The moment you open the terminal, nobody's conducting

## Spark

Two pieces landed on the same metaphor within days of each other, and the
week's own GitHub activity reads as a stress test of it. Brent Chapman, on
incident command:

> The conductor doesn't play an instrument; the orchestra as a whole is their
> instrument. The moment the conductor picks up a violin, nobody's conducting.
> The same thing happens when an IC opens a terminal.

Rachel Laycock's "The Conductor Developer" applies the same frame to agent-assisted
development. The same week: 23 pull requests and 32 issues opened across six
repos.

## Why it could be interesting

The metaphor says *stop touching the instrument*, and that reads as an argument
for delegation. But the week's issues aren't delegation — they're specification.
"`validateRequestBody` narrows `validatedBody` to the schema-derived type."
"`deserialiseArtifactPlan` rejects partial artifact plans." That is conducting
written down: the judgement stays with the conductor, expressed as an
acceptance criterion precise enough that the section can play it without
further instruction.

So the claim to test is that conducting is a *writing* practice, not an
abstention. The failure mode isn't picking up the violin; it's waving vaguely
and then picking up the violin because the section couldn't read the gesture.
That reframes the throughput question — the ceiling isn't how many agents you
can run, it's how fast you can specify — and it connects to the accountability
line already argued in #357: delegating the playing never delegates the score.

## Open questions

- [ ] Is "conducting is specification" genuinely distinct from #283's
working-pattern evolution, or a chapter of it?
- [ ] Where does the metaphor break? A conductor's score is fixed before the
performance; here the score is written mid-performance.
- [ ] What's the actual evidence that precise acceptance criteria beat
conversational direction — is there a comparison in the genshin history?
- [ ] Does this subsume or sit beside #71 (tracking issues versus
acceptance-criteria issues)? #71 may be the mechanism this post needs.
- [ ] Is the incident-command version the same claim or a borrowed one? Chapman
is arguing about attention under load, not about specification.
