get_recent_updates

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

No annotations are provided, so the description carries the full burden. It discloses the return structure (uri, source_url, change_type) and the behavior of the 'since' parameter (default window). It does not mention rate limits or auth, but these are typical for read tools.

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?

Well-structured with intro, usage scenarios, and parameter list. Reasonably concise, though the usage list could be slightly more compact. Overall effective.

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 the output schema exists, return value details are not needed. Covers purpose, usage, parameters. Missing details like pagination or rate limits, but still adequate.

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 0%, but the description compensates fully: explains 'since' as ISO date lower bound with example, and 'jurisdiction' as optional scope with example. Adds meaning beyond the bare 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 lists 'regulations added or amended recently' and calls it a 'regulatory change feed'. It distinguishes itself from siblings like search_regulations by focusing on recent changes rather than general search.

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?

Provides explicit use cases such as 'what's new in [jurisdiction] compliance' and 'incremental sync of a downstream cache'. While it doesn't explicitly list when not to use it, the context implies alternatives exist (e.g., search_regulations for broader queries).

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