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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered elsewhere. The description adds that the response concerns origin health plus collection volume, but does not explain what 'health' means (availability? latency? freshness?) and there is no output schema to fill that gap.

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 compact sentence with no redundancy, and the resource is placed first. It is arguably over-terse rather than padded, so no waste occurs, but the brevity trades away needed detail.

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-param, annotation-covered tool the remaining burden is explaining the return value, and with no output schema the description should do more than 'health of the origin'. It hints at the contents (origin status, collection size) but leaves the shape and interpretation of the result undefined.

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 tool takes zero parameters, so the schema carries no semantics to document and there is nothing for the description to disambiguate. Baseline 4 applies for a parameterless definition.

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 states a resource ('health of the origin and size of the collection') and adds scope detail ('procurements and documents with text'), which helps distinguish it from data-fetching siblings. However, there is no verb and 'origin' is ambiguous — it does not say whether this checks an upstream source, a connector, or the dataset overall.

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?

No indication of when to call this (diagnostics, preflight check, monitoring) or what to do with the result. No sibling duplicates a health check, so there is no explicit alternative to route to, but the description still provides no usage context at all.

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