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 elsewhere. The description adds the content scope (services, coverage areas, bookable offerings), but says nothing about behavior on an unknown brokerage_id or whether the result is a summary versus a full record.

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?

One short sentence, front-loaded with the resource and listing three concrete content categories. Nothing is padded or 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?

For a simple single-parameter read tool with no output schema, the description adequately signals the three kinds of information returned. A brief note on what happens with an invalid id, or a pointer to check_area/open_times for granular queries, would close the remaining gap.

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 coverage is 100% and the single parameter is documented as a brokerage id "as listed by the brokerage search." The description's "chosen brokerage" adds only a weak hint about provenance, so the schema is doing essentially all the work here.

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 the resource (a specific brokerage) and the three content categories returned: services offered, areas served, and bookable items. That is concrete enough to separate it from find_brokerages (search) and book_time (action), though it never explicitly names those siblings.

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 phrase "the chosen brokerage" implies this is a follow-up call after find_brokerages, and the required brokerage_id reinforces that. However, there is no explicit statement of when to prefer this over check_area or open_times, even though "areas it serves" and "what can be booked" overlap with those siblings' territory.

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