/validate
Validate a startup idea end-to-end: search KB, run Manifest alignment, S.E.E.D. niche check, Devil's Advocate inversion, STREAM 6-layer analysis, pick stack, generate PRD.
Philosophy: Validation should be honest, not optimistic. Better to kill a bad idea in 5 minutes than waste 3 months building it. The goal is truth, not encouragement.
MCP Tools (use if available)
If MCP tools are available, prefer them over CLI:
kb_search(query, n_results) — search knowledge base for related docs
project_info() — list active projects with stacks
web_search(query) — search for dead startups, competitor failures
If MCP tools are not available, fall back to Grep/Glob/WebSearch.
Steps
-
Parse the idea from $ARGUMENTS. If empty, ask the user what idea they want to validate.
-
Search for related knowledge:
If MCP kb_search tool is available, use it directly:
kb_search(query="<idea keywords>", n_results=5)
Otherwise search locally:
- Grep for idea keywords in
.md files across the project and knowledge base
Summarize any related documents found (existing ideas, frameworks, opportunities).
-
Deep research (optional): Check if research.md exists for this idea (look in docs/ or the current working directory).
- If it exists: read it and use findings to inform STREAM analysis and PRD filling (competitors, pain points, market size).
- If it does not exist: ask the user if they want to run deep research first. If yes, tell them to run
/research <idea> and come back. If no, continue without it.
-
Manifest Alignment Check (with teeth):
Consult references/manifest-checklist.md (bundled with this skill) for the full checklist of 9 principles and 6 red flags. Check the idea against EACH one. This is not a formality — a manifest violation is a soft kill flag.
For each principle, assess: comply or violate? If violating — cite the specific principle.
Key principles (see checklist for details):
- Privacy-first / offline-first
- One pain -> one feature -> launch
- AI as foundation, not feature
- Speed over perfection (MVP in days)
- Antifragile architecture
- Money without overheating
- Against exploitation
- Subscription fatigue
- Creators, not robots
Scoring: 0 violations = perfect, 1-2 = caution, 3+ = strong KILL signal.
Be honest. If the idea conflicts with principles, SAY SO. Don't rationalize alignment.
-
S.E.E.D. niche check (quick, before deep analysis):
Score the idea on four dimensions:
- S — Searchability: Can you rank? Forums/Reddit in top-10, few fresh giants, no video blocks?
- E — Evidence: Real pain with real quotes/URLs? Or hypothetical?
- E — Ease: MVP in 1-2 days on existing stack? No heavy dependencies?
- D — Demand: Long-tail keywords exist? Clear monetization path?
Kill flags (stop immediately if any):
- Top-10 SERP dominated by media giants or encyclopedias
- Fresh competing content (<60 days old) already covers it well
- No evidence of real user pain (only founder's hypothesis)
- MVP needs >1 week even on best-fit stack
If any kill flag triggers → recommend KILL with explanation. Don't proceed to STREAM.
-
Devil's Advocate (Inversion):
"Flip the question: how would you guarantee failure?" — STREAM Layer 3 (Inversion)
This step is mandatory — before scoring positively, actively try to kill the idea. The goal is to find reasons NOT to build it.
6a. Inversion — 5 ways this fails:
List 5 specific, concrete ways this idea could fail. Not generic risks ("competition") but specific scenarios with evidence:
- What specific competitor could crush this? (name, funding, strategy)
- What user behavior makes this unviable? (churn data, willingness to pay)
- What regulatory/legal event kills this? (specific laws, precedents)
- What technical limitation blocks this? (latency, cost, accuracy)
- What market dynamic makes the "opportunity" a mirage?
6b. Dead startup search:
Search for startups that tried something similar and failed or pivoted:
- WebSearch:
"<idea category>" startup failed OR pivoted OR shut down
- WebSearch:
"<competitor>" pivot OR layoffs OR shutdown
- If any found: what killed them? Does the same risk apply here?
6c. Unit economics stress test (if research.md exists):
Recalculate unit economics with PESSIMISTIC assumptions:
| Metric | Optimistic | Realistic | Pessimistic |
|---|
| Monthly churn | 10% | 30-40% (industry data) | 50%+ (first year) |
| Average lifetime | 10 months | 2.5-3 months | 1.5 months |
| LTV | (price × 10) | (price × 2.5) | (price × 1.5) |
| CAC | <$20 | $30-50 | $50-80 |
| LTV:CAC | >3:1 | ~1:1 | <1:1 (UNPROFITABLE) |
If pessimistic LTV:CAC < 1 → flag as critical risk.
6d. "Empty market" test:
If the analysis found an "empty" market segment or pricing gap, ask:
- Why is it empty? Is it opportunity or graveyard?
- Search for companies that tried this exact positioning and failed
- Is the segment empty because demand doesn't exist at that price point?
6e. Manifest conflict honesty:
Re-check findings from step 4. For each manifest violation found, state the conflict clearly: "This requires X, which violates principle Y because Z."
Do NOT rationalize conflicts away. The user decides whether to proceed — not the skill.
-
STREAM analysis: Walk the idea through all 6 layers.
Consult references/stream-layers.md (bundled with this skill) for the complete 6-layer framework with questions per layer.
For EACH layer, provide BOTH positive and negative assessment. Use the actual framework questions:
- Layer 1 (Scope): Map!=Territory, Simplicity, Boundaries — what assumptions are unproven?
- Layer 2 (Time): Entropy, Lindy — will this exist in 5 years?
