# analyse-recent-sessions — Mine Recent Worker Traces for Patterns
Use when a hygiene worker has scrollback and event-log access to a window of recent worker sessions and wants to convert recurring friction into a durable skill update (per the "Pattern Detection & Root-Cause Discipline" rule in `roles/AGENTS.md` / the doctrine loaded by every role).
This skill is the explicit, on-demand counterpart to the stop-hook's `ke-learn`: instead of one session's takeaways, it spans N sessions and looks for shape.
Wiring this skill into the stop-hook reminder (and any bookie hygiene-emit verb) is Slice D's responsibility — until that lands, workers reach this skill by directory listing or by an explicit pointer from the director.
## When to use
- ≥3 recent worker rows showed the same failure mode, the same wasted exploration, or the same hand-holding question.
- A new skill landed recently and you want to check whether workers are actually invoking it correctly.
- The director suspects a class of work is consistently over-budget and wants evidence before re-shaping the workflow.
Do **not** use this skill to debug a single failed row — use `triage-failed` for that. The minimum signal here is N≥3 rows showing the same shape.
## Inputs expected
- A time window or a row-id list (e.g. "last 24h of `class=hygiene` workers" or `["row-a", "row-b", "row-c"]`).
- Access to the ledger event log and (where available) tmux scrollback under `~/vault/agents/<role>/journal/`.
- A hypothesis to
