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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so restating "Read-only, idempotent" earns nothing. The description does add real context: it works with or without a seat, meaning it is safe to call before authentication, and it enumerates the three states it can report back.

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 call condition is front-loaded in the first clause, and every subsequent clause adds information. The parenthetical goal list is a bit of a run-on, but it is dense rather than redundant.

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 return values, and it does so by naming the three location states and the grouping scheme. The "working loop" content is left opaque, which is a minor remaining gap for a zero-parameter entry point.

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 there is nothing for the description to disambiguate and the baseline of 4 applies. Nothing in the text misdescribes the input contract.

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?

States a concrete verb and resource: it returns the caller's current seat/space state, a goal-grouped tool index, and the working loop. That is clearly an orientation/meta tool, which distinguishes it from every sibling in the list that performs actual work.

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?

"Call this first if you are unsure what to do" gives an explicit trigger condition, and the implied converse is that a confident agent should call the specific tool directly. It stops short of naming a concrete alternative or explicitly saying when not to call it.

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