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

No annotations provided, so description bears full burden. It only provides input formatting tips ('no +', 'public URL'), but does not disclose behavioral traits like required permissions, size limits, supported formats, or whether the audio is sent as a voice note.

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: the first states the action, the second gives parameter hints. Front-loaded and efficient, but could include more detail without being verbose.

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 output schema exists (not shown), description should mention return values. It also lacks differentiation from many sibling send tools and misses constraints like file size or format. Incomplete for practical 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?

With 0% schema description coverage, the description adds value by hinting at formatting constraints (phone without '+', audio_url must be public URL). However, it does not specify expected formats or country code requirements, leaving gaps.

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 action 'Send audio via WhatsApp' and implies the resource. It distinguishes from sibling send tools by specifying audio, though it could be more explicit about the type of audio (e.g., voice note).

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 other WhatsApp send tools (e.g., send_text, send_image). The description only implies via context, but does not explicitly state prerequisites or alternatives.

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