calendar_quick_add

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

No annotations provided. Description mentions creation but does not disclose side effects, required permissions, or whether events are created immediately. Minimal behavioral context beyond the action itself.

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 concise sentence with an illustrative example. No wasted words, but could be slightly expanded for clarity on use-case differentiation.

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 simple tool with no output schema, description is adequate but lacks details on parsing behavior, error handling, or distinction from 'calendar_create_event'. Complete for basic use but not for nuanced understanding.

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 has 100% coverage with descriptions for all three parameters. Tool description adds a conceptual example but no extra semantic detail beyond what the schema provides. Baseline 3 is appropriate.

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 'Create a calendar event from a natural language string' with an example. Verb 'Create' and resource 'calendar event' are specific. Distinguishes from sibling 'calendar_create_event' which likely requires structured input.

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?

Description implies usage via natural language but does not explicitly state when to use this over alternatives like 'calendar_create_event'. No when-not-to-use or prerequisites mentioned.

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