List the contents of a directory in the nRF Connect SDK repo (nrfconnect/sdk-nrf @ main).

Useful starting paths:

• "doc/nrf" → Documentation root (RST files)

• "doc/nrf/protocols" → Bluetooth, LTE, Thread, Zigbee docs

• "doc/nrf/libraries" → Library reference docs

• "doc/nrf/applications" → Application-level docs

• "samples" → All sample projects

• "samples/bluetooth" → Bluetooth LE samples

• "samples/cellular" → LTE/cellular modem samples

• "samples/matter" → Matter protocol samples

• "samples/nfc" → NFC samples

• "samples/tfm" → Trusted Firmware-M samples

• "samples/crypto" → Cryptography samples

Returns dirs first, then files, with full paths you can pass to nrf_read.

Read the contents of a file from the nRF Connect SDK repo (nrfconnect/sdk-nrf @ main).

Works for any text file: .rst documentation, .c/.h source, CMakeLists.txt, Kconfig, prj.conf, .yaml, README.rst, etc.

Use nrf_list to discover paths first. Examples:

• "samples/bluetooth/central_bas/README.rst"

• "samples/bluetooth/central_bas/src/main.c"

• "samples/bluetooth/central_bas/CMakeLists.txt"

• "samples/bluetooth/central_bas/prj.conf"

Search for code or documentation across the nRF Connect SDK repo using GitHub code search.

Supports GitHub search qualifiers to narrow results:

• Plain keyword: "DFU_TARGET_IMAGE_TYPE_ANY"

• Docs only: "FOTA path:doc/nrf"

• Samples only: "peripheral_hr path:samples"

• Specific extension: "CONFIG_BT_PERIPHERAL extension:conf"

• Source files only: "bt_le_adv_start extension:c"

• Headers only: "struct bt_conn extension:h"

Returns matching file paths (up to 20). Use nrf_read to fetch the content. Note: Requires GITHUB_TOKEN for reliable results (unauthenticated search is heavily rate-limited).
