hands_perceive (observe/build element map) and hands_trail (read telemetry) are clearly distinct from the action tools, and hands_act vs hands_run is mostly separable by cardinality (one governed action vs scripted multi-step run). The boundary is slightly fuzzy since a single-step script could be expressed via either act or run, but the descriptions make the intended split readable.

All four tools use the same hands_<verb> convention (hands_act, hands_run, hands_trail, hands_perceive) with concrete, unambiguous verbs. No mixing of casing or verb styles.

Four tools map cleanly onto the core loop of a governed automation driver: perceive the page, act once, run a batch, inspect the trail. Each tool earns its place with no filler or redundancy, and the surface stays small enough to be trivially comprehensible.

The observe → act → batch-run → audit loop is fully covered, including approver-gated consequential actions. Minor gaps exist around session lifecycle (no explicit session start/close/reset) and approval management (approver state only reported indirectly via act responses), which agents can mostly work around.
