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

With no annotations, the description must carry the behavioral burden. It helpfully labels the tool as a PUBLIC WRITE and discloses the tri-tier outcomes tied to Kappa ranges, but it does not clarify permissions, reversibility, or exactly what is written or committed in the Auto-Commit case.

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 front-loaded sentence that starts with the PUBLIC WRITE classification and then gives the core purpose and thresholds. It is efficient, but the dense jargon around '4-choice conflicts' and '7-turn queries' reduces immediate 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 an 8-parameter arbitration tool with no annotations and no output schema, the description covers the operating condition and Kappa decision tiers but leaves the return behavior and side-effect semantics underspecified. It is workable, but an agent still lacks enough detail to know exactly what the arbitration call produces or commits.

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 the baseline is 3. The description adds useful meaning for kappa by mapping score ranges to concrete arbitration outcomes, and it implicitly links conflict-resolution and seven-turn modes to the corresponding flags, though it does not explain target_id, confidence, or token_estimate.

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 states a specific verb and decision domain: arbitrating actions, conflicts, and 7-turn queries under Kappa thresholds when a human is unattended/headless. It is clearly a gate/arbitration tool rather than a generic verify or accept/reject tool, though it does not explicitly distinguish itself from nearby siblings such as verify_action_safety or accept/reject.

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?

It gives a clear triggering condition: use when the human is unattended or headless. However, it does not name alternatives or state exclusions, so an agent must infer when verify_action_safety, accept, or reject would be more appropriate.

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