- agent-test-generatortravisjneuman/.claudeSpecialist subagent: Generates comprehensive test suites using TDD patterns. Use only when the user explicitly asks for tests, improved coverage, or test-first development.TestingNo warnings★ 106↓ —
- statistics-verifiertravisjneuman/.claudeVerify statistics from raw data with methodology checking, significance testing, claim validation, and bias detection. Use when fact-checking statistical claims, validating research findings, or auditing data analysis.TestingNo warnings★ 106↓ —

- test-strategyavelikiy/great_ctoCoverage-design method for qa-engineer — pyramid ratios per archetype, equivalence/boundary/property case selection, mutation score as the real coverage signal, and a flake-quarantine policy. Turns "coverage is 90%" (a number with no method) into a defensible test plan. Emits TEST-STRATEGY-{slug}.md, which the QA gate checks exists.TestingNo warnings★ 105↓ —
- stack-baselineavelikiy/great_ctoThe pinned default technology stack for SMB Product-Builder products. One source of truth so the architect, app-scaffolder, auth-engineer, and senior-dev never re-decide the stack per build — they build ON it. Covers framework, ORM/DB, auth, UI, payments/email/SMS, files, jobs, testing, hosting, and observability, with the chosen default + the one sanctioned alternative for each. Applied whenever a new product is scaffolded or a stack choice would otherwise be improvised. Re-deciding the stack every build is the biggest silent time sink; this kills it.TestingNo warnings★ 105↓ —
- quant-validationavelikiy/great_ctoThe methods a financial-ML result has to survive before it is evidence — purged cross-validation with an embargo, triple-barrier labelling, sample uniqueness under overlapping labels, fractional differentiation, meta-labelling, and multiple-testing correction. Written because the invariants were required of quant-researcher and nothing in the project explained how to satisfy them: a rule without a method produces either an invention or a block. Applied whenever a backtest, a feature or a label is being designed or judged.TestingNo warnings★ 105↓ —
- audit-a11yJoviDeCroock/prachtPer-route axe-core audit of a pracht app in a headless browser: alt text, contrast, landmarks, focus order, and form labels, grouped by severity and route. Use for "audit a11y", "check accessibility", "axe my app", "WCAG compliance", "screen reader test".TestingNo warnings★ 103↓ —
- scaffold-e2eJoviDeCroock/prachtSet up Playwright for a pracht app: install it, generate a `playwright.config.ts` that boots `pracht dev` (or the build via `pracht preview`), and emit a smoke test per manifest route asserting 200, head/title, no console errors, and navigation. Use for "scaffold E2E", "set up Playwright", "add browser tests", "create smoke tests for my routes".TestingNo warnings★ 103↓ —
- scaffold-testsJoviDeCroock/prachtSet up Vitest for pracht routes, loaders, and middleware — browser mode with `vitest-browser-preact` or JSDOM with `@testing-library/preact` — wiring `vitest.config.ts`, `LoaderArgs` via `@pracht/test`, and runnable test files. Use for "scaffold tests", "set up Vitest", "add unit tests", "test this loader", "test this route".TestingNo warnings★ 103↓ —
- upgrade-prachtJoviDeCroock/prachtUpgrade the `@pracht/*` packages safely: inventory installed versions, read the changelogs between installed and target, map breaking changes to real usage, apply, then walk the verification ladder (doctor, typegen, verify, build, tests). Use for "upgrade pracht", "update @pracht packages", "bump the framework", "what changed in the new pracht version", "is this upgrade safe".TestingNo warnings★ 103↓ —
- pracht-test-apiJoviDeCroock/prachtGenerate Vitest request/response tests for every handler in `src/api/`: build a `Request`, call the exported method handler directly, assert on the returned `Response` — no server boot. Use for "test my API routes", "scaffold API tests", "generate tests for src/api", "add tests for this endpoint".TestingNo warnings★ 103↓ —
- vitestPaulRBerg/agent-skillsUse for Vitest in TypeScript projects (Node, bun, React/Next.js, Effect): write, run, or debug unit/component tests, mocks, testing utilities, and coverage.TestingNo warnings★ 101↓ —
- grill-mePaulRBerg/agent-skillsInterview the user relentlessly about a plan or design until every branch of the decision tree has an explicit recorded decision and no open questions remain. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".TestingNo warnings★ 101↓ —

- cross-video-qaJimLiu/baocut用户问「我哪一期讲过 X」「这几部视频里谁说过 Y」「X 在我的视频里是怎么讲的」「有哪些讲 X 的视频」这类要在多部视频里找答案的问题时用：按意思检索、按视频去重、按当前版本重新定位，只凭找回来的原话回答，每条论断注明视频与时间，覆盖不全时说明。不用于总结或改写一部视频（那是总结、博客），也不改视频。TestingNo warnings★ 1.4K↓ —

- feature-flagsBagelHole/DevOps-Security-Agent-SkillsImplement feature flags for progressive feature rollout using LaunchDarkly, Unleash, or custom solutions.

- reuse-before-buildAi-Eastern/reuse-before-buildReuse-first decision gate for coding work. Before building, check whether the project, its platform, its installed dependencies, or a well-evidenced open-source project already provides what is needed, then decide Take, Borrow, or Build from evidence actually read. Use it whenever a task involves choosing an architecture, library, framework, or component; implementing a non-trivial feature, helper, or integration that may already exist; adding, extending, or checking tests; or resuming engineering work from a handoff, checkpoint, or compacted context, even if the user never mentions reuse. Skip it for typos, renames, and other small local edits.TestingNo warnings★ 99↓ —
- personal-boardroomFAIRY123456789/human-edge-agent-skillsStress-test a difficult career, startup, study, money, product, or life decision through a small board of explicit decision lenses, then synthesize one evidence-weighted recommendation. Use when the user is torn between options, has several identities or goals in conflict, keeps receiving contradictory advice, or wants more than a generic trade-off list.TestingNo warnings★ 98↓ —
- avenox-thumbnailavenoxai/avenoxskillsGenerate high-CTR YouTube thumbnails for a mascot-driven channel using parallel gpt-image-2 jobs via the Codex CLI.

Produces on-model mascot + a big 2-4 word hook + tool logos + high-contrast covers, saved 1280x720 ready for YouTube A/B testing.TestingNo warnings★ 97↓ —
