- skill-creatorCreminiAI/skillpackCreate new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.TestingNo warnings★ 1.2K↓ —

- storekitdpearson2699/swift-ios-skillsImplement, review, or improve in-app purchases and subscriptions using StoreKit 2. Use when building paywalls with SubscriptionStoreView or ProductView, processing transactions with Product and Transaction APIs, verifying entitlements, handling purchase flows (consumable, non-consumable, auto-renewable), implementing offer codes or promotional/win-back/introductory offers, managing subscription status and renewal state, setting up StoreKit testing with configuration files, or integrating Family Sharing, Ask to Buy, refund handling, and billing retry logic.TestingNo warnings★ 1.2K↓ —
- spreadsheet-qaOneWave-AI/claude-skillsAnswers business questions about the user's own spreadsheet or data export (CSV, TSV, XLSX from a CRM, Shopify, Stripe, QuickBooks, ad platforms, HR or payroll systems) correctly and auditably. Profiles every file first (grain, duplicate keys, embedded Grand Total rows, text-stored numbers, mixed currencies, UTC timestamps, Excel serial dates, hidden rows), states the metric definition used, computes every number in SQL or pandas instead of mental math, checks joins for fan-out, reconciles to a known total, and returns the query, filters, row counts, and rows behind the answer. Use this whenever the user says "analyze this spreadsheet", "how many...", "what's the total in this export", "which customers...", "pivot this", "revenue by month", "top 10", "what's our churn/MRR/AOV", or asks any question about their data, CSV, or Excel file, even a quick one. Also use when they ask to change values in a data file.TestingNo warnings★ 372↓ —
- shiphashgraph-online/awesome-codex-pluginsRun a project in phases. The first /ship asks one batch of project questions, proposes a split into phases, and on one approval saves a roadmap, a decision log, and one file per phase under .claude/ship/, then starts the first phase. Each phase runs end to end -- its questions, research, a spec and a plan written without approval prompts, the build through /work --auto, build, test, and smoke checks, /quiver:review, an automatic fix of the findings the review confirmed, and a plain-language report -- and a finished phase starts the next ready one in the same run. The run ends at a stopped phase or when you choose a fresh session. Every stage is saved in the phase file, so /clear then /ship continues where a run stopped. Nothing is pushed and no pull request is opened.TestingReview first★ 1.4K↓ —
- workhashgraph-online/awesome-codex-pluginsExecute a work plan or specification systematically -- read the plan, set up a branch, implement tasks with continuous testing, commit incrementally, and ship a PR. Use when you have a plan file, spec, or task list ready to execute. --auto answers the routine gates (branch, final commit, PR handoff, workspace cleanup, third failed fix attempt) in advance and stops only for a blocker, a Critical finding, or a merge conflict.TestingReview first★ 1.4K↓ —
- 703-technologies-fuzzing-testingjabrena/plinthUse when you need to add or review fuzz testing for Java APIs with CATS — including contract-driven negative testing, malformed payload validation, boundary input exploration, CI integration, reproducible failures, and local execution guidance.

- test-sitemicrosoft/power-platform-skillsTests a deployed, activated Power Pages site at runtime using browser-based navigation, page crawling, and API request verification via Playwright. Use when the user wants to test, verify, or smoke-test their deployed site.TestingReview first★ 1.1K↓ —
- bi-measure-builderOneWave-AI/claude-skillsWrites, explains, debugs, and optimizes BI calculations - Power BI / Fabric DAX measures and calculated columns, Tableau calculated fields (FIXED/INCLUDE/EXCLUDE LOD expressions, table calculations), and Looker LookML measures, dimensions, and derived tables. Use it whenever the request involves DAX, CALCULATE, a Power BI measure, a Tableau calc or LOD, LookML, or a business metric such as YoY, YTD, rolling 12 months, running total, percent of total, distinct customers, ranking, new vs returning customers, closing balances, or basket analysis. Use it especially when someone says a measure "shows the wrong total", "is blank", "ignores my slicer/filter", "repeats the same value on every row", or "is slow" - those are filter context, context transition, LOD order-of-operations, or fanout bugs this skill is built to diagnose. Produces the formula, the context it evaluates in, and a hand-checkable test with expected numbers.TestingNo warnings★ 372↓ —
- super-qaEricTechPro/super-boardSuper QA canonical workflow for functional bug-bash, evidence capture, and fix-ready issue filing. Crawls routes from `docs/super-qa/queue.md` with Playwright, records screenshots/logs/HARs, files product-readable issues with clear type/priority/area labels, and continues until traversal is complete or only human-gated blockers remain. Crawling is always browser-driven, but the regression test it leaves behind is written at whichever layer the defect actually lives — unit or integration in Vitest, e2e in Playwright only when the browser is the thing that broke. Use when the user says "run super-qa", "QA review", "bug bash", "verify and fix", or invokes `/super-qa`.TestingNo warnings★ 478↓ —
- super-buildEricTechPro/super-boardBuilder lane of the super-board pipeline — takes a `Ready` GitHub Project card into its own per-issue git worktree, makes the smallest safe change test-first (TDD, `ponytail` simplest-first, official docs first for third-party APIs, upgrades and auth/billing), opens a draft PR and hands it to QA and Review through the board; it never merges — merges go through the Reviewer's merge gate. Inside `super-board run` it runs as a lane agent in the in-session wave workflow (`workflows/super-board-wave.js`, no worker cap unless `max_workers` is set); standalone headless `claude -p` dispatch is legacy opt-in. Use when the user says "Super Build", "run the build loop", "/super-build", or invokes the skill.TestingNo warnings★ 478↓ —
