configure_vault

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

Annotations already indicate readOnlyHint=false. The description adds the key behavioral insight that this is a first-step configuration action. It does not elaborate on side effects or prerequisites, but the essential 'call first' behavior is disclosed.

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?

Two concise sentences. The first states the action, the second adds a usage guideline. No wasted words, front-loaded.

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 simple input (one string param) and presence of both annotations and an output schema, the description covers what the tool does and when to use it. It lacks details about permissions or consequences, but it's still fairly complete for its simplicity.

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 0%, and the description only mentions 'vault path' without explaining format, constraints, or example. The single parameter is simple, but the description does not compensate for the lack of schema descriptions.

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 verb 'configure' with resource 'vault path' is specific. The description also provides context that this tool should be called first if the server started without a --vault argument. Sibling tools (e.g., check_vault_health, repair_vault) have distinct purposes, so no confusion.

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?

Explicit guidance: 'Call this first if the server started without a --vault argument.' This clearly indicates when to use it and implies that if the server started with --vault, this may not be needed. No alternatives are mentioned, but siblings cover unrelated tasks.

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