cloud_subscription_list

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

With no annotations provided, the description carries the full behavioral burden. It clearly signals a read operation via 'Đọc' and 'List', and it discloses the output scope (current plans, renewal period, auto-renew). However, it does not mention whether the list is scoped to the authenticated user, whether only active subscriptions are returned, or what the response format looks like.

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?

Very short and front-loaded, with the Vietnamese phrase carrying more detail than the generic English 'List subscriptions.' There is minor redundancy between the tool name and the English summary, but nothing else is wasted.

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 simple 0-parameter list tool with no output schema, the description covers the resource and the key returned aspects. Still, it leaves gaps around user scoping, whether only active subscriptions are listed, and the exact format of renewal-period and auto-renew fields.

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 tool has zero parameters and the schema coverage is 100%, so there are no parameter semantics for the description to clarify. The 0-parameter baseline of 4 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?

States a clear verb and resource ('List subscriptions') and the Vietnamese description adds the specific data exposed: current plans, renewal period, and auto-renew status. It does not explicitly distinguish itself from vibecloud_subscription_list or the plan/list siblings, but the purpose is unambiguous.

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 such as cloud_plan_list, cloud_packages, or vibecloud_subscription_list. The only implicit cue is the verb 'List' versus update-oriented siblings, but no conditions or exclusions are provided.

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