gdrive_set_scope

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

No annotations are provided, so the description carries the full burden. It does disclose that this mutates the 'active' root and that it matters in a multi-account setup, but it omits whether the change is persistent, whether the account selection is interactive, and any auth/permission requirements.

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?

A single sentence with the action front-loaded and the qualifying condition appended. No wasted words.

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 zero-parameter state-setting tool with no output schema, the description is minimally adequate: it says what is set and when it applies. It does not explain how the root is chosen among synced accounts or what the resulting effect on gdrive_list_files / gdrive_read_file will be.

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 tool takes zero parameters, so parameter semantics baseline is 4. The description correctly implies the selection is made out-of-band (via synced accounts) rather than through arguments, matching the empty 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?

States a specific verb+resource: 'Sets the active Google Drive root directory.' An agent knows this changes state rather than reading it. It does not distinguish itself from the sibling gdrive_root or onedrive_set_scope, which is the only gap.

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 parenthetical '(when multiple accounts are synced)' implies the condition under which this tool is relevant, but there is no explicit when-to-use/when-not guidance and no pointer to alternatives (e.g. gdrive_root) for inspecting the current scope.

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