linux_cron

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

No annotations are provided, so the description carries the full burden. While it mentions generating and validating cron expressions, it does not disclose any behavioral traits such as permissions required, side effects, or whether the tool is read-only or destructive. The absence of such information limits transparency.

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 three sentences long, front-loaded with the core purpose. The first sentence ('Menu ID: linux_cron. Cron Job Generator') is somewhat redundant but not overly verbose. It efficiently communicates the tool's function and directs to further guidance.

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?

Given the tool has no output schema, the description should explain return values. It mentions 'human-readable explanations' but does not detail the output format or behavior of the visual builder. The description is incomplete for an agent to fully understand what to expect.

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 input schema has no defined parameters but allows arbitrary inputs via additionalProperties. With schema coverage at 100% (no parameters), the baseline is 4. However, the description does not guide on what inputs the tool expects or how to structure them, which is a gap. It only mentions cron expressions, but lacks parameter documentation beyond the schema.

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 is a 'Cron Job Generator' that 'generates and validates cron expressions' with a visual builder, establishing a specific verb and resource. However, it does not explicitly distinguish itself from the sibling tool 'time_cron_parser', which also deals with cron expressions, though the generation vs. parsing difference is implied.

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 provides no explicit guidance on when to use this tool versus alternatives. It only mentions using 'describe_tool' for full guidance, but does not state when to choose this tool over similar ones like 'time_cron_parser' or other linux tools.

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