md_traffic_cameras

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful context about return contents (IDs, locations, image URLs) but does not disclose potential behaviors like data freshness, pagination, or image accessibility.

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?

Two sentences, front-loaded with the core action and resource, followed by return value details. No redundant or extraneous 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 no-parameter, simple listing tool, the description adequately covers what it does and what it returns. Slight gap: 'locations' is ambiguous (coordinates vs. descriptive location), and no mention of whether all cameras are returned or if any limits apply.

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, so the baseline is 4. The description adds no parameter-specific detail, but none is needed since the schema trivially covers everything.

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?

Description uses specific verb 'Get' and resource 'traffic camera locations across Maryland highways', clearly stating what the tool returns (camera IDs, locations, image URLs). It distinguishes from siblings like md_traffic_incidents and md_traffic_speeds by focusing on cameras and visual monitoring.

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?

States the purpose of real-time visual monitoring, providing contextual use. Does not explicitly mention when not to use or name alternative tools, but the scope is clear enough among the Maryland traffic sibling tools.

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