skylight_categorize_source_calendar

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

With no annotations provided, the description must fully disclose behavioral traits. It states the action ('attribute') but fails to mention whether this is a destructive update, if it impacts future events only or past events, if it is reversible, or if specific permissions are needed. This leaves the agent with significant uncertainty.

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 a single sentence that front-loads the action and is free of superfluous words. However, it could be slightly more verbose to include usage context without becoming bloated.

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 this is a modification tool with 3 parameters, no output schema, and no annotations, the description is too sparse. It does not explain the effect of the operation, the return value, or any side effects. A more complete description would include what changes and how to verify the result.

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 description coverage is 67%, with id and category_ids already described clearly in the schema. The description does not add any additional meaning beyond what the schema provides. The undocumented parameter frameId is not addressed, so the description does not compensate for the gap. Baseline of 3 is appropriate.

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 uses a specific verb 'attribute' and clearly identifies the resource (source calendar's events) and target (one or more family members). It distinguishes this tool from siblings like skylight_update_calendar or skylight_list_source_calendars by focusing on categorization, not listing or general updating.

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 does not provide any guidance on when to use this tool versus alternatives, nor does it mention prerequisites such as obtaining the calendar ID from skylight_list_source_calendars or that the category_ids must correspond to family member categories. No when-not-to-use advice is given.

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