notebook_edit_cell_output

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

No annotations are provided, so the description carries full burden. It merely states the tool allows setting cell outputs but does not disclose behavioral traits like whether outputs are overwritten entirely, required format of the outputs array, or side effects (e.g., updating execution count). 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 short sentence (7 words), which is concise and front-loaded with the verb and resource. However, it sacrifices specificity for brevity; every word earns its place but could be more precise.

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 is a mutation with three required parameters and no output schema or annotations, the description should provide more context for correct use. It does not explain the effect (e.g., replacement, validation), expected output structure, or potential errors, leaving significant gaps for an AI agent.

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%, with each parameter documented clearly (path, outputs, cell_index). The description adds no additional meaning beyond the schema, so a baseline score of 3 is appropriate.

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 uses 'direct manipulation and setting of cell outputs', which clearly indicates the tool modifies notebook cell outputs. It distinguishes from siblings like notebook_read_cell_output (read-only) and notebook_clear_cell_outputs (clear). However, 'direct manipulation' is slightly vague; a more specific verb like 'replace' would improve precision.

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 provides no guidance on when to use this tool versus alternatives such as notebook_edit_cell (for editing source) or notebook_clear_cell_outputs (for clearing). No context about prerequisites, conditions, or use cases is given.

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