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

The description usefully discloses that staged parts are deleted from storage, which goes beyond the annotations. However, that stated deletion sits in tension with destructiveHint=false, and no auth requirements, failure modes, or post-abort state are described.

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?

A single tight sentence with the action front-loaded and no filler. It is efficient, though it leaves no room for the usage cues an agent would benefit from.

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?

An output schema exists, so return values need not be explained. For a destructive-ish mutation with an undocumented 'body' parameter and no usage routing, the definition is marginally adequate but incomplete.

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 coverage is only 50%: asset_id is documented but the 'body' object is empty and undocumented. The description mentions no parameters at all, so it fails to compensate for the coverage gap.

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 (aborts) and resource (multi-part upload) plus the side effect (deletes already uploaded parts). An agent can distinguish it from complete_multipart_upload and multipart_upload_list, though no sibling is named explicitly.

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?

There is no when-to-use guidance and no mention of the obvious alternative complete_multipart_upload or of what happens if the upload is already finished. Usage must be inferred entirely from the tool name.

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