Show Company Segment Item

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

Annotations already indicate readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is covered. The description adds that it returns a JSON object and mentions the API endpoint, but does not disclose additional behavioral traits beyond the annotations.

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 four sentences: first states purpose, second gives usage hint, third lists required parameters, fourth provides API details. It is well-structured and front-loaded with the most critical information.

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 simple resource (Company Segment Item) and the presence of annotations and full schema descriptions, the description adequately covers the tool. It notes the return type as a JSON object. The only minor gap is that it does not explain optional parameters like page/per_page, but those are shown in the schema.

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 100%, so the baseline is 3. The description repeats the required parameters (company_id, segment_id, id) but does not add meaning beyond what the schema already provides for individual parameters.

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 'Return details on a specific Company Segment Item' and 'fetch the full details of a specific Work Breakdown Structure records by its identifier.' It uses a specific verb (Return details/fetch) and resource (Company Segment Item / Work Breakdown Structure records), distinguishing it from sibling list/delete tools.

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 explicitly says 'Use this to fetch the full details of a specific Work Breakdown Structure records by its identifier,' providing clear context for when to use this tool. However, it does not explicitly state when not to use it or mention alternative tools for listing, though the sibling 'list_company_segment_items' implies the distinction.

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