Read one category

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

The description adds an auth requirement ('Needs a key carrying the taxonomy:read scope') that is not present in annotations. It also reinforces the read-only and non-destructive nature, consistent with annotations, without contradicting them.

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 concise with three short sentences, each adding value: purpose, safety, and auth requirement. It is front-loaded and free of filler, earning a high score.

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?

Given the tool's simplicity (single parameter, no output schema), the annotations cover safety, and the schema covers parameters, the description is nearly complete. The auth scope adds useful contextual detail. It does not describe return format, but that is not critical for a simple getter.

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 input schema fully covers the only parameter 'id' with a description of 'A UUID', achieving 100% coverage. The description does not add extra meaning beyond the schema, so baseline 3 is appropriate.

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 the tool reads one category, using a specific verb and resource. It distinguishes from sibling tools like list_categories, create_category, update_category, and delete_category by indicating a single read operation.

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 implies usage for retrieving a specific category by ID but does not explicitly mention alternatives such as list_categories for multiple categories or exclude write operations. The read-only context is clear, but no direct when-not-to-use guidance is given.

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