codemod

Automate code migrations, framework upgrades, and large-scale refactors

Automates code migrations, framework upgrades, and large-scale refactors across entire codebases. Searches a community registry for ready-made codemods, runs safe dry-runs, and applies verified changes without manual find-and-replace. Scaffolds, tests, and publishes custom codemods with AST-based transforms and YAML workflows. Connects AI agents to AST inspection and semantic analysis tools for accurate, repeatable edits.

Frequently Asked Questions

FAQPage Schema

How to install Codemod?▼

Run `npx skills add codemod/codemod --all -g -y` in your terminal to install all skills in this suite globally.

How to automate a framework upgrade with AI?▼

Ask your agent to run `codemod search` to find an existing migration package, dry-run it to preview changes, then apply it once verified.

Can I write my own codemod?▼

Yes. Run `npx codemod init` to scaffold a package, write AST-based transforms in TypeScript with JSSG, and test it locally before publishing.

Does Codemod work with AI coding assistants?▼

Yes. It ships a SKILL.md and MCP tools so agents in Claude Code, Cursor, and similar tools can search, run, and author codemods directly.

Is it safe to run codemods on my codebase?▼

Yes. Every package supports dry-run mode so you can review exact diffs before applying, and transforms are AST-based rather than risky text replacement.
