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 only the raw HTTP route, with no information on what happens when the id does not exist (404/empty), whether related sub-resources are included, or any response shape hints.

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 zero redundancy. It is efficient, though the first sentence is vague enough that its brevity costs clarity rather than earning it.

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 single-record read with full schema coverage and a readOnly annotation, the definition is minimally sufficient to call the tool. It still leaves the agent guessing about not-found behavior and how it relates to the list_notes 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 100%: the single id parameter is fully documented as a UUID GUID obtained from a preceding read, including a pattern. The description adds nothing beyond that, so the baseline 3 for high schema coverage 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?

The verb 'Read' plus the endpoint path 'GET /v1/notes/{id}' implies fetching a single note, but the description says 'the selected record' rather than naming a note explicitly. It never distinguishes itself from siblings like servicemonster_list_notes or servicemonster_get_account, so an agent must infer the resource from the tool name.

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 servicemonster_list_notes or servicemonster_list_account_notes, and no mention that an id must first be obtained from a list call. Usage is only implied by the endpoint path.

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