calmesh_create_calendar

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

No annotations are provided, so the description carries the burden. It discloses the auth requirement ('full' scope), return value, and partial failure behavior, which are meaningful operational details beyond the schema.

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?

Two sentences, front-loaded with the action, and no filler. Every sentence adds value: the first states core function, the second covers return behavior and auth prerequisite.

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?

The description covers the main return value and failure mode, and the schema fully documents all parameters. For a create tool with this complexity, it is reasonably complete, though it could briefly mention idempotency or rollback behavior.

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 coverage is 100%, so parameters are already well-documented. The description adds minimal value by clarifying the optional nature of connection_ids, but does not meaningfully enhance the schema descriptions.

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 uses specific verb 'Create' with clear resource 'new unified calendar' and optional 'attach connection sources'. This clearly distinguishes it from siblings like calmesh_list_calendars and calmesh_manage_calendar.

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?

Implies usage through the create verb and mentions optional attachment of sources, which clarifies intended use cases. However, it does not explicitly contrast with alternatives or state when not to use it beyond requiring 'full' scope.

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