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

Annotations already declare the tool is read-only, idempotent, non-destructive, and closed-world. Beyond that, the description adds useful behavior: events are shown at their next appearance, confirmation status is included, and a driver quote is generated and dated once confirmed, distinguishing wine-day quotes from ride quotes.

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 dense run-on sentence with awkward parentheticals and unclear phrasing such as 'which quote takes as to' and 'at their next appearance: id'. It front-loads event types but is not structured for quick parsing.

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 output schema and annotations carry much of the burden, and the description covers event types, date range, confirmation status, and quote behavior. Still, it lacks clear sibling-routing guidance and leaves parameter usage details to the schema, which is adequate but not fully complete.

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 83%, so the schema already documents most parameters. The description refers to the date range and origin/driver quote, but does not clarify query, limit, or lang, and adds little semantic detail beyond the schema baseline.

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 names specific event resources (wine fairs, festivals, auctions, cultural events) and a date range, so the agent can tell what domain it covers. However, it is phrased as a noun list rather than a clear verb+resource statement and does not explicitly distinguish itself from siblings such as quote or plan_wine_day.

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 explicit guidance on when to call find_events versus alternatives like check_availability, plan_wine_day, or quote. The only hint is the cryptic phrase 'which quote takes as to', leaving the agent to infer the workflow.

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