DeepSeek Harness (DSH) plugin: a read-only ledger for the plugins you already have installed — a capability inventory with file:line evidence, declared-vs-detected reconciliation, cross-profile version drift, and a diff of what changed since the last scan.
DSH plugin: lock, verify and govern AI agent skills. Tells you what a skill can do before you install it — and when it silently gains a capability after your review. Ships no boot-time code.
