Headless extraction with Claude Code

Pipe your text through `extract_pattern` to get clean data without leaving your terminal. It’s built for CI/CD pipelines and shell scripts. It outputs raw data you can feed into other CLI utilities. Claude Code handles the logic while the server keeps the regex execution fast.

Redact data in Claude Code pipelines

Clean your production logs automatically. Use `mask_sensitive_data` to strip PII before your scripts store or display the text. It replaces sensitive patterns with [REDACTED]. Integrate this into your build process to keep PII out of your deployment artifacts.

Validate patterns in Claude Code

Ensure your configuration files are valid at runtime. Use `validate_pattern` to check formats before Claude Code continues its execution. It returns a simple exit status. Use this to trigger alerts or stop pipelines if the data doesn't match the expected format.
