Practical skills that help developer agents do high-quality software work.
Works with Claude Code, Codex, Cursor, and any agent that reads SKILL.md.
npx skills add cosmtrek/ultradevTo install a single skill instead of all:
npx skills add cosmtrek/ultradev/simplify-changes| Skill | Description |
|---|---|
| simplify-changes | Review changed code for reuse, quality, and efficiency, then fix issues found |
| teardown | Read a project and produce three ASCII diagrams (context, container, main-flow sequence) showing its inner anatomy |
After installation, invoke a skill by name in your agent:
/simplify-changes
Or ask the agent to use it:
run simplify-changes on my current changes
Each skill lives in its own directory with a SKILL.md file:
ultradev/
<skill-name>/
SKILL.md
This repository is focused on skills for software development work, including:
- code quality and cleanup
- implementation workflows
- debugging and verification
- refactoring and maintainability
- testing and release readiness
Each skill should be narrowly scoped, operational, and useful in real development workflows. If a proposed skill does not clearly improve software quality or developer effectiveness, it probably does not belong here.
