A4/5.0
Behavior4/5

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 useful behavior beyond that: the 3-topic cap and the fact that omitting keys returns the full topic index with keys and URLs. It doesn't mention truncation/paging, but the schema covers maxLength and startIndex.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the primary capability, then the invocation rules. No filler and nothing repeated unnecessarily.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only documentation tool with full schema coverage and no output schema, the description covers what is returned (topic keys/URLs or topic text) and how to select topics. The only mild gap is not hinting at the paginated/nested-topic structure, which the schema handles.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description restates the topic/topics equivalence and the omit-both behavior that the schema already documents, adding only the explicit 'up to 3' cap in prose; it does not clarify what happens if both topic and topics are supplied.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource ('List the Loadster manual's topics') and explicitly states the two modes: metadata listing versus reading up to 3 topics' text. It does not differentiate from documentation-adjacent siblings like get_example or get_scripting_api, keeping it short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Pass one key as topic, or up to 3 keys as topics. Omit both to list every topic' gives clear selection rules for each mode. It stops short of naming alternatives (e.g., when to use get_example instead), so it is a strong 4 rather than a 5.

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