description: >
  Autonomously scans all installed OpenClaw skills for security risks.
  Detects dangerous behaviors like shell execution, file deletion, remote code
  download, data exfiltration, and obfuscated logic. Assigns each skill a risk
  score (0–100), risk level (Low/Medium/High), and generates a full security
  report with mitigation recommendations.
  Use this when the user asks to audit skills, check for security risks,
  scan installed skills, or wants a security report.

# Security Auditor (Autonomous)

You are acting as an autonomous security engineer. Your job is to statically
analyze all installed OpenClaw skills and produce a detailed security report.

## When to activate

- User says "audit my skills", "scan skills for security issues", "check skill safety"
- User asks "are my skills safe?", "which skills are risky?"
- User wants to review a specific skill: "audit the X skill"
- A new skill was just installed and the user wants it checked
- User asks for a "security report" or "risk assessment"

## Workflow

Follow these steps in order. Do not skip steps.

### Step 1 — Discover installed skills

Scan all three skill locations in priority order:
1. `<workspace>/skills/` (workspace-local)
2. `~/.openclaw/skills/` (user-global)
3. OpenClaw bundled skills directory (read-only, lower priority)

For each location, list all subdirectories. Each subdirectory is a skill.
Record: skill name, source location, full path.

### Step 2 — Parse each skill

For every discovered skill directory, read:
- `SKILL.md` — extract frontmatter (name, description, metadata, permissions)
  and the full Markdown body (instructions, examples, tool calls)
- `scripts/` — read all files (`.js`, `.ts`, `.py`, `.sh`, `.bash`, any executable)
- Any other files present (`.json` config, `.env` templates, README, etc.)

If a file cannot be read, note it as "unreadable — treat as elevated risk."

### Step 3 — Run the analysis engine

For each skill, apply ALL rules from the rule set below.
Accumulate a risk score and collect all triggered findings.

---

## Rule Set

### HIGH RISK rules (each adds 25–40 points)

**H1 — Shell execution**
Patterns: `exec(`, `execSync(`, `spawn(`, `spawnSync(`, `child_process`,
`subprocess`, `os.system(`, `os.popen(`, `eval(`, `Function(`, `sh -c`,
`bash -c`, `cmd /c`, backtick execution in shell scripts.
Finding: "Executes shell commands — can run arbitrary OS-level code."

**H2 — Remote code download + execute**
Patterns: `curl ... | sh`, `wget ... | bash`, `fetch(` or `axios` combined
with `eval` or `exec`, dynamic `import()` from a URL, `require(url)`.
Finding: "Downloads and executes remote code — supply chain attack vector."

**H3 — Arbitrary file deletion**
Patterns: `fs.unlink`, `fs.rm(`, `rimraf`, `rm -rf`, `shutil.rmtree`,
`os.remove(`, `unlink(` outside of a clearly scoped temp directory.
Finding: "Can delete files — potential for destructive data loss."

**H4 — Obfuscated or encoded logic**
Patterns: `Buffer.from(..., 'base64')` followed by `eval`, `atob(` + `eval`,
long hex/base64 strings (>200 chars) decoded at runtime, `\\x` escape sequences
in executable strings, minified one-liners over 500 chars with no comments.
Finding: "Contains obfuscated logic — hides true behavior from static analysis."

**H5 — Privilege escalation**
Patterns: `sudo `, `su -`, `chmod 777`, `chown root`, `setuid`, `pkexec`.
Finding: "Attempts privilege escalation — can gain elevated OS permissions."

**H6 — Credential/secret harvesting**
Patterns: reads `~/.ssh/`, `~/.aws/credentials`, `~/.config/`, `~/.gnupg/`,
`/etc/passwd`, `~/.netrc`, `~/.npmrc`, `~/.pypirc`, env vars containing
`TOKEN`, `SECRET`, `PASSWORD`, `KEY`, `CREDENTIAL` sent to external URLs.
Finding: "Accesses credential stores — high risk of secret exfiltration."

**H7 — .env file access**
Patterns: `readFileSync('.env')`, `open('.env')`, `require('dotenv')`, `dotenv`.
Finding: "Reads .env files — may expose all secrets stored in the environment file."

