compare_character_builds

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 'generate and compare', implying a creation and analysis operation, but doesn't disclose whether this is a read-only or mutative process, what the output format looks like, or any performance considerations like rate limits. The description is too vague to guide the agent on behavioral expectations beyond the basic action.

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: 'Generate and compare multiple character builds with different options'. It's front-loaded with the core action and resource, with zero wasted words. Every part of the sentence contributes directly to understanding the tool's purpose.

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 complexity (3 parameters, no annotations, no output schema, and 33% schema coverage), the description is incomplete. It doesn't explain what 'compare' entails in terms of output, how builds are generated, or the role of parameters like 'campaign_type'. For a tool with multiple inputs and no structured output documentation, the description should provide more context to guide effective 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 33% (only 'build_options' has a description), so the description must compensate. It mentions 'different options' which loosely relates to 'build_options', but doesn't explain the semantics of 'campaign_type' or 'focus_level'. The description adds minimal value beyond the schema, failing to fully address the coverage gap. Baseline 3 is appropriate as it doesn't adequately compensate.

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's purpose: 'Generate and compare multiple character builds with different options'. It specifies the verb 'generate and compare' and the resource 'character builds', which is distinct from sibling tools like 'generate_character_build' (singular) or 'get_build_recommendations' (retrieval). However, it doesn't explicitly differentiate from 'generate_character_build' beyond the plural 'multiple', leaving some ambiguity.

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. It doesn't mention when to choose this over 'generate_character_build' (singular) or 'get_build_recommendations', nor does it specify prerequisites or exclusions. The lack of context makes it unclear how this tool fits into the workflow with its siblings.

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