A hand-picked collection of the finest of resources for the most awesome of agents, Claude Code, the undisputed champion of coding companions, from the unstoppable team at Anthropic PBC. A delectable showcase of top tier skills, ambidextrous agents, scintillating status lines, top notch developer tooling, and also we have plugins. Suitable for beginners and veterans, with an emphasis on code quality, security, and originality.

The current iteration of the list, such as you see it today, was launched with the express intent to highlight resources that were not on the last iteration, and in particular to make selections from the list of recommendations. However, this is only temporary - resources will continue to be added over the coming weeks, and "legacy" resources will be migrated to the new format. So, if you had been featured on the list before, and you don't see your project now, that's the reason why - "legacy" resources that are still maintained and awesome will be added back in soon - and, in the meantime, they are also preserved (but will not be updated) in the README_ALTERNATIVES directory.

Documentation, Knowledge & Learning

• Agentic Workflow Patterns by ThibautMelen - A comprehensive and well-documented collection of agentic patterns from Anthropic docs, with colorful Mermaid diagrams and code examples for each pattern. Covers Subagent Orchestration, Progressive Skills, Parallel Tool Calling, Master-Clone Architecture, Wizard Workflows, and more. Also compatible with other providers.
          

• Bloom by Li-Evan - A self-contained Claude Code skill that turns Benjamin Bloom's "2-sigma" tutoring research into a personal AI tutor: it generates a structured syllabus, teaches one lesson at a time, and adapts each next lesson to the learner's annotations and feedback. The skill is dependency-free and makes no network calls beyond the configured LLM endpoint (an optional web app is also included).
          

• cc-thinking-skills by tjboudreaux - A collection of installable thinking-framework skills with a meta-router, notable for publishing a replication-gated evaluation instead of unsupported quality claims.
          

• Claude Code Handbook by nikiforovall - Collection of best practices, tips, and techniques for Claude Code development workflows, enhanced with distributable plugins

• Claude Code Repos Index by Daniel Rosehill - This is either the work of a prolific genius, or a very clever bot (or both), although it hardly matters because the quality is so good - an index of 75+ Claude Code repositories published by the author - and I'm not talking about slop. CMS, system design, deep research, IoT, agentic workflows, server management, personal health... If you spot the lie, let me know, otherwise please check these out.
          

• Claude Code System Prompts by Piebald AI - All parts of Claude Code's system prompt, including builtin tool descriptions, sub agent prompts (Plan/Explore/Task), utility prompts (CLAUDE.md, compact, Bash cmd, security review, agent creation, etc.). Updated for each Claude Code version.
          

• claude-code-android by ferrumclaudepilgrim - A thorough, device-tested guide and toolkit for running Claude Code natively on Android via three paths (Termux, proot-Ubuntu, and the Android Virtualization Framework), with a verification harness and per-device results. Unusually security-aware for a setup guide — it ships a threat model, an SSRF-guard WebFetch hook, a biometric approval gate, and a permission matrix.
          

• claude-code-docs by Constantin Shafranski - A mirror of the Anthropic© PBC documentation site for Claude/Code, but with bonus features like full-text search and query-time updates - up-to-the-minute, fully-indexed information so that Claude Code can read about itself.
          

• ClaudoPro Directory by JSONbored - Well-crafted, wide selection of Claude Code hooks, slash commands, subagent files, and more, covering a range of specialized tasks and workflows. Better resources than your average "Claude-template-for-everything" site.
          

• Codebase to Course by Zara Zhang - A Claude Code skill that turns any codebase into a beautiful, interactive single-page HTML course for non-technical vibe coders.
          

• cxpak by Barnett Studios - A code-intelligence Claude Code plugin and MCP server (Rust, single binary, 43 languages) that builds a typed dependency graph and packs token-budgeted, annotated context bundles for any task. Exceptionally engineered and security-forward — 2,400+ tests, recorded ADRs, a sandboxed WASM plugin SDK, and cosign-signed, SBOM-attested release images.
          

