§ 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.
§ 16 · Install Guide
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
