Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00039 | $0.19308 |
| Opus 5 | $0.00019 | $0.09654 |
| Sonnet 5 | $0.00008 | $0.03862 |
| Haiku 4.5 | $0.00004 | $0.01931 |
Grade B, and why
vuln-scanner scanned grade B with 2 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 yesterday.
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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
network is open, but `pip install` / `curl | sh` / `tar` are **not** on the in-run Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

100% identical to vuln-scanner — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 1,135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
${var} — Action selector, shaped
[<action>][:<owner/repo>]. Empty or a bareowner/repo→ scan arm (audit that repo, or auto-select a trending one).resubmit/resubmit:owner/repo→ re-submit arm (probe the security watchlist for repos that just enabled PVR and submit any queued advisory).disclose/
- `` → scan, auto-select from trending
openai/whisper→ scanopenai/whisperresubmit→ probe the whole watchlist and re-submit what flippedresubmit:vercel/next.js→ probe just that repo (one-off)disclose(aliaspoc-smoke→ exercise the PoC gate against a benign real Base fork (no audit or disclosure)
Today is ${today}. Read memory/MEMORY.md and the last 30 days of memory/logs/ before starting.
Why this skill exists
This is the write / action arm of the vuln-disclosure loop — one skill covering the full responsible-disclosure lifecycle:
- Scan — a security scanner that dumps unpatched vulnerabilities into public PRs is a zero-day publisher, not a helper. This skill matches industry practice: Private Vulnerability Reporting (PVR) for code flaws, public PRs only for dependency CVEs that are already public. Bad disclosure burns credibility and puts users at risk.
- Re-submit — when a scan finds a HIGH/CRITICAL issue in a repo with no PVR, no
SECURITY.md, and no reachable contact, it has no safe channel — so it logs the finding as"channel": "skipped"inmemory/vuln-scanned.jsonand stages a watchlist row. Without a weekly probe those findings silently age until the responsible-disclosure window closes. The re-submit arm closes that loop. - Disclose — when the only responsible path is a private email to the maintainer, drafts sit in
memory/pending-disclosures/withstatus: pending-operator-send, waiting for a human. The disclose arm finds drafts explicitly armed for auto-send, composes the email, and sends it in-run (Resend via./secretcurl) behind a set of fail-closed caps — the send is the arm's final action.
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.

vuln-scanner is a skill published in the GitHub repository aaronjmars/aeon-agent (11 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 19,308 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (downloads and executes remote code, makes network calls). It is 100% identical to vuln-scanner, differing in 0 lines, and is treated as a copy.