• Dive into Claude Code by VILA-Lab - A research-lab systematic analysis of the Claude Code codebase whose headline finding — overwhelmingly infrastructure rather than model — reframes Claude Code as a harness.
          

• Encyclopedia of Agentic Coding Patterns by Wolf McNally - A freely available reference covering 190+ patterns for AI-assisted software development (and actually a whole bunch of related technical topics) from foundational concepts through agentic construction patterns, governance, testing, and socio-technical systems. Each entry follows a consistent pattern-language format with Context, Problem, Forces, Solution, Consequences, and Related Patterns. Opinionated and erudiate, which is actually good for an "encyclopedia" in some ways.

• learn-faster-kit by Hugo Lau - A creative educational framework for Claude Code, inspired by the "FASTER" approach to self-teaching. Ships with a variety of agents, slash commands, and tools that enable Claude Code to help you progress at your own pace, employing well-established pedagogical techniques like active learning and spaced repetition.
          

• MDXG Redline by oubakiou - A Claude Code skill plus single-file HTML tool that closes the human-review loop on AI-written docs: a person leaves inline comments in the browser, which export as structured JSON keyed by heading path and line, and the skill polls for that file and applies each comment to the exact lines. Strongly privacy-respecting — the local/CLI build enforces a strict CSP (connect-src 'none'), so document text and comments never leave the machine.
          

• NotebookLM MCP by Romain Peyrichou - A mature MCP server (plus a 33-endpoint REST API) that drives Google NotebookLM for citation-backed Q&A and full Studio generation (audio, video, infographics, reports), with multi-account TOTP re-auth. Notably well-maintained and security-attentive — batch-tested on overnight 1,000-question runs, with a documented changelog that includes patching a transitive XSS advisory.
          

• RAG Learning Academy by Taka Goto - A multi-agent Claude Code learning environment for mastering Retrieval-Augmented Generation, with 20 specialist agents, 22 slash commands, and a 9-module hands-on curriculum that runs zero-config inside Claude Code. Quality is evident — 616 tests, CI, and weekly/monthly content-freshness automation that opens issues for stale material.
          

• showreel by HeyRenan - A Claude Code plugin that turns CSS selectors + text into finished visual documentation — annotated screenshots, flow GIFs/MP4s, terminal recordings, and before/after composites — placing every annotation deterministically and pixel-verifying each artifact (PASS/FAIL) before it is saved. Self-contained (bundles its own headless Chromium, no browser MCP, no telemetry); every image in its README is generated by the tool itself.
          

Obsidian

• agentcairn by ccf - Long-term, cross-project memory for AI coding agents. Your own Obsidian vault as the source of truth. Daemonless and without opaque databases, your memory belongs to you.
          

• Bedrock by Iury Krieger - A Claude Code plugin that turns an Obsidian vault into a structured second brain via 8 skills, building an entity-typed (actors/people/teams/topics…) Zettelkasten graph with bidirectional wikilinks and ingesting Confluence, Google Docs, GitHub, and docling-supported files. Operates only on local markdown, with conscientious, opt-out error reporting that explicitly never transmits vault content or paths.
          

• claude-obsidian by Agrici Daniel - Self-organizing AI second brain for Obsidian + Claude Code. Claude reads any source, links it, and files it into one connected knowledge graph of plain Markdown. Based on Karpathy's LLM Wiki pattern.
          

• Librarian by ngmeyer - A standalone MCP server that gives Claude a markdown second-brain over any Obsidian vault or folder of .md files, with trigram search, auto-wikilinks on write, and real graph analytics (Louvain communities, PageRank, shortest-path, D3 visualization). Runs entirely locally with no network calls or telemetry, productionizing the "LLM wiki" pattern.
          

Open Source Software

• Netresearch Agentic Skills by Netresearch - Skills for assessing and enhancing software projects to meet enterprise-grade standards for security, quality, and automation. Strong collection covering a range of development frameworks, enterprise-readiness, security, GitHub release management, branding, code review - really useful and well curated.
          

