What it means

Companion line to the Vercel turbo-ignore deprecation warning: prints the documentation URL for Vercel's built-in skipping of unaffected projects. Purely informational; emitted with hardcoded yellow ANSI escapes and a trailing newline as part of the deprecated-command notice.

Solutions

Follow the link and migrate to Vercel's built-in project skipping
Remove turbo-ignore from the Vercel build configuration

Defensive patterns

Strategy: fallback

Validate before calling

# Gate on the Vercel env before invoking the deprecated command
[ "$VERCEL" != "1" ] || exit 0   # rely on built-in skipping on Vercel
turbo-ignore

Prevention

Follow the printed link during migration planning
Remove the warning's source (turbo-ignore) rather than muting output

When it happens

Trigger: Same condition as the main deprecation warning: turbo-ignore invoked with VERCEL=1 in the environment (Vercel build step).

Common situations: Vercel builds where the operator needs the migration reference link shown in build logs.
