generate_blob_set

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

With no annotations and no output schema, the description carries the full burden of behavioral disclosure. It only states that multiple blobs are generated and scattered, but it does not disclose the output format, whether the result is deterministic via seed, how randomness works, or any side effects. This is a significant gap for a generative tool.

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 two tight sentences with no filler. The main action is front-loaded, followed by practical use cases, which makes it easy to scan and understand quickly.

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 (10 parameters), lack of annotations, and lack of an output schema, the description is too sparse. It does not mention the return format, how to choose this over sibling tools, or important behavioral details like determinism and randomness, leaving an agent to make assumptions.

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 description coverage is 100%, so the structured schema already documents all 10 parameters. The description adds no extra parameter-level meaning, which is acceptable because the baseline is 3 when the schema handles the heavy lifting.

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 states a specific verb and resource: 'Generate multiple blobs scattered on a canvas.' It clearly differentiates from siblings like generate_blob by emphasizing multiple blobs and from generate_blob_path by focusing on a composed set rather than a single path.

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 usage context: 'Useful for backgrounds, hero sections, and decorative compositions.' However, it does not explicitly mention when not to use this tool or directly compare it with sibling tools, so it stops short of a full when/when-not guide.

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