timer_timer_benchmark

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

No annotations provided, so description carries full burden. It discloses return format and that it runs the command N times, but omits side effects (e.g., command might produce output, modify files), timeout behavior, or error handling. Minimal but adequate.

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?

Single sentence, front-loaded with tool purpose and return format. 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?

Has an output schema (return values described in description), but input parameters are not explained. Given low complexity (3 params, 1 required), description is partially complete but missing parameter details.

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 coverage is 0%, and the description does not explain any parameters (command, runs, timeout_s). It only mentions 'N runs' but does not clarify that 'runs' is the parameter name. Fails to compensate for missing schema descriptions.

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 it benchmarks a shell command with N runs and returns timing metrics (avg, min, max, total ms). It distinguishes from sibling timer tools like timer_timer_start (stopwatch) and timer_timer_elapsed (elapsed time).

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 implies usage for benchmarking but does not explicitly state when to use this tool vs alternatives like timer_timer_start or timer_countdown_*. No when-not or alternative tools mentioned.

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