• OSS Autopilot by John Costa - End-to-end open source contribution manager. Discovers contributable issues across GitHub, tracks PRs across multiple repos, diagnoses CI failures, and drafts maintainer responses. Great collection of skills and agents for GitHub contributors, plus a sleek dashboard, standalone CLI and MCP server.
          

Research & Scientific Inquiry

• AI Research Skills by Wenyu Chiou - A catalog of 15 Claude Code skills mapped to 8 research-workflow stages (literature → gap analysis → design → drafting → reviewer response), where each stage emits an explicit YAML/Markdown deliverable the next stage consumes. Thoughtfully designed around anti-hallucination — schemas force "gap" status on unsupported claims, and downstream skills refuse malformed, overconfident handoffs.
          

• Claude Scientific Skills by K-Dense - "A set of ready-to-use Agent Skills for research, science, engineering, analysis, finance and writing." That's their description - modest, simple. That's how you can tell this is really one of the best skills repos on GitHub. If you've ever thought about getting a PhD... just read all of these documents instead. Also I think it IS an AI agent or something? Awesome.
          

• My Claude Code Setup by Pedro H. C. Sant'Anna - A ready-to-fork Claude Code template for academics using LaTeX/Beamer + R. Multi-agent review, quality gates, adversarial QA, and replication protocols. Great use of orchestration patterns and great documentation.
          

Providers, Runtime & Integration Infrastructure

• chrome-cdp-ex by Endeavor Yen - A zero-dependency Claude Code skill (68 commands) that connects to your real Chrome — logged-in tabs, cookies, live page state — to give the agent a perception layer: layout, visible styles, per-action "what changed" evidence, CSS-cascade-to-source tracing, and session replay/Playwright export. Notably rigorous about its own claims, with a dogfood benchmark gate that blocks performance/adoption assertions unless it passes.
          

• Claude Codex Settings by fatih akyon - A well-organized, well-written set of plugins covering core developer activities, such as working with common cloud platforms like GitHub, Azure, MongoDB, and popular services such as Tavily, Playwright, and more. Clear, not overly-opinionated, and compatible with a few other providers.
          

• claude-code-wsl2-setup by congmnguyen - A focused collection of documented scripts that fix the most painful Claude Code papercuts on WSL2 + Windows Terminal — clipboard screenshot paste via a Go daemon, Windows notifications on Stop/PermissionRequest hooks, LSP wiring, a usage-aware status line, and voice-mode audio routing. Each fix is written up with root cause and exact config (including non-obvious traps like SessionEnd firing per subagent), and the work was upstreamed into Awesome-WSL.
          

• Codex Skill by klaudworks - Enables users to prompt codex from claude code. Unlike the raw codex mcp server, this skill infers parameters such as model, reasoning effort, sandboxing from your prompt or asks you to specify them. It also simplifies continuing prior codex sessions so that codex can continue with the prior context.
          

• Flue by S.F. Kislev - A tiny bridge that lets Claude Code drive desktop software — Photoshop, Premiere, Blender, Unity, InDesign, Office, 13 apps total — by writing one-time scripts against each app's own automation runtime (COM / AppleScript / CEP), instead of MCP servers or fragile screenshot-based computer use. A genuinely novel approach that unlocks the apps' full scripting surfaces (InDesign alone exposes ~28k objects) with low maintenance.
          

• Fusion Harness by disler - Fuses 2–5 frontier models instead of racing them — one architect, one primary builder, and up to three secondary builders — giving N-way opinions, debate, fusion, coordinated implementation, direct one-agent routing, and gate-first validation. Ships as a composable Pi extension with pre-built model stacks and install/prime commands, and a video walkthrough of the whole approach.
          

• llm-router by Yali Pollak - A local-first router that sits under Claude Code (and Codex/Gemini CLI) and sends each prompt to the cheapest capable model, with three-layer token compression and automatic provider fallback — protecting your premium quota and cutting cost with zero config on a Claude subscription. Credibly engineered: 1,900+ tests, an independent RouterArena benchmark placement, and an honest local-only design with no hosted proxy.
          

