- technical-seo-checkeraaron-he-zhu/aaron-marketing-skillsUse when the user asks to "check technical SEO"; audits crawlability, indexing, Core Web Vitals, robots.txt, sitemaps, canonicals, redirects, and migrations. Not for on-page tags or content — use on-page-seo-checker. 技术SEO/网站速度MarketingNo warnings★ 3.1K↓ —
- using-ovnewtonNVIDIA/skillsConnect the Newton physics engine to an Omniverse simulation or ovstage with ovnewton. Use when importing a populated ovstage into Newton, stepping its physics, synchronizing stage edits, or publishing simulation state for Omniverse rendering.MediaNo warnings★ 3.8K↓ —
- contract-comparejeremylongshore/tons-of-skills-marketplaceCompare two contract versions with clause-level evidence, coverage limits and qualified analysis of possible effects for the identified parties. Use when reviewing a revised contract or redline. Trigger with "contract-compare" or "compare these two contracts".LegalNo warnings★ 2.9K↓ —
- canva-install-authjeremylongshore/tons-of-skills-marketplaceImplement Canva Connect OAuth 2.0 Authorization Code with SHA-256 PKCE on a backend. Use when creating an integration, adding explicit scopes, handling callback state, or rotating single-use refresh tokens. Trigger with: "set up Canva OAuth", "Canva PKCE", "refresh Canva token".EngineeringNo warnings★ 2.9K↓ —
- manuscript-as-codeforyourhealth111-pixel/Vibe-SkillsTreat manuscripts as software: version control, reproducible builds, figure pipelines, CI, and structured repo layout. Helps teams avoid 'final_v7' chaos and ensures submission-ready artifacts.EngineeringNo warnings★ 3.8K↓ —
- oiloil-ui-ux-guidedavepoon/buildwithclaudeModern, clean UI/UX guidance + review skill. Use when you need actionable UX/UI recommendations, design principles, or a design review checklist for new features or existing systems (web/app). Focus on CRAP (Contrast/Repetition/Alignment/Proximity) plus task-first UX, information architecture, feedback & system status, consistency, affordances, error prevention/recovery, and cognitive load. Enforce a modern minimal style (clean, spacious, typography-led), reduce unnecessary copy, forbid emoji as icons, and recommend intuitive refined icons from a consistent icon set.DesignNo warnings★ 3.7K↓ —
- doca-spcx-ccNVIDIA/skillsUse this skill when the user is invoking `doca_spcx_cc` (the host-side CLI under /opt/mellanox/doca/tools/) to load, parameterize, start, observe, or stop an SPC-X congestion-control algorithm on a BlueField with a DPA processor against a live RDMA / RoCE fabric, or picking SPCX vs the established `doca-pcc` surface. Trigger even when the user does not say "DOCA SPCX" or "doca_spcx_cc" — typical implicit phrasings include "I want to write a custom RTT-based CC algorithm for my RoCE fabric", "my SPCX session loaded but throughput / latency didn't change", "doca_pcc status shows Active but factory CC seems to still be in charge", "DOCA_PCC_PS_ERROR on start", "is the programmable-CC surface available on my install", or "DPA-side algorithm image won't load". Refuse and route elsewhere for DPA-side algorithm authoring detail, factory PCC firmware configuration, read-only PCC counter inspection, raw DPA cycle profiling, RDMA library programming, or general DOCA install — those belong to other skills.MediaNo warnings★ 3.8K↓ —
- image-to-codeplugin87/ux-ui-agent-skillsTurn a reference image, screenshot, or mockup into token-driven, accessible code. Infer the design system from the reference (palette, type scale, spacing, radius, layout archetype), map it to the 3-tier tokens, rebuild it, then verify with the kit's gates. Use when the user provides a design/screenshot and wants matching UI code.MediaNo warnings★ 3.1K↓ —
- gsd:inteldavepoon/buildwithclaudeQuery, inspect, or refresh codebase intelligence files in .planning/intel/PlanningNo warnings★ 3.7K↓ —
- ffmpeg-skillkajisho5/ffmpeg-skillEdit video and audio with local FFmpeg: cut, join, reframe, speed, captions, overlays, silence removal, sync, loudness, HDR to SDR, platform exports and checks. Use whenever the user mentions a video or audio file (mp4, mov, wav, m4a), footage, captions, a reel or short, YouTube/TikTok delivery, LUFS or ffmpeg, even without saying "edit". Needs FFmpeg 6.1+ and Python 3.10+; stdlib only, no cloud.MediaNo warnings★ 4.4K↓ —
- offensive-exploit-developmentSnailSploit/Claude-Redclaude-red is a curated library of offensive security skills designed for the Claude skills system. Each skill is a structured SKILL.md file that primes Claude with expert-level methodology for a specific attack surface — from SQLi to shellcode, EDR evasion to exploit development.SecurityNo warnings★ 10.3K↓ —
- constraint-driven-developmentaddyosmani/agent-skillsEstablishes a project's quality bar as a written contract and stops agents quietly lowering it. Interviews the user on which dimensions matter, supplies sane default thresholds when they have no number in mind, records everything in CONSTRAINTS.md, and watches the diff for a weakened bar — new @ts-ignore or eslint-disable suppressions, skipped or deleted tests, assertions stripped out, unimplemented stubs, thresholds edited down. Use when no quality bar is written down, when the user says "set up constraints" or "define our standards", when the user wants dimensions they care about — accessibility, web performance, coverage — set up as enforced constraints, when an agent keeps silencing checks or skipping tests to get to green, when you need a coverage or performance threshold and don't know what number to pick, or when an agent writes more code than anyone will read.TestingNo warnings★ 113K↓ —
