runtime-sentinel
Runtime security guardian for OpenClaw agents — skill integrity hashing, prompt injection detection, credential exposure auditing, network egress monitoring, and process anomaly detection.
runtime-sentinel is a legitimate security auditing tool, but its SKILL.md omits critical capability declarations — shell execution (unzip), process access (walk all /proc), network calls to multiple external services, and local wallet key storage. No malicious behavior found.

可以安装
Add complete capability declarations to SKILL.md frontmatter: declare network destinations (VirusTotal, ClawHub, api.runtime-sentinel.dev, mainnet.base.org, x402.org/facilitator), shell:WRITE for unzip during skill extraction, and document wallet storage at ~/.sentinel/. The skill's behavior is defensively legitimate but the documentation mismatch creates risk of false negatives in a ClawSafe audit.

SKILL.md omits network access declaration 文档欺骗
The skill makes HTTP requests to at least 5 external domains (api.runtime-sentinel.dev, clawhub.ai, virustotal.com, x402.org, mainnet.base.org) but SKILL.md declares zero network access and only mentions x402 payment flow as a concept without listing endpoints.
SKILL.md frontmatter: compatibility: { binaries: [sentinel], env: [SENTINEL_WALLET, SENTINEL_RPC, SENTINEL_VT_KEY] } — no network declaration
→ Add network declarations to SKILL.md frontmatter: list all API endpoints, VirusTotal domain, ClawHub domains, Base RPC, and x402 facilitator as declared destinations.
 SKILL.md:1
中危
SKILL.md omits shell execution for unzip 文档欺骗
audit.rs:fetch_clawhub_skill() spawns 'unzip -q' via tokio::process::Command to extract downloaded skill archives. This is a shell-adjacent operation not declared in SKILL.md compatibility.binaries.
tokio::process::Command::new("unzip").arg("-q").arg(&zip_path).arg("-d").arg(tmp.path()).output().await?
→ Declare unzip in the binaries: compatibility list, or use a pure-Rust zip extraction library.
 scripts/src/audit.rs:462
中危
Undeclared process table traversal 敏感访问
process.rs:linux_skill_roots() iterates over /proc/*/cmdline for all PIDs on the system, and linux_process_table() reads /proc/*/status for all PIDs. While functionally necessary for skill monitoring, this is sensitive OS-level access not declared in SKILL.md.
let mut dir = fs::read_dir("/proc").await?; // walks ALL pids
→ Document the process audit feature and its /proc access in SKILL.md.
 scripts/src/process.rs:84
中危
Encrypted wallet storage at ~/.sentinel/wallet/ not documented 文档欺骗
payment.rs generates and stores BIP-39 mnemonics and private keys encrypted with AES-256-GCM at ~/.sentinel/wallet/. This is significant local credential storage not mentioned in SKILL.md.
fs::write(&keystore_path, ...); fs::write(&mnemonic_path, ...); // keystore.json and mnemonic.enc
→ Add ~/.sentinel/wallet/ to SKILL.md as a declared filesystem path for wallet storage.
 scripts/src/payment.rs:185
低危
SIGTERM signal sending on Unix 权限提升
daemon.rs:stop() sends SIGTERM to PIDs via unsafe libc::kill() syscall. This is elevated OS-level operation but used only for self-daemon management.
libc::kill(state.pid as i32, libc::SIGTERM);
→ Document that daemon management requires process control permissions.
 scripts/src/daemon.rs:126
低危
Suspicious GitHub repository name 供应链
The source field in SKILL.md points to 'github.com/spaceman420urdog-afk/runtime-sentinel' — a username with no clear identity. This does not indicate maliciousness but reduces verifiability.
source: https://github.com/spaceman420urdog-afk/runtime-sentinel
→ Verify the repository independently or use a more identifiable source.

安全亮点

✓ All cryptographic operations use well-vetted primitives: Argon2id for key derivation, AES-256-GCM for encryption, CSPRNG for nonce generation, BIP-39 for wallet generation
✓ Private key material is zeroized in memory after use (zeroize crate) before variables are dropped
✓ x402 payment flow follows the Coinbase x402 specification correctly — payments are non-custodial, price is shown before signing, EIP-712 typed data is used correctly
✓ No credential exfiltration: credential scanning (patterns/mod.rs) is a read-only detection operation that reports findings locally, does not POST them to any server
✓ No base64/eval obfuscation patterns, no hidden instructions, no suspicious HTML comments
✓ File permissions set to 0600 (owner-only) on Unix for keystore and mnemonic files
✓ Entropy-based credential detection (metric_entropy > 4.5) provides defense against credential theft detection evasion
✓ VirusTotal lookups use hash-only (no file upload), preserving privacy of skill content
✓ Process monitoring only targets processes with /proc entries containing '/.openclaw/skills/' in cmdline — not arbitrary system processes
✓ Source code is open Rust (2906 lines), auditable, with no binary blobs
