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 return format ({verdict, reason}), which is genuine behavioral value given there is no output schema. However it omits auth requirements, whether the call mutates state, and what happens on rejection beyond returning a 'reason'.

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?

A single compact sentence with the purpose and return shape front-loaded. The only waste is the branding phrase, which consumes space without adding selection value.

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 6-parameter tool with no annotations, no output schema, and zero parameter documentation, this is thin. The description compensates for the missing output schema by stating the verdict/reason return, but leaves the parameter semantics and invocation preconditions entirely unexplained.

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?

Six parameters (input, title, result, taskId, attemptId, description) with 0% schema description coverage, yet the description explains none of them. It only vaguely implies a 'worker delivery' and 'task requirements' exist, leaving the agent to guess which field holds what.

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 and resource: it 'evaluates a worker delivery against task requirements' and names the return contract ({verdict: accepted|rejected, reason}). This distinguishes it from siblings like verify_payment_and_unlock or submit_buyer_offer. The branding prefix ('Autonomous brick.blue Validator & Task Judge') is noise, but the operational purpose is clear.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives among the sibling tools. The agent must infer that this is for judging a worker's delivered result, but nothing states required preconditions or when validation should be skipped.

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