- architectNewhashgraph-online/awesome-codex-pluginsSettle structure before writing logic. Ground in the current code, get competing design sketches (types, signatures, modules, trust boundaries) through arena, implement against the merged sketch, scrap it on a friction pattern. Use for "architect this", "design X first".PlanningNo warnings★ 1.5K↓ —
- claude-authenticityagentscope-ai/OpenJudgeDetect whether an API endpoint is backed by genuine Claude (not a wrapper, proxy, or impersonator) using 9 weighted rule-based checks that mirror the claude-verify project. Also extracts injected system prompts from providers that override Claude's identity. Fully self-contained — copy the code below and run, no extra packages beyond httpx. Use when the user wants to verify a Claude API key or endpoint, check if a third-party Claude service is authentic, audit API providers for Claude authenticity, test multiple models in parallel, or discover what system prompt a provider has injected.TestingNo warnings★ 1.1K↓ —
- improve-search-visibility-store-listing-auditgooseworks-ai/goose-skillsAudits an app's App Store and Google Play listing against three competitors (title, subtitle, description opening, first screenshots and captions, rating, review themes) and writes a field-by-field rewrite with character counts, or a launch-day listing before release. Use alone when you already have the app's store links and signed-off product facts; otherwise run improve-search-visibility.WritingNo warnings★ 1.3K↓ —
- false-green-testsreticlehq/reticleFind out why the tests pass but the app is broken. Catches false greens: a green suite over a feature that does not work, a mocked API standing in for a real one, an assertion that holds no matter what the app does, a click handler wired to nothing. Use when the suite is green and the user says it is broken, when a test never fails, when coverage looks fine but bugs still ship, or before trusting a passing run you did not watch.TestingNo warnings★ 1.2K↓ —
- postgresql-development-cloudbaseUpdatedTencentCloudBase/CloudBase-AI-ToolkitUse when building, debugging, or evaluating CloudBase PostgreSQL / CloudBase PG / PG mode apps, including Postgres schema setup, queryPgDatabase/managePgDatabase, JS SDK v3 app.rdb() CRUD/RPC, PG HTTP API fallback, RLS-style permissions, username-password auth, and Web CMS/admin CRUD flows backed by CloudBase PG.DataNo warnings★ 1.2K↓ —Also in 4 other repos
- subagentevo-hq/evoProtocol that evo optimization subagents follow when dispatched from /optimize. Auto-loaded by spawned subagents via their host's skill loader. The orchestrator may also invoke this skill to understand the brief shape its dispatched subagents expect + what they're required to emit -- useful when writing briefs or debugging a subagent's behavior.WritingNo warnings★ 1.5K↓ —Also in 1 other repo
- red-teamalirezarezvani/claude-skillsUse when planning or running an authorized red team engagement or attack path analysis. Plans the kill chain with engagement_planner.py: MITRE ATT&CK techniques, choke points, OPSEC risk and crown jewels.PlanningNo warnings★ 29.3K↓ —
- setting-up-relayfileAgentWorkforce/relayUse when an agent or human needs to set up relayfile end-to-end so agents can read and write provider files through a local mount. Covers `relayfile setup`, dynamic integration discovery with `relayfile integration available/search`, Nango and Composio backend selection, Atlassian site selection and metadata, cloud login, OAuth/connect flows, mount verification, `RELAYFILE_LOCAL_DIR` handoff, writeback status and retry commands, and key May 2026 cloud-mount gotchas.WritingNo warnings★ 1.1K↓ —
