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 | $0.00029 | $0.00679 |
| Opus 5 | $0.00015 | $0.00340 |
| Sonnet 5 | $0.00006 | $0.00136 |
| Haiku 4.5 | $0.00003 | $0.00068 |
Grade B, and why
hardware 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 4d 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.

88% identical to hardware — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hardware (I2C / SPI)
Use the i2c and spi tools to interact with sensors, displays, and other peripherals connected to the board.
Quick Start
# 1. Find available buses
i2c detect
# 2. Scan for connected devices
i2c scan (bus: "1")
# 3. Read from a sensor (e.g. AHT20 temperature/humidity)
i2c read (bus: "1", address: 0x38, register: 0xAC, length: 6)
# 4. SPI devices
spi list
spi read (device: "2.0", length: 4)
Before You Start — Pinmux Setup
Most I2C/SPI pins are shared with WiFi on supported boards. You must configure pinmux before use.
See references/board-pinout.md for board-specific commands.
Common steps:
- Stop WiFi if using shared pins:
/etc/init.d/S30wifi stop - Load i2c-dev module:
modprobe i2c-dev - Configure pinmux with
devmem(board-specific) - Verify with
i2c detectandi2c scan
Safety
- Write operations require
confirm: true— always confirm with the user first - I2C addresses are validated to 7-bit range (0x03-0x77)
- SPI modes are validated (0-3 only)
- Maximum per-transaction: 256 bytes (I2C), 4096 bytes (SPI)
Common Devices
See references/common-devices.md for register maps and usage of popular sensors:
AHT20, BME280, SSD1306 OLED, MPU6050 IMU, DS3231 RTC, INA219 power monitor, PCA9685 PWM, and more.
Troubleshooting
| Problem | Solution |
|---|---|
| No I2C buses found | modprobe i2c-dev and check device tree |
| Permission denied | Run as root or add user to i2c group |
| No devices on scan | Check wiring, pull-up resistors (4.7k typical), and pinmux |
| Bus number changed | I2C adapter numbers can shift between boots; use i2c detect to find current assignment |
| WiFi stopped working | I2C-1/SPI-2 share pins with WiFi SDIO; can't use both simultaneously |
devmem not found |
Download separately or use busybox devmem |
| SPI transfer returns all zeros | Check MISO wiring and device power |
| SPI transfer returns all 0xFF | Device not responding; check CS pin and clock polarity (mode) |
What ships with it
2 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.
- 4d ago First seen · 65 lines · 29 tokens per session scan B a3b7f8c29797
hardware is a skill published in the GitHub repository AbdullahMalik17/malikclaw (15 stars, last pushed 9d ago), licensed MIT. It adds 29 tokens to every session and 679 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). It is 88% identical to hardware, differing in 8 lines, and is treated as a copy.
