list_networks

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

As a listing operation, it implies read-only behavior with no side effects. However, the description does not explicitly state that it does not modify any resources or mention any permissions or rate limits. The lack of annotations places the full burden on the description, which is mostly adequate.

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 a single, clear sentence with no superfluous words. It directly conveys the tool's purpose and output content.

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 listing tool, the description is complete. It states what is listed (all Docker networks) and what information is provided (driver and scope). No additional context is necessary for an agent to invoke it correctly.

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 no parameters, so the empty input schema fully covers all possible inputs. The description does not need to elaborate on parameter details because there are none.

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 specifies the action ('Lists') and the resource ('all Docker networks') along with the relevant attributes ('driver and scope'). This distinguishes it from sibling tools like 'create_network' or 'list_containers'.

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 does not explicitly mention when to use this tool versus alternatives. While the purpose is obvious, it lacks direct guidance such as 'Use this to view network details, not to create or modify them.'

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