI setup and migration from npm, Yarn or older pnpm. Generated by Anthony Fu from the official docs.

Applies Anthony Fu's conventions for JavaScript and TypeScript projects: file organization, explicit imports, Vitest style, @antfu/ni, @antfu/eslint-config with antislop, Knip, tsdown and a single ci script, mirroring the antfu/starter-ts template for new projects.

Reference for Vitest 5: config, CLI, the test, describe and expect APIs, hooks, mocking with vi, snapshots, coverage, fixtures, concurrency, filtering and tags, reporters, benchmarks, test environments, type testing and multi-project setups. Generated by Anthony Fu from the official docs.
