ncloud_get_activity_logs

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

Annotations already declare readOnlyHint=true, so the description adds value by stating HTTP method (POST), body format (JSON), and internal conversion of timestamps. However, it omits details about pagination behavior, response format, error handling, or any limitations.

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?

Description is concise with three sentences: purpose, method, and time behavior. It front-loads the key action. Could be slightly more streamlined by moving method detail to the end.

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 5 parameters with 100% schema coverage, no output schema, and readOnlyHint annotation, the description is incomplete. It fails to explain pagination (page/size parameters), lacks details on response structure, and introduces filtering parameters (service, user) not present in the schema, which may mislead an agent.

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 descriptions cover 100% of parameters, so baseline is 3. The description clarifies that time parameters accept ISO 8601 strings and are converted to epoch milliseconds internally, adding value beyond schema. But it mentions 'service and user' filtering which doesn't appear in the schema, causing potential confusion.

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 'Get cloud activity tracer logs' and mentions filtering by period, service, and user. However, the input schema only includes 'nrn' for filtering, not separate service/user parameters, creating slight ambiguity. It does not distinguish from sibling tools like ncloud_get_activity_detail or ncloud_search_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?

No explicit guidance on when to use this tool versus alternatives. Missing context about prerequisites, scenarios, or when not to use. The description does not help the agent decide between this and other logging tools.

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