**H8 — Keylogger / input capture**
Patterns: `keypress`, `GetAsyncKeyState`, `pynput`, `keyboard.on_press`, `process.stdin.setRawMode(true)`.
Finding: "Captures keyboard input — potential keylogger, passwords and input silently recorded."

**H9 — Clipboard access**
Patterns: `clipboard`, `xclip`, `pbpaste`, `pyperclip`, `navigator.clipboard`, `GetClipboardData`.
Finding: "Accesses system clipboard — copied passwords, tokens, or secrets may be stolen."

**H10 — Screenshot / screen capture**
Patterns: `screencapture`, `screenshot`, `PIL.ImageGrab`, `pyautogui.screenshot`, `getDisplayMedia(`.
Finding: "Captures screen content — visual data, credentials, and private content may be exfiltrated."

**H11 — Crypto mining indicators**
Patterns: `stratum+tcp://`, `xmrig`, `monero`, `cryptonight`, `hashrate`, `mining pool`.
Finding: "Crypto mining indicators — unauthorized use of host CPU/GPU resources."

**H12 — Reverse shell / backdoor**
Patterns: `nc -e /bin/sh`, `bash -i >& /dev/tcp/`, `/dev/tcp/`, `pty.spawn`, `IEX(New-Object Net.WebClient)`.
Finding: "Reverse shell patterns — may grant full remote access to the host machine."

**H13 — Windows registry manipulation**
Patterns: `winreg`, `HKEY_`, `RegSetValue`, `reg add`, `HKLM\Software\Microsoft\Windows\CurrentVersion\Run`.
Finding: "Registry manipulation — can install persistent malware or modify system behavior."

**H14 — Persistence mechanism**
Patterns: `crontab -e`, `launchctl load`, `systemctl enable`, writes to `~/.bashrc`, `~/.zshrc`, `~/.profile`, `schtasks /create`.
Finding: "Installs persistence — skill or payload survives reboots and user sessions."

---

### MEDIUM RISK rules (each adds 10–20 points)

**M1 — External network calls**
Patterns: `fetch(`, `axios`, `http.get`, `https.get`, `curl`, `wget`,
`requests.get`, `urllib` to non-localhost URLs.
Finding: "Makes external network requests — data may leave the machine."

**M2 — Sensitive directory access**
Patterns: reads from `~/Documents`, `~/Desktop`, `~/Downloads`, `~/.ssh`,
`~/.config`, `/etc/`, `/var/`, `$HOME` combined with credential file names.
Finding: "Accesses sensitive directories — may read private user data."

**M3 — Data exfiltration pattern**
Patterns: reads local files AND makes outbound HTTP/S calls in the same script,
POST requests with file content, `FormData` with file attachments sent externally.
Finding: "Read-then-send pattern detected — potential data exfiltration."

**M4 — Dynamic code construction**
Patterns: `eval(`, `new Function(`, `vm.runInNewContext(`, `vm.runInThisContext(`,
template literals used as code strings passed to exec.
Finding: "Constructs and runs code dynamically — behavior depends on runtime input."

**M5 — Excessive permission claims**
Skill declares permissions beyond what its described behavior requires.
E.g., a "weather lookup" skill that claims `write:filesystem` or `exec:shell`.
Finding: "Declared permissions exceed stated functionality — principle of least privilege violated."

**M6 — Unscoped file writes**
Patterns: `fs.writeFile(`, `fs.appendFile(` to paths outside a clearly defined
working directory, writing to `~/.openclaw/`, `~/.config/`, system directories.
Finding: "Writes files outside expected scope — may tamper with system or agent config."

**M7 — Denial-of-service patterns**
Patterns: `while(true)` with no break, `for(;;)` with no break, deeply recursive
functions without base case, `process.exit()` with unexpected codes.
Finding: "Contains patterns that could hang or crash the agent process."

**M8 — Browser storage / cookie access**
Patterns: `document.cookie`, `localStorage`, `sessionStorage`, `indexedDB`, `chrome.cookies`.
Finding: "Accesses browser cookies or local storage — session hijacking risk."

**M9 — WebSocket connection (potential C2)**
Patterns: `new WebSocket(`, `wss://`, `ws://`, `require('ws')`, `require('socket.io')`.
Finding: "Opens persistent WebSocket — may serve as a command-and-control channel."

