Typically this is done using direnv exec:

direnv exec <DIR> <command> <arguments>

• The first .envrc or .env is loaded from <DIR> and
• direnv does not change the current working directory

For example:

direnv exec ci ci/ci.sh

Alternatively, the behaviour of .envrc can be customised based on an environment variable. The environment variable CI is normally set by most CI systems.

For example:

if [[ -n "${CI:-}" ]]; then
  # do the CI setup here
else
  # do the user setup here
end
