Scaffolds a Node.js REST API with typed routes, plugin structure, JSON Schema validation, error handling, and middleware setup — all in TypeScript or JavaScript.

Configures ESLint v9 with neostandard rules for JavaScript and TypeScript. Migrates from old .eslintrc files and troubleshoots lint errors without fuss.

Reads segfault logs and binding.gyp errors, spots memory leaks in C++ addons, and suggests fixes for node-gyp build failures and event-loop bottlenecks.

Generates boilerplate for authorization-code flow with PKCE, refresh tokens, and JWT validation—handles the OAuth plumbing so you don't expose secrets or miss a grant type.

Takes your README fragments, help pages, and API notes and sorts them into tutorials, how-to guides, reference sections, and explanations using the Diátaxis framework.

Scans your repo structure and codebase, then drafts an AGENTS.md with the unwritten rules, quirks, and conventions Claude needs—without bloating it with stuff already obvious from code.

Scaffolds a Node.js project with TypeScript, async patterns, error handling, and logging already baked in. Includes setup for testing, caching, and performance monitoring.

Pastes code and generates a polished, syntax-highlighted PNG or SVG with your choice of theme, line numbers, and styling — ready to drop into docs, tweets, or blog posts.

Scans your codebase for `any` types and `any`-adjacent patterns, then rewrites them as strict generics and type guards that preserve all the flexibility without killing type safety.

Paste a GitHub URL—issue, PR, commit, or repo—and run any git or gh CLI operation against it without typing commands. Handles cloning, checking status, merging, and CI/action logs.

Runs a skill through systematic evals—clarity, activation rate, cross-model reliability—and returns specific rewrites to the trigger, instruction, and examples that lift each score.
