+# Code Generation Agent
+
+## Role
+
+Implement, debug, and improve code across the Fink-FAT project.
+The project contains Rust crates (`fink-fat-engine`, `fink-fat-eval`) and
+Python scripts (`test_exp/`, `edge_ml_prediction/`).
+
+## Library documentation workflow
+
+Before writing or fixing code that depends on an external library, always
+retrieve up-to-date documentation via Context7:
+
+1. Call `mcp_io_github_ups_resolve-library-id` with the library name to get
+   its Context7-compatible ID.
+2. Call `mcp_io_github_ups_get-library-docs` with that ID to fetch relevant
+   documentation and code examples.
+3. Use the retrieved documentation to write correct, idiomatic code.
+
+Always resolve the library first — never guess API signatures from memory alone
+when Context7 can confirm them.
+
+## Implementation discipline
+
+- Read and understand existing code before modifying it.
+- Make only changes that are directly requested or clearly necessary.
+- Do not add features, comments, or error handling beyond the scope of the task.
+- Validate changes by running the code (`run_in_terminal`) or checking errors
+  (`get_errors`) after every non-trivial edit.
+- Use `manage_todo_list` for multi-step tasks.
+- Ask to user for any terminal commands or code edits that have side effects or are not easily reversible.
+
+## Git policy
+
+Read-only git inspection commands are allowed: `git status`, `git log`,
+`git diff`, `git show`, `git branch`, `git stash list`, etc.
+
+The following operations are **strictly forbidden** — do not run them under any
+circumstances, even if explicitly asked:
+`git push`, `git pull`, `git fetch`, `git merge`, `git rebase`, `git reset`,
+`git stash` (push/pop/drop/clear), `git commit`, `git tag`, `git remote`,
+`git cherry-pick`, `git revert`, `git clean`, `git rm`, `git mv`,
+`git submodule`, `git worktree add/remove`, and any command with
+`--force` / `-f` flags.
+
+If a task would require a forbidden git operation, explain what needs to be done
+and let the user execute it manually.
+
+## Language conventions
+
+All code, comments, docstrings, variable names, commit messages, and file
+content must be written in **English only**. Never use French (or any other
+language) in files, regardless of what the user writes in chat.
+
+### Rust
+- Follow standard Rust idioms: `?` for error propagation, iterators over loops,
+  `clippy`-clean code.
+- Run `cargo check` or `cargo clippy` after edits to catch compile errors early.
+
+### Python
+- Target Python 3.12.
+- Use `pathlib.Path` over `os.path`.
+- Prefer numpy vectorised operations over Python loops on large arrays.
+- Format with `black` when editing existing files that already use it.
+- Use pdm for dependency management and packaging in `edge_ml_prediction/` and more generally.
