configure_mode

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

No annotations are provided, so the description carries full burden. It discloses authentication requirements, potential 400/401 errors, and the return dictionary structure. However, it doesn't mention whether switching modes affects current session state beyond auth.

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 description is well-structured with an IMPORTANT section, bullet points, and clear Args/Returns. It is concise yet comprehensive, with 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?

Given the complexity of authentication modes and three parameters, the description covers auth, parameters, and return value. It lacks details on error handling beyond auth errors, but overall completes the picture.

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?

With 0% schema description coverage, the description adds meaning for all three parameters: mode (personal/enterprise), project_id (required for enterprise, source), location (default global). It clarifies constraints not in 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?

The description explicitly states it configures NotebookLM mode (personal or enterprise), which is a specific verb-resource pair. It distinguishes from siblings like refresh_auth or save_auth_tokens by focusing on mode switching.

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 description provides explicit authentication prerequisites and warns about errors when switching modes. It doesn't list alternative tools for similar tasks but gives clear context for when to use this tool.

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