backup_config

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

No annotations are provided, so the description carries full burden. It discloses that the tool fetches and saves a timestamped copy, which is non-destructive, but does not mention permissions, side effects, or error behavior. It adds some value but lacks depth.

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 short and front-loaded with the key action. Every sentence adds value: purpose, what it does, return values, and parameter explanation. No wasted words.

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 has an output schema (presumably documenting return structure), the description covers the main behavioral aspects. However, it lacks details on failure modes, device accessibility, or prerequisites, which would improve completeness.

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 0%, but the description adds meaning to the 'device' parameter by specifying it is 'as defined in devices.yaml'. This clarifies the source of device names, which is not in the schema. It compensates for the lack of schema documentation.

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's main action ('Backup the running configuration') and specifies the resource (network device) and outcome (saves timestamped copy locally). This distinguishes it from sibling tools like 'compare_configs' or 'show_routing_table'.

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 for backing up device configurations but does not explicitly state when to use this over alternatives like 'compare_configs' or when not to use it. The context is clear from the purpose, so it's adequate but could be improved.

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