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

Annotations declare readOnlyHint=false, destructiveHint=false and idempotentHint=false, so the safety profile is partly covered. The description adds genuinely new context beyond that: the answer is surfaced to a human reviewer, and it requires the caller's key (auth). It still doesn't say whether answers can be edited or resubmitted.

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?

Front-loads the purpose in the first clause and adds only decision-relevant facts (where to find the dispute, human visibility, key requirement). The choppy fragments ('Seller:', 'Needs your key.') are terse but each carries information.

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 2-param, no-output-schema action tool, the description covers purpose, workflow position, audience, and auth. The main remaining gap is parameter format detail, which neither the description nor the schema provides.

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?

Both parameters are undocumented in the schema (0% coverage), so the description carries the burden. It partially compensates by hinting that dispute_id comes from my_disputes and that 'response' is content shown to the decider, but it gives no format, length, or validation guidance for either field.

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 verb (answer) and resource (dispute), names the actor (Seller) and the triggering event (a buyer opened it). It also distinguishes itself from the siblings open_dispute and my_disputes, so an agent can place it in the dispute workflow without opening any schema.

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 clear context: answer a dispute before a person at Kula Labs decides, and locate the target via my_disputes. It routes the agent to the right sibling for finding the ID but does not state explicit exclusions (e.g., when the dispute is already closed).

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