Write, refactor, and ship code with an agent that knows your stack.
Most artifacts in the catalog live here: tools that read a codebase, follow its conventions, and make changes you would not be embarrassed to review. Expect language-specific helpers, refactoring workflows, spec-driven development harnesses, and framework-aware assistants for stacks like React, Next.js, Python, Rust, and Go. If you want your agent to stop writing generic code that ignores how your project actually works, start here.
