create_action

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 does not mention side effects, validation, failure modes, or whether the operation is reversible. The only behavioral hint is the word 'Create' implying a mutation, but nothing else.

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 sentence plus a list, with no filler. It front-loads the core action and includes useful enum information. It could be slightly more structured by explicitly labeling parameters, but it is appropriately 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?

For a create operation with three parameters and no annotations, the description is too thin. It does not explain prerequisites (e.g., activity existence), what happens on invalid action_type, or any constraints. The output schema exists but does not compensate for the lack of behavioral and usage context.

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 0%, so the description must compensate. It does explain action_type by listing its possible values (OpaqueAction, CallBehaviorAction, SendSignalAction), but it leaves name and activity_id completely undefined. While these may be inferable from context, the description does not explicitly map them, leaving a significant gap.

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 action: 'Create an Action inside an Activity.' It specifies a verb and resource, and even lists possible action_type values, making the purpose unambiguous. However, it does not explicitly differentiate from other create_* tools like create_element, which could be ambiguous without additional context.

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 given on when to use this tool versus alternatives. It does not mention prerequisites (e.g., that the activity must exist), nor does it exclude use cases. The description is purely declarative and offers no decision support.

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