Compare Software Versions

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

With no annotations, the description must disclose behavioral traits. It only states what the tool does, without mentioning that it is read-only, potential performance implications, or any prerequisites. The description lacks transparency about side effects or limitations.

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 concise with two sentences. The first sentence front-loads the main purpose, and the second elaborates. It is well-structured for a brief description, though it could potentially include more details without being verbose.

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 7 parameters and no output schema, the description covers the core functionality but lacks details on the output format, return structure, or any limitations. It is adequate for a simple tool but not fully comprehensive for the complexity.

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%, so baseline is 3. The description mentions 'bugs, CVEs, and recommendations' which aligns with parameters, but does not add significant meaning beyond the schema descriptions. No extra clarification or context added for parameters.

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 tool compares two software versions on bugs, CVEs, and recommendations. It uses a specific verb 'compare' and identifies the resources. However, it does not explicitly distinguish from sibling tools like comprehensive_analysis, but it is clearly a comparison tool.

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. The description does not specify prerequisites, exclusions, or context where this tool is preferred over siblings like smart_search_strategy or multi_severity_search.

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