generate_character_build

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool 'generates' an 'optimized' build, implying a creation/calculation operation, but doesn't disclose critical traits like whether it's deterministic, requires external data, has rate limits, or what the output format looks like. For a tool with 9 parameters and no output schema, this is a significant gap in transparency.

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 front-loads the core purpose without unnecessary words. It directly states what the tool does ('Generate an optimized character build') and the key components involved, making it easy to parse and understand quickly.

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's complexity (9 parameters, no annotations, no output schema), the description is incomplete. It doesn't explain what 'optimized' means, how the build is generated, what the output includes, or any behavioral constraints. For a generative tool with significant input options, more context is needed 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?

The schema description coverage is 100%, meaning all parameters are documented in the schema itself. The description adds no additional parameter semantics beyond implying optimization across 'race, class, background, and feats,' which aligns with some parameters but doesn't provide extra details like syntax or interaction rules. This meets the baseline for high schema 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?

The description clearly states the tool's purpose: 'Generate an optimized character build combining race, class, background, and feats.' It specifies the verb 'generate' and the resource 'character build' with key components. However, it doesn't explicitly differentiate from sibling tools like 'get_build_recommendations' or 'compare_character_builds,' which prevents a perfect score.

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 sibling tools like 'get_build_recommendations' or 'compare_character_builds,' nor does it specify prerequisites, constraints, or ideal scenarios for its use. This lack of contextual direction limits the agent's ability to choose appropriately.

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