skylight_categorize_source_calendar

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. 'Attribute' implies a mutating operation, but the description does not state whether prior attribution is replaced or supplemented, whether the change is reversible, or what side effects occur. This leaves the agent unable to predict the consequences of invoking the 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 a single, front-loaded sentence with no filler. Every word contributes to the core purpose, making it easy for an agent to parse quickly.

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?

There is no output schema and no annotation safety profile, yet the description omits return behavior, side effects, and the role of frameId. For a mutating tool, the agent needs more context to understand what happens after the call and whether prior categorizations are overwritten.

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 schema already documents id and category_ids, and the description adds the conceptual meaning that category_ids refer to family members whose calendars receive these events. However, frameId remains undocumented, and with only 67% schema coverage the description does not fully compensate for that missing parameter.

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') with a specific resource ('a source calendar's events') and names the outcome ('to one or more family members'). It clearly states the tool's purpose, though it doesn't explicitly contrast it with related calendar tools like skylight_update_calendar or skylight_set_default_calendar.

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 gives no guidance on when to use this tool versus alternatives, such as skylight_create_source_calendar, skylight_update_calendar, or skylight_delete_source_calendar. There are no exclusions, prerequisites, or contextual hints beyond the fact that it operates on an existing source calendar.

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