How does this improve Claude's performance?

By providing a pre-parsed map of exports and imports, Claude can navigate the project structure instantly and understand module dependencies without having to manually read every file in the repo.

When should I run the map command?

You should invoke the mapper when starting work on a new project, after significant architectural changes, or when adding many new modules to ensure the AI's context remains accurate.

Which languages does phi-mapper support?

It currently supports TypeScript/JavaScript (.ts, .js, .tsx, .jsx, .mts, .mjs), Python (.py), and Solidity (.sol).

What is the benefit of the S-expression format used by this skill?

S-expressions provide a compositional, human-readable structure that is easy for AI agents and tools like LIPS to parse and query efficiently compared to flat text.

Does this skill modify my source code?

No, phi-mapper is low-risk. It only creates or updates files within the .phi/ directory and does not alter your actual source files.

Developer Tools

Generates deterministic structural maps of codebases via AST extraction to provide Claude with deep architectural awareness.

Phi Project Mapper automates the creation of PROJECT-MAP.auto.scm files by parsing source files in TypeScript, JavaScript, Python, and Solidity. By extracting named exports, imports, and module relationships into a structured S-expression format, it enables AI agents to understand complex repository architectures without re-parsing every file. This skill is essential for bootstrapping new projects, managing large-scale refactors, and maintaining cross-session structural memory within the Claude Code environment, ensuring that the AI has a clear 'mental map' of the entire project structure.
