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

With no annotations, the description carries the full burden. It does disclose the honesty/grounding constraint ('fabrication (grounded:false) doesn't win') and the shape of the returned verdict, which is genuine behavioral context. It says nothing about side effects, cost, or whether the call is read-only, so significant gaps remain.

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?

Dense and front-loaded in a single compact block, with the action first and parameter domains trailing. Every clause carries information, though the telegraphic style slightly hurts readability.

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 tool taking a nested, structurally undocumented tree object with no output schema and no annotations, the description is on the thin side. It covers return values and enum domains but leaves the tree's expected shape and the operating context underspecified.

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?

Schema coverage is 0%, so the description is the only source of parameter meaning, and it does substantial work: it defines the opponent domain {self,person,world}, the stance domain {competitive,cooperative}, and characterizes tree as a tree of moves for you and the opponent. The internal structure of the tree object is still left unexplained.

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?

States a concrete verb and resource: evaluate a move tree (you + opponent) and return an evaluation, main line, and verdict. An agent can grasp the operation without opening the schema. It does not, however, distinguish itself from close siblings like situation_stress_test or capture_situation.

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?

No when-to-use guidance, no prerequisites, and no alternatives named among the many decision-analysis siblings. The enum hints for opponent/stance are parameter facts, not usage routing.

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