colab_update_notebook

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

With no annotations provided, the description carries the full burden. It clearly conveys overwrite semantics by saying 'Replace... entire cell list', which is important behavioral context, but it does not disclose side effects, validation behavior, or what happens if a path is invalid or a cell_type is omitted.

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?

A single sentence with a front-loaded verb and zero filler. It says everything it chooses to say in the most economical form possible.

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?

For a simple two-parameter update with no annotations and no output schema, this is minimally viable: an agent can guess the intent. However, the lack of any guidance about sibling tools and the absence of parameter details make it incomplete for confident autonomous selection.

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%, and the description adds little meaning beyond the schema. 'cell list' vaguely aligns with the cells parameter, but path is not explained, and the cells object structure, source format, and optional cell_type behavior are left entirely to inference.

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?

States a specific verb ('Replace') and resource ('a notebook's entire cell list'). The word 'entire' clearly distinguishes it from incremental cell operations like colab_add_cell or colab_edit_cell.

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 behavior implies whole-list replacement, but the description does not explicitly state when to prefer this over ncremental siblings such as add/edit/delete cell, nor does it mention prerequisites like the notebook needing to exist. No alternatives are named.

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