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.

What it costs to keep this loaded
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 | $0.00126 | $0.01498 |
| Opus 5 | $0.00063 | $0.00749 |
| Sonnet 5 | $0.00025 | $0.00300 |
| Haiku 4.5 | $0.00013 | $0.00150 |
Grade A, and why
offensive-zigbee-thread-matter 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 5d 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 — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zigbee / Thread / Matter Attacks
802.15.4-based mesh protocols underpin most "smart home" devices. Zigbee is widely deployed and has well-known crypto-key-reuse issues; Thread (modern, IPv6-based) ships with stronger defaults; Matter unifies their commissioning model with stronger crypto but still has implementation pitfalls.
Quick Workflow
- Sniff target frequency (channels 11–26 in 2.4 GHz)
- Identify network coordinator and joining devices
- For Zigbee: try Touchlink commissioning with the well-known key
- Capture join-key exchange when devices commission
- Replay or inject ZCL/ZHA cluster commands
Hardware
| Adapter | Use |
|---|---|
| TI CC2531 USB stick | Cheap, works with Zigbee2MQTT, KillerBee |
| TI CC2540 / CC2652 | Zigbee + Thread + BLE |
| Sonoff Zigbee Dongle E (CC2652P) | Modern, well-supported |
| ApiMote (KillerBee dev) | Multi-channel, scapy-dot15d4 |
| HackRF + appropriate firmware | Lower-level RF flexibility |
Discovery + Sniffing
# KillerBee suite
zbstumbler -i 0 # find Zigbee networks
zbid # ID coordinators
zbdump -c 11 -w zigbee.pcap # dump channel 11 to pcap
# scapy-dot15d4 for crafted frames
python3
>>> from scapy.contrib.dot15d4 import *
>>> sniff(iface='/dev/ttyACM0', count=50)
In Wireshark with the dot15d4 + zbee_nwk dissectors, you'll see frame counters, network keys (if joined), and ZCL commands.
Touchlink Commissioning Abuse
Touchlink (used by Zigbee 3.0 commissioning, especially in lighting) uses a well-known transport key:
0x9F559A553B7A6B2C5C4FBB4E84956F3D
Many consumer Zigbee bulbs / strips accept Touchlink commissioning from any nearby radio with this key — joining them to your network or stealing them from theirs.
# z3sec — Zigbee 3 commissioning attack toolkit
git clone https://github.com/IoTsec/Z3sec
python z3sec_inter_pan.py --command "factory_reset_request" --device <addr>
python z3sec_inter_pan.py --command "join_network" --network <PANID>
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-zigbee-thread-matter is a skill published in the GitHub repository SnailSploit/Claude-Red (3,048 stars, last pushed 9d ago), licensed MIT. It adds 126 tokens to every session and 1,498 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.
