ncloud_functions_get_trigger_activations

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

The readOnlyHint annotation already communicates safety, and the description adds the monthly time-window scope and a partial return-shape summary (activationId, duration, status, totalCount). It does not disclose pagination behavior or other response details, but the annotation lowers the burden and there is no contradiction.

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?

A single clear sentence with no filler. It front-loads the core operation and resource, then compactly lists the important return fields without wasting words.

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 read-only list operation with fully documented parameters and a readOnlyHint, the description is largely sufficient. It names the fields returned, which matters because there is no output schema, and the schema covers the pagination and platform defaults.

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 all six parameters are already documented. The description adds little beyond restating the one-month window that the schema already covers for start, keeping this at the baseline for fully documented schemas.

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 states a specific action (list), a specific resource (a trigger's activations), and key returned fields. It is clear on its own, but it does not explicitly distinguish itself from closely related siblings like ncloud_functions_get_trigger_activation_detail or ncloud_functions_get_action_activations.

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 gives the temporal scope (last month) but provides no guidance on when to use this tool versus similar list/detail siblings. It does not mention alternatives or exclusion criteria, so an agent must infer the right choice from names alone.

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