**M10 — DNS lookup / hostname resolution**
Patterns: `dns.lookup(`, `dns.resolve(`, `socket.gethostbyname(`, `nslookup`, `dig `.
Finding: "Performs DNS lookups — may be used for DNS exfiltration or C2 beaconing."

**M11 — Process enumeration**
Patterns: `ps aux`, `tasklist`, `psutil.process_iter`, `os.listdir('/proc')`, `/proc/<pid>/cmdline`.
Finding: "Enumerates running processes — reconnaissance of the host environment."

**M12 — Network interface enumeration**
Patterns: `ifconfig`, `ipconfig`, `ip addr`, `netifaces`, `os.networkInterfaces()`.
Finding: "Enumerates network interfaces — host network reconnaissance."

**M13 — File archiving before send (staging)**
Patterns: `tar czf`, `zip -r`, `zipfile`, `tarfile`, `shutil.make_archive`, `AdmZip`, `archiver`.
Finding: "Archives files before network calls — strong exfiltration staging signal."

**M14 — Sleep / timing evasion**
Patterns: `time.sleep(` with >30s delay, `setTimeout` with >30s delay before payload.
Finding: "Long sleep delays before execution — may be evading sandbox time limits."

**M15 — Self-modification / self-deletion**
Patterns: `__file__` used in `unlink`/`remove`, `argv[0]` used in `writeFile`/`unlink`.
Finding: "Script modifies or deletes itself — anti-forensics or self-updating malware pattern."

**M16 — Cloud metadata endpoint access (IMDS)**
Patterns: `169.254.169.254`, `metadata.google.internal`, `169.254.170.2`, `metadata.azure.internal`.
Finding: "Queries cloud instance metadata — IAM credentials and secrets may be stolen."

---

### LOW RISK rules (each adds 1–8 points)

**L1 — Telemetry / logging to external service**
Patterns: sends logs, errors, or usage data to a remote endpoint.
Finding: "Sends telemetry externally — usage data may be collected."

**L2 — Third-party API dependency**
Patterns: calls to known third-party APIs (OpenAI, Stripe, Twilio, SendGrid, etc.)
Finding: "Depends on third-party API — availability and data handling outside your control."

**L3 — Reads environment variables**
Patterns: `process.env.`, `os.environ`, `$ENV_VAR` in scripts.
Finding: "Reads environment variables — may access secrets stored in env."

**L4 — No description or sparse SKILL.md**
SKILL.md body is under 50 words or missing key sections (When to use, Input, Output).
Finding: "Sparse documentation — intent and behavior are unclear."

**L5 — Hardcoded URLs or IPs**
Patterns: hardcoded `http://` or `https://` URLs, IP addresses in scripts.
Finding: "Contains hardcoded endpoints — behavior tied to specific external services."

**L6 — TODO/FIXME security notes**
Patterns: `// TODO.*security`, `// FIXME.*auth`, `HACK`, `// XXX.*password`.
Finding: "Security-related TODO/FIXME comments — known unresolved security issues in code."

**L7 — Weak cryptography**
Patterns: `md5(`, `sha1(`, `createHash('md5')`, `createHash('sha1')`, `DES`, `RC4`,
`Math.random()` used for token/key/secret generation.
Finding: "Uses weak or broken cryptographic algorithms — vulnerable to collision or brute-force."

**L8 — Insecure HTTP (non-TLS)**
Patterns: `http://` URLs to non-localhost hosts.
Finding: "Makes unencrypted HTTP connections — data in transit is not protected."

**L9 — Debug / development artifacts**
Patterns: `console.log` with password/secret/token, `print(` with credential keywords,
`debugger;`, `pdb.set_trace()`, `ipdb.set_trace()`.
Finding: "Debug artifacts left in code — may leak sensitive values to logs."

**L10 — Large file size anomaly**
Script files over 500KB are flagged — unusually large scripts may contain embedded payloads,
bundled binaries, or obfuscated data blobs.
Finding: "Unusually large script file — possible embedded payload or binary data."

