wafeq_manual_journals_partial_update

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

Annotations already convey that this is a mutating, non-destructive, idempotent write operation. The description adds the 'partial update' semantics, which is useful, and the PATCH endpoint reinforces that only provided fields are updated. However, it does not add deeper behavioral context such as authentication requirements, validation behavior, or effects on existing line items.

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-loads the HTTP method and resource, but it is redundant: 'Partial update manual journal' and 'Endpoint for partially updating an existing manual journal' say essentially the same thing. The repetition makes it less efficient than it could be.

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 partial-update tool with a nested body schema and no output schema, the description is too thin. It does not explain that omitted fields remain unchanged, which fields are commonly updated, how idempotency works in practice, or anything about the response. An agent would have to infer most operational context from the schema and annotations.

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 only 67%, and the description itself says nothing about parameters. The schema does describe the body fields and idempotency_key well, but the required path parameter 'id' has no description and the tool description does not compensate for that gap.

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 verb ('partially updating'), the resource ('manual journal'), and includes the HTTP endpoint 'PATCH /manual-journals/{id}/'. It is easy to tell this is the partial-update variant, though it does not explicitly contrast with the full update sibling wafeq_manual_journals_update.

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 phrase 'Endpoint for partially updating an existing manual journal' implies when to use the tool, but it does not explicitly say when to prefer this over wafeq_manual_journals_update or wafeq_manual_journals_destroy. No exclusions or decision guidance is provided.

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