Open-source zero-shot TTS via f5-tts_infer-cli: from a few seconds of reference audio it reads Chinese or English text in the same voice, handy for lessons and videos. Needs Python, PyTorch and FFmpeg, ideally a GPU. Pretrained models are non-commercial; get consent before cloning a voice.

Turns 18 kinds of sources, including doc sites, GitHub repos, PDFs and videos, into skill packages for Claude and other platforms, or exports RAG chunks and vector store data. Optional MCP server, and it can call a local agent like Claude Code to enrich content. Needs Python 3.10+.

Audits a whole React codebase read-only: runs a React Doctor scan as evidence, vets findings across bugs, performance, accessibility, security and maintainability, ranks them by leverage, then writes self-contained plans other agents can execute. Never edits source.

Runs React Doctor via npx to scan React code for security, performance, correctness, accessibility and architecture issues with a 0-100 health score; checks changed code for regressions, and on /doctor fetches the official triage playbook to fix issues.

Writes precise prompts for a specific AI tool: identifies the target tool, extracts your intent, asks at most three questions if details are missing, then outputs a lean, paste-ready prompt. Covers dozens of tools including ChatGPT, Claude Code, Cursor, Midjourney and Sora.

Microsoft Playwright's official browser CLI for coding agents: open pages, click and type, take screenshots and manage sessions, and install the companion skills in one step. Uses fewer tokens than Playwright MCP. Needs Node.js 18+.

Companion skill for the official Playwright CLI: short commands to open pages, click and fill forms, take snapshots and screenshots, and write and debug Playwright tests, using less context than the MCP approach. Maintained by Microsoft; needs Node.js.

Nearly 100 skills spanning the AI research workflow: ideation and literature review, fine-tuning and post-training, distributed training, inference serving, evaluation, interpretability and paper writing, tied together by an autoresearch orchestration skill.

Plugin marketplace for AI research with nearly 100 skills in 23 categories, from ideation, fine-tuning and post-training to distributed training, inference serving, evaluation and paper writing, coordinated end to end by the autoresearch skill.

MiniMax's official skill plugin with dev guides for frontend, full-stack, Android, iOS, Flutter, React Native and GLSL shaders, plus PDF, PowerPoint, Excel and Word document skills and image, video and music generation. Media skills need a MiniMax API key. Still in beta.

MiniMax's official skill collection covering frontend, full-stack, Android, iOS, Flutter, React Native and GLSL shader development, plus PDF, Word, Excel and PowerPoint document generation. Some media skills need a MiniMax API key. Still in beta.

Customizes the Claude Code status line to show model, Git branch, token and context usage, session and weekly limits at the bottom of the terminal. Configured through an interactive TUI with Powerline styling. Claude Code only.

Runs an extremely strict maintainability review of the current branch: hunts for restructurings that make the change dramatically simpler and flags files pushed past 1,000 lines, ad-hoc conditionals, thin wrappers and needless casts. From Cursor's official plugins; invoke manually.

Simon Willison's LLM CLI and Python library: call OpenAI, Claude, Gemini and local models from the terminal, with conversations logged to SQLite automatically, plus embeddings, structured extraction, tool calling and a plugin system.

From Zilliz: indexes your codebase as vectors in Milvus or Zilliz Cloud so coding agents find relevant code by semantic search, cutting context costs in large repos. Needs an embedding model (OpenAI, VoyageAI, Ollama and others) and a vector database.

A du replacement written in Rust that shows disk usage as a directory tree with proportion bars, making large files and folders easy to spot. Filter by depth, count or regex, and output JSON with -j for agents to parse.

Lets agents call thousands of ready-made scrapers and automation Actors from Apify Store to pull data from social media, search engines, maps, e-commerce sites and more. Maintained by Apify; needs an Apify account (OAuth) or API token.

ByteDance's open-source, general software engineering agent: trae-cli edits files and runs commands from natural language, supports multiple model providers and MCP, and records full execution trajectories. Transparent design suits agent research and customization. Needs your own model API key.

Bundles 60+ full-stack specialist skills into one plugin: experts for 12 languages including Python, TypeScript, Go, Rust and Java, and frameworks like React, Django and Spring Boot, activated automatically by request. Also includes Jira and Confluence workflow commands (needs Atlassian MCP).

Connects to the Arize Phoenix observability platform so agents can query LLM traces and sessions, manage prompts, browse datasets and read experiment evaluation results. Maintained by Arize; needs a self-hosted or cloud Phoenix instance.

Lets Claude Code, Codex and other agents call Gemini, GPT, Ollama and other models to collaborate on code review, debugging, planning and multi-model consensus, and can bridge to other CLI agents. Configure at least one provider (API key or local Ollama). Formerly Zen MCP.

Reads local session files to report token usage and cost by project, model, task and branch for Claude Code, Codex, Cursor and dozens of other coding agents, no sign-up needed. Also offers config optimization tips, quota checks and spend-cap hooks. Needs Node.js 22.13+.

GitHub's official terminal coding agent, sharing its harness with the Copilot coding agent and shipping with the GitHub MCP built in. Work with repos, issues and PRs in natural language, approving each action before it runs. Requires a Copilot subscription.

Google's official dependency vulnerability scanner: parses project lockfiles and container images, checks them against the OSV.dev database to find affected dependencies, and can suggest upgrade fixes (experimental).
