Domain Mapper

Extract domain expertise from conversation and structure it for product creation.

When to use: Before /create for complex products, when creator has deep domain knowledge to encode, or when exploring what to build.

When NOT to use: For simple products where the creator already knows exactly what to build. Skip to /create instead.

Activation Protocol

0. Shared preamble: Load

   references/quality/activation-preamble.md

   — context assembly, persona adaptation, deterministic routing rules.
1. Read

   creator.yaml

   — load creator expertise domains and technical level. If missing → "Creator profile not found. Run

   /onboard

   first." and stop.
2. If

   $ARGUMENTS

   provided, use as domain topic seed
3. If previous

   domain-map.md

   exists in workspace, load as context
4. Begin structured knowledge extraction
5. Load voice identity: Load

   references/quality/engine-voice-core.md

   . Every user-facing line in this skill honors the ✦ signature, three tones, and six anti-patterns. 5b. Load UX vocabulary: Load

   references/ux-vocabulary.md

   — translate all internal terms before creator-facing output. 5c. Load proactives: Load

   references/engine-proactive.md

   — wire #1 (pipeline guidance: after map, suggest /create with domain context).

Core Instructions

KNOWLEDGE EXTRACTION FLOW

Ask questions in 3 phases. Adapt depth to creator's technical level (from creator.yaml).

Phase 1 — Domain Boundaries (3 questions)

1. What specific domain does this product operate in?
   (e.g., "code review for React apps", "database migration safety")

2. Who is the target user? What do they know? What do they struggle with?

3. What existing approaches/tools address this? What's missing?

Phase 2 — Expertise Mining (4 questions)

4. What are the top 5 things someone MUST know in this domain?
   (The non-obvious knowledge that separates experts from beginners)

5. What are the most common mistakes/anti-patterns in this domain?
   (Things that seem right but cause problems)

6. What decision framework do experts use?
   (How do they decide between options?)

7. What terminology is essential?
   (Terms the product must use correctly)

Phase 3 — Product Shape (2 questions)

8. What would a perfect output look like for this product?
   (Describe the ideal result after using the product)

9. What are the edge cases — situations where the standard approach breaks?

SYNTHESIS

After all questions are answered:

1. Structure the knowledge into domain-map.md:

   # Domain Map: {domain}
   Created: {date} | Creator: {name}
   
   ## Domain Boundaries
   - Scope: {what's in / what's out}
   - Target user: {profile}
   - Competitive landscape: {existing approaches}
   
   ## Core Knowledge (5 pillars)
   1. {pillar}: {explanation}
   ...
   
   ## Anti-Patterns
   1. {mistake}: {why it's wrong} → {correct approach}
   ...
   
   ## Decision Framework
   {structured decision tree or matrix}
   
   ## Vocabulary
   | Term | Definition | Usage Context |
   ...
   
   ## Ideal Output
   {description of perfect product output}
   
   ## Edge Cases
   1. {case}: {how to handle}
   ...
   
   ## Recommended Product Type
   Based on this domain, I recommend: {type} because {reason}
   Alternative: {type} if {condition}
   

2. Save to

   workspace/domain-map.md

   (or

   workspace/{slug}/domain-map.md

   if product exists)

3. Recommend next step:

   Domain mapped! Your knowledge covers {N} pillars and {M} anti-patterns.
   
   Recommended: /create {type} — this domain maps best to a {type} product.
   The domain map will be automatically loaded during creation.
   

Phase 4 — Elicitation Deepening (optional)

After synthesis, offer 3 methods to deepen the map:

• Inversion: "What would make a product in this domain fail completely?"
• Stakeholder Lens: "How would a [beginner/expert] see this domain differently?"
• First Principles: "Strip all assumptions. What's the irreducible core?"

Creator selects one or skips. Apply selected method to enrich the domain map before saving. If skipped, save immediately and proceed to next step recommendation.

Quality Gate

Before saving domain-map.md, verify:

• At least 3 of 5 knowledge pillars have substantive content (not placeholder)
• At least 3 anti-patterns documented
• Decision framework has at least 2 decision points
• Target user clearly defined
• Recommended product type provided with reasoning

Anti-Patterns

1. Shallow extraction — Accepting one-word answers. Push for specifics: "Can you give me an example?"
2. Domain overload — Trying to map too broad a domain. Narrow: "Let's focus on the most impactful subset."
3. Creator fatigue — Too many questions. If creator seems tired, consolidate remaining questions.
4. Assumed knowledge — Don't fill in answers the creator didn't give. Ask, don't assume.
5. Generic output — If domain-map reads like any AI could generate it, push deeper: "What do YOU know that's specific to your experience?"
