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

With no annotations provided, the description carries full burden for behavioral disclosure but offers none. It doesn't indicate whether this is a destructive operation, what permissions are required, whether it's reversible, what happens to associated resources, or what the expected outcome is (e.g., order status change). The description is purely functional without behavioral context.

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—just two words plus a bracketed prefix—with no wasted verbiage. However, the prefix '[VM Deploy Order Management]' adds minimal value and could be integrated more smoothly. The structure is front-loaded but under-specified, leaning toward brevity over clarity.

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 mutation tool ('stop') with no annotations and no output schema, the description is incomplete. It doesn't explain what 'stopping' entails behaviorally, what the result looks like, or error conditions. Given the complexity implied by three required IDs and the lack of structured safety hints, the description fails to provide adequate context for safe and effective use.

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%, with all three parameters clearly documented in Chinese ('企业Id', '流水线Id', '部署单Id'). The description adds no additional parameter semantics beyond what the schema provides, such as format examples or inter-parameter relationships. Given the high schema coverage, a baseline score of 3 is appropriate.

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 'Stop VM deploy order' is essentially a tautology that restates the tool name with minimal elaboration. It specifies the verb 'stop' and resource 'VM deploy order' but lacks specificity about what stopping entails (e.g., halting execution, canceling pending tasks) and doesn't distinguish it from sibling tools like 'cancel_change_request' or 'resume_vm_deploy_order' beyond the resource name.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., the deploy order must be running), exclusions (e.g., cannot stop completed orders), or comparisons to similar tools like 'cancel_change_request' or 'resume_vm_deploy_order', leaving the agent with no context for decision-making.

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