Development Claude Skills
8 673 development skills from 759 authors. They write and change code. Half of them fit into 1 830 tokens or less — that is what one costs your context window when the agent loads it. 1 213 ship runnable scripts rather than instructions alone. 42 of them cannot work without an MCP server, most often rube. We also found 1 239 copies of these same skills sitting in other people's repositories — counted once here, not 1 239 times.

Mounts Git remotes with ArtifactFS as local working trees without a full clone. Use when asked to mount a remote repo, explain committed state versus dirty overlay state, or mount multiple repos under one daemon.
Use this skill for Node.js backend AI via @cloudbase/node-sdk (>=3.16.0) — cloud functions, CloudRun, Express, Koa, NestJS, serverless APIs, scheduled jobs, LLM proxies. Only SDK supporting image generation (ai.createImageModel + generateImage). Text models via ai.createModel with groups cloudbase, hunyuan-exp, or custom-*. Model IDs (deepseek-v4-flash, deepseek-v3.2, hunyuan-2.0-instruct-20251111, glm-5, kimi-k2.6) go in the model field of generateText/streamText. MUST run two-step preflight before code — see body. Keywords: backend, 云函数, 云托管, serverless, LLM proxy, agent orchestration, generateText, streamText, generateImage, createModel, hunyuan-image, Token Credits, TokenHub, Hunyuan, DeepSeek, GLM, Kimi, MiniMax. NOT for browser/Web (use ai-model-web) or Mini Program (use ai-model-wechat).
Use this skill when a browser/Web app (React, Vue, Angular, Next, Nuxt, static sites, SPAs, dashboards, AI chat UI) needs AI models via @cloudbase/js-sdk. Default routing for page/页面/Web/前端/frontend/网页/H5 AI — call directly from browser, do NOT propose a Node.js proxy. Covers generateText and streamText. Models via ai.createModel with groups cloudbase, hunyuan-exp, or custom-*. Model IDs (deepseek-v4-flash, deepseek-v3.2, hunyuan-2.0-instruct-20251111, glm-5, kimi-k2.6) go in the model field.

CloudBase Node SDK auth guide for server-side identity, user lookup, and custom login tickets. This skill should be used when Node.js code must read caller identity, inspect end users, or bridge an existing user system into CloudBase; not when configuring providers or building client login UI.
CloudBase function runtime guide for building, deploying, and debugging your own Event Functions or HTTP Functions. This skill should be used when users need application runtime code on CloudBase, not when they are merely calling CloudBase official platform APIs.
Complete guide for CloudBase cloud storage using Web SDK (@cloudbase/js-sdk) - upload, download, temporary URLs, file management, and best practices.
Build and deploy AI agents with CloudBase Agent SDK (TypeScript & Python). Implements the AG-UI protocol for streaming agent-UI communication. Use when deploying agent servers, using LangGraph/LangChain/CrewAI adapters, building custom adapters, understanding AG-UI protocol events, or building web/mini-program UI clients.

CloudBase CLI (tcb, 云开发CLI, Tencent CloudBase命令行) resource management skill. This skill should be used when users need to deploy cloud functions, manage CloudRun apps, upload files to storage, query NoSQL/MySQL databases, deploy static hosting, set access permissions, or configure CORS/domains/routing via tcb commands. Also use for CI/CD pipeline scripting, batch operations, terminal-based CloudBase management, or when the user prefers CLI over SDK/MCP.
Code review and validation for CloudBase projects. After writing code for Web / miniprogram / CloudRun / cloud-function projects, call this skill to check for known pitfalls — auth guard misuse, missing database tables, RLS misconfiguration, storage domain setup, and SDK API misuse. Supports automated lint scripts (regex-based) + LLM semantic review.
Use CloudBase document database Web SDK only for confirmed NoSQL collection work. Query, create, update, and delete document data; if the task mentions PostgreSQL / CloudBase PG / app.rdb(), route to postgresql-development instead.
