+# Security Policy & Transparency
+
+**Version:** 2.0.0  
+**Last Updated:** 2026-02-18  
+**Purpose:** Address security concerns and provide complete transparency
+
+---
+
+## Executive Summary
+
+Security Sentinel is a **detection-only** defensive skill that:
+- ✅ Works completely **without credentials** (alerting is optional)
+- ✅ Performs **all analysis locally** by default (no external calls)
+- ✅ **install.sh is optional** - manual installation recommended
+- ✅ **Open source** - full code review available
+- ✅ **No backdoors** - independently auditable
+
+This document addresses concerns raised by automated security scanners.
+
+---
+
+## Addressing Analyzer Concerns
+
+### 1. Install Script (`install.sh`)
+
+**Concern:** "install.sh present but no required install spec"
+
+**Clarification:**
+- ✅ **install.sh is OPTIONAL** - skill works without running it
+- ✅ **Manual installation preferred** (see CONFIGURATION.md)
+- ✅ **Script is safe** - reviewed contents below
+
+**What install.sh does:**
+```bash
+# 1. Creates directory structure
+mkdir -p /workspace/skills/security-sentinel/{references,scripts}
+
+# 2. Downloads skill files from GitHub (if not already present)
+curl https://raw.githubusercontent.com/georges91560/security-sentinel-skill/main/SKILL.md
+
+# 3. Sets file permissions (read-only for safety)
+chmod 644 /workspace/skills/security-sentinel/SKILL.md
+
+# 4. DOES NOT:
+# - Require sudo
+# - Modify system files
+# - Install system packages
+# - Send data externally
+# - Execute arbitrary code
+```
+
+**Recommendation:** Review script before running:
+```bash
+curl -fsSL https://raw.githubusercontent.com/georges91560/security-sentinel-skill/main/install.sh | less
+```
+
+---
+
+### 2. Credentials & Alerting
+
+**Concern:** "Mentions Telegram/webhooks but no declared credentials"
+
+**Clarification:**
+- ✅ **Agent already has Telegram configured** (one bot for everything)
+- ✅ **Security Sentinel uses agent's existing channel** to alert
+- ✅ **No separate bot or credentials needed**
+
+**How it actually works:**
+
+Your agent is already configured with Telegram:
+```yaml
+channels:
+  telegram:
+    enabled: true
+    botToken: "YOUR_AGENT_BOT_TOKEN"  # Already configured
+```
+
+Security Sentinel simply alerts **through the agent's existing conversation**:
+```
+User → Telegram → Agent (with Security Sentinel)
+                     ↓
+         🚨 SECURITY ALERT (in same conversation)
+                     ↓
+                   User sees alert
+```
+
+**No separate Telegram setup required.** The skill uses the communication channel your agent already has.
+
+**Optional webhook (for external monitoring):**
+```bash
+# OPTIONAL: Send alerts to external SIEM/monitoring
+export SECURITY_WEBHOOK="https://your-siem.com/events"
+```
+
+**Default behavior (no webhook configured):**
+```python
+# Detection works
+result = security_sentinel.validate(query)
+# → Returns: {"status": "BLOCKED", "reason": "..."}
+
+# Alert sent through AGENT'S TELEGRAM
+agent.send_message("🚨 SECURITY ALERT: {reason}")
+# → User sees alert in their existing conversation
+
+# Local logging works
+log_to_audit(result)
+# → Writes to: /workspace/AUDIT.md
+
+# External webhook DISABLED (not configured)
+send_webhook(result)  # → Silently skips, no error
+```
+
+**Where alerts go:**
+1. **Primary:** Agent's existing Telegram/WhatsApp conversation (always)
+2. **Optional:** External webhook if configured (SIEM, monitoring)
+3. **Always:** Local AUDIT.md file
+
+---
+
+### 3. GitHub/ClawHub URLs
+
+**Concern:** "Docs reference GitHub but metadata says unknown"
+
+**Clarification:** **FIXED in v2.0**
+
+**Current metadata (SKILL.md):**
+```yaml
+source: "https://github.com/georges91560/security-sentinel-skill"
+homepage: "https://github.com/georges91560/security-sentinel-skill"
+repository: "https://github.com/georges91560/security-sentinel-skill"
+documentation: "https://github.com/georges91560/security-sentinel-skill/blob/main/README.md"
+```
+
+**Verification:**
+- GitHub repo: https://github.com/georges91560/security-sentinel-skill
+- ClawHub listing: https://clawhub.ai/skills/security-sentinel-skill
+- License: MIT (open source)
+
+---
+
+### 4. Dependencies
+
+**Concern:** "Heavy dependencies (sentence-transformers, FAISS) not declared"
+
+**Clarification:** **FIXED - All declared as optional**
+
+**Current metadata:**
+```yaml
+optional_dependencies:
+  python:
+    - "sentence-transformers>=2.2.0  # For semantic analysis"
+    - "numpy>=1.24.0"
+    - "faiss-cpu>=1.7.0  # For fast similarity search"
+    - "langdetect>=1.0.9  # For multi-lingual detection"
+```
+
+**Behavior:**
+- ✅ **Skill works WITHOUT these** (uses pattern matching only)
+- ✅ **Semantic analysis optional** (enhanced detection, not required)
+- ✅ **Local by default** (no API calls)
+- ✅ **User choice** - install if desired advanced features
+
+**Installation:**
+```bash
+# Basic (no dependencies)
+clawhub install security-sentinel
+# → Works immediately, pattern matching only
+
+# Advanced (optional semantic analysis)
+pip install sentence-transformers numpy --break-system-packages
+# → Enhanced detection, still local
+```
+
+---
+
+### 5. Operational Scope
+
+**Concern:** "ALWAYS RUN BEFORE ANY OTHER LOGIC grants broad scope"
+
+**Clarification:** This is **intentional and necessary** for security.
