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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely says this is the first question, but it does not explain what happens when called, whether any state changes, or what the agent should expect in response. The behavioral surface is effectively undisclosed.

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 a single concise sentence and is easy to parse. It adds the 'decision guide' context, but it is close to being a restatement of the title, which slightly reduces its value. Still, there is no unnecessary verbosity.

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 zero-parameter entry point, the description is mostly adequate: it tells the agent this is the first question of the guide. However, with no output schema, it does not clarify what the tool returns or how to proceed after invoking it, leaving the agent with an incomplete picture of the interaction.

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 tool has zero parameters and the schema description coverage is 100%, so there is no parameter behavior to explain. The baseline of 4 for a zero-parameter tool is appropriate because no additional parameter semantics are needed.

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 identifies the tool as the first question of the Identity verification deadline checker decision guide, which makes its role as an entry point clear. However, it stops short of an explicit action verb like 'start' or 'initialize', and it largely restates the title. It is distinguishable from siblings by the 'first question' positioning, but the differentiation is implicit.

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 provided about when to call this tool versus the sibling tools such as checker_answer or checker_tree. The phrase 'first question' implies it should be used first, but there is no explicit instruction about invocation flow or alternatives.

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