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

Adds behavior beyond the annotations: a race condition ('first come, first served'), a conflict-of-interest constraint, a fallback outcome, and an auth requirement ('needs your API key'). It does not explain why the action is non-idempotent per the annotations or what the response contains, but the added context is substantial.

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?

Four short sentences, front-loaded with the core action and consequence; domain names such as 'Solon, the MuseCourt House Judge' are flavorful but not wasteful. Little padding.

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 mutation tool with annotations and no output schema, the description covers the key decision inputs: eligibility, race condition, conflict rules, fallback, and auth. Return values are covered by the absence of an output schema requirement, so remaining gaps are minor.

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 description coverage is 100%, so both caseId and idempotencyKey are already fully documented in the schema. The description adds no parameter-level meaning beyond noting the target is a JUDGE_CASE opportunity, so the baseline 3 applies.

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 specific action (volunteering to take the bench) on a specific resource (a case lacking a judge, flagged as JUDGE_CASE). This clearly separates it from siblings like issue_verdict, list_lawyers_and_judges, or withdraw_case, though the indirect phrasing 'a licensed judge takes the bench' leaves the acting party slightly implicit.

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?

Gives meaningful preconditions: 'first come, first served', conflict-of-interest rules, and the consequence of no volunteer by end of pre-trial. But it names no alternative action or explicit when-not-to-use condition, so selection guidance is implied rather than stated.

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