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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds useful context that results contain PHI and what the note body looks like, but omits pagination behavior and the 'last change' filter it mentions has no corresponding parameter in the schema.

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?

Three dense sentences, front-loaded with the core purpose and returned fields before the filter note and endpoint detail. Slight redundancy with the title's 'List a patient's visit notes' phrasing, but no wasted sentences.

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 an 8-parameter read tool with no output schema, the description usefully summarizes the returned payload (dates, physician, signed state, structured note body) and the PHI nature of the data. Pagination options (limit/cursor/offset) are left entirely to the schema, which is acceptable but a minor gap.

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 all eight parameters are already documented in the schema; baseline 3 applies. The description's date-filter mention roughly mirrors from_signed_date/to_signed_date but adds no syntax, defaults, or constraints beyond the schema, and the 'last change' reference maps to nothing.

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 a specific verb and resource (list one patient's visit notes) and enumerates the returned fields (visit date, type, physician, signed state, note body). It implicitly distinguishes itself from elationhealth_get_visit_note and elationhealth_list_non_visit_notes by scoping to one patient's visit notes, but never names those siblings 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?

It states that results can be filtered by signed date or last change, which hints at usage, but gives no explicit when-to-use guidance or contrast against get_visit_note (single note) or list_non_visit_notes. Usage is implied rather than directed.

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