get_live_time_gaps

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

No annotations provided. Description adds mode-awareness and auth requirement, but does not disclose other behavioral traits like caching, real-time update frequency, or response content beyond what is implied.

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 key functionality and unique feature (mode-aware). No wasted words.

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 zero-parameter tool with output schema, the description covers what data is returned (gap to leader, interval to car ahead) and mode-awareness. Additionally mentions auth requirement. Sufficient for agent to understand and invoke tool.

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?

No parameters in input schema. Schema coverage is 100%, so description does not need to add param info. Baseline of 4 is appropriate for zero-param tool.

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 clearly states it provides live gap to leader and interval to car ahead, mode-aware. Distinguishes from sibling live tools by specifying the exact data type (time gaps).

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. Only states 'No auth required', but does not mention exclusions or comparisons with sibling tools.

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