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

Annotations already signal this is a write (readOnlyHint=false), and the description adds meaningful behavioral detail: the upload is product-scoped, the resulting version is immutable, and the file is read from a local path. It stops short of describing failure modes or preconditions like authentication, but it adds value beyond the 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?

The description is a single dense sentence with no filler: it front-loads the explicit path requirement, then the transfer mechanism, then the commit outcome. Every clause adds information an agent needs.

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 workflow is clear, but there is no output schema and the description omits return value, version-conflict behavior, and error/precondition details. This is adequate for a straightforward upload/commit call, yet it leaves meaningful gaps for autonomous selection and invocation.

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 only 25% schema description coverage, the description compensates: packPath is the explicit local .taip path, version is the immutable higher version to commit, and productId is the product scope of the private upload contract. Only the optional changelog parameter is left to inference from its name.

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 names a specific resource (an explicit local .taip path) and a precise operation: transfer through the private upload contract and commit an immutable higher version. This clearly separates the tool from siblings like upload_ai_pack_image, update_ai_pack_draft, and publish_ai_pack.

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 gives a clear invocation context: use it when an explicit local .taip pack exists and a higher immutable version should be committed. It does not name alternatives or explicitly state when-not-to-use, but the scoping is strong enough that an agent can identify the intended case.

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