notebook_add_local_file

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

With no annotations and minimal description, the tool fails to disclose critical behavioral traits such as whether the file is uploaded or referenced, size limits, error handling, or asynchronous behavior. The description only states the basic action.

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 efficient sentence, front-loading the key action and resource. However, it may be overly terse for a tool with no annotations or output schema.

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 tool has two required parameters, no output schema, and no annotations, the description is insufficient. It lacks details on file handling, validation, or return behavior, making it incomplete for effective agent use.

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 coverage is 50% (only path has a description). The description adds context for the path parameter by specifying absolute path and allowed extensions, but fails to explain notebook_id. This partially compensates for the coverage gap.

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 'Add', the resource 'local file', and the supported file types 'PDF or text/markdown'. It effectively distinguishes this tool from siblings like notebook_add_drive or notebook_add_url by specifying 'local file'.

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 no guidance on when to use this tool versus its siblings (e.g., notebook_add_drive, notebook_add_url). There are no prerequisites, exclusions, or alternative suggestions, leaving the agent to infer usage from the name alone.

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