Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.
incremental-implementation
incremental-implementation is an open-source productivity skill for Claude Code and compatible agents, published by addyosmani. Its author describes it as: “Delivers changes incrementally. Use when implementing any feature or change that touches more than one file. Use when you're about to write a large amount of code at once, or when a task feels too big to land in one s…”. The project has 88k stars on GitHub and is available under the MIT license. Add it to your setup with `/plugin marketplace add addyosmani/agent-skills`.
What incremental-implementation does
Build in thin vertical slices — implement one piece, test it, verify it, then expand. Avoid implementing an entire feature in one pass. Each increment should leave the system in a working, testable state. This is the execution discipline that makes large features manageable.
Installation
Add incremental-implementation to your agent with:
/plugin marketplace add addyosmani/agent-skillsAlways review a skill's source before installing it. This command comes from the skill's public repository; the linked repo is the source of truth for exact setup steps.

Frequently asked questions
- What does incremental-implementation do?
- Delivers changes incrementally. Use when implementing any feature or change that touches more than one file. Use when you're about to write a large amount of code at once, or when a task feels too big to land in one step.
- How do I install incremental-implementation?
- Run /plugin marketplace add addyosmani/agent-skills in your agent, then reload your skills. Review the source at https://github.com/addyosmani/agent-skills before installing.
- Is incremental-implementation free to use?
- Yes. incremental-implementation is free and open source under the MIT license, so you can read, run, and adapt it within that license's terms.
- Where does incremental-implementation come from?
- incremental-implementation ships inside addyosmani/agent-skills, a repository that contains 25 catalogued skills in total. The repository's 88,280 GitHub stars apply to that whole collection, not to this skill on its own.
