Chat transcripts are too noisy to use as handoff state
A transcript is a timeline. A handoff is a starting point. Those are not the same object.
Why this hurts.
Transcripts include abandoned branches, mistaken assumptions, dead ends, and explanations that made sense only at the time.
How ShardStitch solves it.
Extract the task that remains
Build a forward brief instead of a backward summary.
Keep facts that change the next choice
Prioritize disk-backed facts, changed files, tests, and next action.
Discard conversation-only repetition
Trim context so the next AI sees the signal, not every turn.
Validate the brief against the project
Compare the brief's changed files and test claims with the current checkout before writing pickup files or sharing it with another tool.
What the next AI receives.
- Current state
- Repo evidence
- Decision constraints
- Next step
What stays out.
- Chronological chatter
- Wrong turns
- Resolved confusion
- Irrelevant file exploration

FAQ.
Should I include the full chat log in a handoff?
Not by default. Include conversation excerpts only when they preserve a decision or requirement that cannot be checked elsewhere, and label their source and uncertainty.
What makes a transcript summary useful to the next AI?
It should identify the remaining goal, current files, verified outcomes, relevant failed attempts, constraints, and next action. A shorter transcript without those items may still be noisy.
