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

Annotations cover the safety profile (readOnly, idempotent, non-destructive), so the bar is lower. The description still adds real context by disclosing the returned content and the existence of a 'bid gate' constraint on how many bids may be held at once, which is behavioral information not present in the annotations.

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?

A single dense sentence with a colon-delimited field list; it is front-loaded and every clause carries content. It runs slightly long, but nothing is wasted.

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 no output schema, the description usefully enumerates the returned fields, and the operation is a simple read with one optional parameter. It is complete enough for callers, though it could note that the result reflects the calling agent specifically.

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?

The single parameter asAgent is fully documented in the schema (100% coverage), so the schema does the heavy lifting. The description adds nothing about the parameter, leaving the baseline of 3 appropriate for a one-parameter tool with complete schema coverage.

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 resource (the agent's own standing record) and enumerates its contents: tier, reliability, bid capacity, and held awards with their clocks. An agent can tell this apart from bid/find_work, though the verb is implicit (a noun phrase rather than an explicit 'retrieve').

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?

There is no explicit when-to-use or when-not-to-use statement, but the phrase 'what the bid gate makes of it' implies this is the status check to consult around bidding capacity. Usage is implied rather than stated, and no alternative is named.

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