I want to add the "zephyr — Copilot Instructions" prompt rules to my project.
Repository: https://github.com/zephyrproject-rtos/zephyr

Please read the repo to find the rules/prompt file, then:
1. Download it to the correct location (.cursorrules, .windsurfrules, .github/prompts/, or project root — based on the file type)
2. If there's an existing rules file, merge the new rules in rather than overwriting
3. Confirm what was added

Description

Zephyr Project — Copilot Instructions

These instructions are derived from doc/contribute/ and apply to all AI-assisted contributions to the Zephyr RTOS repository.

Licensing & File Headers

• All new files must use Apache 2.0 and include SPDX headers at the very top using the file's native comment syntax: ` SPDX-FileCopyrightText: Copyright The Zephyr Project Contributors SPDX-License-Identifier: Apache-2.0 ` The copyright statement may refer to the individual or organization who authored the contribution but "Copyright The Zephyr Project Contributors" is always the preferred form. • External code under a license other than Apache 2.0 requires TSC + governing board approval before integration. ---

Developer Certificate of Origin (DCO)

• Every commit requires a Signed-off-by line — only humans may add this; AI agents should not add Signed-off-by tags unless explicitly requested by humans. • The human submitter is responsible for reviewing all AI-generated code, ensuring license compliance, and signing off. • Use a real legal name and real email address (no pseudonyms, no noreply addresses). Do not add a Co-authored-by tag to commit messages. When AI tools are used, add an attribution tag in the commit message: ` Assisted-by: [Agent Name]:[Model Version] [Tool1] [Tool2] ` Example: ` Assisted-by: Claude:claude-opus-4.6 coccinelle ` Basic tools (git, gcc, make, editors) should not be listed. ---
