Use when starting a server or any long-running / heavy task. Use processes + devenv up; don't block the shell; poll logs instead of piping out of view.

Don't block the shell on a server or a heavy build, and don't pipe output to a file you then can't see.
processes entry and run devenv up (optionally
devenv up <name>). It supervises them; it does not tie up your shell.scripts/tasks entry blocks until it exits; that's correct for short work, wrong for a
server.Grep-able surface comparison: scripts-tasks-processes.md. Worked example (processes, devenv up,
polling, not blocking): the background-and-long-running-work.md article.
For when in the lifecycle to start processes, see the repoman skill.
Use when writing a scripts/tasks/processes entry or a manager module. Covers which surface to use, guarding enterShell echoes, and the 0/1/2/3 exit contract.
Use when editing devenv.yaml or adding an input/import. Covers flake:false for modules, nixpkgs-python for version pins, and transitive inputs.
Use when you edited a modules/ file, devenv.nix, or env.* and nothing changed. Resolves the lock + eval-cache staleness loop.
Use on ModuleNotFoundError or import failures inside the devenv shell, or after a fresh venv. The venv exists but deps may not be installed.
Use when about to run pytest, python, uv, ruff, or any build/tooling command in this repo. Enforces running through the devenv shell.
Use on "command not found", the shell won't enter, or eval errors. A symptom→cause→fix decision tree for devenv repos.
