unset_default_vault

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

No annotations are provided, so the description carries the full burden for disclosing behavioral traits. It only says 'Unset default vault setting' and does not mention side effects, reversibility, permissions, or whether the action is idempotent. The confirm parameter hints at a write operation, but that information lives in the schema, not the description.

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 a single short sentence with no filler, and the action is front-loaded. It is structurally clean, though slightly too terse to fully earn a top score.

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 one-parameter write operation, the description is minimally viable. However, it omits useful context such as that this only clears the default-vault preference and does not delete the vault, and it does not connect to the paired set_default_vault tool.

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%, and the confirm parameter is already described as 'Must be true to execute the write operation.' The tool description adds no additional parameter meaning, so the baseline of 3 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?

The description uses a specific verb ('Unset') and a clear resource ('default vault setting'), so an agent can understand the core action. It is implicitly differentiated from the sibling set_default_vault by the opposite direction of the operation, though it does not explicitly state that distinction.

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 gives no guidance on when to use this tool versus set_default_vault or view_settings. The intended usage context must be inferred from the tool name and sibling list, which is not sufficient for reliable tool selection.

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