bus-drivers-i2c-spi SKILL.md skillA
bus-drivers-i2c-spi from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/bus-drivers-i2c-spi@git:20260905.fd53e99Pins git:20260905.fd53e99 in mdr.lock. Pin the fingerprint instead.

Use when writing a Linux i2c_driver or spi_driver, doing bus register access, DMA-safe SPI transfers, or debugging -EREMOTEIO. Not for MMIO platform drivers: use platform-device-model.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bus drivers (I2C and SPI) ## Contract | Field | Bound contract | |---|---| | Trigger | Writing a Linux I2C or SPI client driver: bus registration, `i2c_transfer` or `spi_sync`, regmap over the bus, DMA-safe SPI buffers, device tree binding on bus children, or NACK and `-EREMOTEIO` debugging. | | Authority | Read-only. Writes nothing. Chat output only. No remote mutation. | | Side effect | Returns driver skeletons and debug commands. No source files are modified. | | Done | The client driver skeleton, the transfer or regmap access pattern, the DT child node, and a debug path for the reported symptom are delivered. | ## Inputs 1. Device and bus (required): the chip address on I2C or chip-select on SPI, the adapter or controller, and the datasheet register map. 2. Transfer shape (optional): register width and value width, which set `regmap_config`. 3. Failure report (optional): the symptom, such as `-EREMOTEIO`, a stuck bus, or a probe that never runs. ## Procedure 1. Write the I2C client driver skeleton. The bus core owns the adapter; the driver owns registers only. ```c #include <linux/i2c.h> #include <linux/mod_devicetable.h> …

How to install
mdr add outlinedriven/outline-driven-development/bus-drivers-i2c-spi@sha256:4245ad9f2abe3faaThe line at the top of this page pins the label git:20260905.fd53e99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
