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 that the tool 'Shows equivalent, overlapping, stricter, and weaker mappings between regulations,' giving concrete insight into the output nature. It does not mention safety, but the read-only nature is implied by 'comparison' and 'shows,' which is adequate for this low-risk tool.

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 two concise sentences, front-loaded with the primary action and output. Every sentence adds value: the first states the function, the second details the output and use case. No redundancy or filler.

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?

With no output schema and no annotations, the description compensates by explaining the nature of the output ('equivalent, overlapping, stricter, and weaker mappings'). It covers purpose, use case, and output content sufficiently for a simple two-parameter tool, though it could mention default behavior or limitations.

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%, with both parameters documented (category options and optional jurisdictions with default). The description adds only minimal semantic value by framing category as 'compliance category' and jurisdictions as 'across borders,' so a baseline score of 3 is appropriate.

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 compares regulatory obligations across jurisdictions for a compliance category, using a specific verb ('compare') and resource ('jurisdictions'). It distinguishes itself from sibling tools (check_deadline, check_obligations, get_regulation_articles) by emphasizing cross-jurisdictional mapping rather than deadline checking or article retrieval.

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 explicitly says 'Use this to understand how requirements differ across borders,' providing clear usage context. It does not mention when not to use it or explicitly name alternatives, but the context is sufficiently clear for an agent to select it over siblings.

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