close_vault

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

Without annotations, description should disclose behavioral traits. It mentions using 'wipeAllAndFree* proxy actions' but does not state that this is a write operation, requires no prior approvals, or that the vault is closed as a result.

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?

Single sentence is concise and front-loaded with the core action. However, it omits parameter details that could be included without verbosity.

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?

Given no output schema and limited description, the tool definition lacks completeness. It does not explain return values, prerequisites, or side effects beyond the basic action.

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 only 25% (only 'network' described). The description adds no explanation for 'cdpId', 'ilk', or 'amountToFree'. Users must infer their meaning from context.

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?

Description clearly states it repays all debt and frees collateral, which matches the name 'close_vault'. It distinguishes from sibling tools like 'repay_usdd' and 'withdraw_collateral' by combining both actions.

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 like 'repay_usdd' or 'withdraw_collateral'. The description does not specify prerequisites or conditions.

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