claude-red is a library of structured skills that give Claude specialized offensive-security methods for areas such as web vulnerabilities, shellcode, exploit development, and identity systems. It is intended for authorized red-team work, bug-bounty triage, security research, CTF preparation, and operator training. Its catalogue contains the project's skills for loading these security specializations into Claude.
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 | $0.00113 | $0.01401 |
| Opus 5 | $0.00056 | $0.00700 |
| Sonnet 5 | $0.00023 | $0.00280 |
| Haiku 4.5 | $0.00011 | $0.00140 |
Grade A, and why
offensive-z-wave 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 2d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Z-Wave Attacks
Z-Wave runs in the 800/900 MHz ISM band (US: 908 MHz, EU: 868 MHz). Older networks used the S0 security scheme with a fixed-derivation network key — long-known to be flawed. S2 (mandatory for Z-Wave Plus v2 since 2017) uses ECDH commissioning and is significantly stronger.
Quick Workflow
- Identify region (US 908 MHz / EU 868 MHz) — adapter frequency must match
- Sniff inclusion (commissioning) traffic — that's where keys are exchanged
- Determine S0 vs S2 from frame format
- For S0: derive/replay; for S2: analyze ECDH and look for implementation flaws
Hardware
| Adapter | Use |
|---|---|
| Z-Force (legacy, hard to find) | Original research tool |
| EZ-Wave (custom HackRF firmware) | Modern, full transceiver |
| Aeotec Z-Stick | Commercial controller, useful as legitimate node |
| HackRF + open Z-Wave firmware | Multi-band SDR approach |
| RTL-SDR + ZniffMobile (passive only) | Cheap sniffer |
Sniffing
# EZ-Wave (HackRF firmware-based)
git clone https://github.com/cureHsu/EZ-Wave
ezwave-sniff -f 908.4MHz -o capture.pcap
# Wireshark with the Z-Wave dissector parses captured frames
wireshark capture.pcap
Look for the inclusion phase (controller adding new device) — that's where the network key is exchanged.
S0 Security Flaw
S0 derives the network key from a fixed all-zero PSK during the inclusion of the first device. That fixed material is well-known — any S0 network you sniff during inclusion can be decrypted offline.
S0 commissioning:
1. New node joins → controller sends key with zero-PSK encryption
2. Attacker sniffs commissioning frame → derives session key
3. All future S0 traffic on that network is decryptable
If you can:
- Trigger inclusion (factory-reset a node, or wait for legitimate inclusion)
- Sniff during the ~2-second key-exchange window
You own the network key for that mesh.
S2 (Z-Wave Plus / S2 Authenticated)
S2 fixes S0 by using ECDH for commissioning:
- Each device has a Curve25519 keypair
- Inclusion uses DSK (Device Specific Key) verified out-of-band (sticker/QR)
- Network key never traverses the air in plaintext
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.

offensive-z-wave is a skill published in the GitHub repository SnailSploit/Claude-Red (3,026 stars, last pushed 6d ago), licensed MIT. It adds 113 tokens to every session and 1,401 once invoked, about $0.0006 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 2026-09-03.
