notebook_edit_metadata

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 'Updates', which implies mutation, but does not disclose whether the update is a full replacement or merge, what permissions are required, whether changes are reversible, or what side effects occur (e.g., clearing existing metadata). For a mutation tool, this is insufficient.

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, concise sentence with no wasted words. It is front-loaded and clear. However, it is so brief that it omits needed behavioral details, but conciseness is about efficiency, not 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 the tool has 2 parameters (including a nested object), no output schema, many sibling tools, and no annotations, the description is insufficient. It does not explain what the metadata object should contain, if it is a full replacement, or what the response looks like. A mutation tool with this complexity requires more 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?

Schema description coverage is 100% (both parameters have descriptions). The description adds 'top-level' to clarify the scope, which is useful but not extensive. The metadata parameter is described as 'New metadata object' in the schema, and the description does not add structural or format details beyond that. Baseline 3 is appropriate as the schema already does the heavy lifting.

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 'Updates the top-level notebook metadata' clearly states the verb (updates) and resource (notebook metadata), distinguishing it from sibling tools like notebook_read_metadata (read) and notebook_edit_cell_metadata (cell-level). It is specific enough to convey the scope, though it could benefit from mentioning what 'top-level' includes (e.g., kernel, language).

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 like notebook_edit_cell_metadata or notebook_read_metadata. There are no exclusions, prerequisites, or context about when updating top-level metadata is appropriate.

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