wafeq_debit_notes_partial_update

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

Annotations already indicate a write operation (readOnlyHint=false), non-destructive (destructiveHint=false), and idempotent (idempotentHint=true). The description reinforces this with 'WRITE · updates data' and 'PATCH'. It adds no additional behavioral context beyond annotations, such as effects on omitted fields or required preconditions, so it earns only a baseline 3.

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 has redundant statements: 'Partial update debit note' and 'Endpoint for partially updating an existing debit note' convey the same information. The PATCH line is useful, but the duplicate sentences could be collapsed into one concise statement.

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 tool with a large nested body and no output schema, the description is very terse. It does not explain that only provided body fields are changed, nor does it mention that body is optional. The schema and annotations compensate partially, but the key partial-update behavior is left implicit.

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 67%, so the schema already documents most fields. The tool description adds no parameter-level detail; the id and body semantics are left entirely to the schema. Baseline 3 is appropriate.

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: 'Partial update debit note' and 'Endpoint for partially updating an existing debit note.' It specifies the HTTP verb (PATCH) and resource (debit notes), and the word 'partial' distinguishes it from the sibling wafeq_debit_notes_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 description implies this tool is for updating only some fields of a debit note, but it does not explicitly say when to choose it over wafeq_debit_notes_update, nor does it state that omitted fields remain unchanged. The context is present but not spelled out.

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