- varg-music-videohashgraph-online/awesome-codex-pluginsDirects an AI music video or a song-driven promo end to end on varg, the way the most-watched AI music videos are made: measure the song (beat grid, word timings), pitch the concept, cast and lock character references, storyboard every cut on a downbeat, approve stills before paying for video, generate Seedance 2.5 shots, run a mandatory lip-sync pass, draw lyrics and graphics in code, run review rounds and master for each platform. Use when someone asks for a music video, a clip for my song, a video for a track, a lyric video with AI footage, a singing character, an AI artist or band video, slopcore, or a launch video cut to a song. Not for a one-off generated song or single clip (use varg-ai), shot planning and 3D camera blocking only (use varg-previz), a talking character without music (use varg-character-keynote or varg-podcast-video), or a typography-only lyric video with no generated footage (use a HyperFrames music-to-video skill).MediaNo warnings★ 1.5K↓ —
- baoyu-slide-deckJimLiu/baoyu-skillsGenerates professional slide deck images from content. Creates outlines with style instructions, then generates individual slide images. Use when user asks to "create slides", "make a presentation", "generate deck", "slide deck", or "PPT".DocumentsNo warnings★ 27.3K↓ —
- brag-docmohitagw15856/pm-claude-skillsKeep a running brag document of your accomplishments so reviews and promo cases write themselves. Use when asked to start or update a brag doc, log a win, track accomplishments, or prep evidence for a review/promotion. Produces a structured, dated accomplishment log — impact-first entries with metrics, scope, and the evidence link — grouped so it drops straight into a self-review or promo packet.WritingNo warnings★ 1.5K↓ —
- varg-video-editinghashgraph-online/awesome-codex-pluginsWhich service to edit an existing video with, and how to edit it without breaking it. A routing guide for ten editing jobs: cut, trim, resize and join (FFmpeg, Rendi), talking-head cleanup (silence and filler cuts), long video to Shorts (OpusClip, or transcript + FFmpeg), captions and subtitles (ASS through FFmpeg, HyperFrames, Submagic), assembling from a timeline or template (HyperFrames, Shotstack), AI edits that restyle, swap people, relight or extend (varg Recast/Relight, Runway Aleph), dubbing and lip sync (HeyGen, ElevenLabs, Sync Labs), upscaling, slow motion and background removal (Topaz, Bria), finding moments and QA (Gemini, Twelve Labs), and handing off to Resolve, Premiere or Final Cut. Use when someone asks to edit, cut, trim, shorten, clip, reframe, caption, subtitle, translate, dub, lip-sync, upscale, restyle or clean up footage they already have, or asks which tool or API to edit video with. Not for making a video from a brief (varg-ai and the format skills).MediaNo warnings★ 1.5K↓ —
- product-video-hookshashgraph-online/awesome-codex-pluginsTurn a product into scroll-stopping video hooks. Writes the first 3 seconds of TikTok, Reels and Meta product videos as three agreeing layers (what is on screen, the spoken line, the text overlay), from the buyer's own words, across 20+ hook types taken from Meta's Hooks Menu, Motion's 2026 hook data, Hormozi's callouts and the TikTok openers that spread in 2026 (late discovery, compliment then reveal, problem and fix in one clip, reply to a comment). It matches each hook to the buyer's awareness, checks it against platform claim rules, and, when footage exists, makes one MP4 per hook for testing. Use when someone asks for hooks, openers, the first 3 seconds, a better intro, or new hook variants for a product video or ad. NOT for whole ad plans (use ecommerce-video-ads), generating a viral-style product-in-use hook clip from photos (use varg-product-hook), app or SaaS hooks, or YouTube titles and thumbnails.MediaNo warnings★ 1.5K↓ —
- asc-testflight-orchestrationrorkai/app-store-connect-cli-skillsOrchestrate TestFlight distribution, groups, testers, and What to Test notes using asc. Use when rolling out betas.TestingNo warnings★ 1.1K↓ —
- rfp-responderalirezarezvani/claude-skillsUse when an RFP, RFI, RFQ or security or vendor questionnaire arrives. Parses mandatory vs weighted requirements with rfp_parser.py, drafts proof-point answers with response_drafter.py and estimates win chance with winrate_predictor.py.SecurityNo warnings★ 29.3K↓ —
