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

Beyond the readOnly and idempotent annotations, the description discloses the conditional behavior of listing sections when no topic is provided, and explains the practical relevance of the guide's content. This adds meaningful behavioral context without contradicting the annotations.

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?

The description is two sentences and front-loads the guide's scope, followed by the key usage instruction. Every sentence earns its place, and there is no redundant or filler content.

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?

The description covers what the tool reads, what topics are available, the optional-topic behavior, and the most important usage context. Since there is no output schema, a brief mention of the return format would have made it fully complete, but the tool is simple enough that the current definition is sufficient.

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 coverage is 100%, so the parameter is already fully documented. The description reinforces the behavior when the parameter is omitted and mentions the 'integrate' topic, but it does not add substantial meaning beyond what the schema already provides.

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 clearly identifies the tool as reading sections of the public Bitbybit integration guide and specifies the exact topics covered, such as browser, server, backend, and CAD Cloud. It also explains the no-topic behavior of listing sections, making the resource and action distinct from sibling tools like get_examples or search.

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?

The description provides concrete usage guidance: it tells the agent to read the "integrate" section before recommending where geometry should run, and clarifies the default versus CAD Cloud decision. It does not explicitly name alternative tools or when not to use it, but the context is clear enough for correct selection.

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