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

Annotations already flag the operation as destructive and non-idempotent; the description adds crucial process context: no change occurs until a human approves the exact request and execute_approved_action is called, and business workflow approvals always apply. It still doesn't explain whether the update merges or replaces fields, so 4 rather than 5.

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?

Four sentences, front-loaded with purpose and followed by the material approval constraint; little is wasted. The opening 'when working with RetailHardHat rfps records' is generic but not harmful.

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 destructive, approval-gated update with a complex nested data object and no schema field descriptions, the description omits the information an agent most needs: which fields are actually allowed and how to populate data. Output schema coverage means return values need not be explained, but invocation guidance remains incomplete.

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 description does not explain the id or data parameters. 'Update allowed fields' hints that only a subset of fields is mutable, but it never enumerates those fields or clarifies the shape/meaning of the nested data object, so it barely compensates for the schema 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 description names a specific verb, 'Update', and resource, 'rfp', and scopes it to RetailHardHat rfps records in the connected organization. It does not distinguish this tool from siblings such as update_rfp_document or create_rfp, which keeps it from a 5.

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?

It offers a broad 'Use this when working with RetailHardHat rfps records' condition and states the approval prerequisite, but it never contrasts this with create_rfp, list_rfps, or update_rfp_document. The when-to-use guidance is therefore implied rather than explicit.

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