wafeq_debit_notes_line_items_update

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

The description notes it is a WRITE operation and provides the HTTP method, giving clear mutation intent. Annotations already indicate idempotentHint=true and destructiveHint=false, so the description need not repeat those. However, it does not disclose whether omitted fields are reset or how the API handles conflicts, but for a simple update this is acceptable.

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-loaded with the WRITE action and endpoint. The repeated 'Update debit note line item' line is somewhat redundant with the title, but it does not harm clarity or brevity.

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 nested-object mutation with no output schema, the description is brief but adequate. It lacks information about response format, error conditions, or required relationships, but the schema supplies required fields and the annotations cover idempotency and destructive behavior.

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 50%, and the description adds no parameter explanation beyond what the schema provides. The nested body fields have individual descriptions, but the path parameters (id and debit_note_id) are undocumented. The 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 explicitly states 'Update debit note line item' and includes the endpoint path, so the action and resource are unambiguous. The title and schema align. It does not explicitly differentiate from sibling update tools, but the resource name is specific enough.

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 gives no guidance on when to use this tool versus alternatives like 'partial_update' or 'destroy'. There is no mention of prerequisites, such as needing the debit_note_id and line item id, or when a full update is preferable to a partial update.

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