What is this?
A builder (identified as dmkii/dumkydewilde) released `/dehistorize`, a reusable agent skill designed to strip edit-history leakage from model outputs — preventing models from oversharing deleted content or anchoring to prior versions. The skill operates at the harness level as a practical mitigation for history-contamination in agent workflows. The web search results do not surface this specific skill or its authors; they discuss agent skills frameworks broadly (Termdock, SkillHone, Claude Skills, Estuary) but not `/dehistorize` itself. The evidence titles confirm the skill's existence and purpose, but the public web has no visible coverage.
Why it matters to Scott
A builder (dmkii/dumkydewilde) releases a concrete, reusable harness skill that strips edit-history leakage — directly implementing Scott's context-hygiene and context-engineering doctrine (predictable forgetting, discard ephemeral workspace) and his skills-and-workflows primitive (reusable, on-demand capability modules). The skill operates at the harness level as a mitigation, aligning with his architectural-containment principle (can't beats shouldn't) and agent-authored-context-compaction pattern (harness discards raw history). This is a consequential other party arriving at a pattern Scott's frameworks already argue for.
