"# Safe Memory with Superagent\n",
"\n",
"This notebook demonstrates how to add **safety middleware** to your Hindsight memory operations using the `hindsight-superagent` package. Every `retain`, `recall`, and `reflect` call automatically passes through [Superagent](https://superagent.sh)'s:\n",
"\n",
"- **Guard** \u2014 blocks prompt-injection attempts before they reach memory or the LLM\n",
"- **Redact** \u2014 strips PII (emails, phone numbers, credit cards, etc.) from content before it's stored\n",
"\n",
"**Key features demonstrated:**\n",
"1. `SafeHindsight` \u2014 drop-in wrapper around the Hindsight client with safety hooks\n",
"2. Automatic PII redaction before storage\n",
"3. Prompt-injection blocking via Guard\n",
"4. Optional read-path redaction (`enable_redact_on_recall`, `enable_redact_on_reflect`)\n",
"5. Batch retain with safety checks\n",
"6. `on_guard` observability callback for logging/analytics\n",
"7. Async context manager for connection lifecycle"

"`hindsight-superagent` gives you a single `SafeHindsight` object that's a drop-in for the regular `Hindsight` client, with Superagent's Guard and Redact wired into every memory operation. The defaults are safe (guard on every op, redact on writes), and every hook can be toggled per-instance or globally via `configure()`.\n",
