notebook_delete_cell

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

With no annotations, the description fully relies on itself to disclose behavior. It explicitly mentions that a timestamped backup is written before deletion unless checkpoint=false, which is key behavioral detail. However, it does not mention error handling or side effects like file modification.

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 very concise and well-structured: a one-sentence purpose, a key behavioral note about backups, then a clean parameter list. No unnecessary words or redundancy.

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 complexity (3 parameters, no annotations, output schema exists), the description adequately covers the main action, backup behavior, and parameter meanings. It lacks information about return values (though output schema exists) and potential errors, but is fairly complete for a simple deletion tool.

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 description compensates for 0% schema coverage by providing clear, complete explanations for all three parameters: notebook_path (relative path), cell_index (zero-based), and checkpoint (default true with backup behavior). This adds significant value over the raw 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 deletes a cell from a notebook, specifying the action and resource. It distinguishes itself from siblings like notebook_edit_cell or notebook_insert_cell, which have different purposes.

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 implies usage for deletion but does not explicitly differentiate from alternatives (e.g., editing or clearing a cell) or state when not to use the tool. No guidance on prerequisites or context is given.

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