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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses the content scope and the reasoning purpose, but it does not describe the output format, size, structure, or how the tree is meant to be traversed. This is a partial disclosure, not a complete one.

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 that front-loads the core content and ends with the purpose. There is no filler, redundancy, or irrelevant detail; every phrase earns its place.

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 description tells an agent what content is included and why it might be useful, but with no output schema and no annotations, it leaves out important operational details such as the expected response structure and how the returned tree relates to the interactive checker tools. It is adequate but incomplete for fully informed 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 tool has zero parameters, so the baseline for this dimension is 4. The description correctly does not attempt to explain parameter behavior that does not exist, and no schema compensation is 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 clearly identifies the resource: every question, option, and verdict in the P11D changes checker guide. It goes beyond the title by specifying the content scope and intended use. It lacks an explicit verb such as 'returns' or 'retrieves', but the intended function is still clear.

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' implies the tool is meant for full-tree traversal rather than step-by-step interaction, which distinguishes it from siblings like checker_start and checker_answer. However, there is no explicit guidance on when not to use it or which alternative to choose in specific situations.

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