- experimentation-analyticsrampstackco/claude-skillsHow to read experiment results without fooling yourself. Confidence intervals, p-values, multiple testing, sequential testing, CUPED, heterogeneous treatment effects, ratio metrics, network effects, dashboard reconciliation, and the interpretation failures that produce confidently wrong shipping decisions. Use this skill whenever the user is reading a finished experiment result panel and about to make a ship, kill, or iterate decision, or when an experiment number does not match the dashboard number. Triggers on read experiment results, result panel, ship or kill decision, p-value, confidence interval, statistical significance, multiple testing, peeking, sequential testing, CUPED, variance reduction, heterogeneous treatment effects, ratio metric, network effects, inconclusive test, experiment versus dashboard mismatch. Use `experiment-design` instead when the test has not run yet and the question is hypothesis, sample size, duration, or what to test.DataNo warnings★ 1K↓ —
- scrapecreators-apigooseworks-ai/goose-skillsProvider reference for collecting public profiles, posts, comments, transcripts, trends, and ad-library data from major social platforms through ScrapeCreators. Use as a dependency of research workflows, not as the final user-facing deliverable.BrowserNo warnings★ 1.3K↓ —
- database-designCloudAI-X/claude-workflow-v2Designs database schemas, indexing strategies, query optimization, and migration patterns for SQL and NoSQL databases. Use when designing tables, optimizing queries, fixing N+1 problems, planning migrations, or when asked about database performance, normalization, ORMs, or data modeling.DataNo warnings★ 1.4K↓ —
- executing-plansGanyuanRan/AegisUse when executing a written implementation plan across sessions or with review checkpoints. Small or single-slice plans stay inline. For same-session independent tasks, use subagent-driven-development instead.PlanningNo warnings★ 1.4K↓ —
- entity-seokostja94/marketing-skillsWhen the user wants to optimize for entity recognition, Knowledge Graph, or entity-based SEO. Also use when the user mentions "entity SEO," "entity optimization," "Knowledge Graph," "Knowledge Panel," "entity signals," "brand entity," "entity linking," "entity relationships," or "entity-first content." For structured data, use schema-markup.MarketingNo warnings★ 1.1K↓ —
- readyhashgraph-online/awesome-codex-pluginsUnderstand what you mean before anything is built. Takes anything — a one-line idea, notes, a spec, or a mix — reads the project first, asks only what is yours to decide, and writes your intent down for you to approve. Use when the user invokes the `ready` skill. Requires git.WritingNo warnings★ 1.5K↓ —Also in 3 other repos
- harvesthuytieu/COG-second-brainCapture durable session learnings, stage for human promotion to 05-knowledge/lizard, and propose skill/CLAUDE.md patches. Triggered by /harvest, SessionEnd hook staging, or nightly enhance. Never writes durable knowledge without your approval.WritingNo warnings★ 1.3K↓ —Also in 1 other repo
- plain-writingNewhashgraph-online/awesome-codex-pluginsMakes every report a Mobbin skill writes read like a person wrote it, in plain interface terms. Use only when a Mobbin skill writes prose for the user or asks for this skill by name; not for writing outside Mobbin skills. Removes the tells of AI-generated writing (em dashes, puffery, design buzzwords, rule-of-three, sign-offs) without changing a fact or adding one.WritingNo warnings★ 1.5K↓ —
- writing-testsamplifthq/openmeldGates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before any change to what a pytest, Jest, or Playwright test asserts or sets up, down to one fixture or one assertion added to an existing block. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; extend the nearest existing test before writing a new standalone one; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network; no time bombs from absolute dates left to age against the real clock; no database a test never uses). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.TestingNo warnings★ 1.4K↓ —
- minutes-x1-send-meetingsilverstein/minutesSend one of the user's own Minutes meetings to their X1 household for review. Use when the user wants a meeting's summary, decisions, action items, and open questions to reach X1 so they can confirm what belongs in their household record. X1 asks the user to approve the send, and nothing reaches the household record until they confirm each item. Never use it for a restricted meeting, a transcript, or someone else's meeting.EngineeringNo warnings★ 1.6K↓ —Also in 1 other repo
- writing-plansGanyuanRan/AegisUse when you have an approved spec or written requirements for a multi-step task that needs a durable plan document before touching code. Small, single-owner, or fast-path tasks do not need this skill.WritingNo warnings★ 1.4K↓ —
- sprint-summaryhoangsonww/Claude-Code-Agent-MonitorSummarize a sprint's worth of Claude Code activity — sessions grouped by project (cwd), per-model cost breakdown, token efficiency (cache hit rate, compaction baselines), subagent effectiveness from workflow API, velocity metrics (turn_count, turn_duration_ms), and tool diversity across the sprint.ProductivityNo warnings★ 1.1K↓ —
- design-with-imagesdzhng/skillsExplore UI and visual design with image generation, then iterate the real implementation against the user-selected concept. Use when brainstorming visual directions, offering mockup variants, or implementing an approved generated design; do not stop at the mockups or the first code approximation.DesignNo warnings★ 1.4K↓ —
- ap-roadmap-authorSpielewoy/autoprompt-skillWrite one dependency-ordered roadmap with owners, integration points, success items, and real checks.PlanningNo warnings★ 1.2K↓ —
- senior-fullstackalirezarezvani/claude-skillsStart a fullstack project or audit a codebase: pick a stack (Next.js, FastAPI, MERN, Django), scaffold it and score code quality. Use whenever the user asks which stack to use, wants a new web app set up, or asks how good or messy their codebase is.EngineeringNo warnings★ 29.3K↓ —
- cost-breakdownhoangsonww/Claude-Code-Agent-MonitorBreak down Claude Code costs using the Agent Monitor pricing engine. Shows per-model costs (input, output, cache_read, cache_write at $/Mtok rates), per-session costs, daily trends, and compaction baseline token recovery. Use when analyzing spending, comparing model costs, or planning budgets.PlanningNo warnings★ 1.1K↓ —
- ap-sweep-coordinatorSpielewoy/autoprompt-skillReport the compatibility redirect to `ap-run-coordinator`; this retired role cannot perform new work.OtherNo warnings★ 1.2K↓ —
- nostr-vpnmmalmi/nostr-vpnConnect an authorized machine to a Nostr VPN private mesh, review device join requests, and verify access with the nvpn CLI. Use for account-free private networking between agent hosts, people, and servers.EngineeringNo warnings★ 1.2K↓ —
- endpoint-probehoangsonww/Claude-Code-Agent-MonitorProbes each major Agent Monitor API route — /api/stats, /api/analytics, /api/sessions, /api/pricing/cost, /api/workflows/runs, /api/cc-config/overview — and reports each one's HTTP status, latency, and response shape, flagging which are reachable. Use to verify a dashboard install is wired up correctly.DataNo warnings★ 1.1K↓ —
- ap-run-coordinatorSpielewoy/autoprompt-skillStart only ready, non-overlapping roadmap work and combine returned status at the written integration points.WritingNo warnings★ 1.2K↓ —
- image-to-uihashgraph-online/awesome-codex-pluginsRecreate an image, screenshot, or mockup as a 1:1 UI implementation. Match the reference rather than redesigning it, then render and compare the result to correct visible differences.DesignNo warnings★ 1.5K↓ —Also in 1 other repo

- minutes-debriefsilverstein/minutesPost-meeting debrief — analyzes what happened, compares outcomes to your prep intentions, tracks decision evolution. Use when the user says "debrief", "what just happened in that meeting", "what did we decide", "debrief that call", "post-meeting", "what changed", or right after stopping a recording.OtherNo warnings★ 1.6K↓ —Also in 1 other repo
