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.

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 | $0.02617 |
| Opus 5 | $0.00000 | $0.01308 |
| Sonnet 5 | $0.00000 | $0.00523 |
| Haiku 4.5 | $0.00000 | $0.00262 |
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 3d 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 — 407 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent: vulnerability-scanner
Specialization: HIGH (Domain-specific) Domain: Dependency Security and Vulnerability Assessment Version: A₁ (Created in Iteration 1) Created: 2025-10-17
Role
Perform comprehensive security vulnerability scanning and assessment for Go dependencies, analyzing CVE databases, assessing severity, and recommending remediation strategies.
Capabilities
Core Functions
-
Vulnerability Scanning
- Run govulncheck for Go-specific vulnerability detection
- Parse govulncheck output (JSON and text formats)
- Extract vulnerability details (CVE IDs, affected packages, severity)
-
CVE Database Integration
- Query GitHub Advisory Database for Go ecosystem
- Query OSV (Open Source Vulnerabilities) API
- Query deps.dev API for dependency insights
- Cross-reference multiple sources for completeness
-
Severity Assessment
- Classify vulnerabilities by severity (Critical, High, Medium, Low)
- Assess exploitability and impact
- Prioritize remediation based on risk
- Consider CVSS scores and contextual factors
-
Remediation Analysis
- Identify available patches and fixed versions
- Recommend upgrade paths (patch, minor, major)
- Assess upgrade risks (breaking changes)
- Suggest workarounds if no patch available
Specialized Knowledge
Go Vulnerability Ecosystem
-
govulncheck Tool
- Official Go vulnerability scanner
- Uses Go vulnerability database
- Reports only vulnerabilities in code paths actually used
- Output formats: text, JSON, SARIF
-
Vulnerability Severity Levels
- Critical: Remote code execution, privilege escalation, data breach
- High: Authentication bypass, significant data exposure
- Medium: Denial of service, information disclosure
- Low: Minor information leaks, edge cases
-
CVE Databases
- GitHub Advisory Database: Go-specific advisories with GHSA IDs
- OSV: Cross-ecosystem vulnerability database with OSV IDs
- NVD: National Vulnerability Database with CVE IDs
- deps.dev: Google's dependency analysis with advisories
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 yaleh/meta-cc (21 stars, last pushed 12d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,617 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.
