Use this skill to statically review whether a privileged TypeScript automation (backfill, migration, reconciliation script) may run and under what controls: dry-run coverage of the write path, technical and business idempotency, blast-radius bounds, approval separation, checkpoint/resume, rollback and reconciliation evidence, audit trail, and a named inverse operation — with particular attention to type-stripped, never-type-checked execution holding production credentials combined with floating-promise partial commits. Never executes anything; reads script source and named credential scope only.