CloudBase WeChat integration guide for Mini Program WeChat Pay, Official Account JSAPI Pay, Native QR-code Pay, Official Account OAuth, openid handling, payment callbacks, and CloudBase Integration Center generated functions. This skill should be used when users ask to add, debug, or extend WeChat payment or official-account flows on CloudBase.
CloudBase official HTTP API client guide. This skill should be used when backends, scripts, or non-SDK clients must call CloudBase platform APIs over raw HTTP instead of using a platform SDK or MCP management tool.

| Use when the user wants to develop, run, preview, save, deploy, or roll back a CloudBase Web app in this conversation as a Lovable/Codex-Sites-like vibe- coding session — i.e. any request that maps to "spin up a React+Vite project, see it live in the browser, iterate, save versions, deploy". Activate ONLY for browser-rendered Web projects based on the CloudBase official React React Native / Flutter / Electron, pure cloud functions / CloudRun backends, or Next.js / Nuxt / Astro / Remix / SvelteKit (those frameworks are explicitly out of scope).
Use when auditing CloudBase cloud API wrappers, MCP tools, generated action metadata, or related docs for outdated or incorrect action names, parameters, casing, request shapes, or missing contract tests, especially during periodic quality review or before preparing corrective PRs.
Perform a full codebase review, categorize findings by severity, file GitHub issues, then fix each issue in an isolated git worktree and submit PRs. Use this skill when the user asks to audit the codebase, do a comprehensive code review, find and fix security/quality/reliability issues, or run a proactive health check across the entire repository.
Use when auditing repository documentation for drift, stale statements, broken references, or README mismatches, especially across published docs under `doc/` and key entry surfaces such as `README.md` (English default), `README.zh-CN.md`, `mcp/README.md`, and `mcp/README.zh-CN.md` during periodic maintenance or before preparing corrective PRs.
Reusable git delivery workflows derived from local slash commands (commit, push, PR, release notes, and GitHub Actions failure triage with worktree-based fixes).
Triage, repair, and close MCP attribution issues from the local report API with evidence-driven decisions and isolated Worktrunk worktrees. Use this skill when Codex needs to process `tool` attribution issues and skills-related attribution issues, inspect related runs, decide whether the issue is actionable in `mcp/src` or `config/source/skills`, update attribution fields as `owner=codex`, and then complete the fix loop through GitHub issue tracking, worktree-based code changes, PR submission, and follow-up iteration when the problem is repairable.
Use when running or scheduling periodic repository review cycles that must dispatch the correct reviewer, aggregate findings, and escalate outcomes into reports, issues, or corrective PRs across API contracts, documentation freshness, code quality, and CloudBase skill quality.
> Uncovers Gradle project structure, task hierarchies, and resolved property values using core Gradle diagnostic tools; use for mapping modules, listing runnable tasks, and auditing build configuration. Do NOT use for running builds/tests or source code exploration.
> Provides a persistent, project-aware Kotlin REPL for rapid logic verification and prototyping within the project's JVM classpath; use for testing dynamic behavior, prototyping snippets, or rendering Compose UI previews. Do NOT use for exploring library APIs (prefer `searching_dependency_sources`) or running Gradle builds.
> Searches and retrieves official Gradle User Guide, DSL Reference, and internal engine source code authoritatively; use for researching core Gradle features, verifying behavior, and deep-diving into internals. Do NOT use for project dependency source exploration (use `searching_dependency_sources`) or running builds.
> Provides expert build engineer guidance on Gradle Kotlin DSL scripts, plugin development, and deep internals research; use for build failures, compilation errors, dependency conflicts, or complex build authoring. Do NOT use for executing builds/tests (use `running_gradle_builds`/`running_gradle_tests`) or dependency graph auditing.
> Guides commit message writing for the kotlinx-rpc project. Use this skill whenever committing code, writing commit messages, or when the user asks about commit conventions. "commit", "commit message", "git commit", writing changelogs from commits.
> Audits and manages Gradle dependency graphs with high-resolution update checks, transitive tree analysis, and Maven Central discovery; use for dependency auditing, finding stable updates, and resolving GAV coordinates. Do NOT use for exploring dependency source code (use `searching_dependency_sources`) or running builds.
