compare_os_versions

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

No annotations provided; description does not explicitly state whether the tool is read-only or has side effects. However, the mode enum (behavior_diff, validity, deprecation, new_capabilities) suggests observational behavior. Partial transparency but not fully explicit.

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?

Single sentence that is front-loaded and concise. Every word adds value without redundancy.

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?

Description covers the core action but lacks details on output format, return values, or behavior for each mode. Given no output schema, more context on expected results would improve usability.

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 covers all parameters with descriptions and enums. The tool description reinforces the purpose but adds little extra meaning beyond what the schema provides. Baseline 3 due to high coverage.

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?

Description clearly states the tool compares LOL technique behavior across OS versions, listing specific aspects: binary behavior differences, technique validity, deprecation tracking, new capabilities. It distinguishes from siblings like compare_platforms by focusing on OS version comparison for techniques.

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?

Description implies usage context (comparing across OS versions) but provides no explicit guidance on when to use vs alternatives or when not to use. No exclusions or alternative tool mentions.

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