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 only states that this is 'the first question' of a decision guide, giving no information about what the tool does when invoked, what it returns, or whether it has side effects. There is no mention of the expected interaction (e.g., it likely prompts a question) or how it connects to the other checker tools. This is minimal and insufficient for an agent to predict behavior.
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 that is appropriately short. It is front-loaded with the essential information (that it is the first question of a guide). There is no wasted wording, though it could benefit from a bit more 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?
The tool is simple: no parameters, no output schema, and low complexity. However, it is part of a decision guide with sibling tools, and the description does not explain how this tool fits into the overall flow or what happens after it is called. It also does not describe the return value or next steps. Given the lack of an output schema, the description should at least hint at what the agent should expect, but it does not. It is minimally adequate for a start tool but leaves the agent to infer the overall process.
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, so there is nothing for the description to explain. Per the rubric, a baseline of 4 is appropriate when there are no parameters. The description adds no parameter information, but that is not 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 states the tool is 'the first question' of a decision guide, and the title adds 'Start: DIFC or ADGM: route your activity'. This clearly identifies the tool as the entry point for a decision guide, distinguishing it from siblings like checker_answer and checker_tree which likely handle subsequent steps. However, it doesn't specify what the question is or what action the tool performs beyond starting the guide, so it's not a fully precise purpose statement.
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?
There is no explicit guidance on when to use this tool versus the sibling tools. The description does not mention alternatives or conditions for selection. The name 'start' and title imply it should be used first, but that is not stated. An agent must infer the usage context, which is a significant gap.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
