colab_execute_notebook

Execute notebook cells in a Colab runtime, writing results to an output .ipynb file. Keeps a checkpoint on failure for reliable reruns.

Instructions

Execute notebook cells. On failure keep the input/output checkpoint; reacquire and rerun deliberately.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
outputYesLocal output .ipynb path to create or replace.
sourceYesExisting local .ipynb input path.
sessionNoTracked session name. Null is allowed only when exactly one session exists.
cell_timeoutNoMaximum seconds per code cell.
Behavior2/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions a failure-handling behavior (keep checkpoint, rerun) but does not disclose other impacts such as file overwriting, session management, or resource/rate limitations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences convey the core action and a failure-handling trait. However, the second sentence uses cryptic phrasing ('reacquire and rerun deliberately') that might confuse, though it remains concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is minimal for a tool with 4 parameters and no output schema. It does not explain the return value, the relationship between source and output paths, or session semantics beyond what the schema already provides. Missing context that an agent needs to use it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema descriptions cover 100% of parameters. The tool description adds no additional semantic detail about the parameters, so it meets the baseline expected for high schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the action (execute) and the resource (notebook cells), and the tool name 'notebook' distinguishes it from generic 'colab_execute' or 'colab_run_command'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for executing notebook cells but provides no explicit guidance on when to prefer this over sibling tools like colab_execute, nor does it state exclusions or prerequisites such as session requirements.

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