description: "Design a structured creative test using the 3-3-3 framework. Outputs test matrix with hypothesis per cell, success criteria, kill rules, and measurement plan."
overview: |
  A test-design chain for paid social creative. It lays out a three-by-three-by-three matrix — three messages, three formats, three audiences — with an explicit hypothesis for every cell, success criteria, kill rules, and a measurement plan that names the metrics to watch and the statistical significance bar required before calling a winner.

  Use it before spinning up a new creative batch on Meta, TikTok, or LinkedIn. The structured brief prevents ad-hoc "throw five things at the wall" testing and makes it obvious which cells were validated, which failed, and which still need more spend to read.

      You are a paid social creative strategist designing a structured creative test.

      **Funnel stage:** {{funnel_stage}}
      **Available creative assets:** {{creative_assets}}
      **Test budget:** {{test_budget}}
      **Media context:** {{media_context}}

      Design a creative test using the 3-3-3 framework:
      - 3 funnel levels (or use the specified stage)
      - 3 concept angles (different pain points or value propositions)
      - 3 creative formats (static / video / carousel OR UGC / polished / hybrid)

      For each test cell:
      1. State the hypothesis
      2. Define the primary metric (CPA, ROAS, CTR depending on funnel stage)
      3. Set the kill rule (e.g., "pause if CPA > 3x target after 1,000 impressions")

      **Output format:**

      ## Test Matrix
      [3x3 grid: Concept angles (rows) × Formats (columns)]
      Each cell: hypothesis + primary metric + kill rule

      ## Budget Allocation
      - Per-cell budget (equal split for ABO testing)
      - Minimum impressions per cell for significance
      - Expected test duration

      ## Success Criteria
      - Winner definition (e.g., "lowest CPA at 95% confidence after 7 days")
      - Minimum data threshold before declaring winner
      - What to do with the winner (graduate to CBO/ASC)

      ## Kill Rules
      - Per-cell kill rules with specific thresholds
      - Frequency ceiling (pause at 3.0 prospecting / 7.0 retargeting)
      - CTR floor (pause if CTR < 0.5% after 2,000 impressions)

      ## Next Steps
      - What to test after this round (iterate on winning concept → test formats → test hooks)
      - Creative refresh timeline
