- product-analyticsalirezarezvani/claude-skillsUse when defining product KPIs, building metric dashboards, running cohort or retention analysis, or interpreting feature adoption trends across product stages.DataNo warnings★ 29.3K↓ —
- project-healthjezweb/claude-skillsAll-in-one project configuration and health management. Sets up new projects (settings.local.json, CLAUDE.md, .gitignore), audits existing projects (permissions, context quality, MCP coverage, leaked secrets, stale docs), tidies accumulated cruft, captures session learnings, and adds permission presets. Uses sub-agents for heavy analysis to keep main context clean. Trigger with 'project health', 'check project', 'setup project', 'kickoff', 'bootstrap', 'tidy permissions', 'clean settings', 'capture learnings', 'audit context', 'add python permissions', or 'init project'.EngineeringNo warnings★ 1.1K↓ —
- color-palettejezweb/claude-skillsGenerate complete, accessible colour palettes from a single brand hex. Produces 11-shade scale (50-950), semantic tokens, dark mode variants, Tailwind v4 CSS output, WCAG contrast checks. Use whenever the user supplies a brand hex and asks for a palette, mentions setting up a design system, wants Tailwind theme colours from a brand colour, or asks to check colour accessibility / contrast.DesignNo warnings★ 1.1K↓ —
- data-formshuytieu/COG-second-brainPick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat). Style-agnostic — use with whatever palette or design system the destination already has. Use when charting survey results, benchmark data, usage metrics, or research findings for a post, brief, deck, or report, and whenever the default bar chart feels like it's burying the point.DocumentsNo warnings★ 1.3K↓ —Also in 1 other repo
- research-competitors-rival-passgooseworks-ai/goose-skillsStep of the research-competitors playbook: the worker brief for profiling one rival at a capped depth, returning a fixed-shape profile. Run research-competitors instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- session-reporthoangsonww/Claude-Code-Agent-MonitorGenerate a comprehensive session report with per-model token usage (input, output, cache_read, cache_write including compaction baselines), cost breakdown via the pricing engine, tool invocations, agent hierarchy, compaction events, API errors, turn durations, and thinking block counts. Use when reviewing a specific session or summarizing activity over a date range.PlanningNo warnings★ 1.1K↓ —
- code-revieweralirezarezvani/claude-skillsUse for any code review: a pull request, a diff, a commit, or a pasted function, handler or file in TypeScript, JavaScript, Python, Go, Swift, Kotlin, C#/.NET, Java, C, C++, Rust, Ruby, PHP or Dart/Flutter. Applies per-language rule packs (security such as SQL injection and missing auth, async and resource handling, error handling, performance) and scripts that score a PR's risk and complexity, then gives a merge verdict with blocking and non-blocking findings. Use whenever the user asks to review, check or look over code, says 'code review', 'review this PR', 'review this diff' or 'is this safe to merge', or asks what is wrong with a snippet, even a single function.EngineeringNo warnings★ 29.3K↓ —
- medium-postskostja94/marketing-skillsWhen the user wants to write, publish, republish, or optimize posts on Medium.com (canonical tags, distribution, Medium SEO). Also use when the user mentions "Medium," "Medium article," "Medium story," "Medium publishing," "canonical Medium," or "publish on Medium." Not for general parasite SEO when Medium is not the target platform—use parasite-seo. For AI search visibility strategy, use generative-engine-optimization.MarketingNo warnings★ 1.1K↓ —
- inithashgraph-online/awesome-codex-pluginsInitialize team config for a project. Creates .agenteam/config.yaml (or legacy agenteam.yaml) and generates .codex/agents/*.toml.OtherNo warnings★ 1.5K↓ —
- add-codexnanocoai/nanoclawUse Codex (OpenAI's codex app-server) as a full agent provider — planning, tool orchestration, MCP tools, server-side history, session resume — alongside or instead of Claude. ChatGPT subscription or OpenAI API key, vault-only via the selected gateway. Per-group via `ncl groups config update --provider codex`. Distinct from using OpenAI as an MCP tool (where Claude remains the planner).PlanningNo warnings★ 31.1K↓ —
