Update Subfolder

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true. The description goes beyond them by disclosing the confirm=true gate, the token/permission requirements, and side-effect potential ("May share access, notify people or incur provider charges"), which is genuinely useful for a 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 purpose sentence is front-loaded and efficient, but the multi-paragraph permission block, fenced code sample and token-scope discussion consume most of the length for a simple two-field update, and the trailing side-effect sentence is generic boilerplate.

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?

With annotations covering the safety profile and the schema fully documenting all eight parameters, the description need only add auth and side-effect context, which it does. The lack of content about return behavior is acceptable since no output schema is needed for an update, though sibling routing remains unaddressed.

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 field including confirm, payload, and payload_file is already documented in the schema. The description only restates the name/description targets and does not add syntax or precedence detail beyond the structured fields, so the baseline 3 applies.

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 opening sentence states a specific verb and resource with the exact mutable fields ("Updates a subfolder's name and/or description"). It is clear and unambiguous, though it does not differentiate itself from nearby siblings like update_folder or create_subfolder.

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 bulk of the description documents authorization prerequisites (required scopes, delegation, expiring tokens) and the confirm=true requirement, which implicitly frames when the call will succeed. However, it offers no guidance on when to prefer this over siblings such as update_folder or when not to use it at all.

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