guide_compare_versions

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

With no annotations provided, the description carries full burden but only states the action. It does not disclose whether the tool is read-only, requires specific permissions, has rate limits, or what side effects (if any) occur. The description is purely functional without behavioral context.

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 efficiently conveys the core function. However, it could be improved by structuring the explanation to explicitly mention the key parameters (guide, canonical_id, version_a, version_b) for clarity.

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 4 parameters, no annotations, and presence of an output schema (which reduces the need to describe return values), the description still fails to provide essential context like what constitutes a 'guide' or how versions are specified. The tool is underspecified for reliable agent use.

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 description coverage is 0%, yet the description does not elaborate on any parameter meanings. It implies the parameters correspond to a test case and two versions but omits details like expected formats or relationships. The agent must infer parameter semantics solely from names, which is insufficient for correct invocation.

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 specifies a clear verb 'Compare' and a specific resource: 'test case's title/objectives/sections/source across two compiled guide versions'. It uniquely identifies a comparison operation, clearly distinguishing it from sibling tools like guide_search or guide_browse_category.

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 guidance is provided on when to use this tool versus alternatives like guide_get_test or guide_list_tests. There is no mention of prerequisites, such as needing to identify a test case's canonical_id or versions beforehand, which limits the agent's ability to decide appropriately.

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