seedream_sequential_generation

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

The description indicates image generation but does not disclose additional behavioral traits beyond annotations (readOnlyHint=false, destructiveHint=false). No mention of auth, rate limits, model-specific constraints, or output format. Schema provides some parameter details but description lacks behavioral context.

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 a single sentence (27 characters) that immediately states the core purpose and examples. No superfluous text; it is optimally concise and front-loaded.

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 (many parameters, no output schema, minimal annotations), the description is adequate but leaves out important context like the sequential nature, response format, and model-specific limitations. Schema compensates partially, but overall completeness is average.

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 tool description does not explain any parameters; the input schema has full descriptions for each parameter (high coverage). Thus the description adds no value beyond what's already in the schema, justifying the baseline score of 3.

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 generates a set of related images (group image output) from text and optional images, with examples like comic panels and brand visuals. It distinctly differs from sibling tools (seedream_browse_images, seedream_image_to_image, etc.) by focusing on sequential generation of multiple related images.

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 implies the tool is for generating groups of related images but does not explicitly state when to use it over alternatives or provide any exclusion criteria. No guidance on prerequisites or when not to use.

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