# Security Assessment: Yatta! v0.2.1 (Metadata Fix)

**Version:** 0.2.1  
**Date:** 2026-02-28  
**Assessment Type:** Metadata and content improvements  
**Previous Version:** 0.2.0 (BENIGN per VirusTotal, SUSPICIOUS per ClawHub)  
**Issue:** #18

---

## Executive Summary

**v0.2.1 addresses ClawHub registry metadata issues that caused SUSPICIOUS rating despite VirusTotal BENIGN classification.**

### Changes

1. **Added top-level `disable-model-invocation: true` field** to SKILL.md frontmatter
2. **Declared optional verification tools** (`openssl`, `dig`) in `requires.anyBins`
3. **Updated description** to document v0.2.0 security fixes

### VirusTotal Confirmation

**v0.2.0 VirusTotal scan result: ✅ BENIGN**

> "The OpenClaw Yatta! skill (v0.2.0) is classified as benign. The developers have demonstrated a strong commitment to security by explicitly documenting and fixing critical shell and JSON injection vulnerabilities (RCE risk) present in previous versions."

**ClawHub scan issue:** Registry showed `disable-model-invocation: false` despite being set correctly in package.json and metadata JSON.

## Assessment Against ClawHub Security Criteria

### 1. Purpose-Capability Alignment

**Finding:** ✅ **NO CHANGE - BENIGN**

**Changes in v0.2.1:**
- Description now explicitly mentions security fixes
- No capability changes
- Clarifies historical vulnerability context

**Verdict:** BENIGN - Improved transparency

---

### 2. Instruction Scope

**Finding:** ✅ **NO CHANGE - BENIGN**

**Changes in v0.2.1:**
- No instruction changes
- Scope remains limited to Yatta! API
- Manual invocation only (now more explicit)

**Verdict:** BENIGN - No scope change

---

### 3. Install Mechanism Risk

**Finding:** ✅ **NO CHANGE - BENIGN**

**Changes in v0.2.1:**
- Added `anyBins: ["openssl", "dig"]` declaration
- These are optional tools (not mandatory)
- Standard system utilities
- No install risk introduced

**Verdict:** BENIGN - Better metadata accuracy

---

### 4. Environment/Credentials

**Finding:** ✅ **NO CHANGE - BENIGN**

**Changes in v0.2.1:**
- No credential changes
- Same API key requirements
- Verification script tools now properly declared

**Verdict:** BENIGN - No credential impact

---

### 5. Persistence & Privilege

**Finding:** ✅ **IMPROVED - BENIGN**

**Before v0.2.1:**
- ClawHub registry showed `disable-model-invocation: false`
- Potential for autonomous invocation if registry setting honored
- Metadata inconsistency

**After v0.2.1:**
- Top-level field added to SKILL.md
- Follows same pattern as Gandi (BENIGN/BENIGN)
- Registry should now correctly reflect manual-only policy

**Verdict:** BENIGN - Metadata consistency improved

---

## Changes Analysis

### Change 1: Top-Level Field

**What changed:**
```yaml
# Before (v0.2.0)
---
name: yatta
description: "..."
metadata: {"openclaw":{"disable-model-invocation":true,...}}
---

# After (v0.2.1)
---
name: yatta
description: "..."
disable-model-invocation: true  # ← Added top-level field
metadata: {"openclaw":{"disable-model-invocation":true,...}}
---
```

**Why:**
- ClawHub registry parser appears to read top-level frontmatter field
- Gandi (BENIGN/BENIGN) uses this pattern
- Ghost CMS (BENIGN/BENIGN) doesn't use it but somehow works
- Adding it eliminates ambiguity

**Security impact:** ✅ None (clarifies existing policy)

---

### Change 2: Optional Tools Declaration

**What changed:**
```json
"requires": {
  "bins": ["curl", "jq"],
  "anyBins": ["openssl", "dig"]  // ← Added
}
```

**Why:**
- `scripts/verify-endpoint.sh` uses these tools
- ClawHub scanner noted they weren't declared
- `anyBins` = optional (skill works without them)
- Verification script gracefully handles missing tools

**Security impact:** ✅ None (improves metadata accuracy)

---

### Change 3: Description Update

**What changed:**
```
Before: "Personal productivity system... to prevent overcommitment."

After: "Personal productivity system... to prevent overcommitment. 
        Security: v0.2.0 eliminates RCE vulnerability from v0.1.3 
        (shell/JSON injection in examples), adds endpoint verification, 
        safe jq patterns throughout."
```

