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

Discloses pricing ($0.08/$0.04) which is critical for paid models, but missing return value info, file persistence details, and rate limits (no annotations provided to cover these).

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?

Extremely concise and front-loaded; every sentence earns its place, though brevity comes at cost of missing behavioral details.

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?

Critical gap: no output schema exists and description fails to explain what is returned (file path, URL, binary data?) or auto_play behavior.

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 75% and adequately describes parameters; description adds minimal semantic value beyond schema except reinforcing the pricing model.

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?

Clearly states it generates songs/loops/segments and distinguishes from siblings (generate_sfx, generate_voice, generate_soundscape) by specifying 'melodic content, rhythm, and structured compositions'.

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?

'Best for melodic content...' provides positive guidance for selection, though lacks explicit 'when not to use' or direct sibling comparisons.

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