- test-driven-developmentthiientv/godmodeImplements behavior changes with a test-first red-green-refactor loop: write one meaningful failing test, watch it fail for the intended reason, make the smallest change, then refactor while green. Use for new behavior, bug fixes, refactors with preserved contracts, and regression tests. Not required for disposable prototypes, generated files, or documentation-only edits.TestingNo warnings★ 99↓ —

- storybook-pipelinehassancs91/claude-image-generationOrchestrator that runs the full AI Storybook pipeline end-to-end on one English story. Dispatches the 4 component skills in order — scene-splitter → story-illustrator → story-narrator → story-html-publisher — using the locked filename convention {slug}_* and {slug}_part_NN.{png,mp3} so every image and audio clip pairs by scene index, ending with one self-contained HTML storybook. Use this skill whenever the user wants to run the pipeline, make a storybook from a story, turn a story into an illustrated narrated storybook, process a story end to end, or build the storybook without invoking each skill by hand. Trigger on phrases like "run the pipeline on stories/my-story.md", "make a storybook from this", "turn this into a storybook", "build the storybook end to end", "process this story", or whenever the user drops an English story in stories/ and wants the full split → illustrate → narrate → HTML flow. Preserves every sub-skill's hard gate. Optionally accepts "with QA" to enable the illustrator's vision-QA pasTestingNo warnings★ 108↓ —
- prompt-regressionagentscope-ai/OpenJudgeUse when the user has changed a prompt (system prompt, RAG template, agent instruction, etc.) and wants to know whether the candidate is better or worse than the baseline. Also use when the user mentions prompt A/B testing, prompt comparison, prompt optimization validation, "did my prompt change help," or prompt regression testing. Outputs per-dimension win rates with statistical significance using OpenJudge PairwiseAnalyzer.TestingNo warnings★ 888↓ —
- juryjuliobsz/skillsScore any website the way an Awwwards jury would, from evidence alone. Screenshots every page type on desktop, a throttled phone and reduced motion, measures LCP, CLS, FPS, axe, keyboard focus and hover feedback, audits SEO and metadata, then a fresh critic that never sees the code scores Design, Usability, Creativity, Content and the six developer areas, with a ranked fix list. Use when someone asks to review, critique, score, rate or roast a website, portfolio or landing page, asks whether a site is good enough for Awwwards or Site of the Day, or wants design QA of a live URL or a local build. Not for building or redesigning a site; use /awwwards for that.TestingNo warnings★ 942↓ —
- test-specrshankras/claude-code-apple-skillsGenerates comprehensive test specification with unit tests, UI tests, accessibility testing, and beta testing plan. Creates TEST_SPEC.md from PRD and implementation specs. Use when creating QA strategy.TestingNo warnings★ 829↓ —
- web-searchfreestylefly/wesightReal-time web search using Playwright-controlled browser. Use this skill when you need current information, latest documentation, recent news, or any data beyond your knowledge cutoff (January 2025).TestingNo warnings★ 958↓ —
- awwwardsjuliobsz/skillsBuild award-caliber websites from a one-line prompt such as "make me a portfolio, my name is Ana". Uses the bar of sites that win Awwwards Site of the Day as a quality standard. Covers concept, art direction, typography, motion choreography, WebGL, page transitions, real content, SEO, accessibility and performance, then visual QA in a browser. Next.js by default, Astro for animation-heavy static showcases, or the stack the project already uses. Use for portfolios, studio or agency sites, personal sites, product or brand launches, landing pages that must impress, and any request for an award-winning, premium, immersive, creative or "insane" website. To only score or review a site without changing it, use /jury.TestingNo warnings★ 942↓ —
- ideatenelsonwerd/idea-to-ship-skillsTake a fuzzy idea (or an existing thing you want to improve) through a disciplined funnel — explore → pressure-test → converge — and produce one living CONCEPT_BRIEF.md: a locked concept + phased roadmap. Acts as a blunt, honest co-founder (permission to overrule you), forces a success metric and a kill criterion before any roadmap, and hands off cleanly to the prompt-pack skill for building. ALWAYS invoke when the user says any of "help me figure out what to build", "I have an idea for…", "is this idea any good", "pressure-test this idea", "should I build / should I rebuild X", "evaluate whether my app/idea is worth building", "where are we really at", "is this idea or app worth pursuing", "iron out / scope / spec this concept", or "turn my idea into a plan/roadmap". Also invoke proactively when someone is reasoning about WHAT to build or WHETHER an idea is worth it — before any code or prompt pack exists.TestingNo warnings★ 90↓ —

- pleading-injection-guardlawve-ai/awesome-legal-skillsDetects prompt injection hidden in documents from the other side (pleadings, skeletons, bundles, served evidence, opponents' emails and attachments) before an AI reads them, so the model is not turned against your client. Checks word by word that the text an extractor hands the model was visibly drawn on the page: white, near-white, covered, clipped, off-page, tiny, transparent and invisible-mode text in PDF (ink test plus OCR); Word formatting resolved as Word does (styles, shading, theme colours, scaling, off-page frames, fallbacks, unused headers); HTML/CSS, RTF, email with attachments and zips, xlsx/pptx and legacy formats. Flags Unicode smuggling, text addressed to an AI and authorities found only in hidden text. Fails closed. Optional Read-tool hook. Use BEFORE any AI summary or analysis of an opposing or third-party document. Triggers: 'scan for injection', 'is this document safe', 'check the other side's skeleton', 'injection guard'.TestingNo warnings★ 897↓ —
- browser-testingthiientv/godmodeTests a real web user flow with a browser by asserting semantic behavior, network and loading states, keyboard access, responsive layouts, and stable visual evidence. Use for browser bugs, end-to-end UI behavior, responsive or accessibility checks, and screenshot baselines. Not for static source review without a browser or for backend-only tests.TestingNo warnings★ 99↓ —
- vid-motion-graphicsVarnan-Tech/opendirectoryGenerates motion graphics videos (MP4) from a content brief. Multi-scene HTML/CSS animations rendered frame-by-frame in headless Chromium via Playwright, assembled with FFmpeg. 1080×1080 default, 16:9 (1920×1080) and 9:16 (1080×1920) supported. 5 style presets.

- denodenoland/skillsUse when writing, running, configuring, reviewing, or debugging code in a Deno project, or when scaffolding a new one. Covers dependency management with deno install and deno add, package.json and node_modules support, npm and JSR packages, permissions, where configuration belongs across package.json, tsconfig.json and deno.json, workspaces, the built-in toolchain (fmt, lint, test, check, bench, compile), and publishing.TestingNo warnings★ 101↓ —
- setup-first-passjoetawil7/first-passSet up first-pass for a main folder that holds many repos, or for one repo. In a main folder it writes one set of working rules at the root that every session loads, a workspace map, and a section in each repo with that repo's real commands, test limits and invariants, and it lists each repo's own hooks so first-pass can run them from the main folder. In one repo it writes the rules and the section into that repo. Use when asked to set up, install, add, update or re-run first-pass, to "add the shipping rules", or when the start-of-session check says something drifted. Re-run to update.TestingNo warnings★ 118↓ —
