It masks secrets before tools run and censors sensitive fields in transcripts.
Data leakage for enterprises using Ai coding is a ███ . Redaction hooks solve ██ problems by catching secrets before they leak. Here’s how I do it.
A redaction hook sits between your agent and the outside world. Every time Claude Code reads a file, runs a shell command, or fetches a web resource, the hook scans for sensitive patterns like API keys, tokens, or passwords. If it sees something dangerous, it either masks it with a placeholder or blocks the request outright. That way, your logs and transcripts remain useful but never expose private values.
