# reflect — turn a finished session into durable learnings

A long session teaches things that die with it: the guidance that was missing,
the command that cost four retries, the thing you did that no skill describes.
`/reflect` reads the transcript of the session it was invoked from and proposes
each durable learning as a change someone can accept or reject. Three things
make it more than "summarize this session":

- **It reads the session, not its own memory.** Compaction has already
  discarded the early turns from context, and those turns are where the
  corrections live. So the run resolves the session's transcript on disk and
  works from that file.
- **Three lenses, then one list.** The lenses look for different things and
  report what they find. Sorting the findings — accepted, rejected, or handed
  to the tracker — happens once, afterwards, so one finding cannot be
  classified three ways.
- **Nothing mutates before you answer.** The read-and-plan phase writes only
  inside its own run cache and prints where. Every change to a file you own,
  and every issue on a tracker, waits on an explicit approval.

Model invocation is disabled (`disable-model-invocation: true`). A run rewrites
`SKILL.md` files that every future run reads and creates issues that are public
and irreversible, and no verification afterwards undoes either. Only a
deliberate invocation starts it. `agents/openai.yaml` restates the same guard
for Codex as `policy.allow_implicit_invocation: false`.
