   2. Semantic intent verification before tool execution
   3. Dynamic risk scoring across agent trajectories (catches crescendo attacks)
 - These move us from "prompt injection scanner" to "agent runtime security platform"
+
+## 2026-05-28: OpenClaw agent hardening wired into SDK
+- **Boundaries:** `auto_wrap_untrusted` on `RETRIEVED` / `TOOL_OUTPUT` in `InputPipeline`; public `Guard.wrap_for_context()`
+- **Session policy:** existing CaMeL-lite taint + tool profiles unchanged; now complemented by trajectory + intent gates
+- **Crescendo:** `TrajectoryConfig` — escalating `risk_trajectory` slope → REVIEW/BLOCK findings on all pipelines
+- **Intent:** `IntentConfig` — informational user intent + side-effect tool → REVIEW
+- **Hermes/persona:** named persona + red-team regex patterns in injection scanner
+- **Out of SDK scope:** container sandbox, channel pairing, filesystem/network egress (host responsibility)
+- **Detail:** `.context/research/openclaw-agent-security.md`
+
+- **Question:** Use Microsoft Presidio to filter agent-exposed PII?
+- **Answer:** Useful as optional server-side benchmark / interim `PrivacyFilterService` backend only — not a replacement for Unplug or the planned unplug-safeguard PF head.
+- **Already covered:** `LeakageScanner` regex (email, phone, SSN, keys) + output pipeline span redaction + `ScanPolicy` coverage BLOCK.
+- **Presidio adds:** names, addresses, international/custom entities — where regex under-recalls.
+- **Does not add:** injection, destructive tools, taint, fail-closed guard architecture.
+- **Production path unchanged:** unplug-safeguard Privacy Filter on server (see span-pipeline spec Stage 3).
+- **Detail:** `.context/research/presidio-pii.md`

+# Publish unplug-ai to PyPI
+
+Package: **`unplug-ai`** · Import: **`from unplug import Guard`**
+
+## One-time setup
+
+1. Create a [PyPI account](https://pypi.org/account/register/) (org account recommended).
+2. Create an API token with **Upload** scope for project `unplug-ai` (or entire account for first release).
+3. In [UnplugAI/Unplug](https://github.com/UnplugAI/Unplug) → **Settings → Secrets → Actions**, add:
+
+   | Secret           | Value        |
+   |------------------|--------------|
+   | `PYPI_API_TOKEN` | `pypi-...`   |
+
+## Publish
+
+**CI (recommended):** Actions → **Publish to PyPI** → Run workflow  
+Or tag a GitHub Release — workflow runs on `release: published`.
+
+**Local:**
+
+```bash
+cd sdk
+uv sync --dev
+uv run pytest -q
+uv build
+UV_PUBLISH_TOKEN=pypi-... uv publish
+```
+
+## After publish
+
+- Site links: `pip install unplug-ai` → https://pypi.org/project/unplug-ai/
+- Bump `sdkVersion` in `unplug-site/public/js/core/site-config.jsx` when releasing new versions.

 # Unplug SDK
 
 Pull the plug on bad AI. Runtime enforcement layer for AI agents.
+
+```bash
+pip install unplug-ai
+```
+
+```python
+from unplug import Guard
+
+guard = Guard()  # local mode, offline
+result = guard.scan("Ignore all previous instructions", source="user")
+
+if not result.safe:
+    text = result.redacted_text
+```
+
+## Agent host checklist (OpenClaw-style)
+
+Use this flow when wiring Unplug into an agent that fetches external content or calls tools:
+
+1. **Scan user input** — `guard.scan(text, source="user")` (captures `user_intent` for later gates).
+2. **Wrap untrusted content** before inserting into LLM context — `guard.wrap_for_context(rag_chunk, source="retrieved")`. Auto-wrap also runs on `scan(..., source="retrieved")` when `[boundaries] auto_wrap_untrusted = true`.
+3. **After fetch/read tools** — `guard.notify_taint_source("web_fetch")` so side-effect tools require review.
+4. **Before every tool call** — `guard.check_tool_call(name, args, taint_sources=[...])`. Destructive calls block; tainted session + side-effect → `REVIEW`.
+5. **Scan agent output** — `guard.scan_output(text)`. Set `strip_on_output = true` to remove boundary markers from redacted output.
+6. **New trusted turn** — `guard.reset_session_taint()` when the user starts a fresh instruction with no untrusted context.
+
+Optional: run `unplug-audit --probes` after swapping in a new ML checkpoint.
