wafeq_beneficiaries_partial_update

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

Annotations already cover the write, idempotent, non-destructive nature of the tool. The description adds the HTTP PATCH method and the 'existing beneficiary' scoping, but does not go further into side effects, authorization needs, or failure behavior. 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 badge line is compact and informative, but the two prose sentences are redundant: 'Partial update beneficiary' and 'Endpoint for partially updating an existing beneficiary' say essentially the same thing. A tighter description would keep one of them.

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 description is adequate for identifying the tool but minimal for a nested-body mutation operation with no output schema. It does not explain what the response looks like, whether at least one body field should be provided, or how errors surface. The schema compensates for field details, but the overall context remains basic.

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's endpoint path clarifies that `id` is a URL path parameter, which is useful since the schema's id property has no description. The body fields are well documented in the schema, and idempotency_key already has a detailed explanation. The description does not add rich parameter meaning, but the path mapping and schema coverage provide a reasonable baseline.

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 the operation: 'PATCH /beneficiaries/{id}/', 'updates data', and 'partially updating an existing beneficiary'. It specifies the resource (beneficiaries) and the partial-update verb, which distinguishes it from siblings like wafeq_beneficiaries_update and wafeq_beneficiaries_retrieve.

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 says this is for partially updating an existing beneficiary, which gives clear context for when to use it. However, it does not explicitly contrast it with the full update tool, mention when not to use it, or state prerequisites beyond 'existing'.

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