upload_iso

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

Annotations already cover read-only/destructive hints; the description adds only the URL source and client availability. It does not disclose potential side effects, whether the upload is asynchronous, whether the confirm flag is a safety guard, or any rate limits. For a mutating operation, this is thin.

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 efficient sentence that front-loads the verb and includes the endpoint path and availability. No filler, but it is arguably too terse to be a 5.

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?

With no output schema and a mutating operation, the description is too sparse: it does not mention the confirm requirement, the relationship to add_iso_image, post-upload behavior, or how the operation integrates with the ISO lifecycle. An agent cannot fully judge invocation context.

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 descriptions cover 100% of parameters (url, name, confirm), so the baseline is 3. The description merely reasserts that the upload is via URL and adds nothing about the name or the confirm semantics; the schema already carries the semantic load.

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 action ('upload') and a specific resource ('new ISO image') with the upload method ('by URL') and the endpoint alias (iso/upload). However, it does not explicitly distinguish this from the sibling add_iso_image, so it is clear but not differentiated.

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 only usage context is 'available to clients,' which is an access statement rather than a use-case selector. There is no when-to-use, no exclusion, and no reference to sibling ISO tools like add_iso_image, mount_iso, or list_iso_images. An agent has no guidance on choosing this over alternatives.

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