AI coding session died before the work was finished
The worst moment is not the crash. It is opening a new chat and realizing the next AI has no idea what changed, what failed, or what step was supposed to happen next.
Why this hurts.
The old chat may be gone, rate-limited, closed, or too broken to summarize. If the working state only lived in the transcript, the next session starts blind.
How ShardStitch solves it.
Confirm the checkout that survived
Scan local project state: git diff, changed files, recent commits, notes, and project memory.
Build an evidence-based continuation packet
Build a continuation packet with current goal, known facts, inferred next steps, risks, and next action.
Mark unavailable conversation details
Label decisions or attempts known only from the old conversation as unknown unless local notes preserve them.
Resume with one verifiable action
Give the next AI a concrete first action and its check, then inspect the result before more edits.
What the next AI receives.
- Current goal and task boundary
- Changed files and risky files
- Recent commits and local edits
- Verification state and next action
What stays out.
- Full transcript replay
- Old debugging branches
- Dead-end reasoning that changed no decision
- Claims not backed by disk or clearly marked as inferred
First response: recover before restarting
FAQ.
Can ShardStitch restore a conversation that disappeared?
No. It can help prepare a continuation from surviving project evidence. A decision kept only in the missing conversation may not be recoverable and should remain marked unknown.
What should I verify before the next AI edits the project?
Confirm the repository root and branch, review the current diff, and determine whether the last command or test actually finished. Then provide the current handoff and re-check its claims.
