GET /departments/{id}

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is fully covered. The description adds nothing beyond the route – no note on what is returned, whether missing departments error out, or any auth/pagination context.

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?

It is short and front-loaded, but the second sentence ('Generated from Snipe-IT OpenAPI operation departmentsid.') is boilerplate that adds no information about behavior or usage.

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 single-GET read tool with annotations covering safety and only one integer parameter, this is minimally adequate. Still, no return-shape hint is given despite there being no output schema, so an agent cannot anticipate what a department object contains.

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 single parameter 'id' has 0% schema description coverage, so the description should explain that it is the department ID and perhaps what form it takes. It says nothing about the parameter at all.

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 states a specific verb and resource ('View a department') and mirrors the route, so the basic purpose is clear. However, it offers no differentiation from close siblings like snipeit_gen_departmentsid_1, _2 and snipeit_gen_departments_edit, leaving the agent unsure which department endpoint to pick.

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?

There is no when-to-use guidance, no mention of when to prefer this over the duplicate departmentsid siblings or snipeit_raw_request, and no prerequisites. Usage is only implied by the route string.

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