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

The annotations indicate the tool is not read-only and not destructive, which is inherently present in the description's 'open' action. The description adds no further behavioral detail such as whether suppliers are notified, whether budget is reserved, or whether the request is reversible.

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 concise but under-specified; it is a minimal label rather than a helpful tool description. There is no fluff, but the lack of essential semantic content makes it inappropriate size for a tool with six parameters.

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?

There is no output schema, no parameter documentation, no usage guidance, and no return or side-effect information. The description leaves nearly every invocation detail unknown, making successful tool use unlikely without additional external knowledge.

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?

With schema description coverage at 0% and six parameters, the description must compensate by explaining parameter roles, but it mentions none. An agent has no idea what 'capability', 'goal', 'mode', 'currency', 'max_bids', or 'budget_cents' mean or how to set them.

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 uses a recognizable verb ('open') and names a clear resource ('supplier bid request'), so an agent can tell it starts some kind of bid request. However, 'open' is vague compared to the tool's name 'create_bid_request', and there is no explicit differentiation from siblings like submit_bid or propose_for_request.

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 is provided about when to use this tool versus alternatives such as post_request, propose_for_request, or create_buyer_goal. The description is only a single action phrase with no prerequisites, exclusions, or context about the bidding workflow.

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