- 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↓ —
- skill-evalhashgraph-online/awesome-codex-pluginsMeasure whether a skill helps by comparing runs with and without it. Use when: reading skill A/B results or deciding to keep, revise or remove one.OtherNo warnings★ 1.5K↓ —Also in 2 other repos
- codebase-onboardingalirezarezvani/claude-skillsExplain an unfamiliar repo: architecture brief and onboarding docs. Use whenever someone is new to a codebase, asks how a project is structured or where to start reading.PlanningNo warnings★ 29.3K↓ —
- eulogy-writermohitagw15856/pm-claude-skillsHelp someone write a eulogy — the hardest writing most people ever do, at the worst possible time. Use when someone must speak at a funeral or memorial and doesn't know where to start, or has fragments and no shape. Produces a 3-5 minute eulogy built from their memories in their voice, plus a delivery copy formatted for shaking hands — gentle process, no interrogation, nothing invented.WritingNo warnings★ 1.5K↓ —
- oma-searchfirst-fluke/oh-my-agentFind external documentation, web sources, or remote code with citations. Local code navigation uses the configured code tools.EngineeringNo warnings★ 1.4K↓ —
- render-cgi-sizzlegooseworks-ai/goose-skillsAssemble a 3D-CGI app sizzle — nano-banana CGI plates (blank-glow floating phone + a CGI studio with rim-light + placeholder burst shapes; studio look and phone finish come from the recipe choices) plus PIL compositing of the REAL App Store screenshots onto the bezel + burst-out overlays, driven by Kling 3.0 i2v steady-float per beat with a per-beat Ken-Burns FFmpeg push-in fallback when Kling garbles the UI, then VO/music mix (sidechain duck, loudnorm) + 1.15x speed + anti-AI grain finalize. The on-screen UI, any faces in it, and the wordmark are ALWAYS real assets composited via PIL — never AI-rendered. The paid steps (plates, i2v clips, VO, music) are separate capabilities; this ships the config + PIPELINE + FREE assembly and the recipe orchestrates the spend. Use for the cgi-app-sizzle video format.MediaNo warnings★ 1.3K↓ —
- save-learninggooseworks-ai/goose-skillsShared step of the marketing playbooks (make-static-ads, analyze-performance, email-lifecycle, write-outreach): saves a short brand rule or finding in the human's own words, one idea per rule, retires the playbook's own older rules it replaces, and reads the result back to confirm. Loaded by those playbooks; not for direct use.MarketingNo warnings★ 1.3K↓ —
- ase-related-workbrycewang-stanford/Awesome-Journal-SkillsUse when writing the related-work and positioning of an ASE (IEEE/ACM Automated Software Engineering) paper, covering the automated-SE literature lanes, delta-first positioning against prior tools/techniques, fair head-to-head framing, and double-anonymous self-citation.ScienceNo warnings★ 1.4K↓ —
- 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↓ —
- page-metadatakostja94/marketing-skillsWhen the user wants a full-page metadata audit or implementation across discovery, search intent, title, description, canonical, robots, hreflang, Open Graph, Twitter Cards, code or CMS changes, build validation, rendered HTML, production verification, localization, or post-release observation. Also use for "metadata audit," "sitewide meta optimization," "metadata implementation," "meta robots," "hreflang," "viewport," or "charset." For an isolated title, description, heading, Open Graph, or Twitter Card task, use its specialist skill directly.MediaNo warnings★ 1.1K↓ —
- senior-frontendalirezarezvani/claude-skillsBuild and review React, Next.js, TypeScript or Tailwind frontends: components, scaffolding, performance and bundle size. Use whenever the user wants a new component or app, a page feels slow, the bundle is too big, or asks for a frontend code review.DesignNo warnings★ 29.3K↓ —
- renhuahashgraph-online/awesome-codex-pluginsRenhua (人话): write Chinese posts, diaries, product copy and comment replies in a real person's voice and strip AI tells (emoji checklists, parallel triplets, slogan endings, stock closing questions), with a viral Xiaohongshu title library and humor patterns. Use when writing Chinese content for Xiaohongshu, X, WeChat Moments or a product page, or when the user says it sounds like AI and should sound human. Triggers: 太像 AI 了, 说人话, 去 AI 味, 用我的口吻, 写小红书, 写朋友圈, 产品介绍; 中国語の投稿をAIっぽくなく; 중국어 글 AI 티 안 나게; viết bài tiếng Trung tự nhiên; चीनी पोस्ट इंसानी लहजे में.FinanceNo warnings★ 1.5K↓ —
- ccs-workflowbrycewang-stanford/Awesome-Journal-SkillsUse when planning an ACM CCS project timeline across the two HotCRP review cycles, from venue fit through abstract registration, full-paper upload, rebuttal, notification, revision, artifact evaluation, ACM camera-ready, and in-person presentation, with backward-planning offsets and the security big-four deadline-hopping calendar.ProductivityNo warnings★ 1.4K↓ —