---

## Scoring

Sum all triggered rule scores. Cap at 100.

| Score | Level  |
|-------|--------|
| 0–29  | Low    |
| 30–59 | Medium |
| 60+   | High   |

Bonus escalation: if H2 (remote execute) OR H4 (obfuscation) fires,
automatically set level to High regardless of total score.

---

## Step 4 — Malicious simulation

For each skill with score ≥ 30, generate a "what-if malicious" scenario.
Based on the permissions and code patterns found, describe the worst-case
abuse. Be specific. Examples:

- "If this skill were weaponized, it could read all files in ~/Documents
  and POST them to an attacker-controlled server using the existing fetch() call."
- "The shell exec pattern could be used to run `rm -rf ~/` or install a backdoor."
- "The base64 eval pattern could decode and run any payload injected at runtime."

Keep simulations grounded in what the code actually does — no speculation
beyond observed patterns.

---

## Step 5 — Recommended actions

For each skill, suggest concrete mitigations:

- **Disable**: if score ≥ 80 or H2/H4 fires — recommend immediate disable
- **Restrict**: suggest removing specific permissions from metadata
- **Sandbox**: recommend running in Docker sandbox if shell/network patterns found
- **Review**: for medium risk, ask the user to manually review flagged lines
- **Whitelist**: if skill is known-good (e.g., bundled official skill with no risky patterns),
  suggest adding to whitelist to suppress future alerts
- **Replace**: suggest a safer alternative approach if one exists

---

## Step 6 — Output the report

Format the report exactly as follows:

```
╔══════════════════════════════════════════════════════════════╗
║           OPENCLAW SECURITY AUDIT REPORT                     ║
║           Generated: <timestamp>                             ║

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

[Repeat for each skill, ordered High → Medium → Low]

Skill Name    : <name>

───────────────────────────────────────────────────────────────
```

After the per-skill sections, append:

```

Skills with score 0 and no triggered rules:
  • <skill name> — safe to whitelist

SECURITY HISTORY NOTE
─────────────────────
Save this report to ~/.openclaw/security-reports/<YYYY-MM-DD>.md
to maintain an audit trail. Re-run after installing new skills.
```

---

## Auditing a single skill

If the user asks to audit one specific skill by name:
- Run Steps 2–5 for that skill only
- Output the single-skill section of the report format
- Still show the malicious simulation if score ≥ 30

---

## Continuous monitoring guidance

Tell the user:
"Run `node scripts/monitor.js` as a background process to watch
~/.openclaw/skills/ for changes and re-audit automatically.
Use `node scripts/monitor.js --alert-only` to only print on High risk findings."

## CLI usage (for reference)

When the user asks how to run the auditor directly:
```
node scripts/audit.js --dir <skills-path>          # scan a directory
node scripts/audit.js --skill <name>               # single skill
node scripts/audit.js --output json                # JSON output
node scripts/audit.js --output markdown            # Markdown report
node scripts/audit.js --save                       # save to history
node scripts/audit.js --compare                    # diff vs last report
node scripts/audit.js --fix                        # patch dangerous permissions
node scripts/audit.js --trust                      # show trust score history
node scripts/test.js                               # run test suite
```

---

## Important constraints

- NEVER execute any skill code. Analysis is static only.
- NEVER modify or delete any skill files during analysis.
- If you cannot read a file, flag it as unreadable and assign +15 risk points.
- Do not produce false positives for comments — only flag executable code patterns.
- If a pattern appears only in a comment or string literal that is never executed,
  note it as "pattern in comment — lower confidence" and reduce score contribution by 50%.
- Be precise: quote the actual line or pattern that triggered each rule.

FILE:README.md
# Security Auditor — OpenClaw Skill

Autonomously scans all installed OpenClaw skills for security risks using
static analysis. No skill code is ever executed.

## Installation

```bash
# Copy to your OpenClaw skills directory
cp -r security-auditor ~/.openclaw/skills/security-auditor

# Or for workspace-local use
cp -r security-auditor ./skills/security-auditor
```

## Dashboard (GUI)

Run the local web dashboard for a visual risk overview:

```bash
node scripts/dashboard.js
# or point at a specific skills directory:
node scripts/dashboard.js --dir data/sample-skills
# custom port:
node scripts/dashboard.js --port 8080
# skip auto-opening the browser:
node scripts/dashboard.js --no-open
```

Opens `http://localhost:7777` automatically. No build step, no npm install — pure Node.js stdlib on the server, vanilla JS in the browser.

