Create Subfolder

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered. The description adds real context the annotations do not: the exact permission scopes needed, the delegation/expiring-token authorization model, the position-assignment behavior, and that confirm=true is required for the 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?

The position behavior is front-loaded correctly, but the long permission section with a duplicated block of OAuth scope prose is dense and repetitive. The final sentence about sharing, notifications and charges is useful but tacked on after the permission detail rather than integrated.

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 mutation tool with no output schema and a nested payload object, the definition covers the key gaps: required permission, confirm requirement, and position behavior. It would be stronger if it clarified how payload and payload_file interact with the body flags, but otherwise the agent has what it needs to call it correctly.

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%, so every parameter including confirm, payload and payload_file is already documented. The description adds only the confirm=true requirement, which is also in the schema, so it does not materially extend parameter meaning beyond the structured fields.

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 definition opens with a specific verb and resource: 'Creates a new subfolder within a folder,' and adds the scoping behavior that the subfolder receives 'the next available position.' An agent can tell this apart from create_folder, update_subfolder and delete_subfolder without opening the schemas.

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?

There is no explicit when-to-use or when-not-to-use guidance. The description never says to prefer create_folder for top-level folders or which sibling to use for moving an existing subfolder, so the agent must infer the difference from names alone.

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