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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Create' implies a write/mutation operation, but the description doesn't disclose any behavioral traits: it doesn't mention permissions required, whether the operation is idempotent, what happens on conflicts (e.g., duplicate names), or what the response contains. For a creation tool with 8 parameters, this leaves critical gaps.

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 extremely concise at just two words plus a bracketed context. There's no wasted verbiage or redundant information. While it's under-specified, it's not wordy or poorly structured.

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 creation tool with 8 parameters, no annotations, and no output schema, the description is severely incomplete. It doesn't explain what a variable group is, when to create one, what the operation returns, or any behavioral considerations. The agent would struggle to use this tool correctly without additional 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 description coverage is 100%, so the schema already documents all 8 parameters with descriptions in Chinese. The English description adds no parameter information beyond what's in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.

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 'Create a variable group' is a tautology that merely restates the tool name. It adds no specificity about what a variable group is, what resource it creates, or how it differs from sibling tools like 'create_global_var' or 'update_variable_group'. The bracketed '[application delivery]' provides minimal context but doesn't clarify the action.

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 guidance on when to use this tool versus alternatives like 'create_global_var' or 'update_variable_group'. The description doesn't mention prerequisites, dependencies, or appropriate contexts for creating a variable group versus other variable-related operations.

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