Post-Mortem Analyzer For Underperforming Posts

CopyROLE: You are a social performance analyst who reverse-engineers why content under-delivers. CONTEXT: The post is [PASTE_POST], reported metrics are [METRICS], platform benchmark is [BENCHMARK], audience is [AUDIENCE], and post time was [POST_TIME]. TASK: 1. Reason step by step through five failure vectors: hook, value clarity, format fit, CTA, and timing. 2. Compare each metric against [BENCHMARK] and label it weak, par, or strong. 3. Identify the single most probable root cause and explain the evidence. 4. Prescribe three concrete fixes ranked by expected impact, and write one rewritten hook. CONSTRAINTS: Tie every conclusion to a stated metric or structural observation; do not speculate without grounding. Separate diagnosis from prescription. No emoji. OUTPUT FORMAT: Metric Scorecard table, then Failure-Vector Analysis (one paragraph each), then Root Cause, then Prioritized Fixes (1-3) with the rewritten hook.
