- research-audience-segment-passgooseworks-ai/goose-skillsStep of the research-audience playbook: the worker brief for researching one buyer group, returning notes in a fixed shape. Run research-audience instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- 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↓ —
- ux-extractjezweb/claude-skillsExhaustively extract UX patterns from a reference web app. Walks every screen, captures screenshots of every state, records interaction patterns, copy verbatim, keyboard shortcuts, responsive treatments, motion, and empty/error/loading states. Produces a reusable pattern library that other audits can compare against. The inverse of ux-audit — asks 'what is the bar?' rather than 'does this match the bar?'. Trigger with 'learn from X', 'extract patterns from X', 'study X's UX', 'reverse engineer the UX of X', 'build a pattern library from X'.DesignNo warnings★ 1.1K↓ —
- asc-build-lifecyclerorkai/app-store-connect-cli-skillsTrack build processing, find latest builds, and clean up old builds with asc. Use when managing build retention or waiting on processing.OtherNo warnings★ 1.1K↓ —
- asc-signing-setuprorkai/app-store-connect-cli-skillsSet up bundle IDs, capabilities, signing certificates, provisioning profiles, and encrypted signing sync with the asc cli. Use when onboarding a new app, rotating signing assets, or sharing them across a team.EngineeringNo warnings★ 1.1K↓ —
- brainstormhashgraph-online/awesome-codex-pluginsExplore ideas, compare approaches, and produce a validated spec before planning. Use when the user describes what to build, asks how to approach something, proposes a new feature or design change, or needs to explore options before implementation.PlanningNo warnings★ 1.5K↓ —
- asc-in-app-eventsrorkai/app-store-connect-cli-skillsCreate and localize App Store in-app events, upload event media, and submit or recover event review submissions with asc. Use when managing in-app events, event card or details page assets, or event-specific submission errors.PlanningNo warnings★ 1.1K↓ —
- email-lifecycle-send-checkgooseworks-ai/goose-skillsChecks a drafted email flow or broadcast before it is loaded: flow logic and exits, overlaps, offer depth and codes, stock, claims, consent and legal footer, SMS rules, rendering, voice and AI-copy tells, and the goal metric. Returns a pass / fixed / open-question table. Use alone when you already have the finished draft and the brand's product and policy facts; otherwise run email-lifecycle.ProductivityNo warnings★ 1.3K↓ —
- health-checkhoangsonww/Claude-Code-Agent-MonitorRun comprehensive health checks on the Claude Code Agent Monitor system. Validates dashboard API, database, WebSocket, hooks, and disk usage. Use to verify the monitoring setup is working correctly.DataNo warnings★ 1.1K↓ —
- evals-bootstrapundefined-ui/second-brain-osScaffold a first eval suite for an agent: mine real failures into cases, write behavioural checks over traces, and generate the runner. Use when the user wants evals, regression tests for an agent, a golden set, or asks how to know a prompt/model change did not break things. Do NOT use for a single task's done-check (goal-test) or for auditing context (context-audit).TestingNo warnings★ 1.2K↓ —
- harness-auditundefined-ui/second-brain-osAudit an agent's harness against the four rings: containment, guides, sensors, permissions. Use when the user asks whether their agent setup is safe, wants a review of sandboxing / permissions / hooks / AGENTS.md guardrails, or asks what a bad session could break. Read-only: reports the blast radius and a hardening list, changes nothing. Do NOT use for context layout (context-audit) or cost routing (gate-check).EngineeringNo warnings★ 1.2K↓ —
- gate-checkundefined-ui/second-brain-osFind the decisions in a pipeline that do not need the expensive model and propose the gate for each: a rule, a classic classifier, or a small model, with fail-closed routing. Use when the user asks to cut model costs or latency, says the big model handles everything, or wants a triage / routing / filter layer in front of an agent. Analysis plus an optional baseline scaffold. Do NOT use for auditing context layout (context-audit) or for building eval suites (evals-bootstrap).ProductivityNo warnings★ 1.2K↓ —
- second-brain-changed-my-mindundefined-ui/second-brain-osTrace where the user's recorded position on something has shifted: superseded claims, contradictions between sources of different dates, and what evidence moved them. Use this skill when the user asks what they have changed their mind about, how their thinking on a topic developed, what they used to believe, or wants a quarterly look back at their own positions. Do NOT use for finding contradictions between sources with no time dimension, or for a current-state answer.OtherNo warnings★ 1.2K↓ —
