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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds valuable behavioral context: it returns links to FDA meeting pages, defaults to a 90-day window, and has limited historical coverage starting late 2025. This exceeds the annotation information without contradicting it.

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 compact (three sentences) and front-loaded: the first sentence states the core function, the second clarifies defaults, and the third clarifies limitations and scope. No filler or redundant information.

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?

For a simple read-only calendar tool with no output schema, the description covers the essentials: what is returned, the source, defaults, coverage limitations, and what it is not. It does not detail the exact output fields, but that is not critical given the simplicity and the provided link. It is complete enough for an agent to decide when and how to call it.

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?

The schema already fully describes all three parameters with defaults and formats (100% coverage). The description's mention of 'next 90 days' and 'date range' echoes the schema without adding new meaning. Thus the description adds no significant value for parameter understanding, though it is consistent with the schema.

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 purpose: retrieving scheduled FDA advisory-committee meetings from the FDA.gov calendar, each with a link to its meeting page. It also specifies the scope (forward-looking, not historical) and the coverage start date, which distinguishes it from other calendar tools in the sibling list like GetEconomicCalendar or GetMarketHolidayCalendar.

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 provides explicit usage context: it is for forward-looking FDA advisory-committee meetings, not a historical archive, and coverage starts in late 2025. It also notes entries are not linked to stock tickers, indicating it is not for market-impact analysis. While it does not name specific sibling tools, it clearly frames when this tool is appropriate and when it is not.

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