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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is covered structurally. The description adds a governance note about configurable MCP approval requirements and always-on business workflow approvals, but that note is ambiguous for a read tool and does not describe what the read actually returns or how it relates to the CR's state.

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?

Three sentences, but the actual purpose is buried in the second while the first is generic boilerplate. The third sentence on approval-requirement configuration is of questionable relevance to a read operation, so some text does not earn its place.

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?

An output schema and full annotations remove the need to explain return values and safety, which helps. But for a one-param filtered read, the description leaves the parameter meaning and its relation to sibling approval tools unexplained, so it is only minimally complete.

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 0% and the single required changeRequestId (uuid) has no schema description. The description never mentions the parameter or clarifies that the ID selects which change request's approvals are returned, so it fails to compensate for the coverage gap.

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 second sentence 'Read change-request approvals' states a clear verb plus resource, and the name/title align. However, the lead sentence frames it as 'working with RetailHardHat change_requests records', which is slightly off-target (this reads approvals of a CR, not the CR itself), and it never explicitly distinguishes itself from siblings like get_approval_status, list_pending_approval_requests, or list_change_requests.

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?

'Use this when working with RetailHardHat change_requests records' is boilerplate context, not guidance about when to choose this over alternatives such as list_pending_approval_requests or get_approval_status. No when-not conditions or prerequisites are given.

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