# what — explain the concepts, not the timeline
A session ends. The work is done and the summary is accurate, and you still
cannot review the next PR in that area, because eight of the nouns were new.
That gap does not close by re-reading the summary. It closes by someone naming
the eight nouns and defining them.
Nothing else in the stack does this. Bridge (P1) records *what happened*.
`/handoff` writes *state for the next agent*. `/comprehend` runs a multi-stage
teach-to-mastery loop. `/what` is the fast one: **the vocabulary of the last
stretch of work, explained once, grounded in where it actually appeared.**
## The one rule
> **Concepts, not chronology.**

> If the answer reads "first I did X, then Y, then Z", it is a session log and
> it has failed. `/what` is organised by *idea*, ranked by *what blocks
> understanding* — never by what was hardest to build or said most often.
## Scope
`/what` explains **everything since you last asked** `/what`. One rule covers
both cases:
| You fire it | Slice | Behaviour |
|---|---|---|
| After a long arc | since the last `/what`, else the whole session | full concept inventory |
| Right after one dense message | that message | the re-pitch case (below) |
| `/what <term>` | the whole session | one concept, in depth |
| `/what --scope session` | whole session, markers ignored | full inventory |
**The re-pitch case.** When the slice is short or plain, the script returns an
empty inventory. That is not a failure — it is the signa
