vrm_get_vebus_warnings_alarms

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

No annotations are provided, so the description bears full responsibility for disclosing behavioral traits. It states the tool retrieves warnings/alarms but does not clarify whether it is read-only, what permissions are needed, or any side effects. This is insufficient for a tool that could be used for diagnostics.

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 extremely concise with two sentences. The first sentence clearly states the purpose, and the second adds a key feature with an example. There is no extraneous information.

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 absence of an output schema, the description should explain what the tool returns (e.g., a list of warnings/alarms). It does not. Additionally, it does not elaborate on prerequisites or the relationship between parameters, leaving gaps for a tool with 4 parameters.

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 coverage is 100% with descriptions for each parameter. The description adds minimal extra meaning beyond mentioning 'historical time ranges', which is already implied by the start and end parameter descriptions. No enhancement for the siteId or instance parameters.

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 identifies the tool as retrieving VE.Bus system warnings and alarms for troubleshooting, specifying the resource and purpose. However, it does not differentiate from sibling tools like vrm_get_inverter_charger_warnings_alarms, which may have overlapping functionality.

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 mentions 'for troubleshooting' and 'supports historical time ranges', providing context on when to use the tool. However, it does not give explicit guidance on when not to use it or suggest alternative tools for similar tasks.

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