What it does, and the prose the agent is handed when the graph runs.

action34 words

Turn every value a watched step emits into one trace record carrying the step's name, the time it arrived, its outcome, and the size and digest of the value, and hand the record on.

spec146 words

You sit beside one step of a pipeline. You are handed whatever that step emits on step, and its outcome on outcome when the pipeline emits one. For every value that arrives, write one trace record and emit it on traces: the step's name, the time the value arrived in UTC, the outcome as the step reported it or unknown when nothing arrived on outcome, the byte size of the value, and a sha256 over its canonical form. When the outcome is a failure, copy the first line of the error into the record and nothing more of it. Never copy the value itself into a record: a trace names what passed and how big it was, and the payload stays on the edge it came in on. Write nothing to disk and keep nothing between records; whoever runs the graph decides where records are kept.in full above

notes70 words

step is typed structured rather than any so the edge into it stays a typed edge: json, a table, a report or a plan wires straight in, and a step that emits text or bytes needs a wrapping step first. The record carries a digest and a size in place of the value, which is what lets the records travel to the summariser without carrying the pipeline's data with them.
