Skill v1.0.0

version: "1.0.0" name: changing-notebooks description: | Invoke this skill when making any modification to a notebook (.ipynb) in the OCI agent. Keywords:

• .ipynb, Jupyter notebook
• cell injection, comment-out cell
• "# === INJECTED BY OCI AGENT === #"
• "# === COMMENTED OUT BY OCI AGENT === #"
• econml.ipynb, notebooks/ directory
• parameterizing notebooks

• Never delete cells. Comment out their contents and add the header # === COMMENTED OUT BY OCI AGENT === #
• Mark injected cells with the header # === INJECTED BY OCI AGENT === #
• Never modify cell contents. Inject a new cell that implements the modification and comment out the old one.
• Always leave the audit trail. No exceptions. Apply comment-out + inject for every notebook edit — including one-line fixes, edits the user requested directly, and edits in areas the user has previously collapsed to clean cells. The audit trail is the contract; pruning it is the user's call, not the agent's. The only exception: when in the same session you are rewriting your own prior injected cell — that case has no user-authored work to preserve.

Cell placement

• Place each injected cell immediately after the cell it replaces. Keep the commented-out cell and its replacement adjacent so the diff is local.
• Preserve cell type: replace a code cell with a code cell, a markdown cell with a markdown cell.
• Do not inject above the top-of-notebook configuration cell. Do not inject below the results serialization cell at the bottom — nb_runner.py appends that at execution time.

Scope

• In-scope modifications: estimator config, diagnostic / plotting cells, intermediate computation cells, code-cell logic changes.
• Out-of-scope: editing the configuration cell to change spec parameters — change the spec instead, nb_runner.py injects parameters at run time.
• Out-of-scope: adding a results serialization cell — nb_runner.py owns that and will append it.
