ShardStitch

"Rate limit reached." "Context window full." "VRAM out of memory."

Your code is half-written. Your plan is in your head. ShardStitch captures your entire session — git diff, changed files, dependency graph, intent — and stitches it into the next AI tool. One hotkey. Keep building like nothing happened.

Install

npm install shardstitch
npx shardstitch

What it does

When Claude, Cursor, Codex, or Gemini locks you out mid-session, ShardStitch:

1. Scans your project — git diff, changed files, recent commits, your notes
2. Builds a dependency graph — impact radius, architecture communities — and warns the next AI what's dangerous to touch
3. Generates a continuation prompt formatted for the target tool
4. Injects it into the tool's pickup file (CLAUDE.md, AGENTS.md, GEMINI.md, .cursorrules) for automatic discovery

Under 30 seconds, end to end.

Not just for switching tools

The same trick fixes a bloated session in the same tool. Long AI chats accumulate a huge context tree — token burn climbs, responses slow down, and eventually you hit "Service is busy" even with quota left. ShardStitch is the clean-restart button: extract a compact context, open a fresh window of the same tool, paste, keep going.
