get_recent_updates

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

No annotations provided, so the description must do all the work. It clearly states the ordering (newest first), optional time window (days parameter), type restriction (update_type), and default behaviors. It doesn't explicitly state if this is a read-only operation, but the verb 'Get' strongly implies it, and nothing suggests side effects. A small gap is not mentioning pagination or what happens with empty results.

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?

Three sentences, zero fluff. The purpose is front-loaded in the first sentence, usage guidance in the second, and optional parameter usage in the third. Every sentence earns its place without repetition.

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?

Despite no output schema and moderate complexity (4 params, 2 enums), the description is fully self-contained. Agents can understand what the tool does, when to use it, and how to use the parameters. The absence of output schema is compensated by the clear behavior description (list of recent advisories).

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 already covers all 4 parameters with descriptions (100% coverage), so baseline is 3. The description adds value by explaining the purpose of the date filter and the update_type restriction with concrete examples like 'Regional advisory added', which goes beyond the schema's terse description. However, it doesn't add context for limit or language beyond what the schema provides.

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 explicitly states the tool gets the most recently updated advisories, ordered newest first. It clearly distinguishes itself from siblings like get_travel_advisory (single advisory) and list_travel_advisories (likely a listing without update recency) by focusing on recency and change tracking.

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 directly says 'Use this for "what changed this week" questions', providing a concrete usage scenario. It also explains optional restriction by update_type, giving agents clear guidance on when to apply that parameter.

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