get_vault_info

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

Annotations declare readOnlyHint, destructiveHint false, idempotentHint true. Description adds that it returns name, path, file count, size, which is useful behavioral context. However, it doesn't clarify whether it returns all fields or a selected one (via the info parameter), causing slight ambiguity.

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, front-loaded with purpose, no wasted words. Highly concise and efficient.

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?

No output schema, so description should explain return format. It does not specify the shape of the output (e.g., JSON object with fields). Given sibling tools and complexity, the description is slightly incomplete but sufficient for a simple info retrieval.

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 coverage is 100% with an enum parameter. Description adds human-readable labels like 'file count' and 'size', though there is a minor mismatch: description says 'file count' but enum uses 'files', and description omits 'folders'. Still adds meaning beyond raw schema.

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 what the tool does: get vault information (name, path, file count, size). It distinguishes from siblings like get_file_info (specific file) and list_files (file listing), so purpose is specific and clear.

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 explicit guidance on when to use this tool versus alternatives. The description implies it's for vault-level metadata, but does not mention exclusions or when not to use it. Given many sibling tools, more guidance would help.

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