• OpenWeb by openweb-org - An agent-native skill that accesses 90+ websites by calling their underlying APIs directly (typed JSON in, JSON out) instead of screenshotting and parsing the DOM, with auth auto-resolved locally from your existing browser session. Security is first-class — every operation is tagged read/write/delete/transact behind permission tiers, SSRF protection runs on each request, and there is no vendor backend or proxy in the request path.
          

• SPARDA by Zakaria Gharzouli (Residual Labs) - Converts a running Express or FastAPI app into an MCP server by AST-parsing its routes and injecting a marked, byte-for-byte-removable /mcp router, so the agent can operate your live application (real auth, real data) rather than just read files. Exceptionally safety-minded: writes are disabled by default behind two-phase confirmation, docstrings are sanitized against prompt injection, a circuit-breaker quarantines failing routes, nothing leaves the machine, and persistence stores structure never payloads.
          

Remote Control, Notifications & Voice I/O

• ai-agent-notifier by Amin Dhouib (Devino Solutions) - A zero-dependency, cross-platform notifier that fires a desktop toast and a free phone push (via ntfy) the moment Claude Code (or Codex/Cursor/Gemini) finishes a task or needs input, wired up by a one-command setup. The standout among notifiers is its testing rigor — CI drives the real agent CLIs end to end and asserts real ntfy round-trips and real OS toast delivery, no mocks.
          

• Claude Threads by Anne Schuth - Streams a locally-running Claude Code session live into a Slack or Mattermost thread so a whole team can watch, type, and approve actions together — "screen-sharing for AI pair programming, but everyone can type." Mature and well-maintained (npm-published with CI and coverage), with reaction-based tool approvals, git-worktree isolation, multi-account rotation, and per-thread sessions that survive restarts.
          

• Claudio by Christopher Toth - A no-frills little library that adds delightful OS-native sounds to Claude Code via simple hooks. It really sparks joy.
          

• dictate by Vimal Kumar - Local, offline voice-to-text for Claude Code on Linux built on faster-whisper, with a warm daemon for instant transcription, system-wide push-to-talk, a voice-enabled editor, and per-project vocabulary hints that fix technical terms ("Claude" not "cloud"). Fully private — no cloud, no API keys, with thoughtful touches like mic-health monitoring and the ability to offload transcription to a LAN GPU; hardware-tested down to a Jetson Orin.
          

• Lockpaw by Erik Nielsen - A native-Swift macOS menu-bar app (10 MB, no Electron) that covers and input-locks your screen with one hotkey while your agents keep running, then makes the locked screen glow when Claude Code pauses for permission or finishes. Polished and well-engineered — CI with 50 tests, signed/notarized builds, an honest "visual privacy tool, not a security boundary" disclosure, no analytics, and an idempotent hook installer that backs up and never clobbers foreign hooks.
          

• Telegram-Claude (tg-claude) by Imolatte - A feature-rich Telegram bot that turns your machine into a remote Claude Code terminal driven from your phone: streaming tool progress, voice input, a git panel, Mac remote control, and 30+ commands. Its standout is the approval flow — dangerous-op Approve/Deny taps are injected straight into the real terminal prompt via tmux send-keys, so you authorize from your phone without killing the session or losing context.
          

• WhatsApp Channel Plugin by Richie Liu - Connects WhatsApp as a native Claude Code channel via Baileys linked-device (no bot token or API keys), with bidirectional messaging, full media, voice transcription, remote tool approval, access control, and per-group personalities. Runs entirely locally and was the first community plugin officially reviewed and published on Anthropic's plugin marketplace.
          

Alternative Clients

• Cate by 0-AI UG - A cross-platform desktop IDE built on an infinite zoomable canvas, where editors, terminals, browsers, and docs float in freeform space instead of tabs — and ships skills that let Claude Code spawn agent terminals on the canvas, coordinate through canvas notes, and drive browser panels. A genuinely novel UX, well-engineered (CI, e2e tests, context-isolated IPC, scoped filesystem access) and widely adopted.
          

