The governed turn-off primitive — no legacy component is severed until its replacement has PROVEN independence and the old side is provably safe, recorded in an append-only operator-bound validation ledger the gate RE-DERIVES from live re-checks at turn-off time (fail-closed, waiver-blind). Drives scripts/foundry-decommission.py: validate-register (class-aware register, GENERATED gate_status), record (append-only ledger; refuses incomplete VALIDATED rows incl. the custody real-operation proof), gate-check (GO only on latest-VALIDATED + live reverify/old-safe re-checks under a forced waiver-blind phase; else NO-GO exit 1). Turn-off is structurally the LAST wave. Trigger: "decommission", "turn off the legacy", "is it safe to delete", "sever the old side", "/foundry:decommission-gate".

From the source SKILL.md

Turn-off is the one irreversible, highest-blast-radius action of a migration. This skill governs it with three machine-checkable stages driven through scripts/foundry-decommission.py. The gate consumes a recorded design principle: a persisted "validated" flag alone NEVER authorizes a sever — GO is re-derived from live re-checks at the moment of turn-off.

What this skill does

Decommission Gate is a community-contributed Claude Code skill in the mobile sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/decommission-gate/ and loads when your prompt matches the skill's trigger.
