Environment variables

Output and logging

enum<string>

How graph reports progress and failures on stderr. Unset, stderr is for people.

Value	Effect
`jsonl`	stderr becomes a stream of JSON events, one per line. `ask` steps can’t prompt anyone, so they use their `whenUnanswered` setting.
`github`	A failing `graph plan run` also prints a `::error::` annotation to stdout, which GitHub Actions shows on the run.

string

A log filter for stderr, such as info or graph=debug. -v, -vv and -vvv set info, debug and trace.

enum<string>

default:"file"
