vault_action

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

No annotations are provided, and the description does not disclose behavioral traits such as side effects (e.g., deletion, rotation), required permissions, rate limits, or the security implications of handling master passwords. This is a significant deficiency.

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 concise but too terse for the complexity of the tool. It lists items without structure or hierarchy, which could be improved by grouping actions or providing brief definitions.

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 the tool's multi-action nature, lack of output schema, and zero parameter documentation, the description is grossly incomplete. It omits return values, error conditions, prerequisites, and usage examples for each 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?

With 0% schema description coverage and parameters like 'action', 'master_password', 'key', 'value', and 'encrypt', the description adds no meaning beyond listing allowed action values. The AI cannot infer how to use these parameters across different actions.

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 states 'Perform a vault action' and lists six specific sub-actions (vault_init, vault_store, etc.), making the general purpose clear. However, it does not explain what each sub-action does, which is a minor gap.

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, nor does it specify prerequisites or conditions. For a multi-action tool, this oversight limits the AI's ability to choose appropriately.

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