generate_persona

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

With no annotations, description must disclose behavioral traits. It mentions 'reusable music character' and the prerequisite, but does not state side effects, auth needs, or what happens to the existing track. Minimal insight beyond basic action.

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 – two sentences. Front-loaded with 'NEW' to indicate freshness. No fluff; every word earns its place.

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?

Description is functional but omits broader context: what a Suno Persona is, how to use it post-creation, or what the API returns. Given 7 parameters and no output schema, more context would aid completeness.

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% (all parameters described). Description adds no extra meaning beyond the schema, e.g., the prerequisite is already in taskId description. Baseline 3 is appropriate.

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?

Explicitly states it creates a Suno Persona from an existing Suno track, with specific verb and resource. Clearly distinguishes from sibling generation tools like generate_music or cover_audio by focusing on persona creation.

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?

Provides a clear prerequisite (taskId from V3.6+ generation) but lacks guidance on when to use persona creation versus alternatives like cover_audio or generate_music. No explicit when-not or comparison to siblings.

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