Converts AsciiDoc, a Markdown-like plain-text markup, into HTML5, DocBook and man pages, and with official extensions into PDF and EPUB, suited to technical books, textbooks and large manuals. Ruby-based; install with Homebrew on macOS.

Gives agents Exa web search and page content fetching, with an optional multi-step research agent and advanced filtered search. Maintained by Exa; the hosted service works anonymously with limits, and signing in or adding an API key raises them.

WordPress's official CLI: install and update plugins and themes, manage posts and users, import and export content, run database search-replace and configure multisite from the terminal, without opening wp-admin. Requires PHP 7.2.24 or later.

Mermaid's official CLI, mmdc: renders flowcharts, sequence diagrams and other Mermaid definitions to SVG, PNG or PDF, and can batch-convert mermaid code blocks in Markdown into images. Requires Node.js.

CLI and TypeScript runtime for discovering and calling MCP servers from the terminal and scripts: list tool signatures and call tools directly, or generate a standalone CLI or typed client from a server. Auto-imports existing MCP configs from Claude Code, Codex and others.

Empirical social science skills from Stanford REAP and CoPaper.AI, bundling 77 in-house and third-party collections: topic selection, literature reviews, DID/RD/IV identification, regression tables in Python, Stata or R, robustness audits and paper writing. Stata flows need Stata installed.

Runs Google Lighthouse across an entire site (sampling similar pages smartly) and summarizes SEO, performance and accessibility scores page by page in a local web UI; unlighthouse-ci writes reports directly for agents to read. Great for site-wide SEO checkups. Needs Node.js 22.18+.

Read-only mirror of the community plugin marketplace maintained by Anthropic, with 2,000+ community plugins that passed submission review and automated security scans, for Claude Code and Claude Cowork.

Cloudflare's official Workers CLI: develop and debug Workers locally, deploy them, manage D1, R2, KV and other resources, and tail live logs. Cloudflare recommends installing it per project; requires a Cloudflare account.

Notion's official self-hosted MCP: uses an integration token to search, read and write pages and data sources, and can read and edit pages as Markdown. Notion now recommends its hosted Remote Notion MCP, and this repo is no longer actively maintained.

17 social media skills from MarTech AI newsletter author Charlie Hills: build a voice profile from an interview and 3-5 past posts, then write LinkedIn posts, Reels scripts, hooks and content matrices, plus Gemini prompts for thumbnails and carousels. Some skills take optional Apify or Gemini keys.

Moves files to the trash instead of deleting them, with commands to list, restore and empty trashed files, so anything an agent deletes by mistake can be recovered. Follows the FreeDesktop.org trash spec and shares the trash with GNOME and KDE.

English prose linter that turns usage guides such as Garner's and advice from great writers into rules, flagging clichés, redundancy, bad comparisons and usage errors line by line, with JSON output for agents. Runs locally with Python; English only.

Stores agent memory as local Markdown notes that both people and AI can read, write, search and link, and you can open them directly in Obsidian. Local-first, open source and free, with a paid cloud sync option.

Uses Obsidian's community Local REST API plugin so agents can list, read, search, append to and delete notes, and insert content at a heading, block reference or frontmatter field. Install that plugin and configure its API key first.

Firebase's official CLI: deploy Hosting, Cloud Functions and security rules, run local emulators, read and write databases and import or export users. The same repo also provides the official Firebase MCP server. Requires a Firebase sign-in.

Lets agents manage Firebase projects: read and write Firestore and Realtime Database, manage Auth users, validate security rules, and check Crashlytics crashes and function logs. Maintained by Firebase; sign in to the Firebase CLI first.

Teaches agents to code against the latest Gemini API and Python/TypeScript SDKs: multi-turn chat, function calling, structured output, and image and speech generation, while avoiding deprecated older models. Maintained by Google's Gemini team.

Gemini API development skills: gemini-api-dev (core API and SDKs), gemini-live-api-dev (real-time bidirectional audio/video streaming) and gemini-omni-flash-api (Omni video generation and editing), filling in APIs released after model training cutoffs. Maintained by Google's Gemini team.

Mixedbread's official semantic grep: search code, text, PDFs and images in natural language, and hook it into Claude Code, Codex and other coding agents in one step to cut token use. Requires a Mixedbread sign-in, and files are synced to its cloud index.

Writes or rewrites English docs in the spirit of ASD-STE100 Simplified Technical English: short sentences, active voice, condition before command, one word one meaning, terms defined at first use. Plain mode by default, Strict mode for STE compliance, plus a rule-by-rule check mode.

Keeps agents from reporting done too early on substantial work: writes acceptance gates with runnable checks before starting, runs only user-approved commands, splits large jobs into a depth tree of verified leaves, and re-checks evidence before reporting. Optional Claude Code Stop hook.

Visually compares two PDFs page by page: reports differences via exit code, writes a PDF with differences highlighted, or opens a GUI for side-by-side review. Useful for checking contract or generated-document revisions. No longer actively developed.

Spec-driven development MCP: the agent writes requirements, design and task docs in three steps, then implements task by task. A web dashboard or VS Code extension lets PMs review, comment, approve and track progress. Needs Node.js; launch the dashboard separately via npx.
