* Add security expansion: Skill signature verification + File integrity monitoring

Implements Phase 1 (Skill Signature Verification) and Phase 2 (File Integrity
Monitoring) for NanoClaw security enhancement.

## Phase 1: Skill Signature Verification (~490 lines)

Adds Ed25519 signature verification for skill packages to prevent supply chain attacks.

**New Files:**
- host-services/skill-signature-handler.ts (217 lines): Core verification service
- mcp-tools/signature-verification.ts (200 lines): clawsec_verify_skill_package tool
- docs/SKILL_SIGNING.md (270 lines): Complete signing/verification guide

- Package SHA-256 integrity hashing
- Fail-closed error handling with detailed diagnostics
- IPC-based container-to-host verification (5s timeout)

**MCP Tool:** clawsec_verify_skill_package
- Verifies skill packages before installation
- Returns: valid, recommendation (install/block/review), signer, algorithm
- Prevents installation of tampered/malicious packages

## Phase 2: File Integrity Monitoring (~1,765 lines)

Ports OpenClaw's soul-guardian to NanoClaw for critical file protection.

**New Files:**
- guardian/integrity-monitor.ts (711 lines): Core monitoring engine
- guardian/policy.json (55 lines): NanoClaw-specific protection policy
- mcp-tools/integrity-tools.ts (260 lines): 4 MCP tools for agents
- host-services/integrity-handler.ts (349 lines): IPC handler integration
- docs/INTEGRITY.md (470 lines): User documentation

**Features:**
- SHA-256 baseline tracking with tamper-evident audit logs
- Auto-restore for critical files (registered_groups.json, CLAUDE.md)
- Alert-only mode for non-critical files
- Intentional change approval workflow
- Hash-chained audit logging
- Symlink protection and atomic file operations
- Unified diff generation for drift analysis

**MCP Tools:**
- clawsec_check_integrity: Check files for unauthorized changes
- clawsec_approve_change: Approve legitimate modifications
- clawsec_integrity_status: View monitoring status
- clawsec_verify_audit: Verify audit log integrity

**Protected Files:**
- CRITICAL: registered_groups.json (prevents group hijacking)
- HIGH: CLAUDE.md files (prevents instruction poisoning)
- MEDIUM: Container/host code (alerts on changes)
- IGNORED: Conversations (expected to change)

## Shared Enhancements (+129 lines)

**Updated: lib/signatures.ts**
Added 5 new crypto utilities:
- verifyDetachedSignature(): File-based Ed25519 verification
- verifyDetachedSignatureWithDetails(): Diagnostic variant with error details
- loadPublicKey(): PEM validation and security enforcement
- sha256File(): File hashing (shared utility)
- verifyFileHashes(): Batch drift detection

**Updated: lib/types.ts**
Added TypeScript interfaces for:
- VerifySkillSignatureRequest/Response (Phase 1 IPC)
- IntegrityCheckRequest/Response (Phase 2 IPC)
- VerifySkillPackageParams (Phase 1 MCP tool)

**Updated: host-services/ipc-handlers.ts**
Added IPC handlers:
- verify_skill_signature (Phase 1)
- integrity_check, integrity_approve, integrity_status, integrity_verify_audit (Phase 2)

## Total Delivery

- **New Code**: ~2,958 lines
- **Files Created**: 11 new files

* Fix SKILL.md format: proper YAML frontmatter, remove ASCII diagrams, focus on when-to-use

* chore: align with contributors guidelines - set version 0.0.1, add version to SKILL.md frontmatter, complete SBOM

* fix: use specific NanoClaw repo URL instead of wildcard pattern

Change github.com/*/NanoClaw to github.com/qwibitai/NanoClaw to avoid
matching unrelated projects in CVE advisory scanning.

* docs: merge NanoClaw support into main README, move NANOCLAW.md to skill README

- Add NanoClaw platform section in main README
- Update supported platforms list (OpenClaw + NanoClaw)
- Add monitored keywords for NanoClaw (WhatsApp-bot, baileys)
- Document platform-specific advisory schema
- Move NANOCLAW.md to skills/clawsec-nanoclaw/README.md

* fix: resolve ESLint and TypeScript errors in clawsec-nanoclaw skill

Fix all CI failures from prepare-to-push.sh for the nanoclaw-integration branch:

ESLint fixes:
- Add missing Node.js globals (Buffer, AbortController, clearTimeout,
  RequestInit) to eslint.config.js for TypeScript files
- Add ambient declarations for host-provided variables (server, writeIpcFile,
  TASKS_DIR, groupFolder) in MCP tool template files
- Wrap bare case statements in ipc-handlers.ts in a proper exported function
- Replace @ts-ignore with @ts-expect-error in signatures.ts
- Prefix unused variables with underscore (affectedVersion, keyDer,
  safeBasename, groupFolder)
- Add eslint-disable directives for intentional any usage in template files
- Change any to unknown in types.ts where appropriate