- Layer 3 (Route): Inversion (use Devil's Advocate findings), Second-Order Effects — effects of effects?
- Layer 4 (Stakes): Asymmetry, Antifragility — real risk/reward with pessimistic numbers
- Layer 5 (Audience): Reputation, Network — deposit or withdrawal?
- Layer 6 (Meta): Mortality, Balance — worth finite time? Aligns with mission?
Scoring rules:
- Each layer scored 1-10
- If Devil's Advocate found critical issues, the affected layer score MUST be reduced
- If Manifest alignment has violations, Layer 6 (Meta) score MUST be reduced
- Final score = weighted average (Meta and Stakes weighted 1.5x)
-
Beachhead Segment (first target market):
From research personas (if available) or idea description, define the beachhead:
- Who exactly? — narrow segment, not "everyone" (e.g., "freelance designers earning $3-8K/mo", not "freelancers")
- Why them first? — accessible, high pain, willing to pay, can reach via specific channel
- Channel to reach them? — one specific channel (subreddit, community, newsletter)
- What adjacent segment next? — after beachhead is won, where to expand
This feeds into PRD ICP section and /launch GTM strategy.
-
Pricing Model (2-3 options with reasoning):
Based on competitor pricing (from research.md) and manifesto principles (subscription fatigue is real — prefer one-time purchase or honest transparent pricing when possible):
| Model | Price | Reasoning | Manifest Alignment |
|---|
| One-time | $X | No running costs → no recurring charge | Best fit (no lock-in) |
| Freemium | Free / $X/mo | Server costs justify subscription | OK if honest |
| Usage-based | $X per Y | Pay for what you use | Good (transparent) |
Rules from manifesto (templates/principles/manifest.md):
- If it doesn't cost to run, it should be free
- One-time purchase over subscription when possible
- Build the opposite of lock-in: tools users own, data they control
- No dark patterns, no artificial limitations to force upgrades
Pick the recommended model and explain why. Include in PRD.
-
Stack selection: Auto-detect from research data, then confirm or ask.
Auto-detection rules (from research.md product_type field or idea keywords):
product_type: ios → ios-swift
product_type: android → kotlin-android
product_type: web + mentions AI/ML → nextjs-supabase (or nextjs-ai-agents)
product_type: web + landing/static → astro-static
product_type: web + content site + needs SSR for some pages (CDN data, transcripts, dynamic) → astro-hybrid
product_type: web (default) → nextjs-supabase
product_type: api → python-api
product_type: cli + Python keywords → python-ml
product_type: cli + JS/TS keywords → nextjs-supabase (monorepo)
- Edge/serverless keywords →
cloudflare-workers
If auto-detected with high confidence, state the choice and proceed.
If ambiguous (e.g., could be web or mobile), ask via AskUserQuestion with the top 2-3 options.
If MCP project_info is available, show user's existing stacks as reference.
- Generate PRD: Create a PRD document at
docs/prd.md in the current project directory. Use a kebab-case project name derived from the idea.
PRD must pass Definition of Done:
- Output summary:
- Idea name and one-liner
- S.E.E.D. score (S/E/E/D each rated low/medium/high)
- Manifest alignment (X/9 principles met, list violations)
- Two scores:
- Optimistic score (0-10): best-case assumptions
- Realistic score (0-10): pessimistic unit economics, real churn, funded competitors
- Devil's Advocate top finding (the single strongest reason NOT to build)
- Key risk and key advantage
- Path to generated PRD
- "If I'm wrong about..." — state the single assumption that, if wrong, changes the verdict
- Recommended next action (one of):
/research <idea> — if evidence is weak, get data first
/scaffold <name> <stack> — if realistic score ≥ 7, build it
- Fake-Door Test — if realistic score 5-7, spend $20 on a landing stub before coding
- KILL — if realistic score < 5 or kill flags triggered
- PIVOT — if the idea has merit but current angle fails (suggest specific pivot)
Important
- Do NOT skip the Devil's Advocate step (step 6). It is mandatory.
- Do NOT skip reading
references/manifest-checklist.md and references/stream-layers.md (bundled with this skill). They contain the actual checklists.
- Quality and honesty are more important than speed. Take your time on steps 4, 6, and 7.
- A KILL recommendation is a valid and valuable outcome. It saves months of wasted effort.
When to use
- Before building anything non-trivial
- After
/research or /swarm to score and generate PRD
- When deciding between multiple ideas (run on each, compare realistic scores)
- When friends ask for feedback on their startup (be honest, not nice)
Common Issues
S.E.E.D. kill flag triggered
Cause: Idea fails basic niche viability (SERP dominated, no evidence, MVP too complex).
Fix: This is by design — kill flags save time. Consider pivoting the idea or running /research for deeper evidence.
No research.md found
Cause: Skipped /research step.
Fix: Skill asks if you want to research first. For stronger PRDs, run /research <idea> before /validate.
Stack auto-detection wrong
Cause: Ambiguous product type (could be web or mobile).
Fix: Skill asks via AskUserQuestion when ambiguous. Specify product type explicitly in the idea description.
Score seems too high
Cause: Confirmation bias — you found evidence FOR and stopped looking.
Fix: Devil's Advocate step is now mandatory. If you skipped it, the score is invalid. Re-run with full inversion.
Manifest conflicts rationalized away
Cause: The idea is exciting but conflicts with principles.
Fix: State conflicts explicitly. "This violates X because Y" is more useful than silence. The user decides whether to proceed — not the skill.
