# 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

- **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`.
