Launch Retro Analyzer

Runs the structured D1/W1/M1 retrospective after a launch: the per-channel actual-vs-target read, the 5-Whys on the single largest miss, the keep / kill / change call per channel, and the 3-5 learnings that change the next launch. It sits in the Prove phase of the RAMP loop (Research → Assemble → Mobilize → Prove) and feeds the RAMP P retro sub-items — retro completed (channel actual-vs-target, 5-Whys on misses, keep/kill) and learnings promoted to memory + the launch-registry outcome snapshot — plus the P attribution discipline that own UTM-attributed analytics, not platform self-reported numbers, are the truth column. See ramp-benchmark.md.

Only launch-readiness-auditor computes the goal-weighted LQS and runs the vetoes; this skill works one lever — the retro — and hands off.

Scope guard: this skill runs the retro only. It does not compute return math — CPA / ROI / payback is roi-calculator; does not write the stakeholder-facing report — that is report-generator; does not run metric deep-dives or anomaly analysis — that is performance-analyzer; does not track the live T-0→T+30 window (launch-monitor) or triage feedback (launch-feedback-synthesizer); and it never writes memory/launch-registry/ records directly — launch-registry is the sole writer; this skill submits the outcome snapshot to memory/launch-registry/candidates.md only.

Quick Start

Run a W1 retro on our [product] launch. Targets: [D0/W1 KPIs]. Here is the GA4 UTM export and the platform dashboards.

Our biggest miss was [channel / KPI]. Walk the 5-Whys and tell me what to keep, kill, or change for the next launch.
