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 behavioral disclosure. It does not state what invoking the tool does—whether it starts a session, presents a question, advances state, or returns data. The noun-phrase description leaves the actual behavior largely implied.

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 filler and it front-loads the essential role of the tool. It earns its place, though it is too sparse to provide deeper context.

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?

With no output schema and no annotations, the description should explain what the agent will receive and how to proceed. It only says 'first question' without clarifying the response format or the next step, so an agent has incomplete guidance for using this tool effectively.

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 schema description coverage is 100%, so there is no parameter documentation burden for the description to carry. Nothing is missing here.

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 a specific resource—the EV charger checker decision guide—and states that this tool is the first question, making it clear this is the entry point. It does not use an explicit action verb like 'starts' or 'initiates', but the title 'Start' and the phrase 'first question' make the purpose reasonably clear. It also implicitly distinguishes itself from answer/tree 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?

Usage is implied: call this tool first when beginning the EV charger checker decision guide. However, there is no explicit guidance about when not to use it, no mention of alternatives, and no indication of how it connects to checker_answer or checker_tree.

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