reset_vcenter_alarm

Reset triggered vCenter alarms to cleared state after resolving the underlying issue. Alarms are removed from the active alarm list.

Instructions

[WRITE] Reset a triggered vCenter alarm to cleared state (gray).

Clears the alarm completely — it will no longer appear in the active alarm list. Use this after resolving the underlying issue. Use list_vcenter_alarms to find entity_name and alarm_name values.

Args: entity_name: Name of the entity with the alarm (VM name, host name, or cluster name). alarm_name: Exact alarm definition name from list_vcenter_alarms output. target: Optional vCenter target name from config.

Behavior3/5

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

Annotations already indicate non-read-only, non-destructive, non-idempotent, and open-world. Description adds that the alarm is cleared completely and removed from active list, but no additional side effects or auth needs.

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?

Description is well-structured with a header, summary, usage hint, and parameter list. Slightly verbose but overall efficient.

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?

No output schema; description does not mention return value. Prerequisites partially covered. Lacks detail on error conditions or state prerequisites (e.g., alarm must be triggered). Adequate for a simple tool but has gaps.

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

Parameters5/5

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

Schema description coverage is 0%, but the description explains all three parameters clearly in the Args section, providing meaning beyond the schema.

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?

Description clearly states it resets a triggered vCenter alarm to cleared state. It uses specific verbs and resource, but does not differentiate from sibling 'acknowledge_vcenter_alarm'.

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

Usage Guidelines3/5

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

Provides usage context: use after resolving the underlying issue, and references list_vcenter_alarms for finding parameter values. No explicit when-not-to-use or alternatives mentioned.

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