perfmon_add_alerts

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

With no annotations, the description carries the full burden of behavioral disclosure. It communicates an additive action but does not explain whether alerts are merged, overwritten, idempotent, or require existing perfmon configuration. This is a minimal statement of operation rather than a transparent description of behavior.

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 succinct and front-loaded, with no filler or redundant phrasing. It is appropriately compact for a small tool, though it would benefit from expansion in other dimensions.

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 two parameters, no output schema, and no annotations, the description is too sparse to be fully actionable. It omits the target system, the expected configuration, the effect on existing alerts, and the role of api_key, leaving an agent to guess important invocation details.

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 description coverage is only 50%: directory is described as 'Project directory', but api_key has no schema description and the tool description does not clarify how either parameter is used. The description adds no meaning beyond the schema and leaves the role of api_key and the contents of directory unexplained.

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 states a clear verb ('Add') and a specific resource ('performance threshold alerts'), so the core intent is unambiguous. However, it does not differentiate from sibling tools such as monitor_create_alerts or grafana_add_alerts beyond the perfmon context implied by the name.

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?

No guidance is provided about when to use this tool versus alternatives, nor are any prerequisites or excluded scenarios mentioned. A tool called perfmon_add_alerts could be chosen correctly by name alone, but an agent has no support for deciding between this and related alert-creation tools.

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