What Retrospective Harness does

description: Trigger deterministic retrospective analysis of recent agent trajectories, extract invariant friction signatures, enforce idempotency constraints, and generate a prioritized Harness Improvement Plan (HIP).

Retrospective Harness Command

Analyze recent execution sessions, command logs, tool failures, and user corrections to formulate a prioritized **Harness Improvement Plan (HIP)** grounded in deterministic tooling and universal idempotency constraints.
