wafeq_items_partial_update

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the write nature is established. The description adds the partial-update behavior and that the item must already exist, which is useful, but it does not disclose response behavior, side effects, or update-specific details beyond what annotations and schema already provide.

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 compact and front-loaded with the endpoint and write label. The second sentence ('Endpoint for partially updating an existing item') largely repeats the first, a minor redundancy that keeps it from a 5.

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 and the payload is complex and nested, yet the description gives no indication of the response shape, which fields are required versus optional, or practical usage guidance. An agent could call it from the schema, but the description alone leaves too much unsaid for a mutation tool with this complexity.

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 already provides detailed descriptions for the body fields and the idempotency_key, and the description adds the essential partial-update semantic that omitted fields remain unchanged. However, the id parameter itself has no description, and the body description is oddly serializer-focused rather than explaining the payload's purpose.

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 tool as a partial update for Items, gives the HTTP method and path (PATCH /items/{id}/), and the 'partial' modifier distinguishes it from wafeq_items_update. The resource and action are unmistakable.

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 partial-update semantics imply when to use it, but there is no explicit guidance about when to choose this over wafeq_items_update or when only some fields should be supplied. The intended usage is clear only by inference from the name and the word 'partial'.

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