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

The annotations already declare readOnlyHint=true, and the description's 'Status of...' wording is consistent with a read-only operation, so there is no contradiction. The description adds useful context that only signed-in business owners can use it and lists the status contents. However, it does not disclose response shape, what happens without business_id, or how pending requests are defined.

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 two short sentences with no filler, and the eligibility qualifier is front-loaded. Every phrase contributes either scope or content information. It is concise, though the second sentence is a noun-phrase list rather than a crisp verb-led statement.

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 simple read-only status tool with one optional parameter and no output schema, the description covers the key data categories and the owner-only restriction. It does not explain exact return formatting or edge cases like multiple businesses, but the schema covers the parameter and the annotations cover the safety profile. This is adequate but not exhaustive.

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?

Schema description coverage is 100%: the only parameter, business_id, is documented as 'Only needed if you manage several businesses.' The tool description itself adds no parameter-level detail, so it stays at the baseline 3 for fully schema-covered parameters.

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 states that the tool surfaces the status of a signed-in business owner's businesses and applications, including pending requests count and unfinished draft. It is easy to identify as a read-only status/dashboard tool. However, it lacks an explicit verb like 'Gets' or 'Returns,' and it does not distinguish itself from related siblings such as op_businesses or op_applications.

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 only usage guidance is the eligibility qualifier 'Only for business owners signed in to Awning,' which implies non-owners should not use it. It does not explain when to prefer this tool over related owner tools or what scenario would route an agent here. This is implied context rather than explicit alternative selection guidance.

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