# Context
- Category: Marketing
- Use case: Write a monthly marketing performance summary with insights
- Source task:
  - I will paste this month's key marketing metrics. Analyse the data and produce a structured performance report:
  - 1. Executive summary (3 sentences : what happened, what mattered, what to do).
  - 2. Top 3 wins this month : with context on why each happened.
  - 3. Top 3 underperformances : with a hypothesis on root cause (not just observation).
  - 4. Metric-by-metric analysis : for each metric I provide, state: result vs target, trend vs last month, and one actionable recommendation.
  - 5. Priority actions for next month (ranked 1-3 with rationale).
  - Before writing, check if any metrics conflict with each other : if so, flag the inconsistency rather than ignoring it.
  - Metrics: {{paste_your_data_can_be_messy_include_targets_if_}}.

# Goal
A boardroom-ready performance summary that goes beyond reporting and makes recommendations

# Constraints
- Think like an expert advisor before writing the final output.
- Ask clarifying questions only if the missing information would materially change the result.
- Avoid generic filler, vague advice, and corporate-sounding language.
- Make the output specific, practical, and ready to use.

# Output
