- analyzing-projectsCloudAI-X/claude-workflow-v2Analyzes codebases to understand structure, tech stack, patterns, and conventions. Use when onboarding to a new project, exploring unfamiliar code, or when asked "how does this work?" or "what's the architecture?"PlanningNo warnings★ 1.4K↓ —
- writing-guidelinesfcakyon/claude-codex-settingsThis skill should be used when the user asks to "review writing", "check documentation style", "audit interface copy", or "apply writing guidelines".WritingNo warnings★ 1.2K↓ —
- dispute-lettermohitagw15856/pm-claude-skillsWrite a letter to dispute an incorrect charge, bill, or record. Use when asked to dispute a credit-card charge, contest a bill or invoice, challenge a credit-report error, or formally dispute a fee. Produces a clear dispute letter — what's being disputed, why it's wrong, the evidence, and the correction requested — in the firm, paper-trail tone these situations need.ScienceNo warnings★ 1.5K↓ —
- code-review-webrampstackco/claude-skillsReview web application code for bugs, security issues, performance problems, and stack-specific anti-patterns. Use this skill whenever the user wants to review code, debug a production issue, investigate a build failure, audit security, or check a PR before merging. Triggers on code review, review my code, debug, build error, broken, not working, why is X failing, check this code, security check, PR review, audit code, refactor. Also triggers when investigating 4xx or 5xx errors, deploy failures, environment variable issues, and CMS integration problems.EngineeringNo warnings★ 1K↓ —
- growth-funnelkostja94/marketing-skillsWhen the user wants to plan growth using the AARRR framework, diagnose growth bottlenecks, or map actions across the customer lifecycle. Also use when the user mentions "growth funnel," "AARRR," "pirate metrics," "acquisition activation retention," "customer lifecycle metrics," or "growth framework." For retention tactics, use retention-strategy.MarketingNo warnings★ 1.1K↓ —
- python-guidelinesfcakyon/claude-codex-settingsThis skill should be used when writing, reviewing, or refactoring Python code. Covers code integration, idiomatic patterns, docstring formatting, anti-abstraction rules, and software engineering basics.EngineeringNo warnings★ 1.2K↓ —
- os-ask-simplekharmanskyi/open-stepsALWAYS invoke this skill before asking the user any technical question or offering options, and whenever they ask to be asked in plain words - "ask simple", "ask me simply", "ask me in plain words" - in any language. ALWAYS invoke it too when the user asks for your view on a technical choice: whether it is worth doing, more than the problem needs, or replaceable by something simpler, and which option you would take. Invoke it even when the code makes the answer look obvious: the checks are what make the answer more than a guess. Rewrites the question in plain words and always ends with one marked recommendation. A structural choice first passes six checks, shown as a table: effort now, simpler substitute, extra work later, lock-in, over-engineering, easy to undo. Doing nothing is always weighed.EngineeringNo warnings★ 1.3K↓ —
- openai-frontend-designfcakyon/claude-codex-settingsUse for new frontend applications, dashboards, games, creative websites, hero sections, and visually driven UI from scratch, or when the user explicitly asks for a redesign/restyle/modernization. Builds from clean, airy, high-taste, readable image-generated concept design with section-specific references, faithful implementation, and browser testing.DesignNo warnings★ 1.2K↓ —
- academic-cvmohitagw15856/pm-claude-skillsBuild or tailor an academic CV for faculty, postdoc, research or fellowship applications: publications, grants, teaching, supervision and service in the order the field expects, with consistent citations. Use when asked to write my academic CV, update my CV for a lectureship, tenure-track or postdoc application, format my publications list, or adapt my academic CV for an industry research role. Produces the full academic CV, a field-appropriate section order, a clean publications list in one citation style, and a two-page summary version when asked.ScienceNo warnings★ 1.5K↓ —
- asc-testflight-orchestrationrorkai/app-store-connect-cli-skillsOrchestrate TestFlight distribution, groups, testers, and What to Test notes using asc. Use when rolling out betas.TestingNo warnings★ 1.1K↓ —
- 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↓ —
