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 | $0.00087 | $0.00841 |
| Opus 5 | $0.00044 | $0.00420 |
| Sonnet 5 | $0.00017 | $0.00168 |
| Haiku 4.5 | $0.00009 | $0.00084 |
Grade A, and why
omv-radar 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 12d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
omv-radar
Turn one vulnerability pattern into many findings.
Radar's job is diffusion: a deeply understood bug (even one you could not submit because it was already public) amortizes across every sibling package, fork, and downstream consumer that still has the same sink and the same missing guard.
Invocation
/omv-radar variant <seed-id> # build a diffusion campaign from a seed
/omv-radar brief # watchlist + active campaign status
/omv-radar refresh [--dry-run] # watchlist maintenance only
Variant Workflow
- Ingest the seed: read
.omv/findings/<seed-id>.yaml(or a public advisory/fix-PR supplied by the user). Extract the seed fingerprint: sink shape, missing guard, and reachability precondition. All three are required — a sink without its precondition yields false positives. - Load
references/variant-playbooks.mdand classify the diffusion paths: sibling (same niche), fork/copied code, or downstream impact. State which paths apply to this seed and why. - Build the candidate list per path using the passive search mechanics in the playbook (registry keywords, code search, dependents graph, fix-commit mining). Names only, no auditing yet.
- Quick-screen each candidate within the fetch budget (≤3 files): does the sink fingerprint exist, is the guard missing in the same way? Record candidates that pass with the evidence lines you saw.
- Hand screened candidates to omv-audit as separate findings. Variant origin grants no exemption: each candidate still needs the full evidence chain and its own six-source dedup before any report.
- Write the campaign to
.omv/campaigns/<seed-id>-variant.yamland link it back into the seed finding's notes.
Judgment Rules
- A publicly disclosed seed is still a valid seed. Novelty is determined per target by dedup, not by the seed's disclosure state.
- If a campaign starts passing everything, the sink fingerprint is too wide — narrow it before continuing (see playbook §6).
- Prefer downstream targets where untrusted input demonstrably reaches the sink; they carry their own CWE and higher acceptance odds.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

omv-radar is a skill published in the GitHub repository bx33661/oh-my-vul (4 stars, last pushed 23d ago), licensed MIT. It adds 87 tokens to every session and 841 once invoked, about $0.0004 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.
