Agent skill that patches the Claude Code (`anthropic.claude-code`) extension so it stops locking editor groups and creating a stray empty column (blank pane with only an X) when opened next to Cursor Agents.

This skill fixes two existing issues by patching the obfuscated minified `extension.js` on the local machine (there is no setting for either behavior):

anthropics/claude-code#80148 — extension programmatically locks the editor group (workbench.action.lockEditorGroup), bypassing workbench.editor.autoLockGroups
anthropics/claude-code#83333 — findUnusedColumn() creates an empty editor group (blank pane with only an X) when opening beside Cursor Agents

Extension updates install into a fresh directory, so re-run the patch after every update.

Install

npx skills add ChubbyDuck/patch-claude-code-lock

For a global Cursor install:

npx skills add ChubbyDuck/patch-claude-code-lock -g -a cursor -y

Browse the skill on [skills.sh](https://skills.sh/ChubbyDuck/patch-claude-code-lock).

Usage

Ask your agent to apply the Claude Code lock patch, or run it yourself from this skill directory:

python3 scripts/patch.py

The script finds every `anthropic.claude-code-*` install under `~/.cursor/extensions` and `~/.vscode/extensions`. After a successful patch, reload the window (`Developer: Reload Window`), close any leftover empty group once, and unlock any already-locked group once.
