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

No annotations are provided, so the description carries the full burden of explaining behavior. It only states that this is the first question, but does not disclose what invoking the tool returns, whether it changes any state, or how the question is presented. This is insufficient for a tool that is part of an interactive decision guide.

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 sentence with no wasted words. It front-loads the key fact that this is the first question of the guide. For a tool with no parameters, this level of conciseness is appropriate.

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 zero-parameter schema and no output schema, the description is thin on operational context. It does not explain what happens after starting, how the decision guide progresses, or how the sibling tools relate. An agent would need to guess the follow-up actions, making the description incomplete for effective invocation.

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 zero parameters, so the baseline is 4. The description reinforces that the tool is a starting point requiring no input, which is consistent with the empty schema. No parameter clarification is needed, and the description adds appropriate minimal context.

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 a decision guide, which indicates it is the entry point. However, it lacks a concrete verb describing what the tool actually does (e.g., 'starts' or 'displays'), making the purpose somewhat vague. It is not a pure tautology, but it mostly paraphrases the title without adding operational clarity.

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 the tool should be used first, but it gives no explicit guidance on when to use it versus the sibling tools like checker_answer or checker_tree. There is no mention of the overall flow or that later steps involve answering questions. An agent is left to infer usage from the title and sibling names.

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