set_notebook_directory

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

Annotations are present (readOnlyHint=false, destructiveHint=false, idempotentHint=false), and the description describes a write operation, consistent with annotations. However, it adds no extra behavioral context, such as whether the directory is created if missing or if validation occurs, which limits transparency.

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 short with three sentences, but some redundancy exists between 'All subsequent notebook operations will use this directory' and 'Useful for specifying where notebooks should be saved and loaded from'. It could be more compact.

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's simplicity (single parameter, no output schema), the description covers the basic purpose and effect. However, it omits details like whether the directory must already exist, if it's session-scoped, or if it affects existing operations, leaving minor gaps.

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 schema has one required parameter 'path' with 0% description coverage. The description does not elaborate on its format, examples, or allowed values, providing no added meaning beyond the 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 clearly states the tool sets the working directory for notebook operations, effectively communicating its function. However, it could better distinguish from `get_notebook_directory` by emphasizing the 'set' aspect, though the verb 'Set' already does so.

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 explains that subsequent notebook operations will use this directory and that it's useful for saving/loading, offering some guidance on when to use. It lacks explicit when-not-to-use or alternatives, but the context is clear.

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