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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds useful context by naming the underlying GET endpoint and the categories of events returned, but it does not mention pagination, response shape, or rate-limit behavior.

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 plus the endpoint reference, with the resource scope front-loaded and the id-source instruction immediately after. There is no wasted language.

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 read-only, open-world list tool with full schema coverage and clear annotations, the description supplies enough context to invoke it correctly: what window to request, which id to supply, and what event categories are returned. It is only slightly short of complete because it does not describe pagination or result ordering.

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 the baseline would be 3, but the description adds real meaning: 'between two moments' clarifies the start/end role, and the pointer to aryeo_list_team_members explains where the required team_member_id comes from. The enum values are also reflected in the described event categories.

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 states a specific resource and scope: a team member's calendar between two moments, enumerating appointment, block, external, and buffer event types. It is distinguishable from aryeo_list_team_members by pointing there for the id, though it does not explicitly differentiate itself from aryeo_list_appointments.

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 gives one actionable routing instruction: use aryeo_list_team_members to obtain the team_member_id. Beyond that, it implies when to use the tool (to view a calendar window) but gives no explicit when-not guidance or comparison against similar listing tools such as aryeo_list_appointments.

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