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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action 'compare' but doesn't explain what the comparison entails (e.g., diff output, side-by-side view, change highlights), whether it's read-only or has side effects, or any performance/rate limit considerations. For a tool with no annotations, this leaves significant behavioral gaps.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It's front-loaded with the core action and resources, making it easy to parse. Every word earns its place, achieving optimal conciseness.

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 tool has one parameter with full schema coverage and no output schema, the description is minimally adequate but incomplete. It doesn't explain what the comparison output looks like or behavioral aspects, which are important for a comparison tool. With no annotations and simple schema, the description should do more to cover usage context and results.

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 description mentions no parameters, while the input schema has one parameter 'focus' with 100% schema description coverage. The schema already fully documents the parameter with enum values and default, so the description adds no additional semantic meaning. This meets the baseline of 3 for high schema coverage without description compensation.

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 'compare' and the resources 'latest and trunk versions of EDSS documentation', making the purpose immediately understandable. However, it doesn't distinguish this tool from its siblings like 'get_edss_documentation' or 'download_edss_documentation', which might also involve documentation retrieval. The purpose is clear but lacks sibling differentiation.

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 provides no guidance on when to use this tool versus alternatives. With siblings like 'analyze_edss_api_endpoints' and 'search_edss_documentation', there's no indication of whether this tool is for version comparison specifically or overlaps with other documentation tools. No explicit when/when-not or alternative recommendations are included.

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