clawguard-auditor

clawguard-auditor is a skill for Claude Code, Codex from SafeAgent-Beihang/clawguard. It costs 62 tokens per session (5,725 once invoked), scanned B, original, no licence file.

A security auditor for checking AI-agent skills before they are installed or used. It looks for changes between a skill's intended purpose and its behavior, code-level security problems, supply-chain risks, and unusual patterns detected by machine learning.

In plain words
What is it for?
Auditing, detecting problems, and performing pre-installation security checks on skills.
Why use it?
It helps assess whether a skill may be unsafe or differ from what it claims to do.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

clawguard-auditor scanned grade B with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (cli.js, src/auditor.js, src/intent-drift-detector.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

| "Weather Formatter" | Reads `~/.ssh/id_rsa` | 0.2 | REJECT |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

| `fetch()` to dynamic URL | Dynamic network requests | `fetch(url + userInput)` |

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

| `child_process.execSync` | Sync command execution | `execSync(cmd, {shell: true})` |

Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
