Distill Skill — Session → Skill

Record a CC session, then distill it into a generalized skill via edit-tool. Two modes: forward (record as we go) and retrospective (parse session-so-far).

Modes

Arg	Mode	When
`start`	Forward	User invokes at/near session start. Creates trace dir, annotates turns going forward.
`finalize`	Close out	End of session. Run search-skill dedup, propose split, hand to edit-tool.
`status`	Inspect	Show current trace dir + turn count + friction/confusion tally.
(none)	Retrospective	Parse session-so-far. ⚠️ Warn if compaction may have occurred (turn count high / early context lost).
