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 | $0.00215 | $0.04816 |
| Opus 5 | $0.00108 | $0.02408 |
| Sonnet 5 | $0.00043 | $0.00963 |
| Haiku 4.5 | $0.00021 | $0.00482 |
Grade B, and why
blacklist-ip 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt install -y whois dnsutils curl jq --break-system-packages 2>/dev/null || \ Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
sudo apt install -y whois dnsutils curl jq --break-system-packages 2>/dev/null || \ The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

blacklist-ip is a skill published in the GitHub repository hackingyseguridad/IA (2 stars, last pushed yesterday), with no licence file. It adds 215 tokens to every session and 4,816 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
