- slack-agent-flownanocoai/nanoclawLet an existing Slack agent create new agents that arrive as their own Slack bots — provisioned app, operator DM, and a shared three-way room, hot-started without a host restart.OtherNo warnings★ 31.1K↓ —
- brief-buildermohitagw15856/pm-claude-skillsInterview the user with sharp, one-at-a-time questions to turn a vague request into a tight, complete brief any other skill can run on. Use when a request is fuzzy, under-specified, or 'help me think this through', or before running a skill that needs inputs the user hasn't given. Produces a structured brief (goal, audience, constraints, success criteria) and hands off to the right skill — by interrogating, not guessing.PlanningNo warnings★ 1.5K↓ —
- planhashgraph-online/awesome-codex-pluginsShape a request into one end-to-end slice with observable behavior; review write scope and reversible decisions. Use when: planning, breaking down or scoping a change.PlanningNo warnings★ 1.5K↓ —Also in 2 other repos
- my-energy-mapmohitagw15856/pm-claude-skillsMap your real energy through the day and week, then match your tasks to it — hard things when you're sharp, easy things when you're not. Use when asked when should I do my hard work, map my energy, why am I so unproductive at certain times, or schedule around my focus. Produces a picture of your energy peaks, troughs, and patterns from your own observations, a task-to-energy matching plan (deep work at peaks, admin at troughs), the traps you're currently falling into, and a realistic daily shape — because fighting your natural rhythm wastes your best hours on your worst tasks.PlanningNo warnings★ 1.5K↓ —
- cn-customs-docsmohitagw15856/pm-claude-skillsUse when asked 出口报关需要什么单证, 报关资料清单, 申报要素怎么填, 报关单和发票对不上, 出口退税需要的单证, 进口清关资料, or prepare customs documents for an export or import shipment in mainland China. Produces a document checklist for this shipment (报关单 data, 商业发票, 装箱单, 合同, 委托书, licences and certificates), a cross-document consistency check, the 申报要素 to prepare for the HS code, inspection and licence flags, the timeline with the customs broker, and the records to keep for the export rebate, all marked to confirm with the broker and customs.EngineeringNo warnings★ 1.5K↓ —
- the-understudymohitagw15856/pm-claude-skillsStudy 3-5 samples of the user's real writing and decisions, build an explicit 'how you think' profile, then draft new work as their understudy — always with a 'what I couldn't infer about you' list so the gaps are visible instead of guessed. Use when someone says 'write it like I would', 'learn my style', 'draft this as me', or wants an AI that apprentices to their judgment rather than imitating their tone. Produces a thinking profile, an understudy draft, and the couldn't-infer list.WritingNo warnings★ 1.5K↓ —
- releasehyhmrright/brooks-lintCut a brooks-lint release: set the version in package.json, propagate it across all four plugin manifests and every version-bearing text file (README badges, docs site metadata), write the CHANGELOG entry, validate, then commit, push, tag, and publish the GitHub release. Triggers when the maintainer asks to "release", "cut a release", "ship a new version", or "bump and publish" brooks-lint. Do NOT trigger for: propagating an already-decided version without releasing (use `npm run bump` directly), CHANGELOG edits alone, or questions about the release process that don't ask to perform it.WritingNo warnings★ 1.6K↓ —
- inithashgraph-online/awesome-codex-pluginsInitialize KERNEL links and AgentDB in a confirmed Vaults directory.OtherNo warnings★ 1.5K↓ —
- sports-scoresmohitagw15856/pm-claude-skillsGet live scores, schedules, and standings for major leagues with zero API keys — ESPN's public JSON endpoints via curl, covering NFL, NBA, MLB, NHL, and world football. Use when asked what's the score, did my team win, today's games, or league standings right now. Produces the scores with game state (live/final/scheduled), the asked-team answer first, and the rerunnable command — with the unofficial-API caveat stated.EngineeringNo warnings★ 1.5K↓ —

- churn-analysismohitagw15856/pm-claude-skillsProduce a structured churn analysis that separates avoidable from unavoidable churn. Use when investigating why customers are leaving, identifying at-risk segments, calculating net revenue retention, or building a retention intervention plan. Produces a churn report with rate calculations, categorised reasons by avoidability, segment breakdown, timing analysis, early warning signals, and prioritised interventions ranked by estimated impact.FinanceNo warnings★ 1.5K↓ —

- os-done-or-notkharmanskyi/open-stepsALWAYS invoke this skill when work wraps up or the user asks how it went - "done or not", "are we done", "what happened", "report", "what's the status of this ticket" - in any language, and when a Stop hook asks for a session report. Produces a ten-line plain- language report: a lead, a checkmark table, and a verdict - fully done, anything needed from you, new debt, safe to close. Every "yes" names its proof; unverified says "not checked". Saves the report so the next session starts from it instead of re-exploring the repo.OtherNo warnings★ 1.3K↓ —
- 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↓ —
- 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.

- rollback-planmohitagw15856/pm-claude-skillsWrite a concrete rollback plan for a risky change (deploy, migration, feature-flag flip, config rollout) so the reverse is one command away — not an improvised debate at 2am. Use when asked to write a rollback plan, back-out plan, revert plan, or 'what if we need to undo this'. Produces a rollback plan with the signals that trigger it, exact reverse commands, verification steps, data-safety notes, and a communications template.PlanningNo warnings★ 1.5K↓ —

From the author
Set up or update a project in the vault: the four-stage folder pipeline, a project-scoped CLAUDE.md with one goal, and links to the concept pages it depends on. Use this skill when the user starts something new they will work on over time, says "create a project", "set up a folder for X", or asks to define the goal and structure of ongoing work. Do NOT use for one-off tasks, for wiki pages about a topic, or for scoping an existing project down to work in it.
