pipedrive_update_deal_product

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

Annotations already indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=true, covering basic safety. The description adds no further behavioral context—such as whether unspecified fields are preserved, prerequisites like the need for an existing product_attachment_id, or side effects on other deal fields. It merely restates that it is an update, adding minimal value beyond the 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 sentence with no redundancy, which is good for conciseness. It is front-loaded with the primary action and resource. However, it is so terse that it sacrifices useful context that could be included without bloating the text.

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 complexity (15 parameters) and no output schema, the description is woefully incomplete. It does not explain how to obtain the product_attachment_id, how the update interacts with existing deal product data, or what the response indicates. With no example or additional context, an agent may struggle to correctly use this tool, especially given the large sibling set.

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%, so every parameter is described in the schema. The description's assertion that 'All body fields optional' aligns with the schema's required field list and does not add new meaning. It clarifies that only required fields are id and product_attachment_id, but this is already explicit. No additional parameter-level guidance (e.g., relationships between fields or format nuances) is provided.

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 states a clear verb ('Update') and resource ('a line-item product attached to a deal'), which distinguishes it from add/list operations. However, it does not explicitly differentiate from sibling tools like pipedrive_update_deal or pipedrive_add_deal_product, relying on the resource phrasing to imply the distinction.

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 provides no guidance on when to use this tool versus alternatives such as pipedrive_update_deal or pipedrive_add_deal_product. The only usage hint is 'All body fields optional,' which addresses parameter semantics rather than tool selection. Given 15 siblings with overlapping deal/product functionality, the lack of routing guidance is a significant gap.

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