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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real value beyond that: it scopes the read to readiness/identity only, explicitly disclaims side effects ('No model, wallet or trade call'), and warns that a config-ready result is not evidence of a fresh evaluation or settlement — a substantive caveat about how to trust the output.

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?

Three short sentences, front-loaded with the read action, followed by two caveats that each carry information. Slight deduction because 'decision-only service identity' is compressed to the point of ambiguity and reads as jargon rather than precision.

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 no parameters and rich annotations, most of the burden is already handled, and the negative-capability and trust caveats help. But there is no output schema and the description never indicates what the readiness/identity response contains, which is the main thing an agent lacks when deciding what to do after calling it.

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 and the baseline of 4 applies. The description correctly implies the call is argument-free.

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 verb 'Read' is present and the object is 'current readiness and decision-only service identity', which places it as a status/inspection tool rather than a decision or evaluation tool among the verdict_* siblings. However, 'decision-only service identity' is opaque jargon and 'readiness' of what is never defined, so an agent still has to guess what the tool actually surfaces.

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 explicit when-to-use statement and none of the sibling tools (verdict_decide, verdict_compile_capsule, verdict_verify_capsule) are named as alternatives. The line 'Configuration readiness is not proof of a fresh Jev evaluation or settlement' is an interpretation caveat, not routing guidance, so it only weakly implies when this tool is appropriate.

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