Generate Controlled Voice

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

No annotations are provided, so description carries burden. It discloses pricing ($0.003/$0.006 per character range), implying cost awareness. However, it does not mention error behavior, idempotency, or other side effects beyond generation.

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?

Two sentences: first states core purpose, second provides usage guidance and cost. No redundant phrases, front-loaded with essential info.

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 no output schema, description does not explain return format (WAV assumed). It provides pricing and character limit but lacks details on parameter bounds handling or error scenarios. Adequate for simple generation tool but could be more thorough.

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% with descriptions for all 5 parameters. Description adds minimal extra meaning beyond 'granular controls' (speed/steps) and pricing limits (text length). Baseline is adequate but not enhanced.

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 specifies verb 'Generate WAV speech' and resource 'granular controls for speed and quality'. It suggests use case for controlled delivery, which somewhat distinguishes from siblings like generate_standard_voice, but does not explicitly name alternatives or highlight unique differentiators.

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 includes use condition ('when an agent needs faster, slower, clearer...') but lacks explicit when-not-to-use or alternative tool mentions. It provides context but no exclusions.

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