A collection of reusable agent artifacts — skills, prompts, and more.
If you use Vercel's npx skills, you can install individual skills like this:
npx skills add msewell/agent-stuff/skills/<skill-name>| Artifact | Description |
|---|---|
| api-first-best-practices | Provides instructive best practices for API-first development — designing API contracts collaboratively with consumers before writing implementation code, enforcing contracts in CI/CD, and scaling adoption across teams. Use when advising on API design process, contract testing, mock-driven parallel development, API governance, OpenAPI specs, consumer-driven feedback, or designing APIs for AI-agent consumers. |
| kotlin-functional-programming | Guides writing idiomatic, functional-style Kotlin code using built-in language features. Use when asked to write, review, or refactor Kotlin code for immutability, pure functions, sealed types, error handling, collections, coroutines, or functional architecture patterns. |
| reducing-coupling | Analyzes a codebase scope for coupling issues, diagnoses coupling types using the Connascence framework, and proposes a comprehensive refactoring plan with concrete code changes. Use when asked to find coupling, reduce dependencies, decouple modules, or improve modularity in a codebase. |
| toon-format | Instructs an LLM agent when and how to use TOON (Token-Oriented Object Notation) for encoding and generating structured data. Use when injecting structured data into context, encoding tool results, preparing RAG documents, producing structured output, or advising on TOON integration. |
| tweet-review | Reviews draft tweets and provides engagement optimization recommendations with improved alternatives. Use when the user has a draft tweet or thread and wants feedback on how to maximize reach, replies, and engagement on Twitter/X. Primarily niche-agnostic with additional guidance for tech Twitter. |