Features:
- Live risk summary (total / high / medium / low counts)
- Expandable skill cards with score ring, triggered rules, threats, simulation, recommendations
- Trust score bar per skill
- Filter by risk level, search by name or behavior
- Whitelist toggle directly from the UI (re-scans automatically)



Once installed, just ask your agent:

```
"Audit all my installed skills"
"Are my skills safe?"
"Run a security scan on the file-cleaner skill"
"Give me a security report"
```

## Usage via CLI (direct)

```bash
# Scan all skills (default paths)
node scripts/audit.js

# Scan a specific directory of skills
node scripts/audit.js --dir data/sample-skills

# Scan a single skill by name
node scripts/audit.js --dir data/sample-skills --skill file-cleaner

# Output formats
node scripts/audit.js --dir data/sample-skills --output json      # machine-readable
node scripts/audit.js --dir data/sample-skills --output markdown  # Markdown report
node scripts/audit.js --dir data/sample-skills --output csv       # CSV export

# Filter by severity
node scripts/audit.js --severity high     # only High risk skills
node scripts/audit.js --severity medium   # only Medium risk skills

# Save report to ~/.openclaw/security-reports/
node scripts/audit.js --dir data/sample-skills --save

# Compare against last saved report (shows what changed)
node scripts/audit.js --dir data/sample-skills --compare

# Auto-generate patched SKILL.md with dangerous permissions stripped
node scripts/audit.js --dir data/sample-skills --fix

# Show trust score history for all skills
node scripts/audit.js --trust

# Show rule-frequency analytics
node scripts/audit.js --dir data/sample-skills --stats

# Manage the whitelist
node scripts/whitelist.js add weather-lookup
node scripts/whitelist.js list
node scripts/whitelist.js remove weather-lookup

# Continuous monitoring (background watcher)
node scripts/monitor.js
node scripts/monitor.js --alert-only   # only print on High risk

# Run the test suite
node scripts/test.js
```

## Testing with sample skills

```bash
node scripts/audit.js --dir data/sample-skills
```

> **Note:** `data/sample-skills/` contains intentionally risky demo scripts used
> to validate the auditor's detection rules. They are not needed for normal use
> and can be safely deleted if you do not want potentially dangerous demo code on disk:
> ```bash
> rm -rf data/sample-skills
> ```

See `data/example-output.md` for expected output against the three sample skills.

## Continuous monitoring (optional, advanced)

> ⚠️ **This is an optional feature.** Running the monitor as a background service
> means it will continuously read skill files and run on every login. Only enable
> this if you have reviewed the code and are comfortable with that behavior.

Run the monitor script in the background to auto-audit whenever a skill file changes:

```bash
node scripts/monitor.js
# or, only alert on High risk findings:
node scripts/monitor.js --alert-only
```

If you choose to run it automatically on login, the recipes below show how.
**Review the code first and only proceed if you trust the package source.**

**launchd (macOS)** — create `~/Library/LaunchAgents/com.openclaw.security-monitor.plist`:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>com.openclaw.security-monitor</string>
  <key>ProgramArguments</key>
  <array>
    <string>/usr/bin/node</string>
    <string>/path/to/security-auditor/scripts/monitor.js</string>
    <string>--alert-only</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>StandardOutPath</key>
  <string>/tmp/openclaw-monitor.log</string>
  <key>StandardErrorPath</key>
  <string>/tmp/openclaw-monitor.log</string>
</dict>
</plist>
```
Then: `launchctl load ~/Library/LaunchAgents/com.openclaw.security-monitor.plist`

**systemd (Linux)** — create `~/.config/systemd/user/openclaw-monitor.service`:
```ini
[Unit]
Description=OpenClaw Security Monitor

[Service]
ExecStart=/usr/bin/node /path/to/security-auditor/scripts/monitor.js --alert-only
Restart=on-failure

