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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered structurally. The description adds two genuinely useful traits beyond that: a cap of 100 and newest-first ordering. However, it does not disclose whether the cap is silent truncation or whether any paging mechanism exists, which is the main behavioral risk for a capped list.

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?

A single front-loaded sentence with no filler, stating the resource, cap, and ordering in one pass. It is efficient, though the extreme terseness is what leaves the pagination behavior unaddressed.

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 two-parameter read-only list operation with no output schema, the description covers scope, ordering, and count. Gaps remain around what a note object contains and what happens when a role has more than 100 notes, both of which the agent would need absent an output schema.

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 50%, with workspaceId fully documented inline (including the 'personal' sentinel and a pointer to list_workspaces). roleId is undocumented but self-explanatory as a UUID identifier for the role, so the description needs little compensation. The description adds no semantics beyond the schema.

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 and resource combination (list notes on a role) that is unmistakable against siblings like add_role_note or list_role_stages. It does not explicitly name the write counterpart or distinguish itself from it, but the read framing is clear.

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 explicit guidance on when to use this versus alternatives, and no prerequisites stated. The implicit use case (retrieve notes for a role) is inferable, but the hard limit of 100 with no stated way to page beyond it leaves the agent without guidance on what to do when the cap is hit.

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