clab_devices_yaml

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

No annotations are provided, so the description must fully disclose behavior. It mentions creating a YAML file connecting to management IPs, but does not state side effects (e.g., overwriting, file location) or requirements (e.g., permissions, existing lab).

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 concise, with a front-loaded main sentence and a brief Args block. No redundant phrases; it efficiently conveys the tool's purpose and parameter.

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 tool's simplicity (one optional parameter) and the presence of an output schema, the description provides the core purpose. However, it lacks details on output behavior (e.g., whether the YAML is returned or saved) and does not compensate for missing annotations.

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 description includes an Args block explaining the single parameter 'scenario' as the lab scenario to generate for, adding meaning beyond the schema's minimal type and default.

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 tool generates a devices.yaml for a Containerlab lab, connecting to management IPs for MCP-Telecom use. It distinguishes from siblings like clab_generate by specifying the exact file type, though not explicitly differentiating.

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 use after containerlab deployment but lacks explicit guidance on when to use this tool vs alternatives like clab_generate. No exclusions or prerequisites are provided.

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