wafeq_cost_centers_retrieve

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method (GET) and endpoint path, which is mild extra context, but it discloses no additional behaviors such as auth requirements, error conditions, or response characteristics. No contradiction with 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 short and front-loaded with the useful READ-ONLY/HTTP-method header line, but it is redundant: 'Retrieve cost center' and 'Endpoint for retrieving a single cost center' say essentially the same thing. One of these sentences could be trimmed without losing 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?

For a simple single-retrieve tool with one required parameter and strong safety annotations, the description is nearly complete: it provides the endpoint, the read-only nature, and the single-item scope. It does not describe the return value shape, and there is no output schema to compensate, but the implied response (the cost center object) is predictable for this operation.

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 0%, so the description carries the burden for the single 'id' parameter. The path template GET /cost-centers/{id}/ usefully signals that id is a URL path parameter, which is a small addition beyond the bare schema. However, it does not define the id's format, source, or semantics beyond what the tool name already implies.

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 ('retrieve') and resource ('cost center') with a clear single-item scope ('retrieving a single cost center'), and the GET /cost-centers/{id}/ path reinforces this. It implicitly differentiates from sibling wafeq_cost_centers_list and wafeq_cost_centers_create, though it does not name alternatives explicitly.

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?

Usage context is implied rather than stated: an agent can infer this tool is for fetching one cost center by ID when the ID is already known, versus listing all cost centers. However, there is no explicit when-to-use guidance, no exclusions, and no named alternatives among the many sibling tools.

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