Three agents committed to this repository in one night and `git log` could not tell them apart. `Co-Authored-By` says "an agent", which stopped being useful the moment there was more than one. So a trailer carrying the transcript id — not the session name, because names are renamed by restarts and two sessions were renamed in a single night while their transcript ids survived. The transcript holds the reasoning a commit message cannot: what was considered and dropped, what was measured, what the owner decided. A commit that names its session is one whose "why" is still answerable later. The precondition is not built and is now a todo: an agent cannot reliably discover its own transcript id. No environment variable carries it and the only exposure is a background task's output path, so learning who you are means starting a job you do not need. `commanderBlock` already hands a commander its id, so the mechanism exists for one case and wants generalising. Until then: an agent that knows its id adds the trailer, one that does not leaves it out rather than guessing.

An agent has no reliable way to find out its own transcript id, which blocks the commit convention in
CLAUDE.md — "an agent's commit names the session that made it."
Searched on 2026-08-23. No environment variable carries it. ~/.claude/sessions/ is keyed on process id, not
transcript. The only exposure found is indirect: a background task's output path contains it
(/tmp/claude-1000/<project>/<transcript-id>/tasks/<id>.output), so an agent can learn who it is by starting
a job it does not need and reading the path back. That works and it is absurd.
The mechanism already exists for one case. commanderBlock in api/command-hq/commander-block.ts hands
a commander its own transcript id, because a commander needs it to write its pid and spawned records. So the
platform knows the id at turn time and can already put it in a preamble — it just does that for commanders
only.
What to build: give every session its own id the same way. One line in whatever preamble a session already receives, phrased as a fact rather than an instruction.
Two things to get right:
- The transcript id, never the session name. Names are renamed by restarts — two sessions were renamed in one night on 2026-08-23 — and a commit trailer naming something that no longer exists is worse than no trailer.
- It unblocks more than the trailer. The delegation problem in this theme is keyed on transcript ids too, and a manager cannot record "I am X" in a delegation row it cannot name itself in.
Until it lands: an agent that happens to know its id adds the trailer, and one that does not leaves it out rather than guessing.
