Prompt Redaction Workflow for Coding Agent Logs

Best-fit situations

• A transcript includes API keys, bearer tokens, session cookies, or webhook secrets.
• A contractor needs a client appendix but the raw session mentions private domains and customer names.
• A prompt pack should preserve reusable instructions while removing project-specific data.
• A security reviewer wants evidence that redaction happened before internal sharing.

Operating steps

1. Run automated detection for tokens, private domains, credentials, email addresses, and customer identifiers.
2. Preview each redaction and choose whether to mask, keep, or replace with a stable placeholder.
3. Apply redaction before search indexing or team review when the data source is sensitive.
4. Store redaction decisions beside the prompt session for later audit.
5. Export a client-safe appendix or reusable prompt template with placeholders.

Common risks

• Plain find-and-replace can miss token formats, encoded data, and internal hostnames.
• Over-redaction can remove the context needed to reuse a prompt effectively.
• Under-redaction can disclose confidential systems during client delivery.
• A redaction process without logs is hard to defend later.
