Confirm and link an uploaded digital file

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true. The description adds genuinely useful context beyond them with the 100 req/10 sec per shop rate limit and the storage-prerequisite constraint, but it never explains what destruction/re-linking means or what happens on a repeat call despite idempotentHint=false.

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?

Two sentences plus a rate-limit note; the operational constraint and purpose are front-loaded with zero filler.

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 7-parameter mutation with a nested payload, full schema coverage and annotations carrying the safety profile, the description covers the workflow position and rate limit adequately. It is slightly thin on post-call behavior and duplicate/retry semantics, but an output schema is absent and nothing essential to invocation is missing.

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% and every parameter (account, confirm, fileUrl, payload, fileName, product_id, payload_file) is already documented in the schema. The description adds no parameter-level meaning such as required combinations or how confirm relates to payload, so the baseline 3 applies.

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 states a specific verb and resource: 'link the file to the product' via a confirmation endpoint, which is distinct from the sibling request_digital_file_upload_url and upload_file. However, it never explicitly names which sibling this is not, so the differentiation is inferred from the workflow rather than stated.

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 gives clear situational guidance: call this 'after uploading a file to the presigned URL' and only when 'the file must exist in storage'. That is a usable precondition, but it offers no exclusion or alternative path (e.g., what to do if the upload failed or the URL expired).

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