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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds the substantive content of the policy (what the assistant will NOT do: screening, attestations, payment, care decisions), which is genuinely useful behavioral context beyond the annotations, but it doesn't describe return format or open-world implications despite openWorldHint=true.

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 sentences, no filler, reasonably front-loaded. However, the first sentence conflates two concepts ('connector limits' and 'website handoff policy') with the title's stated purpose ('no-form-filling policy'), creating a structural mismatch rather than clarity.

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 zero-parameter read-only policy tool with full annotation coverage and no output schema, the description is minimally adequate. It conveys the topic but leaves the concrete content of the policy and its relationship to the sibling boundary tools underspecified.

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?

There are zero parameters, so the baseline is 4. The description adds no parameter information and none is needed, since the schema is a closed empty object.

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 states the resource ('public connector limits and website handoff policy') but the verb framing is weak: the title says 'no-form-filling policy' while the description describes 'connector limits and website handoff policy', which is a different framing. An agent can grasp it's a policy-reader, but the exact scope is ambiguous against siblings like get_online_care_boundaries and get_service_details.

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 second sentence implies a context (practice website responsibilities) but never tells the agent when to call this versus get_online_care_boundaries or explain_visit. Usage is implied by the content rather than stated as an explicit trigger.

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