Configure pre-generation moderation

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

With no annotations provided, the description carries full responsibility for disclosing behavior. It covers the screening timing, rejection of disallowed prompts, persistence to config.json, immediate effect, and the null-unchanged semantics, which is comprehensive and goes well beyond the schema.

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 concise and well-structured, with four sentences each adding unique value: purpose, behavior, null semantics, persistence, and disabling. There is no redundancy or fluff.

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?

The description thoroughly covers the tool's behavior and effects, and an output schema exists to document return values. However, it leaves the meanings of key parameters undefined, which is a significant gap for a configuration tool with no schema descriptions. This prevents full 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?

The schema has 0% description coverage for its five parameters, so the description must compensate. It only explains that null arguments are unchanged and that enabled=false turns moderation off, leaving model, prompt, api_key, and api_base_url unexplained. This is insufficient for an agent to correctly set these parameters.

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's function: configuring a moderation gate for pre-generation screening. It uses a specific verb 'Configure' and identifies the resource as the moderation gate, effectively distinguishing it from sibling tools like set_config and generate_image.

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 description provides clear context for when to use this tool—to configure moderation screening before image API calls—and explains how to disable it. However, it does not explicitly mention alternatives or exclusion criteria, though the focus on moderation makes the use case fairly unambiguous.

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