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

The annotations already declare non-readOnly, idempotent, non-destructive, open-world behavior, so the bar is lower; the description still adds real value by disclosing that it consumes paid credits ('its credit caps'), produces only logo concepts, and does not publish.

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?

Three short sentences, front-loaded with the action and the cost implication, then the non-publishing caveat and the type constraint. No filler, though the placement of the type constraint at the end is slightly suboptimal.

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?

An output schema exists so return values need not be described, and annotations cover the safety profile. The remaining gap is significant: four required parameters with zero schema documentation and no description-level explanation of their meaning or expected values.

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?

Schema description coverage is 0% for all four parameters, so the schema carries no per-field meaning and the description must compensate. It does not name or explain brandId, revision, automationId, or idempotencyKey, leaving the agent to infer the idempotency key and revision semantics from names alone.

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?

States a specific verb (generate) and resource (paid review sample from a saved recipe), plus a scoping qualifier that the saved automation type must match. It is distinguishable from the wider generate_*_sample family by the 'logo concepts' framing, though it never names a specific sibling.

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?

Provides one precondition ('the saved automation type must match this tool') and a key exclusion ('does not publish'), which implies when to use it. However, it never contrasts against the related prepare_/activate_/update_logo_maker_automation tools, so the agent must infer the branch point.

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