create_action

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Create an action' and does not explain persistence behavior, validation, authorization needs, idempotency, or what the tool returns. For a mutating operation this is a notable gap, though nothing is misleading.

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 a single front-loaded sentence that communicates the core purpose, the resource type, and the key optional linkage with no filler. Every word contributes useful information.

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 tool is moderately complex with six parameters, but the schema covers all of them and there is no output schema requiring explanation. However, with no annotations and a very terse description, the agent is left without information about response behavior, failure modes, or constraints such as whether a linked event must already exist. It is adequate for basic invocation but not fully context-complete.

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 100%, so the schema already documents all six parameters in sufficient detail. The description adds only the context that actions are tasks/to-dos and can be linked to an event, which maps to event_id, but it does not add meaningful detail 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 a specific verb ('Create'), a distinct resource ('an action (task/to-do)'), and a meaningful qualifier ('that needs to be taken, optionally linked to an event'). It differentiates from create_event by clarifying that actions are tasks/to-dos rather than calendar events.

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?

The description implies usage by defining what an action is, but it does not explicitly state when to choose this tool over alternatives or when not to use it. The closest sibling alternative, create_event, is only implicitly excluded by the 'action (task/to-do)' framing rather than through explicit routing guidance.

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