bulk_update_deal_owners

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

Description states 'Modifies an existing record in place. Idempotent.' which aligns with annotations (idempotentHint: true, destructiveHint: false). It also provides the HTTP method and endpoint (PATCH /deals/bulkUpdate), adding value beyond annotations. No contradictions.

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 but includes non-essential formatting (emoji, bold) and repeats 'Update an existing deal' after already stating the purpose. It could be cleaner by focusing on key information without decorative elements.

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?

With annotations and schema covering safety and parameters, the description adds endpoint and idempotent note. However, it lacks mention of return values or expected response. Given no output schema, the description could be more complete by describing what the response looks like.

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 100%, so parameters are fully documented in the schema. The description does not add any additional meaning or usage hints beyond what the schema provides (e.g., that id is required, ownerId format). Adequate but no extra value.

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 'Bulk Update Deal Owners' and 'Update an existing deal', specifying the action and resource. It distinguishes from sibling tools like 'update_a_deal_new' by emphasizing bulk operation. However, it could be more precise about the scope (e.g., only updating ownerId, not other fields).

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?

No guidance on when to use this tool versus alternatives. Sibling tools include individual deal updates and other bulk updates, but the description does not provide criteria for choosing this tool. No exclusions or prerequisites mentioned.

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