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

Annotations already cover read-only, idempotent, open-world, and non-destructive traits. The description adds the useful behavioral trait that results are raw and not synthesized into cluster-health or synchronization claims, which is beyond the annotations. It does not describe response shape, but for a no-parameter status endpoint this is minor.

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 contains the verb, resource, and the critical trust boundary. Every word earns its place and the main action is front-loaded.

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 no-parameter, read-only status tool with rich annotations, the description is nearly complete. The only minor gap is that it doesn't hint at the shape or granularity of returned data, but the raw-endpoint framing plus the non-synthesis caveat gives sufficient context for invocation.

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 schema coverage is complete, so the schema has nothing left to document. The no-parameter baseline of 4 applies; the description doesn't need to add parameter meaning.

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 verb ('Read'), a resource ('live SqueezeOS status endpoint'), and a scope-limiting caveat ('does not synthesize cluster-health or synchronization claims'). This makes the tool's purpose exact and separates it from any capability/x402 siblings that might appear related.

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?

It establishes the intended use: reading live status rather than relying on synthesized health/sync assertions. It doesn't name alternative sibling tools or provide explicit when-not-to-use conditions, but the non-synthesis caveat gives a concrete boundary.

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