GetClassVersionDiff

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

The description marks the tool as read-only with '[read-only]' and states it computes a unified diff, which is useful behavioral context beyond the schema. No annotations exist, so the description carries the burden; missing details like authorization or error handling prevent a perfect score.

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 front-loads the read-only behavior and uses precise language. 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?

Given the absence of an output schema and no nested objects, the description adequately covers purpose and parameter origin. It explains the diff format (unified diff) but could mention prerequisites or response structure for 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% with descriptions, providing baseline 3. The description adds value by specifying that content_uris come from GetClassVersions entries, which directly informs parameter usage and source.

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 'Compute', the resource 'unified diff between two ABAP class versions', and the method 'by their content_uris', distinguishing it from sibling version-listing tools like GetClassVersions and other object-specific diff tools.

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 explicitly ties parameter values to GetClassVersions entries, guiding when to use this tool. However, it does not mention when not to use it or contrast with other version comparison tools, though the sibling list provides implicit differentiation.

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