- brooks-testhyhmrright/brooks-lintTest quality review drawing on twelve classic engineering books — with primary focus on xUnit Test Patterns, The Art of Unit Testing, How Google Tests Software, and Working Effectively with Legacy Code — that diagnoses structural problems in an existing test suite: brittleness, mock abuse, coverage illusions, slow execution, poor readability. Triggers when: user asks about test quality, shares test files for review, or expresses frustration: "tests keep breaking whenever I change anything", "our tests take forever", "tests pass but bugs still reach production", or "we have too many mocks". Do NOT trigger for: writing new tests from scratch (use the regular test-writing workflow) or testing framework/syntax questions — this skill reviews an existing suite for structural quality problems, not individual test authoring.TestingNo warnings★ 1.6K↓ —
- hook-diagnosticshoangsonww/Claude-Code-Agent-MonitorDiagnose Claude Code hook installation, delivery, and ingestion issues. Checks hook configuration, connectivity, event flow, and identifies common problems. Use when events are not appearing in the dashboard.EngineeringNo warnings★ 1.1K↓ —
- minutes-weeklysilverstein/minutesWeekly meeting synthesis — themes, decision arcs, stale commitments, and what deserves your attention next week. Use when the user says "weekly review", "what happened this week", "weekly summary", "recap my week", "any outstanding items", "week in review", or at the end of a work week.EngineeringNo warnings★ 1.6K↓ —Also in 1 other repo
- wake-traceamplifthq/openmeldUse when diagnosing a Wake that failed, stalled, or produced no visible reply — dispatch, setup handoff, or reply-path issues. Routes to the deterministic trace evidence path.OtherNo warnings★ 1.4K↓ —
- appllama-app-design-skillAppllama/appllama-skillsBuild native-feeling, benchmark-quality mobile app screens (Expo / React Native). Use when designing or implementing any mobile UI — screens, flows, onboarding, paywalls, tab bars, sheets, settings, empty states — or when polishing motion, navigation, typography, dark mode, or perceived performance. Enforces Apple HIG fidelity, semantic colors, native controls, anti-slop discipline, navigation semantics (push vs replace, modal vs sheet vs overlay, the one-way doors where back must not exist), purposeful Reanimated motion, a full-motion simulator-verified iteration loop, and a study-real-apps-first workflow (pairs with the Appllama MCP). Trigger on "build a screen", "make this screen better", "design the onboarding", "wire up this flow", "polish the UI", "make it feel native", or any mobile design/implementation task.DesignNo warnings★ 4K↓ —
- demand-lettermohitagw15856/pm-claude-skillsDraft a firm, professional demand letter that states the facts, the legal/contractual basis, the specific demand, and a deadline. Use when asked to write a demand letter, send a formal demand for payment, draft a cease-and-desist, or formally request resolution before legal action. Produces a structured, factual letter with a clear ask and consequences — assertive but not threatening or defamatory. Not legal advice; have counsel review before sending.LegalNo warnings★ 1.5K↓ —
- brooks-audithyhmrright/brooks-lintArchitecture audit that maps module dependencies, checks layering integrity, and flags structural decay across a codebase, drawing on twelve classic engineering books. Triggers when: user asks to audit architecture, review folder/module structure, check for circular imports, understand how the codebase is organized, or asks "does this follow clean architecture?" or "why does everything depend on everything?". Also triggers for onboarding requests: "explain this codebase to a new developer" or "give me a codebase tour" (use onboarding mode). Do NOT trigger for: PR-level code review (use brooks-review) or line-level refactoring questions — this skill analyzes structural/module-level concerns, not individual functions.PlanningNo warnings★ 1.6K↓ —
- handoff-specdzhng/skillsHand a spec that is mid-implementation to another machine or another agent.PlanningNo warnings★ 1.4K↓ —
- ui-designUpdatedTencentCloudBase/CloudBase-AI-ToolkitUse when users need visual direction, interface hierarchy, layout decisions, design specifications, or prototypes before implementing a Web or mini program UI.DesignNo warnings★ 1.2K↓ —Also in 5 other repos
- ai-feature-prdmohitagw15856/pm-claude-skillsWrite a PRD for an AI-powered feature, covering the things normal PRDs miss. Use when asked to spec an AI/LLM feature, write a PRD for a feature that uses a model, or plan an AI capability (assistant, summarizer, generator, classifier). Produces an AI feature PRD — problem & UX of uncertainty, model approach, eval criteria, guardrails, fallback behaviour, the data flywheel, and cost/latency budget.PlanningNo warnings★ 1.5K↓ —
- jetson-customize-clocksNVIDIA/skillsUse to lock/cap Jetson CPU/GPU/EMC clocks, toggle EMC/CPU DVFS, or change cpufreq governors by editing BPMP DTB and nvpower.sh pre-flash. Do NOT use for live tuning or nvpmodel edits.WritingNo warnings★ 3.8K↓ —
- blueprinthashgraph-online/awesome-codex-pluginsTurn a one-line objective into a step-by-step construction plan for multi-session, multi-agent engineering projects. Each step has a self-contained context brief so a fresh agent can execute it cold. Includes adversarial review gate, dependency graph, parallel step detection, anti-pattern catalog, and plan mutation protocol. TRIGGER when: user requests a plan, blueprint, or roadmap for a complex multi-PR task, or describes work that needs multiple sessions. DO NOT TRIGGER when: task is completable in a single PR or fewer than 3 tool calls, or user says "just do it".PlanningNo warnings★ 1.5K↓ —
