Capture session knowledge into structured entries and consolidate them into durable guidance, author paste-ready hand-off briefs, convene fresh-eyes review panels, audit a large file corpus by blind fan-out, maintain a compaction-surviving control anchor for long autonomous runs, behaviorally evaluate skills, keep live awareness of the installed toolkit, sign agent-assisted work with machine-generated provenance trailers (exact model + versioned tool stack, never a co-author line), and run the tool-dogfooding feedback loop: per-session feedback reports captured into each tool's repo and triaged into leverage-ordered improvement backlogs.
