Error message

workflow requires dry_run=true; provider execution is disabled

What it means

run_workflow enforces the deterministic offline contract: candidate execution is disabled on every OS because no verified containment backend exists, so the workflow config must set dry_run=true and any provider-execution request is refused.

Solutions

1. Set "dry_run": true (boolean) in the workflow config
2. Remove the dry_run key entirely — true is the default
3. If provider execution is needed, use a build/version of the tool that enables it

Example fix

// before
"dry_run": false
// after
"dry_run": true

if config.get("dry_run", True) is not True:
    raise SystemExit("dry_run must be boolean true in this build; provider execution is disabled")

def is_dry_run(config: dict) -> bool:
    return config.get("dry_run", True) is True

try:
    run_workflow(config)
except ValueError as e:
    if "dry_run" in str(e):
        config["dry_run"] = True
        run_workflow(config)
    else:
        raise

When it happens

Trigger: Config contains "dry_run": false, or a truthy non-true value like "true" (string) or 1, which fails the strict `is not True` check.

Common situations: Users flipping dry_run to false expecting provider calls to work; YAML/JSON writers emitting the string "true"; older configs predating the dry-run-only enforcement.
