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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds useful behavioral nuance ('exact outcome', distinct outcome categories), but does not elaborate on lifecycle behavior or failure cases. It does not contradict the annotations.

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, front-loaded with the primary verb and resource. Every phrase adds value, especially the second sentence clarifying that outcome types remain distinct.

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 one-parameter, read-only, idempotent tool with an output schema and strong annotations, the description is mostly complete. It could better define 'expiring dental action' or explicitly state that it applies only to such actions, but an agent can likely proceed with minimal ambiguity.

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%, so the description needed to compensate by explaining action_id and how it relates to the outcome. It does not mention the parameter at all; only the schema's name and length constraints provide any meaning, leaving the parameter semantics mostly implicit.

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 identifies a specific verb ('Read') and resource ('outcome of an expiring dental action'), and adds useful scope by saying handoff, request, and confirmed booking outcomes remain distinct. It does not explicitly name a sibling alternative, but the purpose is unambiguous among the listed siblings.

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 when to use the tool: when the exact outcome of an expiring dental action is needed. However, it gives no explicit when-not-to-use guidance or alternatives, leaving some inference to the agent.

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