Pre-Mortem Skill

Purpose: Is this plan/spec good enough to implement?

Mandatory for 3+ issue epics. Pre-mortem is enforced by hook when /crank is invoked on epics with 3+ child issues. 6/6 consecutive positive ROI. Bypass: --skip-pre-mortem flag or AGENTOPS_SKIP_PRE_MORTEM_GATE=1.

Loop position

Pre-flight check between moves 3 (slice plan) and 4 (TDD per slice) of the operating loop. Consumes the slice validation plan; produces a PASS/WARN/FAIL verdict on the plan AND on the wave-validity rows (distinct write scopes, no shared migration/contract/CLI surface, owner per slice, discard path per slice). A wave can only be claimed parallel if pre-mortem confirms every conflict-free row. FAIL on wave-validity → run slices sequential or send the plan back to /plan for re-slicing.

Run /council validate on a plan or spec to get multi-model judgment before committing to implementation.
