skylight_create_event

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

No annotations are provided, so the description must disclose behavioral traits. It states 'Create a calendar event' which implies mutation, but it does not describe side effects (e.g., what happens if the event overlaps with existing events), authorization requirements, or the output format. The description is too sparse to inform an AI agent about the tool's behavior.

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 concise sentence, front-loaded with the verb and resource. However, it is too brief and lacks necessary detail, which is a trade-off. It earns a 4 for being structurally clean but not for completeness.

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 11 parameters, 1 required, no output schema, and no annotations, the description is grossly incomplete. It does not explain the event creation flow, required context (e.g., frameId), or the relationship to other event tools. The agent would be left guessing about how to properly invoke this tool.

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 45% (only 5 out of 11 parameters have descriptions). The description adds no new information about parameters beyond what is in the schema. For example, 'frameId' and 'location' are left undocumented, and the description does not clarify their semantics. Given the low coverage, the description should compensate but fails to do so.

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 action ('Create') and the resource ('a calendar event on a Skylight frame'). The tool name 'skylight_create_event' aligns with this, and it distinguishes itself from sibling tools like skylight_update_event and skylight_delete_event.

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 guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., needing a frameId) or context about recurring events, categories, or invited emails. Siblings like skylight_update_event and skylight_list_events are present, but no differentiation is offered.

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