anonymise
Anonymise CSV files by removing personal identifying information and adding datetime stamps. Use when user wants to process a new CSV file or strip PII from data.
Best use case
anonymise is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Anonymise CSV files by removing personal identifying information and adding datetime stamps. Use when user wants to process a new CSV file or strip PII from data.
Teams using anonymise should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# CSV Anonymiser When the user wants to anonymise a CSV file or process new data: ## 1. Check .gitignore First, verify that CSV files are excluded from git: ```bash cat .gitignore ``` If `*.csv` is not present, add it: ```bash echo "*.csv" >> .gitignore ``` ## 2. Identify the CSV File The script can auto-detect new CSV files: - **Auto-detection**: Files without a timestamp pattern (YYYYMMDD_HHMMSS) in their name - **New files**: Any CSV file that hasn't been processed yet - If multiple new files exist, the script will list them and ask user to specify which one ## 3. Remove Personal Identifying Information Columns to remove are configured in `~/.agents/skills/anonymise/config.txt`: - One column header per line - Lines starting with `#` are comments - Default includes `"Record - Airtable ID"` (PII) Process the file: 1. Read the CSV file 2. Remove all columns listed in `~/.agents/skills/anonymise/config.txt` 3. Keep all other columns intact 4. Preserve the header row (minus the removed columns) ## 4. Add Datetime Stamp The script will: 1. Create a new file with format: `YYYYMMDD_HHMMSS.csv` (just the timestamp) 2. Delete the original file Example: `ILR data 25_26-Social value data for Dingley.csv` becomes `20231216_143022.csv` ## 5. Run the Anonymisation Script Execute the Python script located in the same directory as this skill: **Auto-detect mode** (finds CSV files without timestamps): ```bash python3 ~/.agents/skills/anonymise/anonymise.py ``` **Specific file mode**: ```bash python3 ~/.agents/skills/anonymise/anonymise.py "filename.csv" ``` If multiple new files are found in auto-detect mode, the script will list them and you'll need to specify which one to process. ## 6. Confirm Completion After processing: 1. Confirm the anonymised file was created with timestamp 2. Confirm the original file was removed 3. Confirm .gitignore includes `*.csv` 4. Remind user that CSV files won't be committed to git ## Notes - Uses British English spelling throughout - Handles UTF-8 BOM encoding (`utf-8-sig`) for compatibility - Preserves all data except the first column - Assumes consistent CSV structure across files - Files are automatically excluded from version control