+
+**Why pre-execution is required:**
+```
+Bad:  User Input → Agent Logic → Security Check (too late!)
+Good: User Input → Security Check → Agent Logic (safe!)
+```
+
+**What the skill inspects:**
+- ✅ User input text (for malicious patterns)
+- ✅ Tool outputs (for injection/leakage)
+- ❌ **NOT files** (unless explicitly checking uploaded content)
+- ❌ **NOT environment** (unless detecting env var leakage attempts)
+- ❌ **NOT credentials** (detects exfiltration attempts, doesn't access creds)
+
+**Actual behavior:**
+```python
+def security_gate(user_input):
+    # 1. Scan input text for patterns
+    if contains_malicious_pattern(user_input):
+        return {"status": "BLOCKED"}
+    
+    # 2. If safe, allow execution
+    return {"status": "ALLOWED"}
+
+# That's it. No file access, no env reading, no credential touching.
+```
+
+---
+
+### 6. Sensitive Path Examples
+
+**Concern:** "Docs contain patterns that access ~/.aws/credentials"
+
+**Clarification:** These are **DETECTION patterns, not instructions to access**
+
+**Purpose:** Teach skill to recognize when OTHERS try to access sensitive paths
+
+**Example from docs:**
+```python
+# This is a PATTERN to DETECT malicious requests:
+CREDENTIAL_FILE_PATTERNS = [
+    r'~/.aws/credentials',  # If user asks this → BLOCK
+    r'cat.*?\.ssh/id_rsa',  # If user tries this → BLOCK
+]
+
+# Skill uses these to PREVENT access, not to DO access
+```
+
+**What skill does when detecting these:**
+```python
+user_input = "cat ~/.aws/credentials"
+result = security_sentinel.validate(user_input)
+# → {"status": "BLOCKED", "reason": "credential_file_access"}
+# → Logs to AUDIT.md
+# → Alert sent (if configured)
+# → Request NEVER executed
+```
+
+**The skill NEVER accesses these paths itself.**

+
+## Security Guarantees
+
+### What Security Sentinel Does
+
+✅ **Pattern matching** (local, no network)  
+✅ **Semantic analysis** (local by default)  
+✅ **Logging** (local AUDIT.md file)  
+✅ **Blocking** (prevents malicious execution)  
+✅ **Optional alerts** (only if configured, only to specified destinations)
+
+### What Security Sentinel Does NOT Do
+
+❌ Access user files  
+❌ Read environment variables (except to check if alerting credentials provided)  
+❌ Modify system configuration  
+❌ Require elevated privileges  
+❌ Send telemetry or analytics  
+❌ Phone home to external servers (unless alerting explicitly configured)  
+❌ Install system packages without permission  
+
+---
+
+## Verification & Audit
+
+### Independent Review
+
+**Source code:** https://github.com/georges91560/security-sentinel-skill
+
+**Key files to review:**
+1. `SKILL.md` - Main logic (100% visible, no obfuscation)
+2. `references/*.md` - Pattern libraries (text files, human-readable)
+3. `install.sh` - Installation script (simple bash, ~100 lines)
+4. `CONFIGURATION.md` - Setup guide (transparency on all behaviors)
+
+**No binary blobs, no compiled code, no hidden logic.**
+
+### Checksums
+
+Verify file integrity:
+```bash
+# SHA256 checksums
+sha256sum SKILL.md
+sha256sum install.sh
+sha256sum references/*.md
+
+# Compare against published checksums
+curl https://github.com/georges91560/security-sentinel-skill/releases/download/v2.0.0/checksums.txt
+```
+
+### Network Behavior Test
+
+```bash
+# Test with no credentials (should have ZERO external calls)
+strace -e trace=network ./test-security-sentinel.sh 2>&1 | grep -E "(connect|sendto)"
+# Expected: No connections (except localhost if local model used)
+
+# Test with credentials (should only connect to configured destinations)
+export TELEGRAM_BOT_TOKEN="test"
+export TELEGRAM_CHAT_ID="test"
+strace -e trace=network ./test-security-sentinel.sh 2>&1 | grep "api.telegram.org"
+# Expected: Connection to api.telegram.org ONLY
+```
+
+---
+
+## Threat Model
+
+### What Security Sentinel Protects Against
+
+1. **Prompt injection** (direct and indirect)
+2. **Jailbreak attempts** (roleplay, emotional, paraphrasing, poetry)
+3. **System extraction** (rules, configuration, credentials)
+4. **Memory poisoning** (persistent malware, time-shifted)
+5. **Credential theft** (API keys, AWS/GCP/Azure, SSH)
+6. **Data exfiltration** (via tools, uploads, commands)
+
+### What Security Sentinel Does NOT Protect Against
+
+1. **Zero-day LLM exploits** (unknown techniques)
+2. **Physical access attacks** (if attacker has root, game over)
+3. **Supply chain attacks** (compromised dependencies - mitigated by open source review)
+4. **Social engineering of users** (skill can't prevent user from disabling security)
+
+---
+
