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

The readOnlyHint annotation already covers the safety profile, yet the description adds genuinely useful provenance semantics: the content is public, machine-readable, provisional theory rather than validated fact, which should change how an agent cites or acts on the output. It still omits return shape and size expectations, which keeps it short of the top score.

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?

Two short sentences, front-loaded with the action and immediately followed by the reliability caveat, with no filler. It is efficient, though the terseness comes partly at the cost of the missing parameter and selection detail.

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 output schema and only a readOnlyHint annotation, the description carries the disclosure burden, and it does convey the nature and reliability of the content. It remains incomplete on the one thing the agent must decide — which of the five sections to request — and on what comes back.

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?

There is a single required `section` parameter with an enum of core, claims, concepts, graph, and questions, and the schema supplies zero description coverage. The description says nothing about what each section yields, so the agent must guess which value to request — a meaningful gap the description does not compensate for.

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 gives a verb ("Read") and a resource ("a public machine-readable provisional Olothea theory module"), so the basic action is identifiable. However, it never clarifies what a "module" actually contains or how it differs from siblings such as research_packets, research_match, or knowledge_catalog, so an agent cannot confidently choose it on purpose alone.

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. The only guidance-like content is the caveat "Not verified scientific facts," which describes the trust level of the content rather than when to call the tool instead of another one.

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