- edit-appmicrosoft/power-platform-skillsUse when the user wants to iterate on an existing generated Power Apps mobile app after /create-mobile-app: update Application Insights configuration, the plan, data model, native capabilities, design, screens, generated app code, and preview without restarting the full project flow. Natural-language triggers include 'the app already exists', 'edit my app', 'change this screen', and 'add a feature to this app'.WritingNo warnings★ 1.1K↓ —

- ship-gatealirezarezvani/claude-skillsUse before deploying or going live ('am I ready to ship', 'can I deploy', 'preflight check').

- brainstormingmohitagw15856/pm-claude-skillsRun a real brainstorm — divergent generation without judgment, then convergent selection with explicit criteria — instead of listing ten obvious ideas and calling it creativity. Use when asked to brainstorm, generate ideas or options, explore a solution space, or name something. Produces a genuinely wide option set (including the weird tail), then a shortlist selected against named criteria with the rejects preserved.PlanningNo warnings★ 1.5K↓ —

- bug-diagnosismohitagw15856/pm-claude-skillsDiagnose a bug systematically instead of guessing — reproduce, isolate, form hypotheses, and test them to root cause. Use when debugging, chasing a defect, an intermittent failure, or 'why is this happening?'. Produces a structured diagnosis: a reliable repro, the narrowed-down location, ranked hypotheses with how to test each, and the root cause + fix once found.TestingNo warnings★ 1.5K↓ —
- nz-business-englishjezweb/claude-skillsNew Zealand business English writing style for professional communications — warm, inclusive, EN-NZ spelling (colour, organise, centre).

- api-test-planmohitagw15856/pm-claude-skillsPlan tests for an API endpoint or service — functional, negative, and contract. Use when asked to test an API, write API test cases, plan REST/GraphQL endpoint testing, or validate an API contract. Produces an API test plan — per-endpoint cases (status codes, schema, auth, validation, errors), boundary/negative cases, contract checks, and non-functional notes — so the API is verified beyond the happy 200.TestingNo warnings★ 1.5K↓ —
- hsb-appNVIDIA/skillsDiscover and run Holoscan Sensor Bridge example applications on a connected devkit. Filters available apps by the user's platform, HSB software version, board type, and sensors. Supports timed execution, failure analysis, code-edit suggestions, and iterative re-runs.WritingNo warnings★ 3.9K↓ —
- async-insteadmohitagw15856/pm-claude-skillsConvert a meeting into async work that actually decides — the doc-plus-deadline format that replaces the room, the comment-window rules, the decision-closure step that async usually fumbles, and the honest test for what still needs synchronous. Use when asked can this meeting be async, replace our status meeting with a doc, run this decision without a call, or async isn't working for us. Produces the conversion design, the async artifact format, the closure protocol, and the still-needs-a-room list.TestingNo warnings★ 1.5K↓ —

- wiki-summarymohitagw15856/pm-claude-skillsFetch Wikipedia's current summary of any topic with zero API keys — the REST summary endpoint via curl, for answers that need today's article rather than training-data memory. Use when asked what does Wikipedia say about X, get me the current summary of a topic, check a fact against Wikipedia, or has this article changed. Produces the live extract with the article link, disambiguation handling, and a clean separation between what Wikipedia says and what the model adds.ProductivityNo warnings★ 1.5K↓ —

- threat-modelmohitagw15856/pm-claude-skillsThreat-model a system or feature to find where it could be attacked, before you build it. Use when asked to threat-model, do a security design review, document security risks, identify attack surface, or apply STRIDE to a design. Produces a structured threat model: assets, trust boundaries and data flows, threats enumerated by category (STRIDE), risk scores, prioritized mitigations, and residual-risk sign-off. Defensive security for systems you own or are authorized to assess.SecurityNo warnings★ 1.5K↓ —
- rules-lawyermohitagw15856/pm-claude-skillsSettle a board game rules dispute like a fair judge — reconstruct the situation, rule from the rulebook text (pasted or known), separate rules-as-written from house rules, and keep the game night intact.

- ship-or-slipmohitagw15856/pm-claude-skillsTurn a release-readiness argument into one typed decision — ship, ship reduced, or slip — with a defined state, defined options, and a probability for each. Use when asked should we ship Friday, are we ready to release, do we slip the date, go/no-go for the release, or when a launch checklist is done and someone still has to call it. Produces a filled release state, the three-way decision with probabilities and confidence, the act-or-hold verdict against the thresholds, and the one fact that would flip it.OtherNo warnings★ 1.5K↓ —