• Claude Overlay by shengyanlin - A frameless, always-on-top floating chat window for Claude Code on Windows. It captures every monitor and lets Claude read the screen to answer questions in context, and drives the user's existing claude CLI login through the Agent SDK, with image paste, model switching, live streaming, and a context-usage statusline.
          

• CloudCLI (Claude Code UI) by siteboon - A web and mobile PWA for driving Claude Code (and Cursor/Codex/Gemini) from any device — file explorer, git, integrated shell, and full session management that reads and writes your real ~/.claude config rather than duplicating it. By far the most-adopted Claude Code UI, with a self-hostable open-source core, an optional Docker microVM sandbox mode, a plugin ecosystem, and tools disabled by default for safety.
          

• FlyCrys by Sergii Kamenskyi - A native Linux GUI for Claude Code agents built in Rust + GTK4 — single binary, no Electron, starts in under a second — with a file tree, syntax-highlighted viewer, markdown preview, embedded VTE4 terminal, streaming agent chat, workspace tabs, and tool-restricted agent profiles. Fills a real gap as essentially the only native (non-webview) Linux desktop client, using your own Claude Code CLI with no proxy.
          

• Happy Coder by GrocerPublishAgent - Spawn and control multiple Claude Codes in parallel from your phone or desktop. Happy Coder runs Claude Code on your hardware, sends push notifications when Claude needs more input or permission, and costs nothing. End-to-end encrypted, with realtime voice.
          

• Nimbalyst by Greg Hinkle - A visual workspace for building with Claude Code (and Codex) where you and the agent co-edit visually — markdown, mockups, mermaid, Excalidraw, CSV, and data models — approving the agent's changes as red/green WYSIWYG diffs, with session/task kanban, worktrees, an extension SDK, and a native iOS companion app. A distinctive higher-bandwidth take on agent collaboration, open source with transparent, opt-out telemetry.
          

• Sidekick for Max by César Andrés López - A VS Code extension and standalone terminal dashboard that adds visibility and AI conveniences on top of your Claude Max subscription — inline completions, code transforms, AI commit messages, plus deep session observability (token-burn, a 13-week quota heatmap, multi-account management, cross-session search, and asset extraction). Mature and well-maintained (CI, published to the marketplace and npm, extensive docs).
          

• Vibeyard by Eliran Tutia - A cross-platform desktop IDE that wraps Claude Code sessions with a swarm mode (parallel agents in a grid), a real-time session inspector (cost, tokens, tool-usage, context), multiple isolated Claude profiles, a kanban board, and encrypted P2P session sharing over WebRTC. Signed/notarized, broadly adopted, and built squarely for the multi-agent, multi-session workflow.
          

Status Lines

• CCometixLine by Haleclipse - A high-performance Claude Code statusline tool written in Rust with Git integration, usage tracking, interactive TUI configuration, and Claude Code enhancement utilities.
          

• ccstatusline by sirmalloc - A highly customizable status line formatter for Claude Code CLI that displays model info, git branch, token usage, and other metrics in your terminal.
          

• Claude HUD by Jarrod Watts - A really stacked status line that exposes just about everything you might need - context usage, tools, agents, todos, etc. Highly configurable and actively maintained at the time of writing - code quality is strong.
          

• claude-code-personalities by kumamaki - A delightfully different status line: 30+ kaomoji text-faces that react in real time to what Claude is doing — context-aware personas by file type, and a frustration-escalation system where mounting errors progress from ( ദ്ദി ˙ᗜ˙ ) toward a table-flip (╯°□°)╯︵ ┻━┻. Pure Rust with sub-2ms rendering, a single binary, hook-based activity tracking, and an interactive config TUI — the standout creative pick in a sea of metrics bars.
          

• claude-powerline by Owloops - A vim-style powerline statusline for Claude Code with real-time usage tracking, git integration, custom themes, and more.
          

• claude-statusbar by leeguooooo - The most complete Claude Code status line: 5-hour and 7-day rate-limit usage with reset countdowns and learned end-of-window projections, context window, prompt-cache-expiry countdown, per-session cost, plus live todo/tool/git activity — across 3 styles and 9 themes, configurable by CLI or natural-language skill. Genuinely well-engineered (PyPI, 320+ tests, a sub-1%-CPU daemon, deep docs) and the clear standout of a very crowded field.
          

