vetix: Instructions file for Codex

AGENTS.md

vetix AGENTS.md is an instructions file for Codex, OpenCode from HuTa0kj/vetix. It costs 920 tokens per session, scanned A, original, MIT.

A project map for Vetix, an agent-based scanner that checks coding-agent skill folders for obvious and hidden security threats. It explains the repository's files, workflow stages, plugins, prompts, and configuration.

In plain words
What is it for?
Use it to navigate Vetix, understand its command-line entry point and scanning workflow, and locate plugins, prompts, models, middleware, and tests.
Why use it?
It helps an agent find the right part of the codebase before changing or debugging the scanner. It also clarifies how rule-based checks and language-model analysis fit together.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is HuTa0kj/vetix's own configuration. It tells Codex and OpenCode how to work on vetix itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vetix configures →

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 A, and why

vetix AGENTS.md 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 6d 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.

Vetix — Project Map

Vetix is an LLM-agent-based scanner for SKILL directories. It pairs deterministic plugin rules with an LLM behavioral analyst so both obvious IOCs and subtle, obfuscated attack chains get caught in one pass.

End-user docs live in README.md / README_CN.md. This file is a map for navigating the codebase.

Workflow

gather_base_info → plugins_check → plugins_findings_verify → behavioral_analysis → report

State is shared via SkillSafeAuditState (Pydantic). Each node returns a dict that merges into state; there are no conditional edges.

Scans short-circuit on a cache hit: before the workflow is built, agent.py compares directory_hash[:16] (computed by gather_base_info) against the subdirectories of the output directory and, if <output-dir>/<hash[:16]>/report.json exists, loads it back into state and renders it instead of running the pipeline. --force bypasses the cache.

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.
