notebooklm_download

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

No annotations provided, so description must compensate, but it lacks details on behavior: what happens if no artifact exists, permissions needed, whether it overwrites or creates new files? Does not explain parameters like 'headless' or 'artifact_type'.

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 a single sentence of 8 words, which is concise but lacks necessary detail. It front-loads the main action but sacrifices completeness.

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 3 parameters with no schema descriptions, no annotations, and an output schema (unseen), the description is severely incomplete. It does not explain usage context, output, or prerequisites, leaving the agent underinformed.

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 0%, so description should explain parameters. However, only 'briefing artifact' is mentioned; 'cluster_slug', 'artifact_type', and 'headless' are not described, adding no meaning beyond their names.

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 clearly states the verb 'download' and resource 'latest NotebookLM briefing artifact' with destination 'into the vault'. It distinguishes from siblings like notebooklm_generate (generates) and notebooklm_upload (uploads).

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?

No guidance on when to use this tool versus alternatives (e.g., notebooklm_generate, notebooklm_upload, notebooklm_bundle). No information on prerequisites or conditions like artifact existence.

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