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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely new behavioral context: it spells out the two permission modes (immediate vs return-for-agreement), that limits and remaining-today quota are reported, and that WaitApp connection status is included.

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, front-loaded sentence that moves from the core meaning (what the person allowed) to the mechanics (immediate vs confirm) to the extras (limits, remaining, WaitApp). It is dense and slightly run-on with stacked parentheticals, but no sentence 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?

With no output schema, the description carries the burden of describing the return values, and it does so adequately: permission mode, limits, remaining allowance today, and account connectivity. It stops short of specifying field names or structure, but an agent has enough to know what the call yields and when it is relevant.

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 schema coverage is complete by definition and no parameter explanation is required. Baseline 4 applies; the description adds nothing here but nothing is missing either.

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 identifies this as a read of the connection's authorization state — what the person allowed this connection to do, plus limits, remaining quota, and WaitApp account linkage. It is unmistakably distinct from the booking/ordering siblings since it performs no action itself. It never states a crisp verb+resource ('get permissions'), phrasing the purpose as content instead, which keeps it just below a 5.

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 explicit when-to-use statement or named alternative. The description implies the value of calling it (knowing whether orders go through immediately or need confirmation) which lets an agent infer it should be checked before placing or confirming orders, but this is left to inference rather than stated.

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