create_backups_upload

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

Annotations already provide idempotentHint, destructiveHint, and readOnlyHint. The description adds no behavioral context beyond 'act on backups upload', which is vague. It does not mention side effects, authentication, or what happens on success/failure. Given the annotations, the description adds minimal value.

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 short but contains redundant/vague phrasing ('Create or act on') and repeats the endpoint. It could be more concise and front-loaded with the core action. It is not overly long, but lacks precision.

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 tool has a complex body parameter and an output schema, but the description does not clearly explain what the tool does. It points to schema for fields but leaves the operation itself ambiguous. It also does not relate to backup lifecycle or mention any prerequisites. Incomplete for an agent to confidently invoke.

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?

The description clarifies that 'body' is a request payload and directs the agent to read the schema for field details. This is helpful given the schema has no field documentation (0% coverage). However, it does not describe any actual fields or provide syntax, so it only partially compensates.

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 the resource (backups upload) but uses the vague phrase 'Create or act on' which does not specify the exact action. It does not distinguish from sibling tools like create_backups, and the endpoint is merely restated. The verb is present but ambiguous.

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?

No guidance on when to use this tool versus alternatives. The only hint is to read the schema, which is about parameter usage, not tool selection. There is no mention of conditions, prerequisites, or exclusions.

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