Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
usersYesComma-separated list of user IDs to fetch Do Not Disturb status for (e.g. ``U0123,U0456``).
team_idNoEncoded team ID the users belong to, required for org-wide tokens (e.g. ``T0123``).

Behavior2/5

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

No annotations provided. The description only states 'Retrieve', implying read-only, but does not explicitly explain side effects, authentication needs, or return behavior. Lacks detail beyond the core action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence effectively conveys the tool's purpose without unnecessary words. Appropriate length for a simple retrieval tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that an output schema exists, return values are covered. However, the description does not mention the ability to handle multiple users or team scope, which is relevant for selection. Adequate but not comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents both parameters. The description adds no additional meaning beyond the schema. Baseline 3 is appropriate as schema handles explanation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description specifies the verb 'Retrieve' and resource 'Do Not Disturb status for users on a team', clearly indicating what the tool does. It implicitly distinguishes from dnd_info (single user) and team_info (team details) through context, though not explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like dnd_info or team_info. The description does not mention prerequisites, permissions, or scenarios where this tool is preferred.

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