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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, which cover safety and idempotency. The description merely restates the read nature with 'Get' and adds no additional behavioral traits such as authentication requirements, rate limits, or data volatility. Thus, it provides no extra value beyond the annotations.

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 sentence of 10 words, succinctly listing the three output categories. It is front-loaded with the verb and immediately conveys the tool's purpose. Every word serves a clear function, with no redundancy.

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 tool has no output schema, so the description partially explains return values by listing three content types. However, it does not specify the format (e.g., structured document, plain text) or whether additional details are available. Given the simplicity (0 parameters, no nested objects), this is mostly adequate but leaves a minor gap in completeness.

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 tool has zero parameters, and the input schema is empty with 100% coverage. Per the guidelines, baseline score for 0 parameters is 4. The description does not need to elaborate on parameters.

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 retrieves three specific categories of safety-related information: monitoring limitations, urgent animal-welfare guidance, and prohibited claims. The verb 'Get' aligns with the tool name, and the resource 'safety limits' is expanded. This specificity distinguishes it from siblings like get_camera_requirements or get_market_route.

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?

No explicit guidance on when to use this tool versus alternatives is provided. The description implies use for safety-related queries, but does not mention exclusions or criteria for when other tools (e.g., search_public_knowledge) might be more appropriate. The context is clear but lacks directive support.

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