- second-brain-backfillundefined-ui/second-brain-osImport a large archive into the vault in controlled batches: triage what is worth ingesting, process oldest first, checkpoint after every batch, and keep cost visible. Use this skill whenever the user wants to import years of bookmarks, an export from another notes app, a downloads folder, a chat history dump, or says "backfill", "bulk import", "process my archive". Do NOT use for ingesting one or a few new sources, which is second-brain-ingest.ProductivityNo warnings★ 1.2K↓ —
- second-brain-privacyundefined-ui/second-brain-osAudit the vault for material that should not be in it: credentials, other people's private information, confidential work, and anything the user would not want synced or backed up. Use this skill when the user asks about privacy, is about to share or sync the vault, has just imported chat history or meeting notes, or asks what is sensitive in their notes. Do NOT use to delete anything on your own, or as a substitute for the publishing check.ProductivityNo warnings★ 1.2K↓ —
- infra-setupevo-hq/evoNon-user-invocable provider/setup reference for evo backend switching, prerequisite checks, and auth/install guidance.OtherNo warnings★ 1.5K↓ —Also in 1 other repo
- second-brain-metricsundefined-ui/second-brain-osRecord a dated snapshot of the vault's health numbers and compare against previous snapshots so trends are visible. Use this skill for a monthly or quarterly check, when the user asks whether the vault is improving, or asks to track its numbers over time. Do NOT use for a one-off graph analysis, which is second-brain-graph, or for structural repairs.OtherNo warnings★ 1.2K↓ —
- second-brain-reviewundefined-ui/second-brain-osProduce a periodic review of a second-brain vault: what was added, which topics are growing, what contradicts what, which questions are still open, and what is worth reading next. Use this skill whenever the user asks for a weekly or monthly review, asks what changed in their vault, what they have been learning about lately, or what they should look at next, and when a scheduled review task fires. Do NOT use for structural linting, for ingesting sources, or for answering a specific factual question.EngineeringNo warnings★ 1.2K↓ —
- second-brain-renameundefined-ui/second-brain-osRename a page safely: update the file, fix every inbound wikilink, add the old name as an alias, and log it. Use this skill whenever a page needs a different canonical title, the user says "rename X to Y", asks to fix an inconsistent title, or after a lint run flags naming problems. Do NOT use for merging two pages, for moving a page between folders without a name change, or for renaming files outside the wiki.OtherNo warnings★ 1.2K↓ —
- varg-product-lockNewhashgraph-online/awesome-codex-pluginsTurns product photos into AI video shots that keep the product identical: a lock sheet (fixed geometry, fixed surface, allowed motion), a reference pack of 2-4 angles passed as @image roles to Seedance 2.5 or Kling 4, a camera-risk ladder (locked frame → push-in → slide → small orbit), banned motion words, one action per 4-6 s shot, a drift check with varg video_analyze, and the real packshot composited back where text must be exact. Fixes the #1 "looks fake" tell in AI product ads: warped logos, melted labels, products that change shape or size between shots. Use when a product drifts, morphs, changes color or loses its label in AI video, when someone asks for "consistent product", "keep my logo", "product looks different in every shot", or before a batch of product videos for TikTok Shop, Meta or Amazon. Not for people and characters staying the same (use varg-consistent-characters or varg-character-design).DocumentsNo warnings★ 1.5K↓ —
- 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↓ —
- research-market-market-passgooseworks-ai/goose-skillsStep of the research-market playbook: the worker brief for researching the market itself, including category, size, changes, pricing norms and demand. Run research-market instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- analyze-performance-diagnosegooseworks-ai/goose-skillsStep of the analyze-performance playbook: flags tracking breaks with fixes and explains each big metric move with evidence, confidence and ruled-out causes. Run analyze-performance instead; not for direct use.OtherNo warnings★ 1.3K↓ —
- email-lifecycle-broadcast-plannergooseworks-ai/goose-skillsStep of the email-lifecycle playbook: builds the month's send calendar and writes this week's email and SMS broadcasts against the approved cadence and segments. Run email-lifecycle instead; not for direct use.PlanningNo warnings★ 1.3K↓ —
