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

With no annotations provided, the description carries the full burden and does so thoroughly. It discloses that each model is reviewed individually, the pack is approved as a whole, nothing goes live until approval, and the user is emailed the outcome—providing rich behavioral context beyond the schema.

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 four sentences with no filler, front-loading the core action before detailing the workflow. Every sentence adds value, from the count constraint to the approval process to the email notification.

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?

The description covers prerequisites, the approval flow, publication behavior, and notification. For a tool with no output schema, it provides sufficient context for an agent to invoke it correctly, including the state of uploads (processing, pending, published).

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%, so the description must compensate. It explains the assets parameter (slugs of the user's own uploads, 2–50) but does not elaborate on title, summary, or description. The schema itself marks these as required and constrains them, but the description adds limited semantic value beyond the assets field.

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 a specific action: grouping the user's own uploads into a pack proposal, with explicit constraints on count (2–50). It distinguishes itself from sibling upload tools by positioning as the pack-proposal step after uploading, making its purpose unambiguous.

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 explicitly instructs the agent to upload models first via finalize_upload or submit_asset_from_url, then pass slugs. This establishes a clear workflow and implies this tool is not for individual uploads. It stops short of explicitly stating when not to use it, but the guidance is strong.

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