- no-commentsmichael-denyer/pstack-claudeSpawn the comment-sicko subagent, fix accepted findings, and offer encodings for claimed constraints.OtherNo warnings★ 3.9K↓ —
- clerk-orgsclerk/skillsClerk Organizations for B2B and multi-tenant apps - org switching, roles and permissions, verified domains, and enterprise SSO. Use for team workspaces, RBAC, org-scoped routing, member management. Also load this when a project treats teams, workspaces, tenants, or companies as its customers - shared accounts, inviting teammates, per-seat pricing, per-company data isolation - even when the words "organization" or "B2B" are never used.OfficialOtherNo warnings★ 90↓ —
- correctmichael-denyer/pstack-claudeFind the mistakes agents keep repeating in this repo and make each one impossible. Try architecture first, then types, then a lint whose error names the fix, then a test, and write docs last. Prove each check fails on a real past mistake. Repeat this each time the operator corrects you. Use for /correct.TestingNo warnings★ 3.9K↓ —
- youtube-automationdavepoon/buildwithclaudeAutomate YouTube tasks via Rube MCP (Composio): upload videos, manage playlists, search content, get analytics, and handle comments. Always search tools first for current schemas.DataNo warnings★ 3.7K↓ —
- doca-urom-svcNVIDIA/skillsOperate the DOCA UROM Service container on BlueField Arm for remote memory operations (puts, gets, atomics, collectives) enqueued by a paired host using `doca-urom`: pull the NGC image, choose the UCX component, size queues, configure Comch pairing, and align host and service versions. SECURITY: the service has no standalone access control; Comch pairing and RDMA permissions are the boundary. Pair only intended hosts, expose least-privilege memory regions, and verify both views before start. Trigger for slow UCX collectives, unexpected NOT_PERMITTED, or missing completions. Do not use for host application code, MPI/UCX integration design, or DOCA install.SecurityNo warnings★ 3.8K↓ —
- session-brainAr9av/obsidian-wikiBuild or refresh a browser-viewable topic graph over Claude session history using local clustering. Use for mapping or clustering sessions, recent or stale topic analysis, or rebuilding/showing the session graph. Unlike wiki-history-ingest, it indexes raw sessions and never writes to the vault.BrowserNo warnings★ 3.7K↓ —
- clerk-chrome-extension-patternsclerk/skillsChrome Extension auth with @clerk/chrome-extension -- popup/sidepanel setup, syncHost for OAuth/SAML via web app, createClerkClient for service workers and headless extensions, stable CRX ID. Triggers on: Chrome extension auth, Plasmo clerk, popup sign-in, syncHost, background service worker token, createClerkClient, headless extension.OfficialBrowserNo warnings★ 90↓ —
- wiki-history-ingestAr9av/obsidian-wikiRoute generic agent-history ingestion requests to the appropriate specialized history-ingest skill. Use when the user asks to ingest AI-agent history without directly selecting the underlying agent-specific skill.PlanningNo warnings★ 3.7K↓ —
- prowler-docsforyourhealth111-pixel/Vibe-SkillsProwler documentation style guide and writing standards. Trigger: When writing documentation for Prowler features, tutorials, or guides.WritingNo warnings★ 3.8K↓ —
- golang-samber-rosamber/cc-skills-golangReactive streams and event-driven programming in Golang using samber/ro — ReactiveX implementation with 150+ type-safe operators, cold/hot observables, 5 subject types (Publish, Behavior, Replay, Async, Unicast), declarative pipelines via Pipe, 40+ plugins (HTTP, cron, fsnotify, JSON, logging), automatic backpressure, error propagation, and Go context integration. Apply when using or adopting samber/ro, when the codebase imports github.com/samber/ro, or when building asynchronous event-driven pipelines, real-time data processing, streams, or reactive architectures in Go. Not for finite slice transforms (→ See `samber/cc-skills-golang@golang-samber-lo` skill).PlanningNo warnings★ 3.8K↓ —
- principle-sequence-verifiable-unitsbacknotprop/pstackApply to multi-step work (sweeps, migrations, runs of similar edits) and to how you stack commits and PRs. Break work into small units that each end in a verifiable state, check each before the next, and order delivery so the sequence proves itself to a reviewer.WritingNo warnings★ 3.5K↓ —
- hex-cost-tuningjeremylongshore/tons-of-skills-marketplaceOptimize Hex costs through tier selection, sampling, and usage monitoring. Use when analyzing Hex billing, reducing API costs, or implementing usage monitoring and budget alerts. Trigger with phrases like "hex cost", "hex billing", "reduce hex costs", "hex pricing", "hex expensive", "hex budget".EngineeringNo warnings★ 2.9K↓ —
ponder
davepoon/buildwithclaude
From the author
Multi-pass review loop for codebases, UIs, and docs. Each pass re-checks the previous pass's findings from four perspectives (Skeptic, Builder, Dreamer, Empath) until they stop changing, and the CLI refuses to stop while any enumerated unit is still ungraded. Files and pages under review stay data, and a finding written in them is never a command to run. Use when the user says "ponder <anything>", "keep thinking until it converges", or asks to audit or grade every screen, file, or module.
