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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds meaningful context beyond that by enumerating the returned state values (active, error, expired) and the diagnostic fields (connected account, last error), which is useful in the absence of an output schema; it does not, however, say whether all integrations or a single one are returned.

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 filler, and the resource is front-loaded ahead of the enumerated fields. It is a fragment rather than a full sentence, but nothing is wasted.

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-argument, read-only tool with no output schema, the description does the necessary work of sketching the return payload (status values, connected account, last error). The only gap is whether the result covers one integration or all of them and in what form.

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 per the rubric the baseline is 4. There are no parameter semantics to explain and the description correctly spends no effort on them.

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 resource (the workspace's accounting/business integrations) and enumerates what is reported: status, connected account, last error. It lacks an explicit verb (it reads as a noun phrase), but an agent can still tell what it retrieves and it is distinguishable from data-oriented siblings like list_ai_connections or activity_summary.

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?

There is no guidance on when to call this versus alternatives, no prerequisites, and no mention of any sibling tool. The agent must infer the trigger condition (wanting to check integration health) entirely on its own.

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