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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. The verb 'Compare' inherently suggests a non-mutating read operation, and the description adds the comparison key ('by updated_at'), which clarifies part of the behavior. However, it does not explicitly state that the operation is read-only, nor does it mention return format or error behavior, leaving some ambiguity.

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 of 12 words. It is front-loaded with the action verb 'Compare', immediately conveys the resources involved, and contains no redundant information. Every word earns its place.

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?

Tool simplicity and full schema coverage make the description largely adequate. However, since there is no output schema, the description does not explain what the comparison returns (e.g., a diff, a boolean, or a report). While the core purpose is clear, this missing return value information prevents full 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?

The input schema provides 100% coverage with descriptions for all three parameters, achieving the baseline of 3. The description adds value by explaining that the comparison is driven by the 'git_exported_at' timestamp ('by updated_at'), which clarifies the role of that parameter in the comparison context, going beyond the schema description.

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 uses the specific verb 'Compare' and clearly identifies both resources: a GIMS component and its Git version. The qualifier '(by updated_at)' adds a distinguishing detail not present in sibling tools, which are primarily CRUD operations. This makes the tool's purpose distinct and 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?

No explicit when/when-not or alternative tools are mentioned. The intended usage is implied by the verb 'Compare', and the sibling list contains no similar comparison tool, so it is clear this is the tool for comparing versions. However, the description does not provide explicit guidance on prerequisites or scenarios where this tool should be avoided.

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