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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the meaningful fact that runnable_loop_types is a global fixed list while loops is product-specific, but it does not describe what 'status' actually contains (run history, health, last execution) or any pagination or scoping behavior.

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?

It is a single compact sentence with the core payload (provisioned loops and autonomy level) front-loaded, and the trailing clause about runnable_loop_types earns its place by preventing field confusion. The semicolon-chained phrasing is dense but not padded.

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?

For a single-optional-param read tool with no output schema, the description usefully sketches the return shape, which is necessary here. However, it never explains the 'status' aspect implied by the name (run state, autonomy semantics), leaving an agent unsure what to expect beyond a list of loop types and autonomy levels.

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 single optional loop_type parameter is already documented in the schema, and the description does not mention it or explain what happens when it is omitted or set. Baseline 3 applies when the schema carries the parameter burden.

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 names the specific resource (provisioned automated growth marketing loops) and enumerates its contents (autonomy level) plus a second distinct field, runnable_loop_types. It implicitly distinguishes the two return components, though the action verb is only implied by the title and there is no explicit contrast with sibling get_* tools.

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, when-not-to-use, or alternative-tool guidance across the many get_* siblings (get_snapshot, get_enrollment, get_visibility, etc.). The only disambiguation offered is about interpreting the response fields, not about selecting this tool.

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