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 real behavioral value by disclosing pagination behavior ('Returns a page plus next/previous') and the underlying DrChrono endpoint, which matters since there is no output schema. It does not mention auth or rate limits, but the pagination disclosure is a meaningful addition.

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 tight sentences front-load the purpose and filters, followed by the return shape and endpoint. Every clause earns its place with no redundancy.

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-required, 100%-documented filter tool with no output schema, the description supplies the missing pagination contract and endpoint. It omits nothing an agent needs to call it correctly, though return-field detail is necessarily absent.

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%, so all six parameters including format patterns and defaults are fully documented in the schema. The description's filter list mirrors the params without adding syntax or format detail, so the baseline 3 applies.

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 (clinical notes) and enumerates the filter dimensions, which distinguishes it from the many sibling list tools by resource alone. An agent can identify the tool's function without opening the schema.

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 filter list implies when this tool is appropriate (retrieving notes scoped to a patient/date), but there is no explicit when-to-use vs alternatives or exclusion guidance. Usage must be inferred from the filter enumeration.

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