compare_tool_databases

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the qualifier 'semantically' but does not explain what that entails or any other behavioral traits (e.g., how comparison results are presented). It does not contradict the annotations.

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, well-structured sentence that states the core purpose without fluff. It is front-loaded with the action and object, though it is so terse that it skips essential details. It earns its place but could be more informative without losing conciseness.

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?

Although an output schema exists, the description omits critical information: parameter formats, what 'semantically' means, and any usage context. An agent cannot reliably call this tool without additional clarification, making the definition incomplete for its purpose.

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 0% – the parameters 'left' and 'right' have empty schemas with no types or descriptions. The description implies they are the two tool database snapshots but gives no format, structure, or how to provide them (e.g., file paths, objects). This fails to compensate for the schema's lack of detail.

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 verb 'compare' and the resource 'tool database snapshots', which distinguishes it from sibling tools like compare_toolpaths or compare_nc_files. The qualifier 'semantically' adds nuance but is not fully explained. Overall, the purpose is unambiguous.

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 the many sibling comparison tools (e.g., compare_toolpaths, compare_nc_files). No mention of prerequisites, input formats, or exclusions, leaving the agent to guess the appropriate context.

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