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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds nothing beyond that: no note on what the reservation/settlement states mean, no error behavior for an unknown or expired evaluation_id, and no operational context. With annotations carrying the burden, this is still a missed opportunity rather than a contradiction.

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?

A single front-loaded sentence with no filler or redundant restatement of the title. Its brevity borders on under-specification, but nothing in it is wasted.

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?

Low-complexity read tool with one fully documented parameter, an output schema, and rich annotations, so the description need not explain return values. However, the opaque 'reservation/settlement state' jargon is left undefined and the relationship to the settle/release siblings is never stated, leaving a real gap for an agent deciding which tool to call.

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?

Schema description coverage is 100% and the single parameter evaluation_id is documented with meaningful provenance ('returned by an ALLOW verdict'). The description does not touch the parameter at all, so per the high-coverage baseline this sits at 3.

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?

States a specific verb ('Inspect') and a specific resource ('an evaluation') scoped to its 'reservation/settlement state', which is enough to distinguish it from mutation siblings like settle_evaluation or release_evaluation. It does not name any sibling explicitly, so it falls short of a 5.

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 guidance on when to use this tool versus the many sibling tools, no prerequisites, and no indication that state changes should go through release_evaluation or settle_evaluation instead. The agent must infer from the name alone that this is the read-only counterpart.

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