- all-hands-deckmohitagw15856/pm-claude-skillsBuild an all-hands that lands with everyone from intern to VP — the mixed-altitude structure (the story for all, the numbers for some), the wins-with-names section done right, the hard-news slide handled straight, and the Q&A design that gets real questions. Use when asked build the all-hands deck, make the monthly town hall not boring, how do we share the numbers with everyone, or announce this change at all-hands. Produces the segment structure, the altitude-mixed content rules, the hard-news handling, and the Q&A mechanics.DocumentsNo warnings★ 1.5K↓ —
- 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↓ —
- goose-videogooseworks-ai/goose-skillsMake a video ad in this chat from a real reference ad, found or theirs; styles are the fallback. Follow every answer's next_step.MediaNo warnings★ 1.3K↓ —
- 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↓ —
- ai-code-reviewmohitagw15856/pm-claude-skillsReview AI-authored code for its characteristic failure modes — plausible-but-wrong logic, hallucinated APIs, over-engineering, dead scaffolding, and silent security shortcuts. Use when reviewing an AI-generated or heavily AI-assisted PR, when AI-written code keeps shipping subtle bugs, or when setting review standards for a team using coding agents. Produces a focused review with AI-specific findings, verification steps per risk class, and a team checklist for AI-authored changes. For general PR review use code-review-checklist — this skill covers what that one assumes a human wouldn't do.EngineeringNo warnings★ 1.5K↓ —
- expense-filermohitagw15856/pm-claude-skillsTurn a pile of receipts into a filed expense report through a tool-using agent — extraction, policy checks, and categorization done for you; submission gated on your approval. Use when asked to file my expenses, process these receipts, build my expense report, or expense this trip. Produces the itemized report with policy flags and an approval-gated filing plan.PlanningNo warnings★ 1.5K↓ —
- backup-strategymohitagw15856/pm-claude-skillsSet up a backup system that actually protects your photos, files, and devices — built on the 3-2-1 rule and, crucially, tested so it works when you need it. Use when asked how to back up my data, set up backups, protect my photos/files, or what's a good backup strategy. Produces a 3-2-1 plan tailored to your devices and data, specific what-to-back-up priorities, an automation setup so it happens without you, a restore-test step, and protection against the failure that ruins backups (ransomware/sync-deletes reaching the backup).TestingNo warnings★ 1.5K↓ —
- integrations-page-generatorkostja94/marketing-skillsDeprecated compatibility entry for Integration Page construction. This page is now maintained in Pagina; install and use page-builder to build a new Integration Page.OtherNo warnings★ 1.1K↓ —
- edbt-experimentsbrycewang-stanford/Awesome-Journal-SkillsUse when designing or auditing EDBT empirical evaluations for database-systems work, covering real workloads and datasets, fair and tuned baselines, honest measurement across realistic scales, reproducible harnesses, and the higher bar of the Experiments & Analysis paper where the measurement itself is the contribution.DataNo warnings★ 1.4K↓ —
- git-worktree-manageralirezarezvani/claude-skillsUse when running several branches or agents in parallel on one repo. Creates worktrees with isolated ports and env via worktree_manager.py and removes stale ones with worktree_cleanup.py.EngineeringNo warnings★ 29.2K↓ —
- claude-apihashgraph-online/awesome-codex-pluginsAnthropic Claude API patterns for Python and TypeScript. Covers Messages API, streaming, tool use, vision, extended thinking, batches, prompt caching, and Claude Agent SDK. Use when building applications with the Claude API or Anthropic SDKs.EngineeringNo warnings★ 1.5K↓ —
- 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↓ —
- doca-devemuNVIDIA/skillsUse this skill when the user is doing hands-on DOCA Device Emulation on a BlueField DPU — exposing a custom emulated PCIe device the host sees as a real peripheral while DPU-side code runs the backend, picking the sub-library (PCI Generic, virtio-net, virtio-fs), wiring the per-sub-library Core context plus doorbell / DMA primitives, querying `doca_devemu_*_cap_*`, or debugging DOCA_ERROR_* from a `doca_devemu_*` call. Trigger even when the user does not say "devemu" — typical implicit phrasings include "expose a custom PCIe device from BlueField to the host", "host should see a virtio NIC backed by my DPU code", "lspci does not show my emulated device", "device enumerated but no driver binds", "DPU sees nothing when host kicks the queue", or "virtio feature negotiation failed at bind". Refuse and route elsewhere for the packaged DOCA SNAP / Virtio-net Services, host-side virtio kernel drivers, backend body design, or standard BlueField NIC behavior — those belong to other skills.DesignNo warnings★ 3.8K↓ —

WritingUpdated Oct 23, 2026
From the author
A 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.
