parse_ufixit_violations

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

The annotation readOnlyHint: true covers the safety profile, and the description does not contradict it. However, the description adds no extra behavioral context beyond what the annotation provides, such as return format or side effects, but given the annotation, this is adequate.

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 zero waste. It is concise and immediately conveys the purpose and input source.

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?

The tool is simple (one parameter, read-only, no output schema). The description specifies the input source and outcome. While it does not detail the exact structure of extracted violations, for a parsing step this is acceptable given the low complexity and good annotations.

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 coverage is 100%, with the parameter report_json described as 'JSON string from fetch_ufixit_report'. The tool description does not add additional meaning beyond the schema, so the baseline of 3 is appropriate.

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 clearly states the tool's function: parsing UFIXIT report content to extract accessibility violations. It uses a specific verb (parse) and resource (UFIXIT report content), and it distinguishes itself from siblings like fetch_ufixit_report (which fetches) and format_accessibility_summary (which formats).

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?

The description implies usage by mentioning the input comes from fetch_ufixit_report, which situates it in a pipeline, but it does not explicitly state when to use it versus alternatives or provide exclusions. The context is clear but not explicit about alternatives.

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