WalkthroughA new documentation file was added to provide AI assistants with detailed project context. The Nixpacks configuration was updated to simplify Python installation, remove redundant overrides, clarify build steps, and allow default virtual environment management. No changes were made to code declarations or public entities. Changes

4-9: Move thepip install --upgrade pipinto the same layer to avoid cache bust-through.Upgrading
pipinvalidates the derivation layer that caches Python packages; subsequent image rebuilds will re-download all wheels. Consider pinning a recentpipinnixPkgsor merging the two installs:-cmds = [ - "pip install --upgrade pip", - "pip install -r requirements.txt" -] +cmds = ["python -m pip install --upgrade pip -r requirements.txt"]That keeps a single layer and uses the interpreter-qualified invocation for clarity.
25-27: Section is now empty – remove it to reduce cognitive load.Since all keys were deleted, the bare
[nixpacks]table adds no value and may confuse readers.-# Let Nixpacks handle virtual environment creation automatically -[nixpacks] +# Nixpacks default venv behaviour retained.github/copilot-instructions.md (1)
64-75: Include virtual-env hint to mirror Nixpacks local workflow.Developers following these steps locally will install packages globally unless they remember to create a venv. Add a note or wrap the commands:
python -m venv .venv && source .venv/bin/activate pip install -r requirements.txtKeeps parity with the containerised build.

python312has only just landed innixpkgsunstable. If your deployment stack is pinned tostableor an older revision, the build will fail because the attribute is missing. Either:-nixPkgs = ["python312", "pip"] +nixPkgs = ["python311", "pip"] # or bump the channel used by Nixpacksor make sure the Nix channel used by the builder contains 3.12.

🛠️ Refactor suggestion
Python version mismatch between docs and build configuration.
Docs say “Python 3.9+” while nixpacks.toml pins 3.12. Align them to avoid on-boarding confusion and runtime surprises (e.g., 3.12 deprecations).
🤖 Prompt for AI Agents
In .github/copilot-instructions.md around lines 17 to 19, the Python version
mentioned in the documentation is "Python 3.9+" but the build configuration in
nixpacks.toml pins Python 3.12. Update the documentation to reflect Python 3.12
to ensure consistency and avoid confusion during onboarding and runtime issues.

🛠️ Refactor suggestion
cp -r backend/* . drops dotfiles and returns a non-zero exit when the folder is absent.
- Dot-files such as
.env.examplewill not be copied because of shell globbing rules. - If
backend/is missing (e.g., a shallow checkout),cpexits with 1, and theechothat follows masks the failure but still pollutes the logs.
A safer, idempotent alternative:
-"cp -r backend/* . || echo 'Backend files already in place'"
+"shopt -s dotglob && cp -R backend/* . 2>/dev/null || echo 'No backend directory to copy'"📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In nixpacks.toml around lines 13 to 15, the command `cp -r backend/* .` fails to
copy dotfiles and returns a non-zero exit code if the backend directory is
missing, causing misleading logs. Replace this with a command that copies all
files including dotfiles safely and checks for the existence of the backend
directory before copying to avoid errors and ensure idempotency.
