estimate_music_cost

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

No annotations provided. The description mentions a specific cost ($0.68) but does not disclose whether it's a simple fixed price or based on input parameters (e.g., duration). No mention of side effects or limitations.

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 concise sentences, front-loaded with purpose. No wasted words, but could be slightly more structured (e.g., separating cost 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?

Adequate for a simple estimate tool with two parameters. However, lacks output format description (e.g., what the estimate looks like) and does not clarify if cost is per second or total, despite having a duration parameter.

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%, but description adds value by explaining the audio_format enum: 'WAV adds +$0.10'. This provides practical meaning beyond the schema itself.

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 estimates music generation cost with verb 'Estimate' and resource 'music generation'. However, it does not distinguish from sibling tools like 'estimate_cost' or 'estimate_video_cost', so not a 5.

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?

No guidance on when to use this tool versus alternatives. Lacks context for usage scenarios or when not to use.

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