clear_day_content

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

No annotations are provided, so the description carries the full burden. It discloses the action (clearing content), the intended use case (post-activity-conversion cleanup), and a safety constraint (not allowed when 0 activities). It does not detail side effects or reversibility, but for a simple clear operation, it is sufficiently transparent.

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 very concise: a single Korean sentence stating the purpose, a warning note, and an Args list. Every element serves a distinct role without redundancy, and the main action is front-loaded.

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?

With an output schema present (though not shown), the description does not need to explain return values. The two required parameters are simple integers, and the description includes a safety note about activity count. It covers the essential context for a clear-content tool, though it could mention what 'content' refers to (markdown).

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 0% description coverage, and the description only lists the parameter names (trip_id, day_id) without adding any meaning beyond the schema. The parameter names are somewhat self-explanatory, but the description does not compensate for the lack of schema descriptions by providing types, formats, or examples.

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 the tool's purpose: clearing the markdown content of a day (일자의 마크다운 콘텐츠를 비운다) and specifies it is for cleanup after activity conversion. This distinguishes it from sibling tools like delete_day (which removes the day entirely) and update_day (which modifies day details).

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 a critical usage condition: it cannot be executed when there are 0 activities (to prevent data loss). This gives clear guidance on when not to use the tool. However, it does not explicitly compare to sibling tools or specify when to use this tool over others.

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