get_summaries

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

No annotations are provided, so the description must disclose behavioral traits. It only states it fetches compact summaries, but does not explain what a 'compact summary' includes, how invalid titles are handled, or if results are ordered. Minimal transparency beyond basic purpose.

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 a single sentence of 10 words, with no unnecessary information. It is maximally concise while still being clear.

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 tool has an output schema, so return values may be documented elsewhere, but the description fails to mention behavioral details like error handling, the nature of summaries, or constraints. Given the lack of annotations, the description is incomplete for a useful tool.

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 description coverage is 0%, so the description must add meaning. The description clarifies that 'titles' are Wikipedia page titles and that multiple can be provided. However, it doesn't add details about formatting (e.g., exact title matching) or limits. Provides moderate value over the raw schema.

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 states that the tool fetches compact summaries for one or more Wikipedia page titles. The verb 'fetch' and resource 'compact summaries' are specific, and it distinguishes itself from siblings like 'get_page' (full page) and 'search_articles' (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 does not provide explicit guidance on when to use this tool versus alternatives. While the name and sibling list imply it is for summaries, there is no mention of when to prefer it over 'get_page' or 'get_section'.

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