compare_versions

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

No annotations are provided, so the description carries the full burden. It doesn't disclose whether the operation is read-only, what the output format is, or any side effects. The parameter 'compare_api' hints at an API diff but the description itself gives no behavioral details.

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, concise sentence that is front-loaded with the main action. It wastes no words and is easy to parse.

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?

The tool is simple and the parameters are clear, but the description doesn't mention what the comparison result looks like (e.g., diff, report, boolean). Given there is no output schema, this missing information leaves a gap in 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 coverage is 100% and each parameter has a brief description. The descriptions are self-explanatory for group_id, artifact_id, version1, and version2. However, the description adds no extra semantic value beyond the schema, so it stays at the baseline.

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 ('Compare') and the resource ('different versions of the same Maven artifact'), which is specific and unambiguous. It distinguishes the tool from siblings that list versions or analyze structures, though it doesn't explicitly name alternatives.

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: comparing two versions of an artifact. It doesn't explicitly state when not to use it, but the context is clear enough for a simple comparison tool. It could mention that it's for side-by-side version comparison, but the required parameters (version1, version2) make this obvious.

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