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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered by structured data. The description adds value by naming the returned content areas, which is real behavioral context. It stops short of anything an agent would want on failure modes, whether pricing is live or cached, or whether the payload is expensive — reasonable given the read-only annotation, but not rich.

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 with the verb first and no filler. Every clause (power, amenities, safety features, pricing) earns its place by telling the agent what the response contains, which matters given there is no output schema.

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 one-param read tool with no output schema, the description does the minimum necessary: it names the fields the agent will receive. It omits the relationship to sibling listing/search tools and any note about id provenance, so the agent could still reach for the wrong tool or not know where the id comes from.

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?

Only one parameter exists and schema description coverage is 100% ('Space ID'), so the schema already carries the parameter burden and the baseline is 3. The description adds no format, source, or lookup hints for the id (e.g., whether it comes from search_spaces results).

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 gives a specific verb+resource (get detailed information about a hosting space) and enumerates the facets returned: power, amenities, safety features, pricing. That is well beyond a tautology. It does not, however, distinguish itself from close siblings like search_spaces, match_spaces, or get_space_bookings, which is the only thing keeping it from 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 when-to-use guidance and no named alternative. With search_spaces, match_spaces, and get_space_bookings in the sibling list, an agent has to infer that this tool is the single-record detail lookup keyed by id. The single-required-param schema hints at that, but the description itself offers no explicit routing.

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