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

Annotations provide no safety hints (all false), so the description carries the full burden. It adds useful behavioral context: it does not submit patient data or claim a booking, and the action is expiring and attributed. However, it does not disclose other side effects (e.g., whether a record is created, if it is reversible, or permission requirements). This is partial transparency.

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 exactly two sentences: the first states the core action and output, the second clarifies non-behaviors. It is front-loaded with the primary purpose and contains zero redundant wording. This is an efficient, well-structured description.

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 the tool's moderate complexity (2 parameters, many siblings, no annotation guidance), the description is incomplete. It lacks usage context (when to use vs alternatives), parameter selection guidance, and fuller behavioral disclosure. While the output schema likely covers return details, the description alone does not equip an agent to select or invoke this tool confidently among 15 siblings.

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 description coverage is 0%, meaning the schema has no parameter descriptions. The tool description does not mention either parameter (practice_slug or capability) or explain how to choose a capability. The enum values are self-explanatory but there is no guidance on selection or constraints. The description fails to compensate for the missing schema documentation.

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 verb ('prepare'), the resource ('an expiring, attributed dental action'), and the result ('return a visible patient review URL'). It also explicitly excludes what it does not do ('does not submit patient data or claim a booking'), which helps distinguish it from sibling tools like start_dental_request or confirm_dental_request.

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 usage for preparation rather than execution, but it does not explicitly state when to use this tool over alternatives. It mentions what it does not do, which gives a hint, but there is no direct guidance on selection criteria or mention of sibling tools. Given the large sibling list, this is a moderate gap.

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