Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It implies a read-only operation via 'List' and mentions the returned 'workflow status', which is useful context. However, it does not disclose pagination, ordering, scope (all projects vs. scoped), or whether any side effects exist. For a simple no-parameter list, this is minimally adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
