validate_candidate_pipeline

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

With no annotations provided, the description alone must disclose side effects and operational behavior. It only says 'compare' and 'return evidence,' but does not clarify whether the pipeline is executed, whether the operation is read-only, or what the evidence consists of.

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 with no filler. It is concise, but the brevity contributes to important missing details about behavior and parameters.

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?

Given three parameters, no annotations, no output schema, and no sibling tools, the description is too thin. It does not define what the returned 'evidence' looks like, what 'trusted reference' means, or what the parameters control.

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%, and the description does not explain seed, faults, or row_count, nor how they affect the comparison. The enum values for faults hint at their meaning, but the description adds no parameter-level semantics.

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: compare a candidate taxi pipeline with a trusted reference, then return evidence. The verb and object are clear, though 'trusted reference' and 'pipeline' remain somewhat domain-specific and undefined.

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 about when to use this tool versus alternatives, no prerequisites, and no mention of when it should not be used. The only implicit cue is that it is for validating a candidate pipeline.

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