C2.1/5.0
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals that some operations need confirmation, but it does not explain side effects, whether actions are mutating/destructive, what happens when confirm is false, or any other behavioral consequences.

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

Conciseness3/5

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

The description is short and not verbose, but the opening sentence is mostly filler. The second sentence about confirm adds useful context. Overall it is minimally structured but not egregiously wasteful.

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

Completeness2/5

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

Despite the presence of an output schema, the description is severely incomplete for a generic trigger tool with an undocumented required path parameter. An agent cannot determine what paths are valid, what values mean, or how confirm affects execution, making this inadequate for reliable invocation.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate, but it only partially explains confirm. The required path parameter and the value parameter are completely unexplained in terms of valid formats, meaning, or examples.

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

Purpose2/5

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

The description 'Trigger an action' essentially restates the tool name and provides no concrete resource or domain. It does not distinguish this tool from specialized siblings like xr18_set or xr18_snapshot_load, leaving the agent to guess what kind of action is being triggered.

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 only usage guidance is that console initialization and network updates require confirm=true. There is no statement about when to prefer this tool over the many sibling tools, nor any exclusions or alternative routing guidance.

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