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

The description adds meaningful behavioral context beyond the readOnlyHint annotation by mentioning no-fabrication placeholders, analyzer provenance, MASK, brand status, and approval requirements. It does not contradict the annotation because generating a 'draft' suggests an in-memory result rather than a persistent change.

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 front-loaded sentence with no filler, and the key action is stated immediately. However, the dense jargon such as MASK, analyzer provenance, and approval requirements is not explained, which slightly reduces overall clarity.

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 a 17-parameter tool with no parameter descriptions, this description is far too sparse. It omits when to generate versus refine or save, how format/lane/variant settings interact, and what MASK or approval requirements actually mean. The output schema covers return values, but the invocation and selection context remains incomplete.

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 17 parameters and 0% schema description coverage, the description needed to compensate heavily but does not. It vaguely signals tenant scoping and artifact type, but terms like MASK, analyzer provenance, and approval requirements do not map to any schema property, leaving the agent without useful parameter-level guidance.

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 action ('Generate') and the resource ('governed, tenant-scoped artifact draft'), which distinguishes it from siblings like artifact_save, artifact_refine, and artifact_export. The word 'draft' helps differentiate it from persistence-oriented tools, though no alternative is named explicitly.

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?

There is no guidance on when to use this tool versus artifact_refine, artifact_save, or other generation-related siblings. The description implies a draft-generation use case but never states when it should be preferred or what to do after generation.

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