+# Project Context — Python (General)
+
+This repository is a general Python project. Ensure a virtual environment exists, create it with `uv` if missing, keep `requirements.txt` accurate, and then follow the user's instructions.
+
+---
+
+## Environment
+
+- Virtual env: prefer `uv` to manage the venv and installs.
+  - Create: `uv venv` (optionally `--python <version>`).
+  - Use: activate `.venv` or run commands via `uv run <cmd>`.
+- Dependencies:
+  - If `requirements.txt` exists: `uv pip install -r requirements.txt`.
+  - When packages are added/removed, update `requirements.txt` to stay accurate.
+    - Default policy: freeze exact versions unless the user specifies otherwise (e.g., `uv pip freeze > requirements.txt`).
+- Never assume the environment is active.
+  - Before asking the user to run a command manually, verify whether the virtual environment is active.
+  - If not active, instruct explicitly how to activate it:
+    - Unix/macOS: `source .venv/bin/activate`
+  - Prefer `uv run <command>` to avoid activation issues.
+
+---
+
+## Directory & File Safety Rules
+
+When writing files or creating directories:
+
+- If instructed to create or write into a folder with a specific name:
+  - **First verify whether a directory with that name already exists.**
+  - Do NOT create it blindly.
+  - If it exists, reuse it unless the user explicitly requests overwriting.
+  - If a file would be overwritten, clarify intent unless overwrite is explicitly requested.
+
+- Avoid duplicating folder structures.
+- Do not create parallel directories with similar names (e.g., `src` and `src_new`) unless explicitly requested.
+- Maintain consistent project structure conventions.
+- Respect existing naming conventions.
+
+---
+
+## Command Execution Policy
+
+When suggesting commands to the user:
+
+1. Ensure the command is compatible with the project’s tooling (`uv` preferred).
+2. Avoid global installs.
+3. Avoid OS-specific assumptions unless specified.
+4. If the command modifies the environment (e.g., installing packages):
+   - Make sure `requirements.txt` is updated accordingly.
+5. If the user is inside a container or remote environment, do not assume local execution context.
+6. Never assume shell state (activated venv, exported variables, current directory). Always be explicit.
+
+---
+
+## Operating Model
+
+- Ask quick clarifying questions if versions, entry points, or expected behaviors are ambiguous.
+- Prefer small, incremental changes with brief plans for multi-step work.
+- Do not commit secrets.
+- Avoid committing large build artifacts unless requested.
+- Do not introduce new tooling (linters, formatters, frameworks) unless:
+  - The user requests it.
+  - It is strictly necessary to complete the task.
+- Avoid unnecessary architectural refactors.
+- Prioritize minimal, reversible changes.
+
+---
+
+## Code Modification Principles
+
+- Follow existing code style and architecture.
+- Avoid unnecessary refactors.
+- Keep changes minimal and scoped.
+- Preserve backward compatibility unless explicitly told otherwise.
+- If introducing new files:
+  - Place them in logically consistent locations.
+  - Avoid breaking import paths.
+- Do not remove or rename files unless explicitly instructed.
+
+---
+
+## Reproducibility
+
+- The environment must remain reproducible from scratch using:
+  - `uv venv`
+  - `uv pip install -r requirements.txt`
+- No hidden dependencies.
+- No reliance on undeclared system packages unless clearly documented.
+- Ensure all runtime dependencies are declared.
+
+---
+
+## Typical Tasks
+
+Agents operating in this repository may:
+
+- Implement features.
+- Fix bugs.
+- Run tests.
+- Update documentation.
+- Improve structure when explicitly requested.
+- Keep the environment reproducible and synced with declared requirements.
+
+---
+
+## Safety & Determinism Rules
+
+- Do not perform destructive actions (e.g., delete directories, drop databases) unless explicitly instructed.
+- Do not overwrite configuration files without confirmation.
+- Always prefer deterministic operations.
+- If uncertain about intent, ask before acting.
