'Fixed' is an unusable engineering handoff. Source, change, proof, uncertainty, owner. It survives ephemeral sessions. #EricFieldNotes
Full written post / accessibility read
An agent can make a patch and summarize it in fluent prose. If the next engineer only receives 'fixed,' they still need to find the source request, changed behavior, actual proof, unknowns and release owner. That reconstruction is costly when the agent's session has already disappeared.
Source states why the work exists and its authority. Change names the actual diff. Proof lists independent tests and environment. Uncertainty names what did not run. Owner accepts release and rollback. For a schema migration, include event versions and consumer readback, not merely a green producer suite.
Give a second engineer the packet without the original chat. Ask them to name the release condition, untested consumer, rollback signal and exact next probe. If they cannot, the handoff lost material context. Keep a link to test traces and named decisions, not a giant transcript dump.
My rule: every agent-assisted change gets a short evidence handoff with source, change, proof, uncertainty and owner. Do this because correctness depends on what the next human can verify and decide after the original context is gone.

Four-beat scene transcript
1. 'Fixed' is an unusable engineering handoff.
An agent can make a patch and summarize it in fluent prose. If the next engineer only receives 'fixed,' they still need to find the source request, changed behavior, actual proof, unknowns and release owner. That reconstruction is costly when the agent's session has already disappeared.
Visual: The next owner must reconstruct the truth.
2. Carry five fields across the boundary.
Source states why the work exists and its authority. Change names the actual diff. Proof lists independent tests and environment. Uncertainty names what did not run. Owner accepts release and rollback. For a schema migration, include event versions and consumer readback, not merely a green producer suite.
Visual: Source, change, proof, uncertainty, owner.
3. Make the packet executable.
Give a second engineer the packet without the original chat. Ask them to name the release condition, untested consumer, rollback signal and exact next probe. If they cannot, the handoff lost material context. Keep a link to test traces and named decisions, not a giant transcript dump.
Visual: A receiver should know the next action.
4. Write the decision receipt before declaring done.
My rule: every agent-assisted change gets a short evidence handoff with source, change, proof, uncertainty and owner. Do this because correctness depends on what the next human can verify and decide after the original context is gone.
Visual: It survives ephemeral sessions.
