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

Annotations already declare this is a non-read-only, non-idempotent, non-destructive mutation. The description adds genuinely useful behavior beyond that: no change occurs until a human approves in Settings > MCP and execute_approved_action is called, required fields are app-validated, and org admin configures MCP approvals while business workflow approvals always apply. This is strong, non-redundant context.

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 approval-workflow sentences are information-dense and front-loaded, but 'Create bid.' merely restates the tool name and title, wasting a sentence. Overall compact but with a redundant fragment.

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?

Output schema exists so return values need not be described, and the approval flow is thoroughly explained. But for a nested 19-field payload at 0% schema description coverage, the absence of any parameter guidance leaves a meaningful gap for an agent building the request.

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 nested 'data' object carries 19 undocumented fields (contractor, category, amount, submittedDate, plus many optional UUIDs and money fields). The description only says required fields are validated by the application, providing no field-level meaning, 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?

States a specific verb+resource ('Create bid') and frames it as operating on RetailHardHat bids records in the connected organization, which orients the agent well. It does not explicitly differentiate from siblings like update_bid or list_bids, keeping it just short of 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?

The opening 'Use this when working with RetailHardHat bids records' gives a general usage context, and the approval-notice adds practical when-to-use behavior. However, no explicit when-not-to-use or comparison to alternative tools like update_bid or create_rfp is provided.

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