run_cell_range

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

With no annotations, the description must disclose behavior. It only states the basic action; it does not mention side effects (e.g., whether it clears outputs), how stopOnError affects execution, or any other behavioral traits. This is insufficient for a code execution tool.

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 sentence, which is concise but lacks structure and important details. It could be expanded to cover key aspects without being verbose.

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 5 parameters with no descriptions, many sibling run tools, and no output schema, the description is far from complete. It fails to explain return values, error handling, execution behavior, or when to use this tool. Agents would struggle to invoke it correctly.

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%, so the description must explain parameters. It only implies 'cellIndexStart' and 'cellIndexEnd' with 'inclusive index range', but adds no meaning for 'stopOnError', 'includeOutputs', or 'timeoutSeconds'. This is a significant 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 'Runs code cells in an inclusive index range' clearly states the action (run) and the resource (code cells in a range). It distinguishes from siblings like 'run_code_cell' (single cell) and 'run_all_cells' (all cells).

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 on when to use this tool vs alternatives like 'run_code_cell', 'run_code_cells', or 'run_all_cells'. With many sibling tools, the lack of usage context makes selection difficult.

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