What is a skill?

A skill is a reusable workflow you install into Claude Code once and then call with a slash command. Skills don't replace Claude — they teach it a specific way of working (e.g. how we deploy, how we design schemas, how we run UAT) so you don't repeat the same instructions every session.

  build a TypeScript API sandbox from C# or Postman, end-to-end

  Type this in Claude /create-sandbox

  End-to-end pipeline for building a TypeScript sandbox implementation of an existing API. Translate C# types and controllers to TypeScript (or infer types from a Postman collection), design the sandbox architecture, scaffold the multi-sandbox infrastructure, then implement service methods one at a time with integration + contract tests generated and run automatically.

  ~1-2 days of manual scaffolding per API advanced

  Pin

  Use this when... you need a working TypeScript sandbox of an existing API — for front-end work against a stable stub, integration testing, or contract validation. Starts from C# source or a Postman collection.

  multi-agent build orchestrator

  Type this in Claude /team

  Orchestrates a multi-agent team — refiner, scanner, investigator, planner, designer, parallel coders, reviewer, dependency validator, test builder, integration verifier — to take a request from idea to merged code in one sitting.

  ~half a day per feature-sized request both

  Pin

  Use this when... you have a feature-sized request — bigger than a one-line fix, smaller than a multi-week project. It runs the full ten-phase pipeline (plan, design, code, review, test, verify) in one sitting.

  deploy to NBG Azure

  Type this in Claude /deploy

  Automates end-to-end deployment of NBG Azure-hosted web applications via the Azure Management Portal REST API — first-deploy (provision), auth-setup (identity team credentials + proxy + Kafka), and redeploy (rebuild + push).

  ~45 min per deploy; ~half a day for a first-deploy advanced

  Pin

  Use this when... shipping to NBG Azure — provisioning a brand-new app, wiring identity-team auth and Kafka audit, or pushing changes to an existing one. Skips the click-through portal grind.

  User Acceptance Testing system

  Type this in Claude /uat-panel

  Conversational UAT — Claude walks a non-developer through validating a built feature, asks scripted questions, and records pass/fail evidence the team can sign off on.

  both

  Pin

  Use this when... the app is ready for business UAT — Claude walks the reviewer through each acceptance criterion live and produces a clean pass/fail sign-off record.

  distinctive UI generation

  Type this in Claude /frontend-design

  Anthropic's official frontend-design skill — generates production-grade components and pages with distinctive visual choices, avoiding the generic "AI-slop" aesthetic that gives away machine-generated UIs.

  ~1-2 hours per page both

  Pin

  Use this when... you want a frontend that looks intentional, not algorithmic — when Claude's default Tailwind-card-and-shadow output would give away that a human didn't sit at the keyboard.

  Get Shit Done framework family

  Type this in Claude /gsd-*

  A light-weight meta-prompting, context-engineering and spec-driven development system for Claude Code. A family of commands (`gsd:new-project`, `gsd:plan-phase`, `gsd:execute-phase`, `gsd:progress`, etc.) for managing multi-week projects with persistent `.planning/` state and per-phase artefacts.

  ~half a day per phase on multi-week projects advanced

  Pin

  Use this when... Use this for multi-week projects where you'll pause, resume, and need an audit trail. Persistent `.planning/` folder with roadmap and per-phase artefacts. Overkill for one-sitting work — try `/team` instead.