- verify-form-validationreticlehq/reticleCheck that a form actually rejects bad input: the error message renders, the submit button stays disabled, and no request goes out. Use when validation logic was written but never driven, when a "required" or pattern check looks right on screen but was never proven, or when a bug report says the form submitted invalid data anyway.MediaNo warnings★ 1.2K↓ —
- asc-screenshot-resizerorkai/app-store-connect-cli-skillsResize and validate App Store screenshots with current asc screenshot-size data and macOS sips. Use when preparing or fixing screenshots for App Store Connect submission.OtherNo warnings★ 1.1K↓ —
- oma-voiceUpdatedfirst-fluke/oh-my-agentGenerate or transcribe speech with Voicebox or VoiceStudio, or process existing audio locally. Use for narration, transcripts, timed speech, and loudness conversion; video editing uses oma-video.MediaNo warnings★ 1.4K↓ —Also in 2 other repos
- writing-relayflowsAgentWorkforce/relayUse when authoring a Relayflows flow (@relayflows/surface / @relayflows/sdk, the journal-based v2 engine — the CLI is `flows`, package versions 2.0.x) in TypeScript or YAML/JSON. Covers the three-rung ladder (run/llm/agent), the resident verbs (human/dispatch/done), verification gates, TypeScript vs YAML authoring, per-step cli/model selection and its resolution order, flows.json, and `flows check`/`run`/`resume` with their real refusal shapes and exit codes. Not for the older, unrelated `@relayflows/core` WorkflowBuilder engine (`.pattern('dag')`/.agent()/.step() chains) that `writing-agent-relay-workflows` and `migrating-persona-to-relayflow` cover — that's a different product despite the similar name.WritingNo warnings★ 1.1K↓ —
- scheduler-and-booking-designrampstackco/claude-skillsDesigning meeting schedulers and booking experiences that qualify leads, set up calls well, and convert at higher rates than a generic Calendly link. Availability logic, qualification gating, prep automation, follow-up sequencing. Honest about any-time-friction (no qualification, just a booking link), interrogation-gate (so much qualification it scares users off), and qualified-fast-path (just enough qualification to set up the call well) patterns. Triggers on scheduler design, meeting booking, demo scheduling, sales call scheduling, calendar tool, booking page, qualification flow. Also triggers when sales team complains about cold demos, when booking conversion is poor, or when scheduler is being scoped for the first time.DesignNo warnings★ 1K↓ —
- token-dietmohitagw15856/pm-claude-skillsCut LLM output tokens 40–70% by stripping grammatical scaffolding while preserving every fact — telegraphic output modes, when they pay (pipelines, long sessions) and when they don't (single shots, human-facing prose), with the mode lines to switch on demand. Use when asked make the model respond tersely, cut output token costs, caveman mode, or compress agent-to-agent messages. Produces the diet-mode instruction block ready to paste, the three compression levels with examples, the economics of when each pays, and the never-diet list.WritingNo warnings★ 1.5K↓ —
- oma-coordinationfirst-fluke/oh-my-agentGuide for coordinating PM, Frontend, Backend, Mobile, and QA agents on complex projects via CLI. Use for manual step-by-step coordination and workflow guidance.TestingNo warnings★ 1.4K↓ —
- add-codexnanocoai/nanoclawUse Codex (OpenAI's codex app-server) as a full agent provider — planning, tool orchestration, MCP tools, server-side history, session resume — alongside or instead of Claude. ChatGPT subscription or OpenAI API key, vault-only via the selected gateway. Per-group via `ncl groups config update --provider codex`. Distinct from using OpenAI as an MCP tool (where Claude remains the planner).PlanningNo warnings★ 31.1K↓ —
- webhook-managementhoangsonww/Claude-Code-Agent-MonitorConfigure and validate CCAM webhook targets across supported chat, incident, automation, and generic providers. Use when listing provider requirements, creating or updating a target, scoping it to alert rules, sending a test notification, reviewing delivery history, or deleting a target.TestingNo warnings★ 1.1K↓ —