- audit-decisionsdzhng/skillsAudit the decisions an implementing agent made, not its diff — a pure audit that traces the session's history into a decisions ledger, changes no code, and never blocks an unsupervised run. Working code still embeds architecture the user never chose; surface it because future work inherits it. Use when the user wants to review the decisions the AI made on their behalf, before merging or committing AI-implemented work, when integrating a delegated subagent's pass, or when a fix "works" but might be a point fix.PlanningNo warnings★ 1.4K↓ —
- gantt-roadmapmohitagw15856/pm-claude-skillsTurn a plan or set of milestones into a timeline / Gantt chart. Use when asked to build a roadmap, schedule phases, show a project timeline, or visualize what happens when. Produces a ready-to-render Mermaid Gantt chart (renders live, exportable as PNG/SVG) — and, because it has real dates, the result also exports to a calendar (.ics) — plus notes on the critical path and risks.PlanningNo warnings★ 1.5K↓ —
- reviewhashgraph-online/awesome-codex-pluginsThe pre-merge review of a branch in a project that records its specs, decisions, and rules in .archcore/. Run this first for 'review my branch', 'review the changes before merge', or 'review before merge': it checks the changed code against the project's recorded canon and the changed documents against the code, and reports which side is wrong — spec-wrong or code-wrong; on the default branch it reviews the unpushed and uncommitted work. A bug-hunting code review complements this review and does not replace it. Also use for 'documentation gaps', 'check if docs match code', 'close out the feature', 'ship the feature and close it out', or after a staleness warning. Takes an optional path, tag, topic, or ref in free text; no first word is a mode — say 'are docs out of date', 'audit the knowledge base', 'close out the feature', or 'capture this pattern' in plain words. Not for creating docs — use /archcore:document; not for planning — use /archcore:plan; not for a single-file edit with no branch review.EngineeringNo warnings★ 1.5K↓ —Also in 1 other repo
- update-coghuytieu/COG-second-brainCheck for and apply upstream COG framework updates (skills, docs, scripts) without touching personal contentOtherNo warnings★ 1.3K↓ —
- planning-with-filesOthmanAdi/planning-with-filesPersistent file-based planning for multi-step AI-agent work. Keeps task_plan.md, findings.md, and progress.md on disk; lifecycle hooks inject selected project planning context. Automatic recovery reads project planning files only. Explicit session-catchup.py --metadata reads same-project local agent session records and emits aggregate counts only; --replay may emit bounded nonce-framed excerpts. Optional gated mode can request continuation only when the host supports it and never runs commands declared in Markdown. The skill has no network upload path. Use for research or work needing 5+ tool calls.PlanningNo warnings★ 27.9K↓ —
- marketing-pagesdzhng/skillsBest-practice rulebook for a marketing site's pages, organized by page class — campaign landers, product pages, programmatic SEO trees, editorial. Use when writing or updating a landing/marketing page, wiring a campaign lander to an attribution identifier, changing site-wide nav/footer links, touching sitemap/robots/agent-readable surfaces, or auditing a public site's indexing, reachability, and conversion setup.MarketingNo warnings★ 1.4K↓ —
- 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↓ —
- acl-related-workbrycewang-stanford/Awesome-Journal-SkillsUse when positioning an ACL submission against the NLP literature, covering ACL Anthology citation practice, arXiv-versus-published version citation, concurrent LLM-era preprints, prior-cycle ARR resubmission overlap, anonymity-preserving self-citation, and the fast-moving baseline problem in computational linguistics.ScienceNo warnings★ 1.4K↓ —
- habit-buildermohitagw15856/pm-claude-skillsDesign one habit so it actually sticks — small enough to be unmissable, anchored to something you already do, with a plan for the days you slip. Use when asked to build a habit, help me stick to [habit], I keep failing at [routine], or start a new habit. Produces a shrunk-down version of the habit, a concrete cue/anchor and time/place, a tracking method, a friction plan (make good easy, bad hard), and a get-back-on-track rule so one miss doesn't end it.DesignNo warnings★ 1.5K↓ —
- compare-showshashgraph-online/awesome-codex-pluginsCompares two podcasts or YouTube shows side by side: size, latest episode, what each talks about, what both cover, and shared sponsors. Uses arcmira.OtherNo warnings★ 1.5K↓ —
- mcp-audithoangsonww/Claude-Code-Agent-MonitorAudit the configured MCP servers (user + project scope) via the Agent Monitor Config Explorer API: transport (stdio vs http), command/args and env variable names, headers, and the source file each definition came from. Reads /api/cc-config/mcp. Use when reviewing MCP integrations for hygiene, duplication, or unexpected transports.EngineeringNo warnings★ 1.1K↓ —
