At a Glance

This skill turns raw business input into a board-ready visualization spec. It is structured as a portable SKILL.md package with references, proof examples, marketplace metadata, and local validation.

Layer What It Does File
Skill entrypoint Tells agents when and how to use the skill SKILL.md
Pattern library Selects the right executive visual visualization-patterns.md
Style system Defines palette, typography, layout, and chart rules style-system.md
Prompt templates Converts decisions and data into reproducible specs prompt-templates.md
Quality rubric Scores strategy, data, hierarchy, portability, and safety quality-rubric.md
Proof pack Shows input, expected output, and evaluation examples/
Marketplace layer Provides listing copy and metadata MARKETPLACE.md / manifest.json
Validation Checks package structure before publishing validate_skill.py

Why This Exists

Most AI-generated business charts become generic dashboards or decorative slide art. This skill gives agents a stricter operating system for strategy-consulting visualization:

  • insight-led headlines instead of descriptive titles
  • pattern selection tied to executive decisions
  • disciplined visual hierarchy, palette, typography, and density
  • explicit data assumptions and source-sensitive caveats
  • reusable slide specs that can be rendered by designers, agents, or presentation tools

What It Produces

The skill returns a structured deliverable:

Strategic question
Insight headline
Recommended visualization
Slide spec
Data and assumptions
Quality check

The output is meant to be useful before rendering. A consultant, designer, agent, or slide-generation tool should be able to use the spec without reverse-engineering the intent.

Visualization Patterns

Pattern Best For Example Decision
Time-series growth Momentum, adoption, revenue, usage Is growth accelerating?
Gap visualization Current vs. target, leader vs. laggard How large is the execution gap?
Before-after comparison Intervention impact Did the program justify investment?
Market share / adoption Penetration and composition Where is the center of gravity?
Investment / scale infographic Capacity, spend, reach, operating scale Who has the scale advantage?
Timeline Rollouts, regulation, milestones What must happen by when?
Contrast diagram Region, strategy, or model comparison Where is the structural difference?
2x2 strategic framework Positioning options or competitors Which position is attractive?
Competitive benchmark table Multi-criteria vendor or competitor review Who leads on what matters?
Waterfall chart Bridge, variance, cumulative change What drove the delta?
Cover slide Deck or section opening What is the argument?
Executive summary strip Compact board memo takeaway What should leaders remember?

Validate

Run the local package check before publishing, listing, or submitting changes:

python3 scripts/validate_skill.py

Expected output:

OK: skill package passed validation

The validator checks the marketplace-critical pieces:

    V --> F["Publishable package signal"]

Example Prompt

Use the strategy consulting visualization skill to turn this board update into five slide specs:
- ARR grew from $10M to $15M over four quarters.
- Enterprise expansion contributed $3M.
- Churn reduced revenue by $0.5M.
- AI workflow adoption grew from 18% to 64%.
- Forecast risk is concentrated in implementation capacity.

Proof Flow

The proof pack shows how a future marketplace reviewer or buyer can inspect the asset quickly.
