Design, build, document, and ship SDKs that developers love. Covers the full SDK lifecycle — from API surface design and type safety through implementation, bundling, documentation, versioning, and publishing. Use this skill whenever someone is creating a new SDK, extracting shared code into a client library, improving SDK developer experience, planning a breaking change or migration guide, or reviewing an SDK for quality. Also activates for questions about error message design, client library patterns, type-safe API design, SDK packaging (ESM/CJS), or npm publishing.
Build CLI tools and API utilities that developers on your platform actually use. Covers CLI design (command hierarchy, flags, completions, cross-platform UX) and API collection generation (Postman/OpenAPI from Express, Next.js, Fastify, Hono routes). Use this skill when building a developer-facing CLI tool, adding subcommands or flags, implementing shell completions, designing interactive prompts, generating Postman collections from code, creating API testing artifacts, or building any developer utility. Also activates for questions about argument parsing (commander, click, typer, cobra), progress indicators, terminal UX, or Postman collection format.
Build MCP servers that AI agents actually want to use. Covers the full lifecycle — tool design (naming, schemas, descriptions), resource design (URIs, templates, subscriptions), project structure, transport selection (stdio vs Streamable HTTP), security, error handling, and testing. Use this skill when building a new MCP server, adding tools or resources to an existing one, reviewing an MCP server for quality, choosing between stdio and HTTP transport, designing tool schemas for LLM consumption, or hardening an MCP server for production. Also activates for questions about tool naming conventions, Pydantic Field descriptions, Zod validation for MCP, resource URI schemes, or MCP server security patterns.
Design, build, restructure, and ship Claude Code plugins using the modern skills-first + agents + externalized references model. Use this skill when creating a new plugin, writing or refactoring skills, building spawnable agents, externalizing reference material into references/ or docs/, de-emphasizing commands, or asking about "plugin development", "create skill", "write agent", "restructure plugin", "SKILL.md best practices", "references/ in plugins", "agent orchestration", "pr-review-toolkit", "docs-engineering plugin", or the 5 restructure principles. Also activates for questions about lean SKILL.md, progressive disclosure, scalekit-code-doctor pattern, plugin.json, tile.json, or packaging for devex-kit and marketplaces.
Design DX for first success and adoption, choose the right content types (Sample Applications, Code Snippets/Recipes, Solution Patterns), apply "content has a job" and translator principles, and run an effective technical engagement system. Use when working on getting-started experiences, sample apps vs recipes vs patterns decisions, content strategy, onboarding, or DX audits for developer-facing products. Also activates for mentions of "first success", "sample applications", "code snippets", "recipes", "solution patterns", "dx journey", "onboarding", "content has a job", "translator", "share knowledge not features", "technical engagement system", or "dev gtm".
Design authentic stories, recruit and run Technical Advisory Boards (TAB), avoid the 12 most common story mistakes, build dev influencer presence, and define dev-friendly packaging, pricing, and feedback loops for early-stage developer-facing products and startups. Use when working on GTM positioning, launch narratives, TAB outreach, presence strategy, or packaging for devs. Also activates for mentions of "story", "TAB", "12 most common story mistakes", "villain", "sell the category", "authenticity", "presence", "packaging", "pricing for devs", "manager deadline", "ship tonight", "launch story", or "dev gtm".
Diagnose and fix documentation quality problems in cookbook-style writing — skimmability, writing clarity, and reader helpfulness.
Route documentation contributions to the right content type, placement, template, and escalation path — before the contributor writes a single line.
Audit and design documentation sidebar labels and section order so navigation follows a clear developer journey — concise labels, sentence case, and phase-aligned groups (reference model: Full stack auth sidebar in Scalekit developer-docs).
Two-mode writing guide — exports a paste-ready style prompt for coding agents (handoff mode) or reviews a draft against the documentation quality rubric (review mode).
Route tasks and route the user to the correct devex-kit skill before any work begins. Use when starting conversations or tasks that may involve documentation contributions, writing style, cookbook quality, sidebar navigation, SDK design/build/ship, CLI or API tooling, MCP server craft, agent plugin or skill development, devrel storytelling, DX first-success and content taxonomy, or when the user says "using devex-kit", "which devex-kit skill should I use", "help me pick the right skill from the kit", "route this to the right devex skill", or is unsure which /docs-* /sdk-* /mcp-* /devrel-* skill applies. Activates at the start of relevant sessions just like using-superpowers.

Create new skills and iteratively improve existing ones using devex-kit conventions. Use when users want to create a skill from scratch, turn a workflow into a SKILL.md, write or edit a skill, improve skill triggering/description, package a skill for distribution, or follow the lean + references + progressive disclosure model. Also activates for questions about skill anatomy, frontmatter quality, imperative writing style, test cases for skills, or when the user says "create a skill", "write SKILL.md", "improve this skill", "package my skill".
