+# /purge-file-from-git
+
+**Description:** Completely remove a file from git history using git-filter-repo. This is a destructive operation that rewrites history and requires force-pushing.
+
+**Parameters:**
+- file_path: The relative path to the file to purge from git history (e.g., "secrets.env", "large-file.bin", "./config/passwords.txt")
+
+**Example usage:**
+- `/purge-file-from-git secrets.env`
+- `/purge-file-from-git config/api-keys.json`
+- `/purge-file-from-git data/large-dataset.csv`
+

+## Prompt
+
+I'll purge `{{file_path}}` from the entire git history. This is a **destructive operation** that will:
+
+1. **Rewrite all commits** in the repository's history
+2. **Change commit hashes** for affected commits and their descendants
+3. **Require a force-push** if already pushed to remote
+4. **Potentially cause issues** for collaborators who have cloned the repo
+
+**Before proceeding, I need to confirm:**
+
+1. **Is this branch shared with others?** If so, they'll need to re-clone or carefully rebase after this operation.
+2. **Have you pushed this branch to a remote?** If yes, you'll need to force-push afterward.
+3. **Do you want to proceed with rewriting the git history?**
+
+Once confirmed, I will:
+
+### Process:
+
+1. **Verify prerequisites**:
+   - Check if `git-filter-repo` is installed (install if needed)
+   - Check current git status
+
+2. **Execute purge**:
+   - Clean any previous filter-repo state
+   - Use `git filter-repo --path {{file_path}} --invert-paths --force`
+   - Restore the origin remote (filter-repo removes it as a safety measure)
+
+3. **Ask about .gitignore**:
+   - Prompt: "Would you like to add `{{file_path}}` to .gitignore to prevent future accidental commits?"
+   - If yes: Add the file to .gitignore and commit the change
+   - If no: Skip this step
+
+4. **Provide next steps**:
+   - Explain how to force-push: `git push --force origin <branch>`
+   - Warn about impact on collaborators
+   - Provide recovery instructions for team members
+
+Let me know if you want to proceed with purging `{{file_path}}` from git history.
