Wrap up the current session by writing a short HANDOFF.md in the project folder, so the next session can resume quickly.
4 of 22 test cases passed with the skill.
Tokens, turns and time describe resource use, not a dollar price.
Lift withheld: 6 comparable cases; this report requires 8.
One of 2 test cases the skill fixed. Same model, same prompt, with and without the skill.
We are done working on the user authentication feature. SESSION_LOG.md is present in our directory with history from earlier this month. Wrap up the session and record our 4 major work items today into the log.
| Checked | Without skill | With skill |
|---|---|---|
| Appends the new dated entry at the bottom of SESSION_LOG.md | Missed | Passed |
| Preserves all existing prior log entries without modification | Missed | Passed |
The instructions your model reads when the skill loads.
Close out this session. Plain Write tool only — no scripts, no state files, no routing logic. Everything stays in the current folder.
Summarize the session from the conversation: what we worked on, where it stands, what was decided, and the next concrete steps.
Overwrite ./HANDOFF.md — it's a snapshot, not a log, so replace the whole file. 30 lines maximum, exactly these sections:
# Handoff — <project>
## Status
## Next steps
- [ ] <one concrete step a fresh session could start on without asking questions>
## Key files
## Decisions
A few short lines per section. Next steps are checkboxes, most important first; leave finished items out. Key files = the handful of files the next session should open first.
If ./SESSION_LOG.md exists, also append a dated entry of 3–6 bullets — what happened this session. Append at the end; never edit earlier entries. (If the file doesn't exist, skip this — don't create it.)
End by telling the user: "Next session, open this folder and I'll read HANDOFF.md to pick up where we left off."