- compare-optionsnano-muse/nanoMuseCompare two to five options (products, plans, places, tools, offers) on the criteria that matter to the user, in a table the user can re-weight, with a recommendation. Use when the user asks which to pick, for a comparison, or "X vs Y".PlanningNo warnings★ 3.2K↓ —
- planning-with-files-zhtOthmanAdi/planning-with-files用於多步驟 AI 代理工作的持久化檔案規劃。將 task_plan.md、findings.md 與 progress.md 保存在磁碟上，生命週期鉤子會注入選定的專案規劃內容。自動恢復只讀取專案規劃檔案；只有明確執行 session-catchup.py --metadata 才會檢查本機同一專案的代理工作階段中繼資料，--replay 則會輸出有界且以 nonce 框定的摘錄。選用的閘門模式只會在主機支援時要求繼續，而且絕不執行 Markdown 中宣告的命令。此技能沒有網路上傳路徑。適用於研究或需要超過 5 次工具呼叫的工作。觸發詞：任務規劃、專案計畫、制定計畫、分解任務、多步驟規劃、進度追蹤、檔案規劃、幫我規劃、拆解專案PlanningNo warnings★ 27.9K↓ —
- varg-video-editingNewhashgraph-online/awesome-codex-pluginsWhich service to edit an existing video with, and how to edit it without breaking it. A routing guide for ten editing jobs: cut, trim, resize and join (FFmpeg, Rendi), talking-head cleanup (silence and filler cuts), long video to Shorts (OpusClip, or transcript + FFmpeg), captions and subtitles (ASS through FFmpeg, HyperFrames, Submagic), assembling from a timeline or template (HyperFrames, Shotstack), AI edits that restyle, swap people, relight or extend (varg Recast/Relight, Runway Aleph), dubbing and lip sync (HeyGen, ElevenLabs, Sync Labs), upscaling, slow motion and background removal (Topaz, Bria), finding moments and QA (Gemini, Twelve Labs), and handing off to Resolve, Premiere or Final Cut. Use when someone asks to edit, cut, trim, shorten, clip, reframe, caption, subtitle, translate, dub, lip-sync, upscale, restyle or clean up footage they already have, or asks which tool or API to edit video with. Not for making a video from a brief (varg-ai and the format skills).MediaNo warnings★ 1.5K↓ —
- museum-arthuytieu/COG-second-brainSource authentic, high-res PUBLIC-DOMAIN artwork from museum open-access APIs (Met, Cleveland, SMK, Rijksmuseum, NGA, Art Institute of Chicago, Getty, Smithsonian) instead of AI-generated or generic-stock imagery. The default move whenever a visual needs an aesthetic, credible image (blog heroes, decks, social cards, essay/spec figures). Verified keyless recipes + licensing rules inside.MediaNo warnings★ 1.3K↓ —Also in 1 other repo
- daily-journalhuytieu/COG-second-brainA passive daily work journal that Claude keeps FOR you so you never have to write it yourself. Append short entries after meaningful work (what was done, what you focused on, artifacts touched) to 01-daily/journal/YYYY-MM-DD.md. Run a guided reflection at night or in the morning. Use when you run /daily-journal, say "log this to my journal", "add to today's journal", "reflect on today/yesterday", or when finishing a meaningful chunk of work in any session.WritingNo warnings★ 1.3K↓ —Also in 1 other repo

- chi-submissionbrycewang-stanford/Awesome-Journal-SkillsUse when auditing an ACM CHI Papers submission for PCS readiness, covering the September full-paper deadline, the anonymized single-column template, word-count norms instead of page limits, subcommittee designation, supplementary and video upload, anonymization of external links, and CHI's desk-reject triage before upload.MediaNo warnings★ 1.4K↓ —
- eacl-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an EACL project timeline through ACL Rolling Review, covering the single viable ARR cycle with no fallback, backward planning from the one deadline, the rebuttal window, the commitment decision to EACL, notification, and camera-ready through ACL Anthology publication, plus re-routing since the next chance is another conference.ProductivityNo warnings★ 1.4K↓ —
- foia-requestmohitagw15856/pm-claude-skillsDraft a public-records request (FOIA / FOI / state open-records) that's specific enough to get records and hard to deny. Use when asked to write a FOIA request, records request, or freedom-of-information request to a government body. Produces a properly-scoped request: the records sought, date range and format, fee-waiver and expedited-processing asks where applicable, and citations to the governing statute.WritingNo warnings★ 1.5K↓ —
closed-loop
huytieu/COG-second-brain
PlanningUpdated Oct 23, 2026
From the author
Run one task through the V-model verification loop: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full lane) → CP-5 acceptance. The worker never grades its own homework; evidence rows trace back to AC-n. Opt-in: invoke with /closed-loop or by asking for the closed loop, proper verification, or an evidence trail. Ordinary work does not run this.
