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

No annotations are provided, so the description must cover behavioral traits. It only says 'Cancel' without disclosing effects (e.g., irrevocable, requires the tour to be in a cancellable state, authorization needs). This is insufficient for an agent to understand consequences.

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 short sentence with no fluff, but it is under-specified. Conciseness is good, but the lack of necessary detail prevents a higher score.

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 simple cancel action, the description omits key context: whether cancellation is reversible, if the tour must be in a specific state (e.g., not yet occurred), and what the response looks like. Insufficient for an agent to reliably invoke the tool.

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 single parameter 'tour_id' has no description in the schema (0% coverage). The description adds no meaning about where to obtain the ID, its format, or constraints. Minimal value 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?

The description clearly states the action 'Cancel' and the resource 'a tour request', matching the tool name. It distinguishes from siblings like 'parent_request_tour' (create) and 'daycare_respond_to_tour' (different actor).

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?

The description implies use for tours you previously submitted, but no explicit guidance when to use vs alternatives, nor any exclusions or prerequisites. Given many sibling tools, this is a gap.

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