• TermaGITchi by TevvvB - A Go CLI that gives each Claude Code session its own creature in the status line, derived by hashing the session id, with one den per git worktree. Where other status-line faces react to what the agent is doing, this one is a stable identity for telling parallel sessions apart, and its expression tracks repository hygiene: uncommitted files, unpushed commits, distance behind trunk and the last test result.
          

• tmux-claude-status-tabs by LiveNL - Shows each Claude Code session's state in the tmux tab bar, per window: an animated spinner while it works, amber when it waits on input, red on a permission request, green when done. Event-driven via hooks with no polling; catches unreported transitions (Esc, permission grants, stop-hook continuations) with transcript watchers. 260+ test assertions run in CI.
          

Design & UI/UX

• Dev Browser by Sawyer Hood - A browser-automation plugin/skill that lets Claude Code drive a browser to test and verify its own work — full Playwright API plus pixel- and DOM-level computer-use toolsets, connecting to your running Chrome or a fresh Chromium. Notably secure and fast: scripts execute inside a QuickJS WASM sandbox with no host filesystem or network access, and a published benchmark shows it beating Playwright MCP on time, cost, and turns.
          

• Diagram Design by Cathryn Lavery - Another welcome contribution to the domain of making Claude Code output look stylish, this collection of skills produces a variety of editorial diagrams in the form of self-contained HTML + SVG. Although I never thought I'd hear these words together, according to the author: "no Mermaid-slop."
          

• Snip by rixinhahaha - A visual whiteboard between you and your agent: Claude renders diagrams, HTML, or UI components through Snip instead of describing them in text, you approve or annotate directly on the output (circle, arrow, note), and the agent gets structured feedback and iterates. Works via CLI or MCP, doubles as a full local screenshot/annotation app with on-device AI organization (Ollama), and adds a genuine human-in-the-loop visual review step to Claude Code.
          

• StyleSeed by kiwiman - A design engine that takes a different tack from "feed the model more tokens": it teaches design judgment — ~74 rules pros carry but never write down ("the refined black isn't #000, it's #2A2A2A"; "one accent color, everything else grayscale") — as plain markdown the agent reads automatically, plus a brand-agnostic skin system, a named motion vocabulary, and /ss-* review skills. Widely adopted and demonstrably effective (a live demo morphs one UI across Toss/Raycast/Arc via a single attribute).
          

• UI Craft by Eduardo Calvo - A deep design-engineering skill that makes agents "design like they have taste" by default, layered so you can just install it, drive it with 22 single-lens commands, or wire its deterministic MCP gates and CLI into CI. Its signature is a scoreable, defensible critique — Nielsen's heuristics × classic design laws × persona walkthroughs, every finding tagged by business impact — backed by anti-slop rules, outcome recipes, accessibility-first review, and 31 domain references.
          

• visual-explainer by nicobailon - Agent skill and plugin that turns complex terminal output into styled HTML pages or slide decks for diagrams, diff reviews, plan audits, data tables, and project recaps. Generates self-contained browser-readable artifacts with Mermaid diagrams, responsive layouts, themes, and sharing commands.
          

• Web Assets Generator Skill by Alon Wolenitz - Easily generate web assets from Claude Code including favicons, app icons (PWA), and social media meta images (Open Graph) for Facebook, Twitter, WhatsApp, and LinkedIn. Handles image resizing, text-to-image generation, emojis, and provides proper HTML meta tags.
          

Writing & Prose Quality

• Avoid AI Writing by Conor Bronsdon - A portable writing skill that audits and rewrites prose to remove "AI-isms" — 49+ pattern categories and a tiered word-replacement vocabulary, with detect / rewrite / edit-in-place modes, content-type and voice profiles, and a two-pass re-check. Stands well above the crowded de-slop field: it ships a deterministic, zero-dependency detector engine (the single source of its 0–100 score) with CI tests, and frames itself honestly as a writing-quality tool, not a detector-evasion gimmick.
          

