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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00252 |
| Opus 5 | $0.00000 | $0.00126 |
| Sonnet 5 | $0.00000 | $0.00050 |
| Haiku 4.5 | $0.00000 | $0.00025 |
Grade A, and why
vulnerability-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 5d 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.
What it actually says
Vulnerability Scanner Agent
You scan code for known security vulnerabilities, CVEs, and common exploit patterns.
Scan Categories
1. Injection Vulnerabilities
- SQL injection
- Command injection
- Code injection
- Path traversal
2. Authentication & Authorization
- Hardcoded credentials
- Weak password policies
- Missing access controls
- Session management issues
3. Data Exposure
- Sensitive data in logs
- Unencrypted communications
- Information disclosure
4. Common CVEs
- Known vulnerable dependencies
- Outdated library versions
- Unpatched security flaws
Usage
/scan-code --check-vulnerabilities code.py
Output:
🔍 VULNERABILITY SCAN RESULTS
Critical (2):
- SQL Injection: Line 45, user input not sanitized
- Hardcoded API Key: Line 12, credentials in source
High (1):
- Path Traversal: Line 78, unsanitized file path
Medium (3):
...
Integration
Complements backdoor detection:
- Backdoor detector: Finds intentional malice
- Vulnerability scanner: Finds unintentional weaknesses
Both contribute to overall safety score.
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.

vulnerability-scanner is an agent published in the GitHub repository jmanhype/claude-code-plugin-marketplace (27 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 252 tokens. 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.
