wafeq_debit_notes_update

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method and endpoint path, which is useful, but it does not disclose whether this is a full replacement update, what happens to unspecified fields, or how line_items are handled. 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 description is short and front-loaded with method and path, but it contains redundancy: 'updates data', 'Update debit note', and 'updating an existing debit note' all say the same thing. It could be trimmed to a single informative sentence.

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 mutation tool with a complex nested body and no output schema, the description is too thin. It omits response behavior, full-replacement semantics, relationship to partial_update, and any guidance on required body construction. The annotations cover idempotency, but the tool description alone is insufficient for reliable invocation.

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 coverage is 67% and the body schema provides detailed field descriptions, so the parameter meanings are mostly discoverable. The description itself adds little beyond identifying the resource path; it does not clarify the body behavior or the nested line_items semantics beyond the schema.

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 'update', the resource 'debit note', and that it acts on an existing record via 'PUT /debit-notes/{id}/'. It is readily distinguishable from create, retrieve, and destroy tools, though it does not explicitly differentiate itself from the sibling wafeq_debit_notes_partial_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?

There is no guidance on when to use this tool versus alternatives such as partial_update or create. The description only restates that it updates a debit note, leaving the agent to infer context and selection criteria on its own.

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