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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully structured. The description adds nothing beyond restating the HTTP route — no note on what happens for missing/unknown IDs, no pagination or error behavior.

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?

Extremely short and front-loaded with zero waste, but the terseness crosses into under-specification — the endpoint path is redundant given the tool name and schema.

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?

No output schema exists, so the description carries the burden of describing return shape, yet it says only "one case record." For a single-resource fetch this leaves the agent guessing about the fields returned, without annotations or output schema to fill the gap.

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 coverage is 100% and the case_id property fully documents the UUID format and pattern, so the description is not required to explain parameters. Baseline 3 applies; the description adds no extra semantics.

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?

"One case record" plus the raw endpoint GET /cases/{id}/ conveys a single-record fetch, and the singular distinguishes it from cogmento_list_cases. But there is no explicit verb and no statement of what a case is, leaving purpose implied rather than stated.

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 on when to use this versus cogmento_list_cases or cogmento_create_case, and no prerequisites mentioned. The only hint is the singular/plural contrast in the name itself.

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