Scored across 2 tools
check_drift targets a specific pinned-hash comparison, while inspect runs a broader multi-stage audit. The overlap is limited to schema evaluation, but an agent might still wonder whether inspect includes drift detection, causing minor ambiguity.
Both tools share the actionguard_ prefix and use snake_case, but check_drift follows a verb_noun pattern while inspect is a bare verb, creating a minor inconsistency.
Two tools is on the low side for a protocol inspector; while each has a clear purpose, the surface feels thin and could benefit from additional operations like baseline management or report retrieval.
The server lacks any tool to set or update the pinned Dual-Hash required by check_drift, leaving a dead end. Core inspection tasks are covered, but baseline lifecycle and result retrieval are missing.

It flags what agents misread (vague parameters, writes marked read-only), what breaks clients or prompt caches (tools that appear mid-session, schemas that change on every call), and breaking changes between releases with the version bump they need.
