Example session with this skill installed
I want to build a subscription app for local gardeners to rent out high-end tools to their neighbors. Target is urban homeowners. I have no data yet, just the idea. Evaluate this.
- Read your context and instructions
- Compiled the startup idea reality
I have evaluated the peer-to-peer garden tool rental concept. The primary challenge is the high friction of physical logistics compared to the low frequency of use.
Startup Reality Check: Neighborhood Tool Share
| Category | Assessment |
|---|---|
| Target Customer | Urban homeowners with limited storage and occasional gardening needs. |
| Problem | High cost of specialized tools (tillers, aerators) for 1-2 uses per year. |
| Current Alternatives | Big-box retail rentals (Home Depot), buying cheap versions, or borrowing for free via Buy Nothing groups. |
| Monetization | Subscription-based (hard to justify for low-frequency) or Transaction-fee (logical). |
| Risk Level | High. Logistics, insurance for broken tools, and "last mile" pickup friction. |
Risk Register
- Operational: Liability for injury or tool damage during peer-to-peer exchange.
- Market: Hyper-locality requirement; you need high liquidity (many neighbors) in a small radius for it to work.
- Acquisition: High CAC to reach homeowners compared to the low lifetime value of occasional renters.
Validation Experiments
The "Doorstep" Test: Post on 5 local Nextdoor/Facebook groups offering 3 specific tools for rent. Don't buy them yet; see if anyone actually tries to book.
2.
The Friction Survey: Ask 20 target homeowners if they would drive >10 minutes to save $20 on a rental vs buying a cheap version on Amazon.
Verdict: REVISE
The subscription model is likely non-viable for this frequency of use. Focus on a transaction-based marketplace or a "managed" fleet to solve the trust and maintenance gap between neighbors.
Next steps
- Define the specific "hero" tools that justify the rental effort (e.g., power washers vs. hand trowels).
- Draft a simple landing page to collect emails in one specific zip code to test liquidity.
- Research existing "Tool Library" nonprofits to see why they struggle to scale.

About this skill
Founders often waste months building products nobody wants because they fall in love with a narrative instead of evidence. This skill provides a cold, analytical audit of startup concepts to identify fatal flaws before you write a single line of code.
What it does
- Problem validation evaluates the severity, frequency, and urgency of the target customer's pain point.
- Competitive analysis identifies current alternatives and assesses the realistic willingness of users to switch.
- Business model assessment audits monetization strategy, acquisition paths, and operational feasibility.
- Risk identification builds a register of technical, market, and execution risks that could sink the project.
- Evidence separation distinguishes between your attractive narrative and actual validated facts or data.
- Experimental design recommends the smallest, cheapest tests to increase or decrease confidence in the idea.
How it works
- Define the core by restating the idea into a structured customer, problem, solution, and business model format.
- Audit the fundamentals by testing differentiation and the feasibility of the proposed acquisition path.
- Verify external facts using available research tools to ensure market claims are grounded in current reality.
- Issue a verdict of Go, Revise, or Stop based on calibrated evidence rather than optimism.
Frameworks & tools
This skill uses lean startup methodology and risk-based validation frameworks. It is designed to work within Claude, ChatGPT, or any LLM environment with web search capabilities for market verification.
Why this beats prompting it yourself
Generic prompts often result in "yes-man" AI behavior that encourages every idea. This skill is hard-coded to prioritize cheap falsification and calibrated skepticism, ensuring you don't miss hidden assumptions or operational bottlenecks.
Use cases
- Pre-build auditing for indie hackers who need to decide which project to commit to next.
- Pivot evaluation for existing teams considering a major change in product direction.
- Pitch refinement to identify and address the exact questions investors will ask regarding market alternatives.
Known limitations
Does not provide legal or financial advice. Verification of external facts requires the agent to have active browsing or research tool access enabled.
Requires external research tools for real-time market data. Cannot provide legal or financial advice. Best for early-stage conceptual validation.
