compare_configs

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

No annotations are provided, so the description must fully convey behavior. It states it performs a diff and highlights changes, but does not mention that it is read-only (no side effects), what happens if the backup file is missing, or any authorization requirements. The description is adequate but leaves some uncertainty.

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 and well-structured: a clear title sentence, a brief summary of the operation, and a parameter list. It is front-loaded with the most important information and contains no unnecessary 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?

For a simple comparison tool with a good output schema, the description covers purpose and parameters adequately. However, it lacks usage guidelines and does not explicitly state that the operation is non-destructive. Given the tool's simplicity, it is mostly complete but could be slightly more thorough.

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 input schema has 0% coverage (no descriptions for parameters). The description compensates fully by explaining each parameter: 'device: Name of the device as defined in devices.yaml' and 'backup_file: Path to the backup file to compare against'. This adds essential meaning beyond the schema.

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 explicitly states 'Compare the current running config with a previous backup' and further details that it performs a diff between live running config and a saved backup file, highlighting additions and removals. This clearly distinguishes it from sibling tools like 'compare_devices' or 'backup_config'.

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 purpose is very clear, implying when to use it (to compare running config with a backup). However, it does not explicitly state when not to use it or mention alternatives, such as using 'compare_devices' for inter-device comparisons. This is a minor gap.

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