wafeq_purchase_orders_retrieve

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description's 'READ-ONLY' and GET wording adds no new behavioral information. It does not disclose permission requirements, error behavior, response shape, or any other context 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 definition is short and front-loads the endpoint and read-only flag, but 'Retrieve purchase order' and 'Endpoint for retrieving a single purchase order' are redundant with each other and with the annotation title. It could be tightened to one sentence 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 one-parameter, read-only fetch, the description plus annotations provide enough to select and call the tool correctly. It lacks explicit response or error expectations, but those are not critical for this simple GET-by-id 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?

The schema only defines a required string 'id', and the description's endpoint path shows it is used as a path placeholder. This adds some context beyond the raw schema, but the description does not explain the id's format or confirm its meaning beyond what the resource name and schema imply.

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 a specific verb and resource ('Retrieve purchase order') and explicitly narrows the scope to 'a single purchase order', with the endpoint path showing GET /purchase-orders/{id}/. This distinguishes it from list, update, and destroy siblings even without naming them.

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 implies the tool is for fetching one purchase order by ID, but it gives no explicit when-to-use or when-not-to-use guidance and names no alternatives such as wafeq_purchase_orders_list. An agent must infer the intended use from 'single purchase order' and the {id} path placeholder.

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