Yeah. After a quick pass, these are the main things I would change.

Make git parsing robust in src/git.ts
- Use -z output (git diff --name-status -z, ls-files -z, diff-tree -z) and parse NUL-delimited fields.
- Current parsing uses trim() and split("\t"), which can break for odd but valid file names.
Move binaryExtensions out of isReviewableFilePath in src/git.ts
- It is recreated on every call.
- Hoist it to a module-level const Set for less allocation pressure.
Use a Set for currentPaths membership checks in src/git.ts
- This line is currently currentPaths.includes(change.newPath) inside a loop.
- For large repos, replace with const currentPathSet = new Set(currentPaths) and currentPathSet.has(...).
Validate host/window messages in src/index.ts
- const message = data as ReviewWindowMessage trusts unknown input.
- Add runtime shape checks before branching to avoid malformed-message crashes.
Add test coverage for core logic
- src/git.ts: parseNameStatus, merge behavior, scope selection logic.
- src/prompt.ts: prompt formatting and location formatting.
- This project has high-value pure logic that is easy to unit test.
Ignore local tooling artifacts
- Add .pi/ to .gitignore (currently only node_modules/ and sessions/).
- Prevents accidental commits of local agent/session data.
Optional product improvement
- Bundle Monaco/Tailwind locally instead of CDN in web/index.html.
- Removes internet dependency and improves reliability in restricted environments.

If you want, I can turn this into a concrete prioritized patch plan (quick wins first, then structural changes).
