- landing-page-generatorkostja94/marketing-skillsDeprecated compatibility entry for Landing Page construction. This page is now maintained in Pagina; install and use page-builder to build a new Landing Page.DesignNo warnings★ 1.1K↓ —
- design-system-compliancereticlehq/reticleCheck that the UI you actually rendered uses the design system, by reading computed styles in the running app against the project's design tokens. Catches hardcoded hex colors, off-palette backgrounds, invisible or unusable controls, and animations that never ran. Use after building or restyling a component, when a design review is wanted, when a UI looks slightly off but nobody can say why, or when a design system exists and nothing checks whether the code follows it.DesignNo warnings★ 1.2K↓ —
- 00-arena-routeragentscope-ai/OpenJudgeUse when the user wants to compare or benchmark multiple LLMs/agents arena-style but it's unclear which specific workflow fits — a general-purpose win-rate comparison on a custom task, or a benchmark specifically about reference/citation hallucination rate. Also use when the user mentions model arena, agent arena, pairwise model comparison, win-rate ranking, or comparing models on a task and hasn't specified whether that task is generic or about citation accuracy. This skill is the entry router for the arena-eval suite: it asks one diagnostic question when needed, then recommends the workflow or workflows needed to cover the request.PlanningNo warnings★ 1.1K↓ —
- dependency-managementrampstackco/claude-skillsManage third-party libraries, runtimes, and SaaS dependencies. Use this skill when setting an update cadence, responding to security advisories, dealing with deprecated dependencies, evaluating new dependencies, auditing what's installed, or unblocking a dependency upgrade. Triggers on dependency, package update, security patch, lockfile, deprecated, breaking change, supply chain, dependency audit, npm audit, dependabot, renovate. Also triggers when a build breaks after an update or when an advisory is published for a used package.SecurityNo warnings★ 1K↓ —
- add-mnemonnanocoai/nanoclawAdd persistent graph-based memory via mnemon. Agents recall past context before responding and remember insights after each turn.ProductivityNo warnings★ 31.1K↓ —
- grantsalirezarezvani/claude-skillsUse for any NIH funding question ('find grants for my research', 'which NIH institute'). Maps the idea to institutes, study sections and NOSIs via RePORTER, matches mechanisms with mechanism_matcher.py and writes a .docx strategy. NIH only.DocumentsNo warnings★ 29.3K↓ —
- anomaly-alerthoangsonww/Claude-Code-Agent-MonitorIdentify anomalous sessions using Agent Monitor data — cost outliers from the pricing engine, token anomalies (cache miss spikes, compaction baseline surges), unusual event type ratios (PreToolUse/PostToolUse gaps, APIError clusters), behavioral deviations from workflow intelligence (complexity score outliers, error propagation anomalies), and sessions with abnormal metadata (extreme turn_count, high thinking_blocks, zero turn_duration).ProductivityNo warnings★ 1.1K↓ —
- orchestrating-agent-relayAgentWorkforce/relayThe canonical way to run agent-relay - self-bootstrap the local broker and autonomously spawn, monitor, and coordinate a team of worker agents without human intervention. Covers infrastructure startup, agent spawning, lifecycle monitoring, message-based reading via the relay MCP, and team coordination.DevOpsNo warnings★ 1.1K↓ —

- tdd-workflowmohitagw15856/pm-claude-skillsDrive a feature with a disciplined test-driven development loop — red, green, refactor. Use when implementing a feature or fixing a bug and you want tests to lead, or when asked to 'do this with TDD' / write the test first. Produces a step-by-step red-green-refactor plan: the failing test to write first, the minimal code to pass it, and the refactor — one small cycle at a time.TestingNo warnings★ 1.5K↓ —
- threat-modelmohitagw15856/pm-claude-skillsThreat-model a system or feature to find where it could be attacked, before you build it. Use when asked to threat-model, do a security design review, document security risks, identify attack surface, or apply STRIDE to a design. Produces a structured threat model: assets, trust boundaries and data flows, threats enumerated by category (STRIDE), risk scores, prioritized mitigations, and residual-risk sign-off. Defensive security for systems you own or are authorized to assess.SecurityNo warnings★ 1.5K↓ —
- verify-unattendedreticlehq/reticleInstall, instrument and verify a web app end to end without pausing for a human. Use in an autonomous or goal-mode agent, in CI, or in any client that asks for approval on every command: it never says "restart your client" or "open a browser", because it takes a route that needs neither. Prefer the normal reticle skill when a human is present and can answer.BrowserNo warnings★ 1.2K↓ —