• Book Factory by Robert Guss - A comprehensive pipeline of Skills that replicates traditional publishing infrastructure for nonfiction book creation using specialized Claude skills.
          

• Claude Style Patch by Andrew Roxby - A CLAUDE.md section that constrains Claude's prose style. It bans specific habits, including announcing a point before making it, colon-hinged sentences where the left side labels the right, verbless fragment openers, and stacked compression. Each rule names the habit, shows an example, and gives the rewrite.
          

• naming by GlacierPhonk - A Claude Code skill for naming products, SaaS tools, brands, and projects via a structured metaphor-driven process — naming brief, metaphor exploration, candidate generation, anti-slop filtering, a weighted evaluation rubric, and availability checks for domains/handles/package names. A genuinely different (and creative) take that produces names grounded in meaning instead of the random tech-syllable mush an unguided model reaches for.
          

Creative Media

• blender-kiln by elithril - A Claude Code plugin that drives Blender over an MCP server to turn a text brief or a reference photo into an optimized, validated GLB: scripted modeling measured against the photo, textures from CC0 scans, a joint-by-joint review, Draco/WebP export.
          

• capcut-cli by René Zander - A zero-dependency Node CLI (and Claude Code plugin/skill) that lets the agent edit CapCut / JianYing video projects programmatically — inspect timelines, build drafts, add text/audio, word-level captions and Whisper transcription, templates, and cut long-form into shorts — JSON in, JSON out, no server. Deeply mature for a media tool: 205 tests across macOS/Windows/Linux CI, a huge documented command surface, and a deliberately stateless "the CLI is the protocol" design.
          

• claude-replay by es617 - An outstanding, creative library that converts Claude Code session transcripts into self-contained, embeddable HTML replays - interactive playback with speed control, a local editor, collapsible tool-call and thinking blocks, redaction for private information - the output is fantastic. Also supports other providers.
          

• motion-skills by iart.ai - An open-source collection of ~50 motion-graphics, animation, and video skills across 14 installable packs — kinetic typography, data-driven charts, explainers, TikTok/Reels, web/WebGL animation, and Manim math animation — that teach an agent how a professional would build each piece. Every visual skill ships a deliver-and-verify loop (render a frame → screenshot → check) plus a small verify toolkit, so the agent inspects its own output instead of guessing at timing and framing.
          

• Vox director skill by Alisa Qian - Vox Director is an open-source skill that turns a one-line topic into a finished Vox-style paper-collage explainer or ad video. It automates the full pipeline — script, collage keyframes, motion, voice-over, music, and captions — on the Atlas Cloud API plus local ffmpeg, with two human approval gates for the beat map and visual style.
          

Infrastructure & DevOps

• cc-devops-skills by akin-ozer - Immensely detailed set of skills for DevOps Engineers (or anyone who has to deploy code, really). Works with validations, generators, shell scripts and CLI tools to create high quality IaC code for about any platform you've ever struggled painfully to work with. Worth downloading even just as a source of documentation.
          

• otelcol-doctor by s3onghyun - A focused, vendor-neutral skill that writes, fixes, and validates OpenTelemetry Collector configs — encoding the Collector's real footguns (memory_limiter/batch ordering, core-vs-contrib components, pull-vs-push exporters, deprecated exporters, pipelines that validate but were never wired) as an authoring workflow and diagnosis checklist. Its standout is honesty plus a verification loop: it always finishes by running otelcol validate and ships CI-checked before/after example configs rather than handing back an unverified file.
          

• terraform-skill by Anton Babenko - A best-practices skill that teaches the agent to write safer Terraform and OpenTofu through a diagnose-first workflow, failure-mode routing, LLM-mistake checklists, and a feature-version guard table mapping features to their version floor and common errors — covering testing, modules, remote state, CI/CD, and security scanning across AWS/Azure/GCP. From an AWS Hero behind the terraform-aws-modules ecosystem, and the most authoritative, most-adopted IaC resource in the set.
