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

With no annotations, the description must disclose behavioral traits, but it omits whether the tool is read-only, mutating, requires authentication, or has side effects. The agent has zero insight into 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?

The description is short but severely under-specified. Brevity is wasted without essential details; it does not earn its place by being informative.

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?

Given no annotations, a meaningless input schema, and no explanation of output (though an output schema exists), the description is completely inadequate for a tool with many siblings and potential complexity.

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?

The input schema has a single 'kwargs' parameter with no type or description, and schema description coverage is 0%. The description adds no parameter meaning, leaving the agent blind to required inputs.

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 'Find meeting time slots' is vague and barely extends the tool name. It doesn't specify what inputs are needed (e.g., attendees, date ranges) or output format, and fails to distinguish it from sibling tools like 'get_my_availability'.

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 guidance is given on when to use this tool versus alternatives. Sibling tools like 'get_my_availability' and 'list_events' likely overlap, but the description offers no comparative context.

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