Does this update my application's dependencies?

No, this skill is specifically designed to update the Claude Code Harness framework files and configurations. it does not affect your project's npm, pip, or other package manager dependencies.

How does the skill handle files I have already customized?

The skill uses a localization judgment system. If a file is detected as 'localized' (modified by the user), it will attempt to merge changes or prompt for confirmation rather than overwriting.

What should I do if the update fails?

The skill automatically creates a timestamped backup in .claude-code-harness/backups/ before any changes are made, allowing you to restore your previous state easily.

Will my custom project settings be overwritten?

No. The update process is non-destructive and specifically preserves custom settings in settings.json, incomplete tasks in Plans.md, and core memory data.
