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 | $0.00123 | $0.01756 |
| Opus 5.5 | $0.00049 | $0.00702 |
| Sonnet 5.5 | $0.00025 | $0.00351 |
| Haiku 4.5 | $0.00012 | $0.00176 |
Grade B, and why
offensive-bluetooth-classic scanned grade B with 1 finding 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 1mo 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 hciconfig hci0 up How it starts
The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bluetooth Classic (BR/EDR) Attacks
Older than BLE, less commonly attacked today, but still present in cars, industrial sensors, audio gear, and legacy enterprise hardware. Many of the well-known historic attacks (BlueSnarf, BlueBug) are mitigated; KNOB and the BlueBorne family remain relevant against unpatched devices.
Quick Workflow
- Discover devices with
hcitool/bluetoothctl/redfang - Enumerate exposed services via SDP
- Test each service profile for unauth access
- Check pairing crypto (KNOB applicability)
- Proximity-physical attacks for legacy / unpatched
Discovery
# Modern adapter (built-in or USB Bluetooth 4.0+)
sudo hciconfig hci0 up
sudo hcitool inq # inquiry
sudo hcitool scan --length=12 # 12-second scan
# bluetoothctl interactive
bluetoothctl
> scan on
> devices
# Discoverable-mode-only devices appear; non-discoverable need address brute
sudo redfang -r 00:00:00:00:00:00-FF:FF:FF:FF:FF:FF
# (very slow — ~7 hours per OUI prefix)
Service Discovery (SDP)
# List all services on a device
sdptool browse AA:BB:CC:DD:EE:FF
sdptool records AA:BB:CC:DD:EE:FF
Common profiles and their attack relevance:
| Profile | UUID | Attack |
|---|---|---|
| OBEX Object Push (OPP) | 0x1105 | BlueSnarf/BlueBug on legacy phones (mostly extinct) |
| OBEX File Transfer (FTP) | 0x1106 | Browse / write filesystem on legacy devices |
| Headset (HSP/HFP) | 0x1108 / 0x111E | Eavesdrop active call audio |
| Serial Port Profile (SPP) | 0x1101 | Industrial/IoT debug ports — often unauthenticated |
| HID | 0x1124 | Keyboard/mouse impersonation |
| Audio Sink/Source (A2DP) | 0x110B / 0x110A | Audio injection/eavesdrop |
SPP Abuse
The Serial Port Profile (SPP) tunnels arbitrary data over Bluetooth as a virtual COM port. Industrial / IoT devices use it for debug or telemetry, often without authentication.
# Connect to SPP service, channel typically 1
sudo rfcomm bind /dev/rfcomm0 AA:BB:CC:DD:EE:FF 1
sudo screen /dev/rfcomm0 9600
# Then interact with the device's CLI / debug menu
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-bluetooth-classic is a skill published in the GitHub repository Miosa-osa/OSA (78 stars, last pushed 11d ago), licensed Apache-2.0. It adds 123 tokens to every session and 1,756 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-14.
