ncloud_search_events

Read-only

Search monitoring events from Cloud Insight by time range, rule, resource, or event ID. Filter unclosed events and paginate results.

Instructions

Search and get monitoring events from Cloud Insight with filtering options.

C2.9/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds almost no behavioral context beyond that: no mention of a mandatory time range, pagination defaults, ordering, or result scope, all of which matter for a paged search. It does not contradict the annotations, but it contributes little.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no filler; the resource and filtering capability are stated immediately. It could use a few more words of routing context, but it wastes nothing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an 8-parameter paged search over events with no output schema, the description is minimal. It omits pagination behavior, the fact that a time range is required, and how results differ from ncloud_search_event_count or ncloud_search_event_by_id, so an agent has just enough to attempt a call but not to choose confidently.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter (query, ruleId, eventId, pageNum, pageSize, startTime, endTime, onlyFetchUnCloseEvent) is already documented in the schema. The description adds no syntax, default, or interaction detail beyond that, matching the baseline 3 for high-coverage schemas.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (search/get) and resource (monitoring events from Cloud Insight), so the agent understands the core operation. However, it does not distinguish itself from close siblings such as ncloud_search_event_by_id, ncloud_search_event_count, or the family of ncloud_list_*_events tools, leaving ambiguity about which event-search tool applies.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'with filtering options' hints at usage but gives no explicit when-to-use context, no prerequisites, and no routing to alternatives like ncloud_search_event_by_id (single event) or ncloud_search_event_count (counts only). The agent must infer the correct tool from names alone.

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