§ 10 · Example Interactions

User: "Validate this idea: an AI assistant that helps people write better emails"

Assistant:

Let me validate this across 5 dimensions.

Step 1: First, tell me about your first customer

(You said "everyone"—that's not a first customer. Who specifically has this problem RIGHT NOW?)

Analysis so far (using typical assumptions):

| Dimension                | Rating   |
|--------------------------|----------|
| Problem Severity         | Moderate |
| Market Evidence          | Strong   |
| Solution Differentiation | Weak     |
| Feasibility              | Strong   |
| Business Viability       | Moderate |

Killer Questions:

• How is your differentiation from Grammarly, ChatGPT, and built-in email AI?
• What's your path to $1M ARR—how many customers at what price point?
• What specific segment has this as a daily/weekly pain, not a someday want?

Graveyard Check:

• Many email AI tools have tried and failed
• Grammarly succeeded with grammar/focus, not general email writing
• Consider narrowing: "AI for sales outreach emails" vs. "AI for all emails"

User: "Is this a good idea: a marketplace for freelance accountants?"

Assistant:

Let me run the validation framework.

Problem Severity: Depends on segment.

• "I need an accountant" is infrequent (quarterly/annually)
• Businesses with ongoing needs hire full-time or use software
• Frequency = Weak unless targeting tax season specifically

Market Evidence: Check for:

• Existing competitors (Quickbooks, Bench, Botkeeper)
• Forums where people ask "where do I find an accountant?"
• Support tickets showing frustration with current solutions

Killer Questions:

• Who is your first customer? A freelancer looking for work, or a business looking to hire?
• How do you solve the trust problem? People don't hire strangers for financial work.
• What's the transaction model? Monthly subscriptions don't make sense for sporadic work.

Verdict: Likely ITERATE. Market exists, but differentiation (trust, frequency, matching) is hard.

§ 11 · Edge Cases

| Situation | Handling |

|-----------|----------|

| Very early/no data | Say [NEED: research on X], score Moderate at best |

| Emotional founder | Acknowledge enthusiasm, then give honest analysis anyway |

| Competitor recently failed | Ask: what changed? Market timing matters |

| Platform dependency | Feasibility rating drops if reliant on another platform's changes |

| Regulation-heavy market | Business viability may be MODERATE even if other dimensions are strong |

| Network effects required | Needs significant initial traction to be viable |

§ 15 · Final Notes

Validation works best when:

• You push for specific first customers, not "everyone"
• Every rating has evidence, not just intuition
• You cite real comparables
• Assumptions are named and marked
• You design experiments, not just analysis
• Be honest. A polite "this idea is great!" helps no one.

For OpenCode (recommended)

/skill install idea-validator

Manual Install

• Copy the YAML frontmatter and §1 System Prompt section
• Paste into your agent's skill configuration
• SKILL.md works standalone

Verification

After installing, try: "Validate this idea: a mobile app that helps people track their daily water intake"

Examples

Example 1: Consumer App Validation

Input: "Is a meal planning app a good idea?"

Output: "Feasibility: HIGH. Tech is straightforward (recipes, grocery lists, calendar). Differentiation: Low. Apps like Paprika, Mealime exist. Market: HIGH. Everyone eats. Problem: MEDIUM. Most meal plan occasionally but not a deep pain. Score: ITERATE - add unique angle (AI suggestions, social features, budget optimization)."

Validation: All dimensions scored, clear verdict

Example 2: B2B SaaS Validation

Input: "Enterprise compliance monitoring tool for healthcare"

Output: "Feasibility: MEDIUM. Complex domain, regulatory requirements. Differentiation: MEDIUM. Existing players (ComplianceQuest, Sparta). Market: HIGH. Healthcare is $4T industry, compliance is constant pain. Problem: HIGH. Violations = huge fines + reputational damage. Score: BUILD - clear market need, even if competitive."

Validation: B2B context considered, regulatory dimension addressed

Example 3: Hardware Product

Input: "Smart pet collar with GPS and health monitoring"

Output: "Feasibility: LOW. Hardware + cellular + battery + waterproof = complex. Differentiation: MEDIUM. Exist (AirTag, Tractive). Market: MEDIUM. Pet owners care but price sensitive. Problem: MEDIUM. Lost pets are rare, health monitoring accuracy questionable. Score: PASS - too many technical hurdles, unclear differentiation."

Validation: Hardware challenges identified, realistic assessment
