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

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes the creation action and return format, but doesn't mention authentication requirements, rate limits, error conditions, or what happens with duplicate events. It provides basic operational context but lacks comprehensive behavioral details.

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 well-structured with clear sections (Args, Returns) and efficiently documents 14 parameters. While comprehensive, it maintains focus without unnecessary elaboration, though some parameter explanations could be slightly more concise.

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 complexity (14 parameters, 0% schema coverage, no annotations), the description provides substantial context through detailed parameter documentation and return format explanation. The output schema exists, so the description appropriately focuses on input parameters and operational context rather than return values.

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 fully compensates by providing detailed parameter documentation including data types, formats (RFC3339), examples, constraints (max 5 reminders), defaults, and clear explanations of what each parameter controls. This adds substantial value beyond the bare 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 the specific action ('Creates a new event') and resource ('event'), distinguishing it from sibling tools like 'modify_event' or 'delete_event'. It provides a complete functional overview of what the tool does.

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 is provided on when to use this tool versus alternatives like 'modify_event' or 'get_events'. The description lacks context about prerequisites, permissions needed, or typical use cases for event creation versus modification.

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