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

With no annotations, the description must carry the full behavioral disclosure. It adds two pieces: that admin approval is required and that credentials should never be submitted. It does not disclose side effects (e.g., whether it creates a persistent offer), whether it is a write operation, what triggers success/failure, or any reversibility. For a mutation-like tool, this is minimal and insufficient.

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 extremely concise, with two sentences that front-load the core purpose and follow with a security warning. Every word serves a purpose; there is no fluff or redundancy. It is appropriately sized for the information it conveys, even though that information is incomplete.

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 tool with 8 required parameters, no output schema, and no annotations, the description is severely under-specified. It omits any explanation of what the offer entails, how to fill parameters, what the response looks like, failure conditions, or how the admin approval process works. An agent cannot confidently invoke this tool correctly based on the given description.

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 only 13% (only expires_at has a description), so the description must compensate. It hints at 'no_charge' via 'at no charge' and 'operator_authorized' via 'operator-authorized', but does not explain the meaning of 'capacity', 'workloads', 'client_id', 'title', or 'details'. The agent is left without guidance on these required parameters, which is a significant 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 clearly states the verb 'Offer' and the resource 'your operator-authorized capacity', and specifies 'at no charge'. This conveys the primary action and distinguishes it from request-oriented siblings like request_compute. However, it does not explicitly name alternative tools or elaborate on the outcome of the offer.

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 description mentions 'administration approval required', giving a precondition for use, and warns 'Never submit credentials', a security guideline. It does not explicitly state when to use this tool versus alternatives (e.g., request_compute, withdraw_compute), leaving the decision partly to inference. The context of offering capacity is implied but not contrasted with sibling tools.

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