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

Annotations already declare readOnly, idempotent, closed-world behavior, so only content scope needs covering, and the description does list the data categories returned. It does not clarify whether all locations are guaranteed to be returned or how the conversation_id affects behavior.

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 front-loaded sentence that spends its words on the returned content. The closing 'No contact details needed' is slightly cryptic but does not bloat the text.

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?

An output schema and rich annotations mean the description needn't explain return values or safety, and it plausibly covers content scope. However, the unexplained conversation_id and lack of routing guidance leave gaps for an agent choosing among six siblings.

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 description coverage is 0% and the single parameter (conversation_id) is never mentioned in the description, so an agent gets no meaning for it from either source. With no compensation for the coverage gap, this falls below baseline.

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 (CANOPY locations) and enumerates the attributes returned (name, neighborhood, address, hours, memberships, tour booking), making clear this is the all-locations listing. It implicitly contrasts with the singular get_location sibling but never states that contrast explicitly.

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 guidance on when to use this versus get_location, get_membership_options, or ask_sales_question. The trailing 'No contact details needed' is ambiguous and reads more like a note than a usage condition.

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