Pull request overview
This PR fixes session synchronization failures when folder names contain special characters (underscores, dots, etc.) by implementing path normalization that matches Claude Code's .claude/projects folder naming convention.
Changes:
- Added
normalizePathForKey()utility function to convert paths to Claude Code's naming convention (replacing special characters with hyphens) - Updated session/project key generation in
sessionUtils.ts,projectManager.ts, andgitStatusSync.tsto use normalized paths - Added comprehensive test suite with 214 test cases covering edge cases including Unicode, Windows paths, and special characters

Normalizing the path here makes the project key lossy, so two different directories on the same machine that differ only by characters you replace (e.g., /Users/dev/foo_bar vs /Users/dev/foo.bar, or double-hyphen vs single-hyphen) now collapse to the same key. That causes project grouping, git status sharing, and session management to merge unrelated projects. This is a new behavioral regression introduced by the normalization; if the goal is Claude Code compatibility for sync, you may need a separate normalized key for matching while preserving a lossless key for local project identity.
Useful? React with 👍 / 👎.

Good catch. I've reworked the implementation — the new version uses Claude Code's exact regex (/[^a-zA-Z0-9]/g) without collapsing consecutive hyphens or stripping trailing ones, which the previous version incorrectly did.
The collision concern (e.g. foo_bar vs foo.bar) is inherent to Claude Code's own algorithm — it does the same lossy replacement. So the mobile app now behaves identically to Claude Code itself. Since the goal is to match Claude Code's .claude/projects folder names for sync, using a different (lossier or less lossy) algorithm would actually break things.
I also scoped down the change — getSessionAvatarId no longer normalizes since it's purely cosmetic and doesn't need to match Claude Code's keys.

The highest github issue we have #405 , Where did you find these github issues?

Yeah those were hallucinated by the AI co-author when generating the test cases. Removed them in this update — the tests now just describe the behavior without referencing any issue numbers. Sorry about that.

What are we missing here to get this PR merged? I would love to have the sync working 😭 |
Claude Code normalizes project paths with: path.replace(/[^a-zA-Z0-9]/g, '-') without collapsing consecutive hyphens or stripping trailing hyphens. Previous implementation used a different regex that diverged on edge cases (trailing slashes, consecutive special chars). This version exactly matches Claude Code's behavior verified against @anthropic-ai/claude-code source. Changes: - Add normalizePathForKey() matching Claude Code's exact algorithm - Apply to projectManager and gitStatusSync for correct session grouping - Do NOT apply to getSessionAvatarId (cosmetic only, no sync requirement) - Add test suite covering common paths and edge cases Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Just force-pushed a rewrite that's rebased on latest main (monorepo structure) and fixes the issues from the review:
Should be ready for another look now. |
