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 only mentions a requirement ('requires explicit adjudication activation and scope') and does not describe side effects, permissions, reversibility, or what happens when evidence is challenged. This is insufficient for a mutation-style tool.

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 two tight sentences with no filler, front-loading the action and adding one constraint. Every phrase earns its place, making it an efficiently worded definition even if it under-delivers on content.

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 has a nested object schema, no annotations, and no output schema, yet the description omits when to use it, what the adjudication activation entails, and what the response looks like. An agent cannot confidently determine correct invocation or expected results from this definition alone.

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 0%, so the description must compensate, but it only loosely maps to 'allegation' and 'evidenceIds'. The semantics of dispute object structure, attestationId, expectedVersion, and idempotencyKey remain unexplained, leaving the agent guessing about concurrency and idempotency requirements.

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 names a specific verb ('challenge') and resource ('accessible evidence') with specific inputs (allegation and evidence IDs), making the core purpose clear. It does not explicitly distinguish from similar siblings like challenge_scientific_claim, but the 'evidence case' framing differentiates it from read/close/vote case tools.

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 guidance is given on when to use this tool versus alternatives, and no sibling tools are referenced. 'Requires explicit adjudication activation and scope' is a precondition, not a usage-selection guideline, so the agent is left to infer the appropriate context.

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