ncloud_functions_invoke_action

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

Annotations are empty, so the description carries full behavioral burden. It only discloses that the execution result is returned, but does not mention whether the invocation is synchronous, how timeout affects behavior, side effects of running user code, or error/return format. This is insufficient for a tool that executes arbitrary functions.

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 sentence, front-loaded with the core action, and no redundant words. Every word adds value by specifying the resource and the return behavior.

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 empty annotations, no output schema, and a complex operation that runs user code, the description is too minimal. It lacks return value structure, timeout semantics, platform-specific behavior, and error handling context. The schema covers parameters but nothing about execution context or result format.

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% description coverage for all five parameters, including defaults, constraints, and descriptions. The tool description adds no extra parameter semantics beyond what the schema already provides, so it meets the baseline but does not exceed it.

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 states a specific verb 'Invoke' with a specific resource 'Cloud Functions action', and adds 'return the execution result' which clarifies the synchronous behavior. This clearly distinguishes it from siblings like ncloud_functions_invoke_trigger, ncloud_functions_create_action, and ncloud_functions_get_action.

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 on when to use this tool compared to alternatives like ncloud_functions_invoke_trigger or ncloud_functions_get_action. There is no mention of prerequisites, blocking vs async invocation, or scenarios where a different Functions tool would be appropriate.

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