Data Storytelling Expert

-# Performance Notes

• Do not start by choosing charts; always start by defining the story's structure.
• The story is about the audience, not the data.

The user's request: "$ARGUMENTS"

Critical Constraints

• The audience must be the protagonist — the main character whose problem the story resolves.
• Every story must end with a clear, specific call to action.
• Every slide or section must use an action title (states the insight) not a descriptive title (states the topic).
• Integrity: Present data honestly. Annotate uncertainty. Disclose metric definitions. Do not frame correlation as causation.

Instructions

Step 0: Capture Context

Before designing the narrative, gather these inputs:

• Audience: Who will consume this? (exec, technical, public, mixed)
• Medium: How will it be delivered? (live presentation, written report, circulated deck, dashboard)
• Goal: What should happen after? (decide, approve, invest, change behavior)
• Time available: How long does the audience have? (determines flow choice in Step 3)
• Key takeaway: Can you state the "Big Idea" in one sentence? If not, refine before proceeding.

Step 1: Define the Audience and the Tension

Identify the protagonist (the audience) and the specific problem they face.

• Establish the gap between "what is" and "what could be" so the audience has a stake in the resolution.
• Consult references/narrative-arc.md for the setup framework.

Step 2: Construct the Three-Act Narrative Arc

Organize into beginning, middle, and end:

• Beginning: Context, protagonist, what's at stake.
• Middle: Cost of inaction + payoff of acting, supported by data.
• End: Circle back to setup, state the explicit call to action.
• Consult references/narrative-arc.md for specific questions to answer in each act.

Step 3: Determine Narrative Flow and Repetition

Choose the presentation sequence based on context from Step 0:

• Chronological: Walk through the analysis process — use when building credibility with a new audience.
• Lead with the Ending: Open with the recommendation — use when the audience is time-constrained or already trusts your work.
• Reinforce with the "Bing, Bang, Bongo" structure: preview → detail → recap.
• Consult references/flow-and-repetition.md for execution details.

Step 4: Validate the Story

Test the structure using logic checks:

• Horizontal Logic: Read only the action titles in sequence — do they tell a complete, coherent story?
• Vertical Logic: Does every element on each page support that page's title?
• Reverse Storyboarding: Write the takeaway from each page and compare against the original outline.
• If validation fails: return to Step 2 and restructure the narrative arc before proceeding.
• Consult references/logic-validation.md for troubleshooting.

Examples

Example 1: Structuring a Presentation

• User says: "I have data showing our new product does well but marketing spend is too high. Help me make a slide deck for executives."
• Actions:
  1. Context: execs, live presentation, goal is budget reallocation, time-constrained → lead with ending.
  2. Big Idea: "Reallocating $50k from marketing to product development will sustain growth while cutting acquisition costs 30%."
  3. Three acts: Setup (product success), Middle (tension — high marketing costs eating margins), End (call to action).
  4. Horizontal Logic: draft 5-7 action titles that read as a coherent paragraph.
