exclusions_retrieve_an_exclusion

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

The description includes 'READ-ONLY' and 'Makes no changes', which aligns with annotations (readOnlyHint=true, destructiveHint=false). Annotations already declare safety, so the description adds minor context (HTTP method) but does not disclose rate limits or other behavioral traits.

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 very concise (3 lines), with the READ-ONLY badge and endpoint upfront. Every sentence adds value, but it could briefly mention that this retrieves a specific exclusion by ID to improve clarity without adding verbosity.

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 is simple with one parameter, annotations, and no output schema. The description minimally covers the operation but does not explain what an exclusion is or what the response contains, which might be helpful for an agent with no prior context.

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 has 100% coverage with a single parameter 'id' described as 'ID of the exclusion to retrieve'. The description does not add any additional meaning or format hint beyond the schema, so it scores baseline 3.

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 'Retrieve an exclusion' and 'Fetches data', indicating the action and resource. The name includes 'retrieve_an_exclusion', reinforcing the purpose. However, it does not explicitly differentiate from the sibling tool 'exclusions_retrieve_a_list', which retrieves a list of exclusions.

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?

No guidance is provided on when to use this tool versus alternatives like 'exclusions_retrieve_a_list' or 'update_an_exclusion'. There is no mention of prerequisites or scenarios where this tool is appropriate.

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