get_category

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses what comes back (description text and article count) and 'Fetch' implies a read-only lookup, but it says nothing about behavior for a nonexistent/invalid ID or any access requirements.

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 sentence with zero filler, front-loaded with the verb and the lookup key, and it also compresses the return payload into the same line. Nothing is wasted.

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?

For a simple getter with an output schema present, return-value detail is not strictly required, so the description is nearly sufficient. However, with no annotations and 0% schema coverage, it leaves the response_format parameter and not-found behavior unexplained.

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 compensate. It clarifies that the ID identifies a single category, but the second parameter (response_format) is never mentioned in the description; only the $defs enum definition hints at its meaning.

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?

States a specific verb (Fetch) and resource (a single category by ID), and the 'single ... by ID' scope clearly separates it from the sibling list_categories. It does not name any sibling explicitly, so it lands just short of the top tier.

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 implied: use this when you already have a category ID and need one category rather than a list. There is no explicit when-to-use/when-not guidance, no mention of list_categories as the alternative, and no error/precondition context.

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