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

The description states a read-only 'Get' operation, but annotations declare readOnlyHint=false and destructiveHint=true. This is a direct contradiction, so the description misleads about the tool's behavior. No additional behavioral context is provided.

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 sentence that earns its place, no redundancy.

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?

The tool has no output schema, and the description doesn't state the return format, units, or calculation details. The annotation contradiction further undermines contextual clarity, making it insufficient for an agent to fully understand consequences.

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 schema already documents both parameters (address and resource) with descriptions. The description adds the semantic connection that the resource is energy or bandwidth, but does not add format or syntax details, so baseline 3 applies given 100% 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 clearly identifies a specific verb 'Get' and a resource 'maximum amount of energy or bandwidth an account can still delegate', differentiating it from siblings like delegate_resource (which performs delegation) and get_delegated_resources (which lists existing delegations).

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 phrase 'can still delegate' implies this is for checking remaining delegatable capacity before delegating, which is clear context. However, it does not explicitly name alternatives or state when not to use it, so a 4 rather than 5.

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