Vercel's official deployment skill: checks the git remote, project link and CLI login, then deploys a preview (default) or production via git push or vercel deploy. When login isn't possible in a sandbox, it can create a claimable preview link.

Processes large tool outputs in a sandbox and returns only the results to context; logs session events in SQLite with FTS5 so work continues after context compaction. Supports Claude Code, Codex and a dozen other clients. ELv2 licensed.

Daemonless, rootless container and pod manager with a Docker-compatible CLI for building, running and pushing OCI images. On macOS and Windows it runs inside a podman machine VM.

Runs the cognee memory engine as an MCP server whose remember, recall and forget tools write documents and conversations into a knowledge graph and vector store for cross-session retrieval. Start it with Docker or uv first; needs an LLM API key by default, or connect to Cognee Cloud.

Fast vulnerability scanner driven by YAML templates: uses a community template library to detect known vulnerabilities over HTTP, DNS, TCP, SSL and more, supports custom templates and plugs into CI/CD. Use only on targets you're authorized to test.

Writes conversations and business data into Graphiti's temporal knowledge graph so agents can retrieve long-term memory by entity, fact and time. Open source from Zep; start FalkorDB or Neo4j and the server with Docker first, and configure an LLM API key.

Grafana's load and performance testing tool: write test scripts in JavaScript covering HTTP, WebSocket, gRPC and browsers, set threshold assertions and run them in CI.

Official web auditing tool from the Google Chrome team: score pages on performance, accessibility, best practices and SEO from the command line and get HTML, JSON or CSV reports, so agents can iterate on a page. Needs Node 22+ and Chrome.

Turns websites and Electron desktop apps into deterministic CLIs, with built-in adapters for Reddit, Hacker News, Bilibili, Zhihu, Xiaohongshu and more, and lets agents operate any page through your signed-in Chrome. Needs its companion browser extension.

Browser Use's video editing skill: put raw footage in a folder and chat with Claude Code or Codex to get a finished cut, with filler words and pauses removed, color grading, burned-in subtitles, animations and per-cut self-checks. Needs ffmpeg, Python (uv) and an ElevenLabs API key.

Detects hardcoded passwords, API keys and tokens in Git repos, files and stdin, and can run as a pre-commit hook or GitHub Action to block leaks. Now feature-frozen with security fixes only, as the author has moved on to Betterleaks.

Open-source infrastructure-as-code tool and community fork of Terraform: describe cloud resources declaratively, run plan to generate an execution plan, then apply changes, creating resources in parallel by dependency graph. Community-governed, MPL-2.0.

Kubernetes package manager that packages, installs, upgrades and rolls back releases with Chart templates, including ready-made charts from Artifact Hub. A CNCF graduated project; needs a kubeconfig to reach your cluster.

Finds leaked credentials in Git, GitHub, S3, filesystems and more, recognizing 800+ secret types and checking with each service whether a key is still live to cut false positives.

Have an agent produce high-fidelity clickable prototypes, editable slides, timeline animations (exportable to MP4/GIF) and infographics in HTML from one sentence. Proposes three design directions first and includes a five-dimension design review. By Huashu, MIT licensed.

Baoyu's (JimLiu) content creation skills: infographics, covers, article illustrations, slide decks, comics and translation, plus Xiaohongshu cards and publishing to WeChat, Weibo and X. Needs Node.js, bun and an image model API key; some skills rely on Chrome automation or unofficial APIs.

Content creation plugin by Baoyu (JimLiu): infographics, article illustrations, covers, slide decks and translation, plus Xiaohongshu image cards and publishing to WeChat Official Accounts, Weibo and X. Needs Node.js; image generation needs an OpenAI, Google or Tongyi Wanxiang API key.

CLI and library for evaluating and red-teaming LLM apps: compare prompts and model outputs in bulk, scan for security vulnerabilities and plug into CI/CD, with evals running locally. Now part of OpenAI and still open source under MIT.

160+ specialized Claude Code subagents, packaged as plugins in 10 categories such as core development, languages, infrastructure, testing and security, and data and AI, so you install only what you need.

Define cloud infrastructure in general-purpose languages like TypeScript, Python and Go, then preview and deploy with pulumi up to AWS, Azure, GCP, Kubernetes and 300+ other providers. Open source and maintained by Pulumi.

Declarative diagram scripting language: describe architecture diagrams, flowcharts and sequence diagrams in concise text with automatic layout, then render with the d2 command to SVG, PNG, PDF or PPTX. Lets agents produce diagrams you can version-control.

Removes image backgrounds with one command: single images, whole folders or watched directories, mask-only output and switchable models like U2Net and SAM. Can also run as an HTTP server or process video frames with FFmpeg. Default models run locally.

Fast speech transcription built on faster-whisper, with word-level timestamps and speaker diarization, suited to meeting notes and subtitles. Diarization needs a Hugging Face token; GPU acceleration needs CUDA.

Veteran open-source video transcoder. HandBrakeCLI uses built-in presets to batch-compress screen recordings, course videos and footage or convert them to MP4, MKV or WebM for phones and the web. Free, runs locally, installable on macOS via Homebrew.