- analyze-performancegooseworks-ai/goose-skillsWeekly performance read across every channel we run: what worked, why, and what to make next, judged on the business's real number (store revenue, qualified pipeline, retained users), not platform claims. Use when: write my Monday report; how are my ads doing — which ad won?; are my ads actually making money (Meta says 4x ROAS but revenue is flat); why did sales drop this week; did the test win; is my tracking working; monthly numbers for the replan; anything on fire today. Not for acting on the recommendations (pausing, scaling, launching) — use run-paid-campaigns; not for replanning the budget — use plan-campaign.TestingNo warnings★ 1.3K↓ —
- brooks-reviewhyhmrright/brooks-lintPR code review that surfaces decay risks, design smells, and maintainability issues with concrete Symptom → Source → Consequence → Remedy findings, drawing on twelve classic engineering books. Triggers when: user asks to review code, check a PR, shares a diff or pastes code asking "does this look right?" / "any issues here?" / "ready to merge?", or asks for feedback on a function, class, or file. Also triggers when user mentions: code smells / refactoring / clean architecture / DDD / SOLID principles / Hyrum's Law / deep modules / tactical programming / conceptual integrity / Brooks's Law / Mythical Man-Month / second system effect. Do NOT trigger for: questions about how to write code from scratch, language syntax questions, or framework/tool questions where no existing code is shared.EngineeringNo warnings★ 1.6K↓ —
- research-market-listeninggooseworks-ai/goose-skillsStep of the research-market playbook: the worker brief for listening to what people say about the brand and category, risks first. Run research-market instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- auth-web-cloudbaseUpdatedTencentCloudBase/CloudBase-AI-ToolkitCloudBase Web Authentication Quick Guide for frontend integration after auth-tool has already been checked. Provides concise and practical Web authentication solutions with multiple login methods and complete user management.DesignNo warnings★ 1.2K↓ —Also in 4 other repos
- read-the-roommohitagw15856/pm-claude-skillsFigure out the real social dynamics of a situation — the unspoken mood, who holds influence, what's actually going on beneath the surface — so you respond to what's real, not just what's said. Use when asked help me read this situation, what's really going on here, how should I play this socially, or I can't tell the vibe. Produces an interpretation of the likely dynamics from your description (the mood, the power/influence, the unspoken tensions, what people actually want), how to check your read, and how to adjust your approach — with a caution against over-reading and a nudge to verify rather than assume.OtherNo warnings★ 1.5K↓ —
- conversion-optimizationkostja94/marketing-skillsWhen the user wants to improve conversion rates, run A/B tests, optimize funnels, or reduce friction. Also use when the user mentions "CRO," "conversion rate optimization," "A/B test," "split test," "funnel optimization," "checkout optimization," "form optimization," or "conversion funnel." For pricing psychology, use pricing-strategy.MarketingNo warnings★ 1.1K↓ —
- expense-auditmohitagw15856/pm-claude-skillsAudit spending to find leaks — recurring subscriptions, creep, and cuttable costs — ranked by impact. Use when asked to cut expenses, review subscriptions, find where money is going, or free up cash. Produces a categorized spend breakdown, a ranked list of cuts with dollar amounts, and the annualized savings. Educational, not regulated financial advice.FinanceNo warnings★ 1.5K↓ —
- rendering-strategieskostja94/marketing-skillsWhen the user wants to choose or optimize rendering strategy for SEO. Also use when the user mentions "SSR," "SSG," "CSR," "ISR," "static rendering," "dynamic rendering," "server-side rendering," "client-side rendering," "JavaScript rendering," "pre-rendering," "prerender," "content in initial HTML," or "crawler visibility." For crawl issues, use site-crawlability.MediaNo warnings★ 1.1K↓ —

- write-specdzhng/skillsBreak large features into independently verifiable, human-reviewable slices under a feature directory in specs/. Use for risky or multi-step feature work that needs upfront questioning, API seams, browser-playable checkpoints, HTML visualizations, screenshot gates, staged implementation plans, recursive fog-of-war reslicing, or proactive research into reference implementations/best practices before slicing. Pairs with your project's verification harness and screenshot gates (the browser checkpoints), [refactor-clean](../refactor-clean/SKILL.md) (review the materialized spec so the plan describes one-owner architecture, not the feature bolted on), [screenshot-critique](../../visual/screenshot-critique/SKILL.md) and [compare-screenshots](../../visual/compare-screenshots/SKILL.md) (the visual gates), and a code-review pass (audit each slice before it lands).WritingNo warnings★ 1.4K↓ —
- keyword-researchkostja94/marketing-skillsWhen the user wants to research keywords, find target keywords, or analyze search intent. Also use when the user mentions "keyword research," "keyword tool," "target keywords," "search volume," "search intent," "keyword difficulty," "topical map," "keyword clustering," "People Also Ask," "Google autocomplete," "autocomplete keywords," or "alphabet method." For clusters, use content-strategy.ScienceNo warnings★ 1.1K↓ —
