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 fully covered by structured fields. The description's only behavioral value-add is the "what the numbers do not prove" caveat, which usefully flags built-in limitations. Return format is not described, though an output schema exists to carry that.

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 beginning with "Use this to read..." — no preamble or filler. The comma-separated content list is slightly run-on but every item earns its place by telling the agent what is inside.

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?

Zero parameters, complete annotations, and an output schema that covers return values, so the description's job is mainly to explain what content is returned — which it does. Nothing critical is missing for a correct invocation.

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 per the rubric the baseline is 4. There is nothing for the description to disambiguate beyond correctly implying a parameterless full-document read.

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 (read) and enumerates concrete resources: method version, the five engines, definitions used in figures, proof rules, and limitations. That is far more informative than the name alone. It does not, however, distinguish itself from overlapping siblings such as get_proof or get_results, which also surface methodology-adjacent content.

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?

"Use this to read..." implies the tool's role as an orientation/methodology reference, but there is no explicit when-to-use, no when-not-to-use, and no sibling alternative named. Usage must be inferred from the enumerated content list.

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