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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description reinforces this with 'Read'. It adds useful context by specifying the exact status areas covered (providers, caps, zero-upfront). It does not mention rate limits or freshness, but for a simple no-parameter read-only tool this is a minor gap, not a contradiction.

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 one concise sentence, starts with the action verb, and contains no filler. Every word adds meaning, and the key scoping term 'compute' appears immediately.

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 zero-parameter, read-only, annotation-backed tool, the description is essentially complete: it names the resource and the dimensions of status returned. It does not describe the response format, but the absence of an output schema and the simplicity of the tool make this a minor rather than significant omission.

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?

There are zero parameters and the schema coverage is 100%, so the description has no parameter-semantics burden. The domain-specific terms are output-relevant, not input-relevant, and no parameter documentation is missing.

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 clear verb ('Read') with a specific resource ('AgentLot 20.1 compute economy') and enumerates the concrete status components: compute providers, hard caps, and zero-upfront status. This distinguishes it from sibling tools like code_economy_status by scoping to the compute domain.

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 clearly implies this tool is for reading the current state of the AgentLot compute economy. It does not explicitly name alternatives or exclusion conditions, but the read-only, no-parameter status nature makes the invocation context clear enough.

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