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.

Look at real hardware, screens, panels, and wiring on a desk or workbench through a camera, so Claude can SEE physical output that no unit test, log, or API can. Use whenever the user says "are you seeing this?", "olha isso", "look at this", "watch this", "can you see...", "check the camera", "look at the screen" / "look at the display", "is this wired right?", or "what's this part?"; asks to visually verify a rendered display, LCD, LED, or panel; wants a wiring, polarity, or voltage-rail check before power-on; or needs to confirm a font, layout, clipping, or on-screen value renders correctly instead of trusting green tests. Grabs the current camera frame(s) and reads them; supports a watch mode for an action in progress. Needs a snapshot-capable camera reachable over HTTP (Android IP Webcam app, Raspberry Pi camera-streamer, or any snapshot URL) set via CCE_CAM_URL.
Crée une nouvelle branche Git à partir de la dernière version de main, avec un préfixe conventionnel feat/ (nouvelle fonctionnalité) ou fix/ (correction de bug).

| Scaffold iOS apps with Tuist and layered architecture (Domain, Infrastructure, App). (3) User asks to "create an iOS app", "scaffold an app", or "set up a new Swift project", (4) User wants layered/clean architecture for iOS, (5) User mentions Tuist setup.
Full-lifecycle guide for implementing a feature end-to-end in a London-school DDD Swift/iOS codebase (or any layered Domain/Infrastructure/App project that uses protocol + concrete impl aggregates, narrow infrastructure ports, and Chicago-school state-based TDD). Use this skill whenever the user asks to **build**, **implement**, **add**, **ship**, or **develop** a feature — including vague asks like "let's add X", "build me Y", "implement Z", or "wire up the W flow". Strongly prefer this skill over jumping straight to code whenever a new domain concept is in play. Each lifecycle phase has its own focused sub-guide so the agent loads only the instructions for the current task, not a 600-line monolith.

Drive a Metabase instance from the terminal via the `mb` CLI. Authenticate with named profiles; inspect databases (list, get, full metadata rollup, schemas, tables in a schema) and trigger manual schema sync / field-values rescan; inspect tables, fields; list/get/create/update/archive cards (questions, models, metrics) and run them as JSON/CSV/XLSX; list/get/create/update dashboards and patch dashcards; list/get/create collections and traverse the hierarchy by id, entity_id, or "root"/"trash" (with items and recursive tree); list/get/create/update/archive native query snippets, segments, and measures; author/update/run transforms and schedule transform-jobs; read/update settings; search content (cards, dashboards, collections, transforms, metrics); manage Enterprise workspaces; git-sync to/from a git remote (status, dirty, import, export, branches, stash, add/remove a collection from sync).
