diff_snapshots

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 does not mention whether the operation is read-only, whether it requires special permissions, how output is formatted, or if there are any side effects. The phrase 'Unified diff' implies a comparison, but no additional behavioral context is given.

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 that front-loads the core action. It is appropriately concise with no wasted words, though it could benefit from additional detail while remaining succinct.

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 that the tool takes three required parameters and has an output schema, the description is incomplete. It does not explain how to get valid snapshot IDs, what constitutes a 'device' in this context, or any nuances of the diff output. While the output schema may document the return structure, usage context is missing, making it minimally viable but with clear gaps.

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 schema description coverage is 0%, so the description must compensate by explaining the parameters. It only says 'two config snapshots of a device,' which loosely maps to old_id, new_id, and device, but does not clarify expected formats, how to obtain snapshot IDs, or what the 'device' identifier refers to. The description adds minimal value beyond the schema's parameter names.

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 action ('Unified diff') and the resource ('two config snapshots of a device'). It is specific enough to convey what the tool does, though it does not explicitly distinguish it from sibling tools that handle configurations or snapshots, such as list_snapshots or export_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?

There is no guidance on when to use this tool versus alternatives, nor does it mention prerequisites such as obtaining snapshot IDs or device identifiers. The description simply states what it does without context on typical use cases or exclusions.

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