The tools are mostly distinct, but verify_text, check_safety (with optional hallucination detection), and verify_agent all overlap on claim-level hallucination verification. check_cua_actions is clearly separate, but an agent could struggle to choose between the three text/agent verification tools without reading descriptions closely.

All tool names follow a clear lowercase snake_case verb_noun pattern with either check_ or verify_ prefixes. The naming is predictable, though the repeated verbs slightly undercut distinctiveness because verify_text and verify_agent share the same verb while having some overlapping functionality.

Four tools is a well-scoped surface for a safety/verification server. Each tool represents a distinct capability area: free-text verification, agent action safety, general prompt/output safety, and agent trajectory self-check.

The surface covers the core workflows: verifying claims, checking agent actions, scanning prompts/outputs for safety risks, and self-checking agent trajectories. Minor gaps exist—such as no dedicated quota/status tool or a more granular single-claim verification endpoint—but agents can work around these using the existing tools.
