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

Annotations already establish this is a non-read-only, non-destructive operation, so the main added value is the disclosure that the work is queued and asynchronous. It does not say what happens to any existing analysis, whether duplicate triggers are allowed, or how completion is surfaced.

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?

A single front-loaded sentence with no filler and the async qualifier placed where it's immediately visible. It is terse to the point of omitting useful detail, but nothing in it is wasted.

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?

For an async job trigger with no output schema, the definition covers what the job is and that it is queued, but not how the caller learns the result or when re-triggering is appropriate. That's the key operational gap for this kind of tool.

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 description coverage is 100% and all three parameters carry descriptions, so the schema already documents id, platforms, and include_custom_samples. The description adds nothing about defaults, e.g. whether omitting platforms means all platforms.

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 names a specific verb and resource: triggering AI analysis of a persona's writing style. That distinguishes it from read-only siblings like get_persona and from discard_persona_analysis, though it doesn't explicitly name the boundary with those siblings.

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?

The '(queued async)' note implies the caller should not expect synchronous results and hints that a separate status/retrieval path exists, but it never states when to use this versus alternatives such as discard_persona_analysis or re-running on an already-analyzed persona.

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