**Why:**
- Documents security evolution
- Similar to Tide Watch documenting CVE-2026-001
- Helps users understand what was fixed and when
- Transparency about vulnerability history

**Security impact:** ✅ Positive (educational, transparent)

---

## Metadata Consistency Verification

### v0.2.1 Status

**package.json:**
```json
"openclaw": {
  "disable-model-invocation": true  // ✅ Set
}
```

**SKILL.md frontmatter (top-level):**
```yaml
disable-model-invocation: true  // ✅ Set (NEW in v0.2.1)
```

**SKILL.md metadata JSON:**
```json
"metadata": {"openclaw":{"disable-model-invocation":true}}  // ✅ Set
```

**All three locations consistent:** ✅

---

## Overall Security Classification

### Self-Assessment

**Classification:** ✅ **BENIGN** (High Confidence)

**Rationale:**

1. **Metadata improvements only** - No code changes
2. **Follows BENIGN skill pattern** - Same structure as Gandi
3. **Better transparency** - Documents security fixes
4. **Tool declarations accurate** - Optional tools properly declared
5. **No new risks** - Documentation/metadata only

### Confidence Factors

**High confidence because:**
- ✅ v0.2.0 already assessed as BENIGN (all vulnerabilities fixed)
- ✅ VirusTotal confirmed BENIGN for v0.2.0
- ✅ v0.2.1 only adds metadata clarity
- ✅ No capability expansion
- ✅ No code changes
- ✅ Follows proven BENIGN skill pattern

## Comparison: v0.2.0 vs v0.2.1

### Security Ratings

**v0.2.0:**
- VirusTotal: **BENIGN** ✅
- ClawHub: **SUSPICIOUS** (metadata issue)

**v0.2.1:**
- VirusTotal: **BENIGN** (expected, no code changes)
- ClawHub: **BENIGN** (expected, metadata fixed)

### Metadata Consistency

**v0.2.0:**
- package.json: ✅ `disable-model-invocation: true`
- SKILL.md frontmatter: ❌ Missing top-level field
- SKILL.md metadata: ✅ `disable-model-invocation: true`

**v0.2.1:**
- package.json: ✅ `disable-model-invocation: true`
- SKILL.md frontmatter: ✅ `disable-model-invocation: true`
- SKILL.md metadata: ✅ `disable-model-invocation: true`

### Tool Declarations

**v0.2.0:**
- Required: `curl`, `jq`
- Optional: ❌ Not declared (but used by verification script)

**v0.2.1:**
- Required: `curl`, `jq`
- Optional: ✅ `openssl`, `dig` (properly declared)

---

## Recommendations

### For Publication

**✅ READY TO PUBLISH TO CLAWHUB**

**Expected outcome:**
- ClawHub scan: SUSPICIOUS → BENIGN
- VirusTotal scan: BENIGN (unchanged)
- Registry metadata: Correctly reflects manual-only policy

**Publication command:**
```bash
clawhub publish ~/clawd/openclaw-yatta-skill \
  --slug openclaw-yatta-skill \
  --name "Yatta! - Task & Capacity Management" \
  --version 0.2.1 \
  --changelog "Metadata fix: Add top-level disable-model-invocation field, declare optional verification tools (openssl, dig), update description to document v0.2.0 security fixes"
```

### For Users

**Migration from v0.2.0:**
- No action required
- Update: `clawhub update openclaw-yatta-skill`
- No breaking changes
- Same functionality

### For Maintenance

**Going forward:**
- Always include top-level `disable-model-invocation` field for skills with destructive operations
- Declare all tools used by scripts (even optional ones) in `requires.anyBins`
- Document security fixes in skill description (transparency pattern)

---

## Conclusion

**v0.2.1 successfully addresses ClawHub metadata issues.**

**Security status:**
- Code: Unchanged from v0.2.0 (BENIGN)
- Metadata: Fixed (top-level field added)
- Transparency: Improved (security fixes documented)

**Expected ratings:**
- VirusTotal: BENIGN (confirmed for v0.2.0, expected for v0.2.1)
- ClawHub: BENIGN (metadata fix should resolve SUSPICIOUS rating)

**Ready for production use.**
