pii-redactor

What problem does it solve?

Prevents personally identifiable information from being written into logs, prompts, or outbound messages by detecting and redacting it in-flight.

Core Features & Use Cases

• Two-pass PII detection: runs a fast regex pass for high-recall matches and then a Claude-based classification pass to catch what regex misses.
• In-place structured redaction: preserves the original payload structure while replacing detected values with category-specific placeholders (e.g., EMAIL, SSN, CARD).
• Precision-gated safety contract: returns a precision_score and can refuse to release the output when precision falls below the required threshold.
• Safety bindings for privacy: blocks logging of raw unredacted payloads and avoids sending original text through the classifier audit path.

Use case examples: redact PII from an email body during email intake with strictness=high before composing any downstream intent; redact PII from Telegram draft payloads before posting to review and again before final sending.

Quick Start

Use the pii-redactor skill to redact all PII from an email intake payload with strictness set to high.
