listViolators

Read-onlyIdempotent

Provide details about one issue in one report, including basics about the elements of the tested page that were reported as exhibiting the issue. Kilotest tests web pages for front-end quality (accessibility, usability, and standards conformity); results are organized as report, then issue, then violator element, then diagnosis.

  3. First observed

TDQS

C2.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds domain context (what Kilotest is and how results are organized) but nothing about result shape, pagination, or the relationship to the diagnosis level beyond the hierarchy list.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no filler, with the output scope stated first and the domain model second. It is appropriately short for a read-only lookup, though the opening sentence could have named the tool's actual resource (violator elements) more directly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists so return values needn't be explained, and annotations cover safety, leaving little for the description to carry. Still, it fails to position this tool against listIssues/listDiagnoses, which is the main gap for a crowded sibling set of eleven tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with each of jobID, issueID and timeStamp documented including formats and examples, so the schema carries the parameter burden. The description contributes no additional meaning about how these three identifiers combine to scope the query, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description says it provides details about one issue in one report including the elements exhibiting that issue, and it lays out the report→issue→violator→diagnosis hierarchy. However, it never uses the word 'violator' and reads more like a single-issue lookup than a listing tool, so the verb+resource is muddled and it does not distinguish itself from siblings listIssues or listDiagnoses.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit when-to-use guidance and no alternatives named, even though listIssues and listDiagnoses are obvious candidates for confusion. The hierarchy sentence only implicitly hints at when this tool fits (after you have a jobID/issueID/timeStamp).

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