Three rules cover most input mistakes:
A devenv-module input needs flake: false. Without it, devenv tries to evaluate the input
as a flake and the import fails.
inputs:
repoman:
url: path:../repoman/modules
flake: false
Pinning languages.python.version needs the nixpkgs-python input. A bare version string
with no such input silently won't resolve.
Remote module imports merge devenv.nix, not devenv.yaml. A module you import does not
bring its own inputs along — you must declare its transitive inputs in your devenv.yaml.
After any devenv.yaml change, re-lock: rm -f devenv.lock (or devenv update <input>) — see the
devenv-module-edits skill. Grep-able detail: inputs-and-imports.md.
For when in the lifecycle to do this, 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 you edited a modules/ file, devenv.nix, or env.* and nothing changed. Resolves the lock + eval-cache staleness loop.
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.
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.