TypeScript fixes:
- Replace glob import with ambient namespace declaration (glob not in repo deps)
- Fix Hash.hexdigest() to Hash.digest('hex') in integrity-monitor.ts
- Fix unreachable type comparison (recommendation === 'install') in
  advisory-tools.ts

Comment syntax fixes:
- Convert block comments containing '*/30 * * * *' cron expressions to
  line comments to prevent premature comment termination in
  integrity-handler.ts and integrity-tools.ts

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

* fix: implement missing MCP tools and align documentation with code

- Rewrote signature-verification.ts with actual server.tool() implementation (was template string)
- Fixed tool naming: clawsec_verify_signature -> clawsec_verify_skill_package
- Added missing clawsec_refresh_cache to all documentation
- Updated skill.json mcp_tools array from 4 to 9 tools (added Phase 1 & 2 tools)
- All 9 MCP tools now verified: 4 advisory + 1 signature + 4 integrity

# ClawSec for NanoClaw - Installation Guide
This guide shows how to add ClawSec security monitoring to your NanoClaw deployment.
## Overview
ClawSec provides security advisory monitoring for NanoClaw through:
- **MCP Tools**: Agents can check for vulnerabilities via `clawsec_check_advisories`
- **Advisory Feed**: Automatic monitoring of https://clawsec.prompt.security/advisories/feed.json
- **Signature Verification**: Ed25519-signed feeds ensure integrity
- **Platform Targeting**: Advisories can be NanoClaw-specific or cross-platform
## Prerequisites
- NanoClaw >= 0.1.0
- Node.js >= 18.0.0
- Write access to NanoClaw installation directory
## Installation Steps
### 1. Copy Skill Files
Copy the `clawsec-nanoclaw` skill directory to your NanoClaw installation:
```bash
# From the ClawSec repository
cp -r skills/clawsec-nanoclaw /path/to/your/nanoclaw/skills/
```
### 2. Integrate MCP Tools
Add the ClawSec MCP tools to your NanoClaw container agent runner.
**File**: `container/agent-runner/src/ipc-mcp-stdio.ts`
```typescript
// Add these imports at the top to register all ClawSec MCP tools:
// Advisory tools: clawsec_check_advisories, clawsec_check_skill_safety,
// clawsec_list_advisories, clawsec_refresh_cache
import '../../../skills/clawsec-nanoclaw/mcp-tools/advisory-tools.js';
// Signature verification: clawsec_verify_skill_package
import '../../../skills/clawsec-nanoclaw/mcp-tools/signature-verification.js';
// Integrity monitoring: clawsec_check_integrity, clawsec_approve_change,
// clawsec_integrity_status, clawsec_verify_audit
import '../../../skills/clawsec-nanoclaw/mcp-tools/integrity-tools.js';
```
Each file calls `server.tool()` directly to register its tools. The `server`,
`writeIpcFile`, `TASKS_DIR`, and `groupFolder` variables must be available in
the scope where these files are imported (they are declared as ambient globals
in each tool file).
### 3. Integrate IPC Handlers
Add the host-side IPC handlers for ClawSec operations.
**File**: `host/ipc-handler.ts`
```typescript
// Add this import at the top
import { registerClawSecHandlers } from '../skills/clawsec-nanoclaw/host-services/ipc-handlers.js';
// In your IPC handler setup function
export function setupIpcHandlers() {
// ... your existing handlers ...
// Register ClawSec handlers
registerClawSecHandlers();
}
```
### 4. Start Advisory Cache Service
Add the advisory cache manager to your host services.
**File**: `host/index.ts` (or your main entry point)
```typescript
// Add this import
import { startAdvisoryCache } from '../skills/clawsec-nanoclaw/host-services/advisory-cache.js';
// Start the service when your host process starts
async function main() {
// ... your existing initialization ...
// Start ClawSec advisory cache (fetches feed every 6 hours)
startAdvisoryCache({
cacheFile: '/workspace/project/data/clawsec-advisory-cache.json',
feedUrl: 'https://clawsec.prompt.security/advisories/feed.json',
publicKeyPath: '/workspace/project/skills/clawsec-nanoclaw/advisories/feed-signing-public.pem',
refreshInterval: 6 * 60 * 60 * 1000, // 6 hours
});
// ... rest of your startup ...
}
```
### 5. Restart NanoClaw
Restart your NanoClaw instance to load the new MCP tools and services:
```bash
# Stop NanoClaw
docker-compose down
# Start with new configuration
docker-compose up -d
```
## Verification
Test that ClawSec is working:
### 1. Check MCP Tools Available
From within a NanoClaw agent session, the following tools should be available:
**Advisory Tools** (mcp-tools/advisory-tools.ts):
- `clawsec_check_advisories` - Scan installed skills for vulnerabilities
- `clawsec_check_skill_safety` - Pre-installation safety check
