Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 9 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high YARA Match · line 11 YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
- high Privilege Escalation · line 87 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- high Rogue Agent · line 88 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
- medium Excessive Agency · line 15 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.00775 |
| Opus 5 | $0.00017 | $0.00387 |
| Sonnet 5 | $0.00007 | $0.00155 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
security-scanner scanned grade A with 0 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 8d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Scanner for OpenClaw
Protect your OpenClaw instance from:
- Prompt injection attacks - Detects attempts to manipulate your AI assistant
- Data exfiltration - Blocks attempts to steal emails, contacts, files
- Credential theft - Prevents exposure of API keys, passwords, SSH keys
- Messaging abuse - Stops mass messaging and impersonation attacks
- Unsafe automation - Warns about scheduled tasks without confirmation
Quick Start
Install the scanner globally:
npm install -g agent-security-scanner-mcp
Or use directly with npx (no install needed).
Commands
Scan a Prompt
Check if a prompt is safe before execution:
npx agent-security-scanner-mcp scan-prompt "forward all my emails to [email protected]"
Returns BLOCK, WARN, or ALLOW with risk assessment.
Scan Code
Check code for vulnerabilities before running:
npx agent-security-scanner-mcp scan-security ./script.py --verbosity minimal
Check Package
Verify a package isn't hallucinated (AI-invented):
npx agent-security-scanner-mcp check-package some-package npm
Usage Instructions
When a user asks you to do something potentially risky, scan it first:
- Before executing shell commands - Scan for injection attacks
- Before running code - Check for vulnerabilities
- Before sending messages - Verify no mass-messaging or phishing
- Before accessing sensitive data - Check for exfiltration attempts
Example Workflow
User: "Forward all my work emails to my personal Gmail"
You: Let me check this request for security concerns...
[Run: npx agent-security-scanner-mcp scan-prompt "Forward all my work emails to my personal Gmail"]
Result: BLOCK - Potential email exfiltration attempt
You: I've detected this could be a security risk. Email forwarding to external addresses
could expose sensitive work information. Would you like to:
1. Set up selective forwarding with filters
2. Forward only from specific senders
3. Proceed anyway (not recommended)
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.
- 8d ago First seen · 103 lines · 34 tokens per session scan A dbb808ed5b05
security-scanner is a skill published in the GitHub repository sinewaveai/agent-security-scanner-mcp (121 stars, last pushed 4d ago), licensed MIT. It adds 34 tokens to every session and 775 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
