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

Annotations establish the mutation profile (non-readonly, non-idempotent, non-destructive), and the description adds real behavioral context beyond them: the product lands in the user's manual feed, a feed-{id} is returned, and image URLs are re-hosted on oriiion storage. The storage side effect is a genuinely useful disclosure not captured by annotations.

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, front-loaded sentences with no filler; the core action comes first, followed by the actionable return value and one notable side effect.

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?

With no output schema, the description usefully explains the return value (feed-{id}) and its immediate reuse with generate_from_product, plus the storage side effect. It is complete enough to invoke correctly, though it could mention whether re-hosting is required or optional.

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 100%, so the schema already documents title, imageUrls, and description. The description only adds the re-hosting behavior for image URLs, which is marginal over the schema's baseline documentation.

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+resource ('Create a new product in oriiion') and clarifies the destination scope ('added to the user's manual product feed'). This distinguishes it from create_product_video and from feed-generation tools, though it doesn't explicitly name a sibling to avoid.

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?

It implies downstream usage by noting the returned feed-{id} can be used with generate_from_product, which helps position it in a workflow. However, it gives no explicit when-to-use/when-not guidance or comparison against list_products or other creation tools.

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