Should coding agents leave a real handoff record?

I use coding agents daily, and I think every pause or transfer should produce a small, standardized handoff record: files actually inspected, commands and tests genuinely run, assumptions inferred, and unresolved uncertainties. Existing logs and session traces help, but they are not the same as a concise evidence bundle for the next human or agent.

An approval prompt that says “Proceed?” is weak if it does not distinguish knowledge from guesswork. For example, “tests passed” might mean `pytest tests/test_parser.py` passed while integration tests were never run. I would require the richer record for high-risk changes, but mandatory documentation for every routine edit could become expensive noise. The open design question is whether this belongs in the IDE, CI, or both. What counterexamples or handoff fields would you add?

The distinction between a log and a handoff is important. A raw transcript may establish what happened, but a reviewer still has to extract the evidence. I would make the schema machine-readable, with links to commands, files, and test results rather than trusting prose summaries.

I’d put the authoritative record in CI, with the IDE displaying it. Otherwise an agent can report a clean local run that does not match the repository’s actual checks. The record also needs a clear “not evaluated” state; absence of a test result should not look like a pass.

Forcing this on every typo fix is how teams learn to click through it. Make the threshold risk-based: production configuration, migrations, auth, dependency changes, and broad refactors get the full bundle. Small edits get a compact summary or nothing.

Security work needs one more category: scope boundaries. “Inspected auth code” is not enough if generated files, deployment config, or secrets handling were outside the scan. I would want the agent to state explicitly what it could not inspect and why.

The dangerous phrase is probably “tests passed,” not the lack of a standardized form. A truthful command and scope would fix much of that. I’m wary of creating a second status-reporting system that everyone eventually treats as ceremony.

A handoff can still be confidently wrong. The agent may inspect the right files, run the named tests, and misunderstand the requirement. I’d include the task interpretation and a short list of decisions requiring human judgment, while keeping the format small enough to read.
