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

With no annotations, the description carries the full burden of behavioral disclosure. It conveys that the tool exposes every question, option, and verdict, which implies a read-only informational retrieval, but it does not mention output format, size, or any potential limitations. The behavior is adequately hinted but not fully specified.

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 focused sentence that front-loads the scope ('Every question, option and verdict') and immediately states the purpose. There is no extraneous wording or repetition of the title.

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 no-parameter tool with no output schema, the description tells the agent what content will be returned and why it is useful. It stops short of explaining the return structure or how the tree is organized, but the core information needed to invoke the tool correctly is present.

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 100% schema description coverage, so there is no parameter ambiguity. Per the baseline for zero-parameter tools, the description does not need to compensate for missing parameter documentation.

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 clearly identifies the resource (the complete decision tree for the Malta work permit checker) and its intended use (reasoning end to end). It lacks an explicit verb like 'returns' or 'provides,' but it is not a tautology and is distinguishable from the checker_answer and checker_start siblings by its scope.

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 'for reasoning end to end' gives a clear intended use case and implies this tool is for full-tree exploration rather than single-answer lookup. However, it does not explicitly state when to prefer this over checker_answer or checker_start, nor does it mention any exclusions.

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