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

Beyond the annotations, it explains that omitted fields remain unchanged, no job is started, style changes have an environment requirement, and there is no guaranteed undo. 'Reuse operation_id on retries' also adds relevant idempotency guidance that supports the idempotentHint.

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?

The description is dense but well ordered: purpose, update semantics, prerequisites, behavioral constraints, and retry/rollback caveats. Each sentence adds distinct information without repeating schema or annotation content.

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 tool's complexity and lack of an output schema, it covers the key operational context: prerequisites, side effects, retry behavior, and no-undo warning. It does not explain the return value or clarify whether explicit nulls behave like omitted fields, but the essential usage requirements are present.

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 and 15 parameters, the description adds broad meaning by categorizing them as 'Generate settings' and explaining omission semantics. However, it does not define or clarify many individual fields (e.g., use_inpaint, resolution_multiplier, batch_count), leaving a gap for parameter-level understanding despite the warning about root prompts/strength/seed.

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 opens with a specific verb and resource: 'Persist specified Generate settings' and immediately distinguishes itself from generation tools with 'without starting a job.' This makes the tool's role clear even among the large sibling list.

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?

It gives clear conditions: requires pinned add-on and active document, style changes need local backend, and reuse operation_id on retries. It implies when to use it (persist settings rather than launch generation), though it does not explicitly name alternatives or state when not to use sibling tools.

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