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.

Official GitHub Model Context Protocol Server for repository management.
Use the Studio CLI to manage local WordPress sites, authentication, and preview sites. Invoke this skill when you need to run Studio CLI commands, manage sites, or troubleshoot site issues.
> Analyzes a codebase's modularity imbalances using the Balanced Coupling model and produces a review of design issues. Use when reviewing existing code for coupling problems, assessing architecture quality, identifying distributed monolith risks, or finding areas where changes are unexpectedly expensive.
> evaluating coupling between components, reviewing code modularity, deciding whether to split or merge modules/services, assessing integration patterns, classifying coupling as balanced or unbalanced, applying DDD strategic and tactical patterns, reasoning about cohesion vs coupling trade-offs, identifying distributed monolith risks, or explaining why a system is hard to change. Provides the three-dimensional framework (integration strength, distance, volatility) and the balance rule for making coupling decisions.

| Internal template for creating or refactoring a skill into the repository's reference-first shape.
| Generate a Beamer slide deck from the final tutorial and approved module structure.
| Scaffold a LaTeX project (`latex/main.tex`, optional bibliography wiring, structure) from an existing Markdown draft.
>- Read, search and triage the user's Papr RSS subscriptions from the shell via the `papr` CLI. Use when the user wants to catch up on their feeds, find or summarize articles they've subscribed to, check what's unread, star/save my feeds", "any unread RSS", "summarize this feed", "search my subscriptions for X", "mark these read", "subscribe to <url>", "refresh my feeds".
| Deprecates a CDS component, hook, or other exported symbol with consistent JSDoc, version tags, and docsite metadata across every public export path (web, mobile, common, visualization), not only the original package. Use whenever the user asks to deprecate a CDS component or API, mark something as deprecated, add @deprecated / @deprecationExpectedRemoval, or update deprecation warnings in apps/docs metadata under components or hooks (webMetadata.json / mobileMetadata.json / metadata.json). Also use when replacing a component or hook and sunsetting the old one. Always finish by running
Guidelines writing styles API (styles, classNames, and static classNames) for a CDS component. Use this skill when adding customization options to a React component via `styles` or `classNames` props or when needing to update the docsite with component styles documentation.
Resolve rebase/merge conflicts in CDS release-versioning files — package.json "version" fields and CHANGELOG.md entries — that arise because packages were versioned independently on master and the current branch. Recomputes each package's version by applying the branch's bump type (patch/minor/major) on top of master's latest version, rewrites CHANGELOG entries with today's date and the new version, then continues the rebase and formats. Use when the user asks to "resolve a versioning conflict", "resolve a package.json conflict", "resolve a changelog conflict", or when you organically detect conflict markers in package.json / CHANGELOG.md files during a rebase or merge. When detected organically, ALWAYS ask the user for confirmation before running this flow.
Use this skill whenever working on CDS React components in any package.
USE THIS when asked to work on a new or existing (MOBILE) CDS React component in packages/mobile
USE THIS when asked to work on a new or existing (WEB) CDS React component in packages/web
Back-port a specific commit from master to a release branch via cherry-pick. Creates a dedicated backport branch, attempts the cherry-pick, pushes it, and opens a PR by default. Returns to the original branch when done (success or failure). If there are merge conflicts, diagnoses the root cause without attempting an autonomous resolution. Use when asked to "backport", "cherry-pick to release", or "port a fix to a release branch".
Analyzes the previous N commits for breaking changes across the CDS public API surface. Use this skill when you need to check if any recent changes will cause breaking changes in the CDS public API surface.
Instructions to manage a local cache of GitHub repositories. This would typically done in cases where the user want to perform research/analysis on a repository. Invoke whenever you need to clone a repo that isn't present locally, bring an existing clone up to date, or remove a repo from the cache. This skill handles only the mechanical filesystem/git operations — not research, analysis, or anything about the repo's contents.
| Audits how often deprecated CDS exports are actively used in customer codebases using Sourcegraph MCP search tools. Use this skill whenever asked to assess removal readiness for deprecated CDS APIs, investigate the blast radius of removing a deprecated component or hook, check Sourcegraph for customer usage of deprecated exports, or help the team decide which deprecated APIs are safe to remove in the next major version. Always invoke when asked to "audit deprecated APIs", "check Sourcegraph for deprecated usage", "find usages of deprecated exports", "analyze deprecation impact", or any similar request involving CDS deprecations and customer adoption.
| Provides a workflow for building and reviewing high-quality React and React Native UI with the Coinbase Design System (CDS). Use this skill to create UI or make visual changes to existing UI with CDS components, tokens, style props, icons, and illustrations. Use it for explicit CDS-adherence audits and reviews, not non-visual logic, data, analytics, navigation, tests, generated code, or refactoring. "perform a CDS audit on our changes", "check our codebase for CDS adherence", "does this feature use CDS well?"
