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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so 'No write' and the REST verb add nothing. The genuinely useful additions are the scope constraints ('Default Spaces are log / L2; articles writes are unavailable'), which describe the Seat's limits rather than this tool's behavior, and the 'REST GET /v1/seat' pointer, which is implementation detail. Behavior on the no-bound-Seat case is undisclosed.

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?

Front-loading the returned fields is the right call, and the whole thing is four short clauses. The 'No write' clause repeats readOnlyHint and the raw endpoint string earns little space, but the overall size is appropriate.

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 enumeration of returned fields carries real weight and is present. Annotations cover the safety profile, so nothing critical is missing; only the no-seat-bound outcome and the shape/format of the returned identifiers are left implicit.

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 baseline applies and there is no parameter semantics to add. The description correctly avoids inventing or discussing inputs.

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 first sentence names a specific verb ('Return') and resource (the bound Seat) and enumerates exactly what is returned: identifiers, name, live scope, maturity_level, capabilities, active status. It also tells the agent how this differs from list_seats, so selection is possible without opening either schema.

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?

It explicitly routes the agent to list_seats when every seat in the Space is wanted, which is a concrete alternative with a selecting condition. What it does not cover is the ambiguous case: whether this errors or returns empty when no Seat is bound, and whether any precondition exists for calling it.

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