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

No annotations are provided, so the description must carry the full behavioral burden. It only states that this is the first question in a guide, without disclosing whether calling it mutates state, advances the guide, requires prior context, or returns a question payload. An agent cannot predict the tool's side effects or output.

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 with no filler or redundancy. It is appropriately sized for a zero-parameter entry-point tool, though it could use slightly more behavioral detail without becoming verbose.

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 there is no output schema and no annotations, the description is incomplete: it does not say what the agent will receive after calling the tool, how to proceed after the first question, or what the decision guide flow looks like. This is minimally viable but lacks enough context for confident invocation and follow-up.

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 takes zero parameters and the schema is empty, so there are no parameter semantics for the description to clarify. The baseline of 4 applies because no parameter information is needed beyond what the empty schema already communicates.

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 in the Bin rules checker decision guide, which distinguishes it from the sibling answer/tree tools by position. However, it lacks an explicit verb describing what actually happens when invoked—whether it starts the guide, displays a question, or returns some data—so purpose is only vaguely stated.

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 phrase 'first question of the Bin rules checker decision guide' implies this tool is the intended entry point for that workflow. It does not name alternatives or explain when to prefer checker_answer or checker_tree, so the guidance is implicit rather than explicit.

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