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

With no annotations, the description carries the burden and does meaningful work: it states the data is live, limited to OPEN violations, and never stored or logged by the server. It could add authentication/rate-limit details, but the privacy and live-data traits are valuable beyond the tool name.

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 purpose is front-loaded in the first sentence, the return payload is summarized in one sentence, and privacy is one final sentence. It's dense but not padded; every sentence contributes.

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 there is no output schema, the description compensates by enumerating the return fields (ticket details, totals owed, judgment outlook, boot-risk threshold, dismissal rate). It doesn't spell out error handling or exact response structure, but an agent has enough to understand what comes back.

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 100%, so the schema already explains plate, state, and license_type with examples and the advice to omit license_type. The free-text description adds little parameter detail beyond saying the plate is a New York plate, which is already implied.

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 opening sentence names a specific action (look up every OPEN parking and camera violation) and resource (City of New York's public Open Data API). It is clear enough to distinguish from sibling tools like borough_odds or deadline_calculator, though it never explicitly names an alternative such as violation_dismissal_rates.

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 gives no when-to-use guidance or exclusions versus siblings. It implies usefulness for checking current tickets and boot risk, but it never tells the agent when to prefer this tool over violation_dismissal_rates or other lookup tools.

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