create_secret_folder

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

With no annotations, the description must carry the behavioral burden. It usefully discloses that external writes are required and that existing folders should be checked first, but it omits permissions, duplicate-name handling, idempotency, and return behavior for this mutation.

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 short sentences, front-loaded with the core action and followed by the key prerequisite and side effect. There is no redundant or wasted text.

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 create tool with no annotations or output schema, the description is minimally adequate but incomplete. It communicates creation, pre-check, and external writes, yet leaves out duplicate behavior, permissions, and what the call returns.

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?

The only parameter, 'name', has 0% schema description coverage, so the description must compensate. It only implies that 'name' is a vault folder name and adds no format, constraint, or uniqueness guidance.

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 has a specific verb ('Create') and resource ('vault folder'), and it distinguishes the tool from create_secret by focusing on folders. It does not explicitly name the sibling list_secret_folders as the pre-check tool, so it falls short of full sibling differentiation.

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 phrase 'after checking existing folders' gives a clear usage prerequisite, and 'Requires external writes' signals an important operating condition. There is no explicit when-not guidance or named alternative tool, but the context for when to use it is clear.

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