Use when the user asks to build AI agents in Dart, use Genkit flows, or integrate LLMs into Dart/Flutter applications.011Developing Genkit JSgenkit-ai/skillsDevelop AI-powered applications using Genkit in Node.js/TypeScript. Use when the user asks about Genkit, AI agents, flows, or tools in JavaScript/TypeScript, or when encountering Genkit errors, validation issues, type errors, or API problems.020Developing Genkit JSfirebase/agent-skillsDevelop AI-powered applications using Genkit in Node.js/TypeScript. Use when the user asks about Genkit, AI agents, flows, or tools in JavaScript/TypeScript, or when encountering Genkit errors, validation issues, type errors, or API problems.06Diagnosemattpocock/skillsDisciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says "diagnose this" / "debug this", reports a bug, says something is broken/throwing/failing, or describes a performance regression.02Distillpbakaus/impeccableStrip designs to their essence by removing unnecessary complexity. Great design is simple, powerful, and clean. Use when the user asks to simplify, declutter, reduce noise, remove elements, or make a UI cleaner and more focused.01Edit Articlemattpocock/skillsEdit and improve articles by restructuring sections, improving clarity, and tightening prose. Use when user wants to edit, revise, or improve an article draft.02Elevenlabs Music Generationruncomfy-com/skills>01Elevenlabs Music Generationdoany-ai/skills>01Enhance Promptgoogle-labs-code/stitch-skillsTransforms vague UI ideas into polished, Stitch-optimized prompts. Enhances specificity, adds UI/UX keywords, injects design system context, and structures output for better generation results.03Env And Assets Bootstraplllllllama/rigorpilot-skillsRigor Setup skill for README-first deep learning repo reproduction. Use when the task is specifically to prepare a conservative conda-first environment, checkpoint and dataset path assumptions, cache location hints, and setup notes before any run on a README-documented repository. Do not use for repo scanning, full orchestration, paper interpretation, final run reporting, or generic environment setup that is not tied to a specific reproduction target.08Explore Codelllllllama/rigorpilot-skillsRigor Improve implementation leaf skill for auditable candidate implementation in deep learning research repositories. Use when the researcher explicitly authorizes exploratory work on an isolated branch or worktree to transplant modules, adapt a backbone, add LoRA or adapter layers, replace a head, or stitch together meaningful low-risk migration ideas with rollback-aware records in `explore_outputs/`. Do not use for end-to-end exploration orchestration on top of `current_research`, trusted baseline reproduction, conservative debugging, environment setup, verified contribution claims, or default repository analysis.05Explore Runlllllllama/rigorpilot-skillsRigor Improve / Rigor Explore run leaf skill for bounded exploratory evidence in deep learning research repositories. Use when the researcher explicitly authorizes exploratory runs such as small-subset validation, short-cycle guess-and-check, batch sweeps, idle-GPU search, or quick transfer-learning trials, with fair-comparison caveats and no-overclaim summaries in `explore_outputs/`. Do not use for end-to-end exploration orchestration on top of `current_research`, trusted baseline execution, conservative training verification, default routing, verified SOTA claims, or implicit experimentation.05Extract Design Systemarvindrk/extract-design-systemExtract design primitives from a public website and generate starter token files for your project.03Face Swapruncomfy-com/skills>01Face Swapdoany-ai/skills>01Find Skillsagentspace-so/skills>02Find The Original Imageuseosint/skills>-03Firecrawlfirecrawl/cli|03Firecrawl Agentfirecrawl/cliFirecrawl beta agent as a web-data subagent. Use when a web question needs more than one page or one search, when results must be compared or filtered, or when a follow-up should build on an earlier run. Delegates the browsing to `agent`, returns structured data or an answer, and keeps a thread for refinements. Requires a Firecrawl API key.01Firecrawl Build Interactfirecrawl/skillsIntegrate Firecrawl `/interact` into product code for dynamic pages and browser actions after scraping. Use when a feature needs clicks, form fills, pagination, authentication-aware flows, or other multi-step interactions that plain `/scrape` cannot complete.01Firecrawl Build Onboardingfirecrawl/skillsGet Firecrawl credentials and SDK setup into a project. Use when an application needs `FIRECRAWL_API_KEY`, when an agent should add Firecrawl to `.env`, when the user wants to authenticate Firecrawl for app code, or when choosing the first SDK and docs for a new Firecrawl integration. This skill includes its own browser auth flow, so it does not depend on the website onboarding skill.04Firecrawl Build Scrapefirecrawl/skillsIntegrate Firecrawl `/scrape` into product code for single-page extraction. Use when an app already has a URL and needs markdown, HTML, links, screenshots, metadata, or structured page output. Prefer this skill over broader crawl patterns when the feature is page-level.02Firecrawl Build Searchfirecrawl/skillsIntegrate Firecrawl `/search` into product code and agent workflows. Use when an app needs discovery before extraction, when the feature starts with a query instead of a URL, or when the system should search the web and optionally hydrate result content.01Firecrawl Crawlfirecrawl/cli|01Firecrawl Downloadfirecrawl/cli|01Firecrawl Interactfirecrawl/cli|01Firecrawl Mapfirecrawl/cli|01Firecrawl Monitorfirecrawl/cli|03Firecrawl Parsefirecrawl/cli|01Firecrawl Scrapefirecrawl/cli|01Firecrawl Searchfirecrawl/cli|01Flux 2 Kleindoany-ai/skills>01Flux 2 Kleinruncomfy-com/skills>01Flux Kontextdoany-ai/skills>01Flux Kontextruncomfy-com/skills>01Git Commitgithub/awesome-copilotExecute git commit with conventional commit message analysis, intelligent staging, and message generation. Use when user asks to commit changes, create a git commit, or mentions "/commit". Supports: (1) Auto-detecting type and scope from changes, (2) Generating conventional commit messages from diff, (3) Interactive commit with optional type/scope/description overrides, (4) Intelligent file staging for logical grouping01Golang Continuous Integrationsamber/cc-skills-golangGitHub Actions CI/CD pipeline configuration for Golang projects — workflow files for test, lint, SAST, coverage and vulnerability-scan jobs, Dependabot and Renovate config files, GoReleaser release pipelines, Docker build/push, repository security settings, and AI-driven PR review. Use when setting up or improving Go project CI, writing or fixing `.github/workflows/*.yml`, adding a linter or security scanner as a pipeline job, wiring automated dependency-update bots, or adding quality gates. Covers wiring tools into a pipeline, not the analysis they perform: do NOT use for choosing or interpreting security findings (→ See `samber/cc-skills-golang@golang-security` skill) or for choosing, upgrading, or auditing dependency versions (→ See `samber/cc-skills-golang@golang-dependency-management` skill).019Golang Grpcsamber/cc-skills-golangProvides gRPC usage guidelines, protobuf organization, and production-ready patterns for Golang microservices.
