create_event

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

No annotations exist, so the description must fully disclose behavior. It mentions parameter formats but omits side effects, permissions, error conditions, or whether the event is saved immediately. Minimal behavioral insight beyond creation.

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?

Extremely concise: two sentences covering purpose and key parameter notes. No fluff, front-loaded with the main action. Efficient use of space.

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 7 parameters and an existing output schema, the description covers creation intent and some key fields but lacks complete context: no mention of return value, error handling, or linkages to other entities beyond location_id. Adequate but not thorough.

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?

With 0% schema description coverage, the description adds meaning for 4 of 7 parameters: start/end format (ISO 8601), staff_id required, location_id type. However, name, case_id, and description lack any semantic addition beyond the schema.

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 calendar event' and gives key parameter hints (ISO 8601 formats, required staff_id). It distinguishes from siblings like update_event or delete_event by the verb 'create', but does not explicitly contrast with similar creation tools like add_staff_to_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?

No guidance on when to use this tool versus alternatives (e.g., update_event, add_staff_to_event). No prerequisites or context provided. The description only specifies parameter details, not usage scenarios.

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