- `clawsec_list_advisories` - List all advisories with filtering
- `clawsec_refresh_cache` - Request immediate advisory cache refresh
**Signature Verification** (mcp-tools/signature-verification.ts):
- `clawsec_verify_skill_package` - Verify Ed25519 signature on skill packages
**Integrity Monitoring** (mcp-tools/integrity-tools.ts):
- `clawsec_check_integrity` - Check protected files for unauthorized changes
- `clawsec_approve_change` - Approve intentional file modification as new baseline
- `clawsec_integrity_status` - View current baseline status
- `clawsec_verify_audit` - Verify audit log hash chain integrity
### 2. Test Advisory Checking
Ask your NanoClaw agent:
```
Check if any of my installed skills have security advisories
```
The agent should use the `clawsec_check_advisories` tool and report results.
### 3. Check Advisory Cache
Verify the cache file was created:
```bash
cat /workspace/project/data/clawsec-advisory-cache.json
```
You should see:
- `feed`: Array of advisories
- `signature`: Ed25519 signature
- `lastFetch`: Timestamp of last update
- `verified`: Should be `true`
## Usage Examples
### Agent Commands
Once installed, your NanoClaw agents can:
**Check for vulnerabilities:**
```
Scan my installed skills for security issues
```
**Pre-installation check:**
```
Is it safe to install skill-name@1.0.0?
```
**List all advisories:**
```
Show me all ClawSec security advisories
```
### Manual Tool Invocation
You can also call the MCP tools directly from agent code:
```typescript
// Check all installed skills
const result = await tools.clawsec_check_advisories({
skillsRoot: '/workspace/project/skills'
});
// Check specific skill before installation
const safetyCheck = await tools.clawsec_check_skill_safety({
skillName: 'risky-skill',
version: '1.0.0'
});
```
## Configuration
### Cache Location
Default: `/workspace/project/data/clawsec-advisory-cache.json`
To change, update the `cacheFile` parameter in `startAdvisoryCache()`.
### Refresh Interval
Default: 6 hours
To change, update the `refreshInterval` parameter (in milliseconds).
### Feed URL
Default: `https://clawsec.prompt.security/advisories/feed.json`
To use a mirror or custom feed, update the `feedUrl` parameter.
## Platform-Specific Advisories
ClawSec advisories can target specific platforms:
- **`platforms: ["nanoclaw"]`**: Only affects NanoClaw
- **`platforms: ["openclaw"]`**: Only affects OpenClaw/MoltBot
- **`platforms: ["openclaw", "nanoclaw"]`**: Affects both
- **No `platforms` field**: Applies to all platforms
The MCP tools automatically filter advisories based on your platform.
## Security
### Signature Verification
All advisory feeds are Ed25519 signed. The public key is pinned in:
```
skills/clawsec-nanoclaw/advisories/feed-signing-public.pem
```
Feeds failing signature verification are rejected.
### Cache Integrity
The advisory cache includes:
- Cryptographic signature of feed contents
- Verification status
- Timestamp of last successful fetch
Never manually edit the cache file - it will break signature verification.
## Troubleshooting
### Tools Not Appearing
**Problem**: MCP tools not showing up in agent
**Solution**:
1. Check that you added the import and registration in `ipc-mcp-stdio.ts`
2. Restart the container
3. Check container logs for import errors
### Cache Not Updating
**Problem**: Advisory cache is empty or stale
**Solution**:
1. Check that `startAdvisoryCache()` is called in your host entry point
2. Verify network access to `clawsec.prompt.security`
3. Check host logs for fetch errors
4. Manually trigger: `curl https://clawsec.prompt.security/advisories/feed.json`
### Signature Verification Failing
**Problem**: Cache shows `"verified": false`
**Solution**:
1. Ensure public key file exists at correct path
2. Check file permissions (should be readable)
3. Verify feed URL is correct (not using HTTP instead of HTTPS)
4. Check for corrupted downloads (try clearing cache and refetching)
### IPC Communication Issues
**Problem**: Tools return errors about IPC
**Solution**:
1. Verify IPC handlers are registered in `host/ipc-handler.ts`
2. Check that IPC directory exists and is writable
3. Ensure host process is running
4. Check host logs for handler errors
## Uninstallation
To remove ClawSec from NanoClaw:
1. Remove MCP tool registration from `ipc-mcp-stdio.ts`
2. Remove IPC handler registration from `host/ipc-handler.ts`
3. Remove `startAdvisoryCache()` call from host entry point
4. Delete the skill directory: `rm -rf skills/clawsec-nanoclaw`
5. Delete the cache file: `rm /workspace/project/data/clawsec-advisory-cache.json`
6. Restart NanoClaw
