Pi Ast Grep

pi-ast-grep

[](https://github.com/code-yeongyu/pi-ast-grep/actions/workflows/ci.yml) [](LICENSE)

AST-aware code search and rewrite for the [pi coding agent](https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent). Faithful port of the ast-grep tool stack from [oh-my-openagent](https://github.com/code-yeongyu/oh-my-openagent).

Origin

This package is a port of the ast-grep tools originally written for [oh-my-openagent (omo)](https://github.com/code-yeongyu/oh-my-openagent) by Yeongyu Kim ([@code-yeongyu](https://github.com/code-yeongyu)). The omo source for the tools lives at `src/tools/ast-grep/` in that repository.

The same author re-licensed the ported source under MIT for distribution in the pi-coding-agent ecosystem. omo itself remains under SUL-1.0; this package's MIT scope covers only the code that ships in this repository. See [LICENSE](LICENSE) and [NOTICE](NOTICE).
