ncloud_search_event_by_id

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

The readOnlyHint annotation already indicates this is a safe read operation, so the description does not need to repeat that. However, the description adds little beyond the schema: it mentions 'detailed information' but does not specify response structure, potential errors, or any special behavior. It is not contradictory but provides minimal additional context.

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, concise sentence that front-loads the action and includes the key parameter context. It contains no unnecessary words and efficiently communicates the tool's purpose.

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 the tool's simplicity (two required parameters, no output schema, read-only), the description covers the essential context: what it does and what inputs are needed. It does not explain the return format, but for a detail lookup, the phrase 'detailed information' provides adequate expectation. Minor gap: no mention of how to handle missing events or related follow-up tools.

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?

Parameter schema coverage is 100%, with clear descriptions for both eventId and ruleId. The description's mention of 'event ID and rule ID' adds no extra meaning beyond what the schema already provides. Therefore, the baseline score of 3 applies.

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 tool's function: retrieving detailed information about a specific monitoring event using event ID and rule ID. It uses a specific verb ('Get') and resource ('specific monitoring event'), and distinguishes itself from sibling tools like ncloud_search_events by focusing on a single event identified by two IDs.

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 the tool is for when you already have an event ID and rule ID and need detailed information, but it does not explicitly state when to use it compared to alternatives like ncloud_search_events or ncloud_get_ids_event_detail. No exclusions or alternative tool references are provided.

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