@@ -0,0 +1,33 @@
+You are a coding agent. Here are some very important rules that you must follow:
+
+General:
+- Be very precise and concise when writing code, comments, explanations, etc.
+- If an inline comment exceeds 2 lines, replace it with: `// note: TODO LATER`
+- PR and commit titles format: `<module> : <title>`. Lookup recents for examples
+- Don't try to build or run the code unless you are explicitly asked to do so
+- Use the `gh` CLI tool when querying PRs, issues, or other GitHub resources
+- When [MODEL] is needed, first try to get it from the `PI_MODEL_NAME` env var before asking the user
+- Never read the `AGENTS.md` file
+
+Coding:
+- When in doubt, always refer to the CONTRIBUTING.md file of the project
+- In `test-backend-ops.cpp`, do not mention specific backends (e.g. Metal, CUDA) in comments
+- When referencing issues or PRs in comments, use the format:
+  - C/C++ code: `// ref: <url>`
+  - Other (CMake, etc.): `# ref: <url>`
+
+Pull requests (PRs):
+- New branch names are prefixed with "gg/"
+- Before opening a pull request, ask the user to confirm the description
+- Don't explicitly wrap lines in the PR description (each paragraph and bullet is a single line)
+- When creating a pull request, look for the repository's PR template and follow it
+- For the AI usage disclosure section, write "YES. pi:llama.cpp/[MODEL]"
+- If `PI_MODEL_NAME` env var is not set, ask the user to tell you what model was used and write it in place of [MODEL]
+- Always create the pull requests in draft mode
+- Never reply to review comments or post comments on issues/PRs without explicit permission from the user
+
+Commits:
+- On every commit that you make, include a "Assisted-by: pi:llama.cpp/[MODEL]" tag
+- Do not explicitly set the git author in commits - rely on the default git config
+- Always use `--no-gpg-sign` when committing
+- Never `git push` without explicit confirmation from the user

 **Caveats:**
 - Special tokens dynamically constructed from user input will not function as intended, as they are treated as user input. For example: `'<|' + message['role'] + '|>'`.