- wiki-summarymohitagw15856/pm-claude-skillsFetch Wikipedia's current summary of any topic with zero API keys — the REST summary endpoint via curl, for answers that need today's article rather than training-data memory. Use when asked what does Wikipedia say about X, get me the current summary of a topic, check a fact against Wikipedia, or has this article changed. Produces the live extract with the article link, disambiguation handling, and a clean separation between what Wikipedia says and what the model adds.ProductivityNo warnings★ 1.5K↓ —
- app-adskostja94/marketing-skillsWhen the user wants to run app install ads, user acquisition (UA), or promote mobile apps. Also use when the user mentions "app ads," "app install ads," "UA," "user acquisition," "Google App Campaigns," "Apple Search Ads," "ASA," "UAC," "App Store ads," "Play Store ads," "CPI," or "app promotion." For store listings, use distribution-channels.MarketingNo warnings★ 1.1K↓ —
- 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↓ —
- media-asset-managementrampstackco/claude-skillsPlan and run a media pipeline for images, video, and downloadable assets. Use this skill when designing image storage and delivery, choosing formats (WebP, AVIF), setting up responsive images, picking a video host, organizing a brand asset library, or auditing a slow image pipeline. Triggers on image pipeline, asset library, DAM, image optimization, WebP, AVIF, responsive images, video hosting, image CDN, asset workflow, media management. Also triggers when images are slow, broken, or scattered across systems.MediaNo warnings★ 1K↓ —
- setup-app-insightsmicrosoft/power-platform-skillsConfigure optional customer-owned Application Insights telemetry for a Power Apps mobile app — enable it against an existing Azure resource, change the resource, or disable it. Standalone, and invoked by /edit-app.DevOpsNo warnings★ 1.1K↓ —
- analyticsmicrosoft/power-platform-skillsUse when a Process Mining overview, initial process selection, or an analytical follow-up needs routing.DataNo warnings★ 1.1K↓ —
- arenaNewhashgraph-online/awesome-codex-pluginsSeveral subagents build the same artifact from one brief in isolation, a read-only judge scores them, and you pick a base and graft in the best parts of the rest. Use for "arena this", "competing attempts", "second opinion on this approach".OtherNo warnings★ 1.5K↓ —
- holoscan-install-debianNVIDIA/skillsInstall Holoscan SDK 5.x native C++ Debian packages on Ubuntu 24.04, choosing the full SDK or matching modular packages.OtherNo warnings★ 3.9K↓ —
- cover-lettermohitagw15856/pm-claude-skillsWrite a specific, non-generic cover letter that connects your evidence to the role. Use when asked to write a cover letter, an application letter, or a note to accompany a resume. Produces a tight 3–4 paragraph letter — a real hook, two evidence paragraphs mapping your proof to the job's needs, and a confident close — tailored to the company, ready to export as a designed PDF.DocumentsNo warnings★ 1.5K↓ —
- go-to-marketmohitagw15856/pm-claude-skillsCreate go-to-market assets for any product or feature. Use when asked for a GTM plan, positioning statement, product launch plan, messaging pillars, use cases, or feature/benefit list. Produces a full GTM pack: positioning statement, messaging pillars, feature-to-benefit mapping, and role-specific use cases. For a tiered launch plan with cross-functional coordination use go-to-market-planner instead.PlanningNo warnings★ 1.5K↓ —
- oauthhashgraph-online/awesome-codex-pluginsUse when a val needs to require login with a Val Town account — gating routes behind authentication, identifying the current user, building user-specific dashboards. Covers std/oauth's `oauthMiddleware` and `getOAuthUserData`, the auto-managed `/auth/*` routes, and session behavior. For third-party OAuth providers (Google, GitHub, etc.) see the `third-party-integrations` skill instead.PlanningNo warnings★ 1.5K↓ —
- cloudrun-developmentTencentCloudBase/CloudBase-AI-ToolkitCloudBase Run backend development rules (Function mode/Container mode). Use this skill when deploying backend services that require long connections, multi-language support, custom environments, AI agent development, or migrating existing/GitHub apps that need VPC access to MySQL/PostgreSQL/Redis. Also use when diagnosing CloudRun container deploy failures (deploy_failed, readiness/probe failed, image won't start, docker.io pull loops) or a deploy stuck behind a running deploy task. For stateless HTTP services, prefer HTTP cloud functions.DevOpsNo warnings★ 1.2K↓ —Also in 5 other repos
