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

The description correctly indicates mutation and partial updates via 'All body fields optional'. Annotations already declare idempotentHint=true and openWorldHint=true, and the description is consistent with them, adding useful context beyond 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 a single, front-loaded sentence with no unnecessary words. It efficiently conveys the core purpose and a key usage note.

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?

Given the high schema coverage, the presence of annotations, and the straightforward nature of an update tool, the description is adequate. It could optionally mention return values, but the context signals (no output schema) reduce that burden.

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 100%, with each parameter described. The description adds no new semantic details beyond stating that body fields are optional, which is already implied by the schema (only 'id' and 'product_attachment_id' are required).

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 action ('Update') and the resource ('a line-item product attached to a deal'). It distinguishes from sibling tools like 'add' and 'list' versions.

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 'All body fields optional' effectively communicates that only desired fields need be sent for partial updates. However, it does not explicitly mention when to use this tool versus alternatives like 'pipedrive_add_deal_product'.

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