list_events

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'No parameters required' and that it wraps an API, but does not disclose the return format, pagination, potential errors, or whether it's read-only. For a simple list operation, this is minimal coverage.

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?

Two short sentences with no filler. The purpose is front-loaded, the wrapper note adds context, and the parameter note is useful. Every sentence earns its place.

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?

For a simple no-parameter list tool, the description covers the essentials: what it lists and that no parameters are needed. However, it does not describe the response format (e.g., array of event definitions), and with no output schema, an agent might not know what to expect. This is a minor gap but not fatal for such a straightforward tool.

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?

The tool has zero parameters and the schema is empty. The description explicitly states 'No parameters required', which confirms the parameter behavior. With 0 parameters, the baseline is 4, and the description adequately covers it.

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 states the verb 'Lists' and the resource 'event types/definitions known to the NetBox system', and even names the underlying API wrapper (NBAPI ListEvents). This is unambiguous and distinguishes it from sibling tools like get_event_history, which deal with history rather than definitions.

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 implies usage (when you need to list event definitions) but does not explicitly state when not to use it or point to alternatives. Since there are siblings like get_event_history, the description could have clarified that this tool is for definitions, not history. However, the wording 'event types/definitions' is fairly clear, so it gets a mid score.

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