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

Beyond the annotations it discloses real behavior: integrity checks performed (size, MIME, SHA-256), atomic commit of asset creation plus completion, and that retries return the same asset rather than duplicates. The idempotency claim largely restates idempotentHint=true, and the 'rights are confirmed before generation' sentence is a precondition with no stated failure mode. Still a substantive addition over the structured fields.

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?

Front-loaded with the verification-and-import pipeline, then the retry contract. Dense and mostly waste-free. The literal 'Arguments: {"path": {"upload_id": ...}}' block duplicates the input schema and is the one part that does not earn its place.

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?

No output schema exists, and the description does state what comes back (the same asset, no duplicates), which is the key return-value fact. Safety and idempotency are covered by annotations plus the text. What is missing is the failure surface — what happens on a hash mismatch or when rights are not confirmed — which matters for a mutating, verification-heavy tool.

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% and the single parameter is a nested object, so the description must carry the load. It does clarify that upload_id is 'the upload_id of the ticket', which is genuinely useful, and the trailing Arguments block mirrors the shape. But it never says how to obtain the ticket id or what the id format looks like, so compensation is partial.

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 and resource: it verifies size, actual MIME and SHA-256, then imports the reference upload under studio rules. That is far more specific than a bare 'complete upload', and the note that no binary/base64 is passed separates it from the upload-transport step. It never names the sibling it pairs with (kelpo_request_reference_upload), so the differentiation is implied rather than explicit.

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 retry guidance ('Retry the same upload_id safely') tells the agent exactly what to do on failure, and 'No binary or base64 argument' rules out a common wrong invocation. The workflow position — after a ticket exists, this is the finishing call — is clear by implication. There is no explicit when-not or named alternative, which keeps it below a 5.

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