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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld). The description adds a return-content hint ('their text and date'), but says nothing about ordering, pagination behaviour or what happens with an invalid subject id.

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?

One front-loaded sentence that gets to the point quickly. Minor filler in 'and more' and the trailing 'Teamleader: notes.list.' API mapping, which an agent gains little from.

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?

A simple read-only list tool with full schema coverage, complete annotations, and a return-content hint that substitutes for the missing output schema. The only real gap is that the description doesn't clarify that exactly one subject type/id pair is queried per call.

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 page, page_size, subject_id and subject_type are all documented in the schema. The description only loosely restates the subject types already enumerated and adds nothing about page/page_size semantics; 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 (notes) plus the set of attachable subjects, so an agent can tell it apart from teamleader_add_note. It does not explicitly name the write-side alternative, but the read/list framing 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?

No statement of when to use this versus alternatives, no prerequisites (e.g. needing a valid subject id), no note about paging through results. Only implied usage from the resource list.

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