wafeq_purchase_orders_partial_update

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

Annotations already indicate this is a write operation with idempotent behavior and no destructive effect. The description adds the HTTP method PATCH and notes it updates data, which is consistent but not a substantial addition 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 short, front-loaded with the action and endpoint, and avoids unnecessary fluff. There is slight redundancy between 'Partial update purchase order' and 'Endpoint for partially updating an existing purchase order', but overall it is appropriately sized.

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?

The schema and annotations carry most of the load for parameters, safety, and idempotency behavior. However, with no output schema and no explanation of return values or update semantics, the description is adequate but not fully complete for nuanced tool selection.

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 description itself does not explain parameters, but the schema covers 67% of parameters with detailed descriptions for body fields and idempotency_key. The id parameter is self-evident from the path, and body fields are well-documented in the schema, so the description adds little but is not required to compensate heavily.

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 identifies the operation as a partial update of an existing purchase order via PATCH. It is specific about the verb and resource, though it does not explicitly distinguish itself from sibling wafeq_purchase_orders_update beyond the word 'partial'.

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 this tool should be used when partially updating an existing purchase order, but it does not explicitly explain when to prefer it over the full update tool or mention any exclusions. It gives clear context but no direct alternative guidance.

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