create_scheduled_task

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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It mentions launchd and parameter semantics but does not disclose important side effects (e.g., persistent file creation, whether duplicate names are rejected), permissions required, or what happens when both interval and calendar schedules are provided. This is a significant transparency gap for a mutation tool.

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 compact and well-structured, with a terse opening line followed by a clean parameter list. Every sentence adds value; no filler or 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 description covers the basics and parameter meanings but omits critical scheduling semantics, such as how interval_seconds interacts with hour/minute (are they exclusive or additive?). Given the tool's moderate complexity and lack of annotations, this gap makes it only minimally complete.

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 description provides meaningful explanations for all six parameters, including constraints like 'min 60' for interval_seconds and ranges for hour/minute. Since schema description coverage is 0%, this compensates well. However, it could add more nuance about the relationship between interval and calendar 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 'Create a scheduled task using launchd' with a specific verb and resource. It distinguishes itself from sibling tools like list_scheduled_tasks and remove_scheduled_task by focusing on creation.

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 conveys the main use case (creating scheduled tasks) but does not explicitly discuss when to use this tool over alternatives or any exclusions. The context is clear, but there is no direct guidance on choosing between scheduling via interval_seconds versus calendar time parameters.

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