notebooklm_upload

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 only says 'upload' without disclosing side effects, required authentication, or behavior of parameters like dry_run and create_if_missing. The term 'saved session' hints at a prerequisite but is not explained.

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, which is concise, but it is underspecified given the tool's complexity (4 parameters, no param docs). Conciseness should not sacrifice essential information; here it is too terse.

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 presence of 4 parameters, no annotations, and an output schema (content unknown), the description fails to provide necessary context such as what a 'cluster bundle' is, what a 'saved session' entails, or how to obtain the required inputs. The tool appears to be a mutation with side effects but lacks sufficient detail.

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 input schema has 0% description coverage, and the description adds no information about any of the four parameters. The agent is left to infer meaning from names alone (cluster_slug, dry_run, headless, create_if_missing), which is insufficient for correct invocation.

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 it uploads the latest cluster bundle to NotebookLM using a saved session, specifying the verb (upload) and the resource (cluster bundle to NotebookLM). It is specific enough to convey the action, though it does not differentiate from sibling tools like notebooklm_bundle or notebooklm_generate.

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 is provided on when to use this tool versus alternatives, nor any prerequisites or exclusions. The description simply states what it does without context for appropriate usage.

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