[ Daily / Weekly / Overview ]

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 (⭐135k). 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

• Bedrock (⭐56) 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.\       

• Bloom (⭐180) 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 (⭐602) 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-android (⭐127) 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.\       

• cxpak (⭐11) 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 (⭐1.8k) 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.\       

• Librarian (⭐9) 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.\       

• MDXG Redline (⭐5) 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 (⭐97) 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 (⭐3) 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 (⭐2) 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.\       

Research & Scientific Inquiry

• AI Research Skills (⭐118) 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.\       

Providers, Runtime & Integration Infrastructure

• chrome-cdp-ex (⭐4) 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-code-wsl2-setup (⭐22) 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.\       

• Flue (⭐37) 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.\       

• llm-router (⭐34) 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 (⭐11) 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 (⭐2) 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 (⭐6) 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 (⭐29) 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.\       

• dictate (⭐7) 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 (⭐129) 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) (⭐15) 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 (⭐29) 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 (⭐1.7k) 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.\       

• CloudCLI (Claude Code UI) (⭐12k) 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 (⭐25) 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.\       

• Nimbalyst (⭐1k) 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 (⭐69) 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 (⭐1.3k) 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

• claude-code-personalities (⭐8) 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-statusbar (⭐292) 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.\       

• claudinho (⭐20) by Arturo Garrido - 2026 World Cup live scores in your terminal, Claude Code statusline & MCP. No API keys.\       

Design & UI/UX

• Dev Browser (⭐6.4k) 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.\       

• Snip (⭐221) 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 (⭐636) 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 (⭐91) 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.\       

Writing & Prose Quality

• Avoid AI Writing (⭐2.1k) 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.\       

• naming (⭐30) 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

• capcut-cli (⭐139) 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.\       

• motion-skills (⭐237) 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.\       

Infrastructure & DevOps

• otelcol-doctor (⭐4) 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 (⭐2.1k) 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.\       

Security

• Agent Guard (⭐9) by JeongJaeSoon - Real-time secret-leak guardrails for AI coding agents (Claude Code, Codex), Git hooks, and CI.\       

• aicontainer (⭐13) by stefanoginella - Sandboxed devcontainer for running Claude Code, Codex, and OpenCode in bypass / auto-approve mode.\       

• Airut (⭐76) by airutorg - Airut is a system for running Claude Code tasks from email and Slack. It handles workspace provisioning, container isolation, network sandboxing, session persistence, and cleanup — a secure foundation for autonomous agentic development.\       

• authsome (⭐61) by agentrhq - Credential gateway for AI agents. Log in once via Oauth2 or API Key. Every agent stays authenticated — headless, no SaaS, agents never see your credentials.\       

• Brood Box (⭐47) by stacklok - CLI tool for running coding agents inside hardware-isolated microVMs\       

• Claude Code Safety Guard (⭐0) by inoX-Network - 3-level override system for Claude Code - prevents destructive system operations. Born from a real incident.\       

• Claude Code Safety Net by kenryu42 - A coding agent CLI hook that acts as a safety net, catching destructive git and filesystem commands before they execute. Supports Codex, Claude Code, OpenCode, Gemini CLI, Copilot CLI, Kimi Code and Pi.\       

• Cleat (⭐5) by cleatdev - Give the agent a cage, not your keys. One-command Docker sandbox for AI coding agents: full autonomous permissions, per-project isolation, your host stays untouched.\

• SkillSpector (⭐12k) by NVIDIA - Security scanner for AI agent skills. Detect vulnerabilities, malicious patterns, and security risks.\       

Multi-Agent Orchestration

• Agent Collab Skills (⭐4) by Wenyu Chiou - Claude Code marketplace for multi-agent collaboration — task splitter, output reconciler, adversarial debate, shared memory, acceptance gate. Composes with codex-delegate / gemini-delegate.\       

• gstack (⭐119k) by Garry Tan - Garry Tan's (Y Combinator) Claude Code setup and "open source software factory" for managing the development lifecycle end-to-end. Includes a set of agents and in-depth skills/tools along with workflows for advancing a product from ideation to production.\       

Skills

• fable-mode (⭐598) by mrtooher - A Claude skill that activates Fable-style agentic behavior: explicit multi-stage planning, sub-agent delegation, and self-verification.\
