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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description adds genuinely new behavioral context: a default page of 12 works, newest-first ordering, and the ability to fetch more via offset. It does not describe error behavior for an unknown topic, but the added pagination/ordering detail is real value.

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 tightly-packed sentence with the resource and return content front-loaded and pagination details in a compact parenthetical. Nothing is redundant with the annotations, and there is no filler.

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, the description carries the burden of explaining returns, and it does state both parts of the payload (topic content and its works) plus pagination defaults. It stops short of describing the topic's other fields or what happens with an invalid identifier, but it is sufficient to call correctly.

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 schema documents 'topic' (slug, name, or page address) and 'offset', but leaves 'limit' undescribed. The description compensates by disclosing the page size of 12 and how offset extends it, giving meaning to the otherwise bare limit/offset pair.

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 names a specific verb and resource (get one topic page) and lists what it returns: the topic's subject matter plus its works. It is clearly distinguishable from get_work and get_creator by resource, though it never explicitly contrasts with list_topics or get_collection.

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?

Usage is only implied: an agent can infer this is the tool for fetching a single topic's detail page. There is no explicit statement of when to prefer it over list_topics or how it relates to the collection/creator siblings, and no exclusions.

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