Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden, and it does disclose two real behavioral traits: execution must be paid/completed, and the result is an RVO plus a signed Verification Receipt. However, it omits auth requirements, failure modes, idempotency, and leaves 'RVO' undefined, so the disclosure is partial.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short, but the opening 'R/IV evidence.bundle —' redundantly restates the tool name and consumes front-loaded attention, and the second sentence is dense with unexplained acronyms (RVO, R/IV) rather than useful structure. No sentence is extraneous, but the priority ordering is poor.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With zero parameters, no annotations, and no output schema, the description is the sole source of information, and it is insufficient: it never defines RVO or the receipt format, never explains what evidence is bundled or how verification is judged. An agent would be guessing at invocation preconditions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema is an empty object with zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. No parameter-level meaning is claimed or needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description labels itself an 'independent evidence-verification primitive for evidence', which largely restates the tool name rather than stating a concrete verb+resource action. It never explains what 'bundling' evidence actually does or how it differs from the many sibling verifiers (citation.verify, source.verify, agent.action.verify, evidence.monitor). An agent cannot distinguish this from its neighbors.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance is given, and no alternatives are named despite ~34 sibling tools with heavily overlapping verification semantics. The only implicit cue is 'completed paid execution', which hints at a prerequisite but not a selection condition.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
