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

No annotations exist, so the description carries the full burden: it discloses the return shape (appId, displayName, siteUrl), which is the key behavioral fact for a list tool. It says nothing about ordering, pagination, result limits, or whether all workspace apps are returned, which is a meaningful gap for a collection endpoint.

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?

One sentence, front-loaded with the action and resource, with the returned fields appended as useful detail. Nothing wasted and nothing buried.

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, naming the returned fields is the right compensating move, and for a simple list tool that covers most of what an agent needs. Ordering and pagination behavior remain undisclosed.

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 100%, so the sole parameter (notification_message) is fully documented in the schema. The description adds no parameter context, and notably never connects the fallback-message parameter to the listing behavior — 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?

Specific verb (List) plus resource (SaaS apps/sites) scoped to the Nova workspace, and it names the three fields returned. It doesn't explicitly contrast with create_studio_app, but the read-only verb makes the distinction clear enough.

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 explicit when-to-use statement or named alternative. The intent is implied by 'List ... in your Nova workspace', which is sufficient for such a simple enumeration tool but leaves prerequisites and follow-up routing unstated.

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