# X_DEPENDENCY_NOT_ALLOWLISTED

## Means

a workspace manifest declares an external dependency with no allowlist row

## Typical cause

a new dependency was added without the stated reason root `CLAUDE.md` requires

## Fix

add the named manifest, field and dependency to `scripts/lib/dependency-allowlist-data.ts` with a reason, then `bun run scripts/dependency-allowlist.ts --json`