> Update kotlinx-rpc documentation — version bumps, content edits, Writerside topics, KDoc, README, skills, and internal workflows. Use this skill whenever the user wants to bump the Kotlin version in docs, bump the library version, update the changelog, edit documentation topics, add a migration guide, update the version switcher, fix version references, write or update KDoc on public APIs, update the README, update Claude skills, or modify CLAUDE.md. Also trigger when the user mentions "update docs", "doc version", "release docs", "Writerside", "v.list", "changelog", "KDoc", "Dokka", "README", "skill", "CLAUDE.md", or wants to sync documentation with a new release.
>- Explores and searches source code of all external library dependencies, plugins, and Gradle internals via indexed symbol, full-text, and glob search; STRONGLY PREFERRED for understanding APIs, finding class/method definitions, and reading implementation logic. Do NOT use for project source code (use grep), Gradle documentation (use `researching_gradle_internals`), or Maven Central discovery (use `managing_gradle_dependencies`).
> Determine which LOCAL verification checks to run for kotlinx-rpc changes and execute them on the developer's machine. TeamCity builds and GitHub Actions workflows are out of scope -- this skill covers only what can and should be run locally before pushing. Use this skill whenever changes are made to the codebase and you need to verify correctness before committing or opening a PR. Also use it when the user asks to "run checks", "verify changes", "run verifications", "what checks do I need", "validate my changes", "pre-PR checks", or "local checks". Trigger proactively after completing any code modification task -- even if the user doesn't explicitly ask, suggest which verifications are relevant based on what changed.
> Executes and orchestrates Gradle builds with background management, surgical task output capturing, and structured failure diagnostics; ALWAYS use instead of `./gradlew` for core lifecycle tasks (build, assemble), dev servers, and troubleshooting. Do NOT use for running tests (use `running_gradle_tests`) or dependency graph auditing.
> Modify, build, publish, and verify the Kotlin/Native shim artifacts (gRPC shim and protobuf shim) in native-deps/shims/. Use this skill whenever the user wants to change shim C/C++ source code, update shim headers or .def files, bump a shim upstream version, add or remove archives from the overlap excludes list, patch KLIB metadata, update the annotation module, run shim fixture tests, publish shim artifacts locally, or debug any native shim build failure. Also trigger when the user mentions "shim", "cinterop", "native interop", "grpc shim", "protobuf shim", "KLIB patcher", "overlap archives", "native-deps", "Bazel shim build", or "shim verification".
> Verify that the kotlinx-rpc compiler plugin compiles successfully against multiple Kotlin compiler versions, and fix any incompatibilities found. Use this skill whenever the user wants to check compiler plugin compatibility across Kotlin versions, test a new Kotlin version, fix compiler plugin build failures after a Kotlin upgrade, ensure the CSM templates produce valid code for all supported versions, or test against Kotlin Master. Trigger on phrases like "verify compiler plugin", "check compatibility", "test Kotlin versions", "compiler plugin broken", "fix for Kotlin X.Y", "support new Kotlin version", or "Kotlin master".
> Bump the Earth2Studio version on main to start a new development cycle. This unblocks commits on main after a release branch has been merged. Performs a CHANGELOG update (new blank section) and a hatch version bump. Use when main already has the release merge but still carries the old version string, or when the developer-release-rebase skill detects the version was already bumped during rebase and only the changelog/version housekeeping remains.
> Prepare a new minor alpha release of Earth2Studio by rebasing the release candidate branch onto main, bumping the version, updating the changelog, updating the README latest-news highlights, stripping example version tags, and pushing for PR. Use when releasing, cutting a release, preparing a release branch, rebasing a release, or bumping the version for a new development cycle.
API design patterns and conventions for this project. Covers RESTful URL naming, response format standards, error handling, and authentication requirements. Use when writing or reviewing API endpoints, designing new APIs, or making decisions about request/response formats.