[Install]
WantedBy=default.target
```
Then: `systemctl --user enable --now openclaw-monitor`

## Risk scoring

| Score | Level  | Meaning                                      |
|-------|--------|----------------------------------------------|
| 0–29  | 🟢 Low  | Benign — review optional                    |
| 30–59 | 🟡 Medium | Warrants manual review before trusting    |
| 60+   | 🔴 High | Disable or sandbox immediately              |

H2 (remote code execute) or H4 (obfuscation) always forces High regardless of score.

## Detection rules (v3)

44 rules across 3 risk levels:

High risk (H1–H16): shell execution, remote code download, file deletion, obfuscation, privilege escalation, credential harvesting, .env access, keyloggers, clipboard theft, screen capture, crypto mining, reverse shells, registry manipulation, persistence mechanisms, SQL/command injection, supply-chain/runtime package install

Medium risk (M1–M20): network calls, sensitive directory access, data exfiltration, dynamic eval, permission mismatch, unscoped writes, DoS patterns, browser storage, WebSocket C2, DNS lookups, process enumeration, network enumeration, file archiving/staging, timing evasion, self-modification, cloud IMDS access, prototype pollution, path traversal, unsafe deserialization, hardcoded credentials

Low risk (L1–L10): telemetry, third-party APIs, env var reads, sparse docs, hardcoded URLs, security TODOs, weak crypto, insecure HTTP, debug artifacts, large file anomaly

Plus: Shannon entropy analysis (H4e) — detects high-entropy strings that may be embedded secrets or encoded payloads

## New features (v2/v3)

- `--dir <path>` — scan any directory of skills
- `--output markdown` — Markdown report
- `--output csv` — CSV export (one row per skill, importable into spreadsheets)
- `--compare` — diff current scan against last saved report
- `--fix` — auto-generate `SKILL.patched.md` with dangerous permissions stripped
- `--trust` — display trust score history with trend indicators
- `--stats` — rule-frequency analytics: which rules fire most, average risk score
- `--severity high|medium|low` — filter output to one risk level
- Shannon entropy analysis (H4e) — catches embedded secrets/payloads not caught by base64 patterns
- Rules H15–H16 — SQL/command injection, supply-chain/runtime package install
- Rules M17–M20 — prototype pollution, path traversal, unsafe deserialization, hardcoded credentials
- `scoreBreakdown` field in JSON output — per-rule score contribution
- Dashboard: Stats tab with rule-frequency bar chart
- Dashboard: Score breakdown section per skill card
- Dashboard: Risk trend sparkline on each card (from trust history)
- Dashboard: CSV export button (⬇ CSV in header)
- Dashboard: `R` keyboard shortcut to rescan
- Dashboard: Search now matches rule IDs and labels too
- Dashboard: `POST /api/scan/single` — re-scan one skill by name
- Dashboard: `GET /api/stats` — rule frequency analytics endpoint
- Dashboard: `GET /api/export/csv` — CSV download endpoint

## Constraints

- Static analysis only — no skill code is ever executed
- Read-only — never modifies or deletes skill files
- No external dependencies — pure Node.js stdlib

Location      : data/sample-skills/file-cleaner
Risk Score    : 90 / 100
Risk Level    : 🔴 High

Detected Behaviors:
  • Executes shell commands
  • Deletes files from the filesystem
  • Makes outbound network requests
  • Reads files and sends data externally (exfiltration pattern)
  • Claims permissions beyond stated functionality
  • Includes 1 executable script file(s)

Triggered Rules:
  • [H1] Shell execution — run.js: `execSync(`
  • [H3] Arbitrary file deletion — run.js: `rm -rf`; run.js: `fs.unlink(`
  • [M1] External network calls — run.js: `fetch("https://analytics.example.com/track"`
  • [M3] Data exfiltration pattern — run.js: `fetch(` combined with file operations
  • [M5] Excessive permission claims — Claims: [write:filesystem, exec:shell, network:unrestricted] but description suggests benign use
  • [L3] Reads environment variables — run.js: `os.homedir()`
  • [L5] Hardcoded URLs or IPs — run.js: `https://analytics.example.com/track`

Potential Threats:
  • Arbitrary OS command execution on the host machine
  • Irreversible data loss through file deletion
  • Sensitive file contents leaked to external server
  • Automated data exfiltration of local files

Malicious Simulation:
  ⚠ Shell execution + file deletion means "file-cleaner" could run `rm -rf ~/`
