- react-uihashgraph-online/awesome-codex-pluginsUse when building any val with a user interface — dashboards, web apps, landing pages, forms, admin tools, anything users see in a browser. Covers JSX/React conventions, Twind/Tailwind styling, React version pinning, the view-source link requirement, and what to avoid (template-string HTML, external assets).DesignNo warnings★ 1.5K↓ —
- repairhashgraph-online/awesome-codex-pluginsSafe maintenance for an existing docflow setup. Regenerates INDEX.md, installs or refreshes recognized DocFlow-managed helper scripts, runs link checks, and reports placeholder/validation issues. Use when docflow exists, after adding or renaming docs, or when doctor recommends repair.OtherNo warnings★ 1.5K↓ —
- gentle-ai-issue-creationGentleman-Programming/gentle-shellCreate and triage GitHub issues from repository evidence. Trigger: issue creation, bug reports, feature requests, or issue approval.OtherNo warnings★ 1.6K↓ —
- 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★ 1.3K↓ —
- 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★ 1.3K↓ —
- 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★ 1.3K↓ —
- 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↓ —
- ui-demohashgraph-online/awesome-codex-pluginsRecord polished UI demo videos using Playwright.

- cell-databrycewang-stanford/Awesome-Journal-SkillsUse to build Cell's data and code deposition plan and the Data and Code Availability statement that lives inside STAR Methods Resource Availability — approved repositories, accessions/DOIs at submission, and Cell's three-bullet availability format with Mendeley Data as Elsevier's default.PlanningNo warnings★ 1.4K↓ —
- os-say-simplekharmanskyi/open-stepsALWAYS invoke this skill when the user asks for simpler or shorter about something said or written - "say it simply", "what does this mean", "I don't understand your answer", "too long", "wait, what?", "bro" - in any language, about any text: your own answer, a report, a review comment, an error. "I don't understand what to DO" is os-step-by-step; this skill restates text. It restates for a reader who does not read code: leads with the point, keeps every number, warning and caveat - no facts added, no bad news dropped. A number returns exactly that many points, most important first.WritingNo warnings★ 1.3K↓ —
- handbook-pagemohitagw15856/pm-claude-skillsWrite the handbook page that ends the repeated explanation — the answer-shaped structure (task-first, context second), the ownership and freshness header, and the write-once-point-forever discipline that turns tribal knowledge into infrastructure. Use when asked document how we do X, write the wiki page for this process, I explain this every month, or make this knowledge survive me. Produces the page with task-first structure, the header block, the worked example, and the pointer habit.DevOpsNo warnings★ 1.5K↓ —
- 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↓ —
- 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↓ —
- miglioradagoSte/squadraImprove a project's development workflow from observed failures, repeated work and avoidable waits. Apply scoped, verified remedies and useful project instructions, then automatically commit owned changes when the project's required checks and reviews are complete. Use after recurring development friction or when asked to improve the process; do not add rules without evidence.EngineeringNo warnings★ 1.3K↓ —
- partshashgraph-online/awesome-codex-pluginsStudios build on each other with parts from games, apps, music and video that their owners choose to share or sell (a creature, a level generator, a chase camera, a bot brain, a pickup mechanic, an audio pack). Use this when planning or making games, apps, music or video (look for pieces before writing one from scratch), when the person asks what parts exist, says "use the X from that game", "make this reusable" or "share this", and before a game that uses parts goes online.MediaNo warnings★ 1.5K↓ —
- sci-databrycewang-stanford/Awesome-Journal-SkillsUse to build Science's data, code, and materials availability — mandatory deposition in approved repositories, accession numbers, a compliant data-availability statement, and materials/reagent sharing.ScienceNo warnings★ 1.4K↓ —
- wedding-speechmohitagw15856/pm-claude-skillsA best-man/maid-of-honour/parent wedding toast that actually lands — funny without roasting, moving without syrup, short enough that nobody checks their phone. Use when someone has to give a wedding speech and has either nothing or a dangerous first draft. Produces a 2-4 minute toast built on one good story, plus delivery notes and the three jokes to cut.ProductivityNo warnings★ 1.5K↓ —
- warranty-claimmohitagw15856/pm-claude-skillsGet a broken product repaired, replaced, or refunded under warranty — with the claim message written, the proof to attach, and the consumer-law backstop for when 'out of warranty' isn't the whole story. Use when asked to make a warranty claim, my [product] broke and it's still under warranty, the manufacturer won't honor the warranty, or how do I get this fixed for free. Produces a ready-to-send claim message, the exact evidence to include, the repair-vs-replace-vs-refund position, and an escalation ladder for when the first answer is no.LegalNo warnings★ 1.5K↓ —
- agent-severancemohitagw15856/pm-claude-skillsOffboard an AI agent the way you'd offboard an employee — inventory what it knew and touched, export then purge its memory, revoke every credential and access grant, and write the handover for its successor (human or agent). Use when decommissioning an agent or bot, switching agent vendors, ending an AI pilot, or when someone asks 'what did this thing have access to?'. Produces a severance checklist, an access-revocation table, a memory disposition record, and a successor handover.WritingNo warnings★ 1.5K↓ —
- year-in-reviewmohitagw15856/pm-claude-skillsRun an honest personal year-in-review and set next year's direction — wins, misses, an energy audit, and one theme, not a resolution list that dies in February. Use when asked for a personal year in review, a yearly reflection, to reflect on the past year, or plan next year. Produces the structured retrospective (what worked, what didn't, what you learned), an energy audit of what gave vs. drained you, the honest misses, and a single theme with a few concrete commitments. Personal, not corporate.EngineeringNo 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↓ —
- oma-bootstrapfirst-fluke/oh-my-agentInstall or verify the oma CLI and its runtimes (bun, uv, serena) before any oma-* skill, agent, or workflow runs an `oma` command. Use when `oma` is missing from PATH, when a skill says to run `oma ...` and the shell reports "command not found", or on the first task in a fresh Cursor or Grok Bot workspace.EngineeringNo warnings★ 1.4K↓ —
- rekallhashgraph-online/awesome-codex-pluginsCompact the current Codex VS Code extension thread through Rekall with a verified handoff and optional one-time continuation. Use on an explicit compaction request or after a substantial completed stage; standalone Codex CLI sessions are unsupported.EngineeringNo warnings★ 1.5K↓ —
