calendar_create_event

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

No annotations exist. The description lacks any details about side effects, prerequisites (e.g., valid calendar ID), or behaviors beyond the basic creation. For a write operation, more transparency is expected.

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?

Single sentence is concise, but for a tool with 8 parameters and no annotations, more detail is warranted. The structure is minimal but not wasteful.

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 the tool complexity (8 parameters, no annotations, many sibling tools), the description is far too brief. It lacks context about return values, required formats, and relationship to other tools.

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 only 25% (2 of 8 parameters have descriptions). The tool description adds no further parameter meaning, failing to compensate for the low coverage.

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?

Description clearly states the tool creates a calendar event (verb+resource). However, it does not differentiate from sibling tools that also involve events, but since 'create' is unique among siblings, it is clear enough.

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 like calendar_update_event or calendar_get_event. The description does not provide context on usage scenarios.

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