    or selectively wipe project files, databases, or SSH keys with no recovery
    path.
  ⚠ The read-then-send pattern in "file-cleaner" could be used to enumerate
    files in ~/Documents or ~/Desktop and silently upload them to an external
    endpoint, exfiltrating personal data, source code, or business documents.

Recommended Actions:
  → DISABLE immediately — risk level is critical. Remove or quarantine this skill.
  → Run in Docker sandbox mode to isolate shell execution from the host OS.
  → Review all outbound HTTP calls — verify destination URLs are expected and trusted.
  → Scope file deletion to a specific temp directory; never allow deletion of arbitrary paths.

Skill Name    : data-sync
Location      : data/sample-skills/data-sync
Risk Score    : 48 / 100
Risk Level    : 🟡 Medium

Detected Behaviors:
  • Makes outbound network requests
  • Reads from sensitive system directories
  • Reads files and sends data externally (exfiltration pattern)
  • Reads environment variables
  • Hardcoded URLs or IP addresses
  • Includes 1 executable script file(s)

Triggered Rules:
  • [M1] External network calls — sync.py: `urllib.request`
  • [M2] Sensitive directory access — sync.py: `~/Documents`
  • [M3] Data exfiltration pattern — sync.py: reads files then POSTs to remote URL
  • [L3] Reads environment variables — sync.py: `os.environ.get("BACKUP_TOKEN")`; `os.environ.get("HOME")`
  • [L5] Hardcoded URLs or IPs — sync.py: `https://backup.example.com/upload`

Potential Threats:
  • Sensitive file contents leaked to external server
  • Automated data exfiltration of local files
  • Exposure of secrets stored in environment variables

Malicious Simulation:
  ⚠ With its current permission set, a malicious version of "data-sync" could
    abuse its network or file access to leak data or disrupt local workflows.
    Specifically: it reads all files from ~/Documents and POSTs them — including
    any .env files, SSH configs, or source code — to backup.example.com. If that
    domain were attacker-controlled, all content would be exfiltrated silently.

Recommended Actions:
  → Review all outbound HTTP calls — verify destination URLs are expected and trusted.
  → Review flagged patterns manually before trusting this skill in production.

# Data Sync

Backs up local project files to a configured remote server.

## When to use

# Weather Lookup

Fetches current weather for a given city using the free Open-Meteo API.
No API key required.

## When to use
- User asks "what's the weather in X?"
- User asks about temperature, rain, or forecast for a location

## Input
city: string — city name (e.g. "London", "Tokyo")

## Output
JSON with temp (°C), condition, humidity, wind speed

## How it works
1. Geocode the city name to lat/lon via Open-Meteo geocoding API
2. Fetch current weather from Open-Meteo forecast API
3. Return formatted result

## Example
User: "What's the weather in Paris?"
→ Calls weather API for Paris coordinates
→ Returns: { city: "Paris, France", temp: "18°C", condition: "Partly cloudy" }

## Notes
- Uses only public, free APIs — no authentication needed
- Read-only — does not write any files
- No shell commands used

 * OpenClaw Security Auditor — Core Analysis Engine v3
 * Static analysis only. Never executes skill code.
 *
 * Usage:
 *   node audit.js                         # scan all default skill paths
 *   node audit.js --dir <path>            # scan skills in a specific directory
 *   node audit.js --skill <name>          # scan one skill by name
 *   node audit.js --output json           # machine-readable JSON output
 *   node audit.js --output markdown       # Markdown-formatted report
 *   node audit.js --output csv            # CSV export (one row per skill)
 *   node audit.js --save                  # save report to ~/.openclaw/security-reports/
 *   node audit.js --compare               # diff against last saved report
 *   node audit.js --fix                   # generate patched SKILL.md with risky perms stripped
 *   node audit.js --trust                 # show trust score history for all skills
 *   node audit.js --stats                 # show rule-frequency analytics across all skills
 *   node audit.js --severity high         # only show High risk skills
 *   node audit.js --severity medium       # only show Medium risk skills
 *   node audit.js --severity low          # only show Low risk skills
