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 5.1 | $0.00064 | $0.01147 |
| Opus 5 | $0.00032 | $0.00574 |
| Sonnet 5 | $0.00013 | $0.00229 |
| Haiku 4.5 | $0.00006 | $0.00115 |
Grade A, and why
security-scan 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vibecheck Security Scan
Run 156 automated security checks against the current codebase. Produces a categorized report with severity levels and fix suggestions.
How to Run
- Detect the project's tech stack from package.json, requirements.txt, or file extensions
- Glob for all source files:
**/*.{js,jsx,ts,tsx,py,sql,json,yaml,yml,html,vue,svelte,go,rb,php,sh,tf} - Read each file and apply the check patterns from the reference documents
- Produce a markdown report

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.

security-scan is a skill published in the GitHub repository Wishmakingfairy/vibecheck (4 stars, last pushed 5mo ago), licensed MIT. It adds 64 tokens to every session and 1,147 once invoked, about $0.0003 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 2026-08-31.
