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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds that this is a GET endpoint and mentions optional location scoping, but says nothing about pagination, ordering, or volume of results for a list operation. Adding the HTTP method is minor value over the annotation.

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?

Two short sentences, front-loaded with the resource and its meaning, then the endpoint. No waste, though the trailing 'GET /operatories' adds little for an agent that already sees the tool name.

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 read-only list tool with no output schema and fully documented parameters, the description covers the essentials. It could mention result shape or pagination, but nothing critical to correct invocation is missing.

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 100%, so both subdomain (with its NEXHEALTH_SUBDOMAIN default) and location_id are fully documented in the schema. The description adds only 'optionally scoped to a location,' which restates the schema. Baseline 3 is appropriate.

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 specific verb (List) and resource (operatories), and clarifies with '(chairs/rooms)' that operatories are physical rooms, which is helpful domain context. It doesn't explicitly distinguish itself from sibling list tools like nexhealth_list_locations, but the resource is unambiguous.

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 'optionally scoped to a location' implies the two usage modes (all operatories vs. one location's), but there is no explicit when-to-use guidance, prerequisites, or reference to alternatives. Usage is only weakly implied.

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