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 genuinely useful traits: execution is paid, and a completed run returns an RVO plus a signed verification receipt. However, it never explains what 'paid' entails (cost, auth), what an RVO is, or what happens on failure, so the disclosure is partial jargon rather than actionable behavior.

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 and the behavioral sentence is front-loaded in the second clause, but the leading 'R/IV evidence.monitor —' redundantly echoes the name/title, and the acronym-laden phrasing spends words without adding meaning. No filler beyond that, but the first sentence is close to tautology.

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?

For a verification primitive with no annotations and no output schema, the description should explain the verification model and distinguish it from siblings; instead it leaves undefined terms (R/IV, RVO, 'signed receipt') and no routing. It is insufficient for an agent to invoke it correctly in a dense verification toolset.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for 0-param tools is 4. Schema coverage is effectively complete by virtue of having no inputs.

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 largely restates the name ('evidence.monitor' → 'evidence-verification primitive for monitoring') and wraps it in unexplained in-house jargon (R/IV, RVO). It never states a concrete verb+resource action, and with ~35 siblings in the same verification/monitoring space (evidence.bundle, source.verify, claim.check, agent.monitor), it does nothing to differentiate itself.

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?

There is no when-to-use guidance, no prerequisites, and no named alternative — despite an extremely crowded sibling set of near-identical verification tools. The agent is given no basis for choosing this over claim.check, source.verify, or evidence.bundle.

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