Spec-to-Contracts Verifier
Build a SaaS and IDE plugin that converts ambiguous engineering requirements into machine-checkable contracts, edge-case scenarios, and verification-ready specs. The product addresses the largest bottleneck discussed: teams do not know what correct means well enough to prove it.
これが重要な理由
You are responsible for a service where outages, inconsistent state, or silent data loss are unacceptable, but when you try to verify behavior formally, you realize your team never wrote down what should happen in failure modes. Existing proof tools are useful only after the hard thinking is done. You still need to define retries, partial failures, ordering, and recovery behavior in a precise way. That specification work is slow, unpopular, and easy to postpone, which means verification never starts. A tool that turns messy product and engineering requirements into concrete contracts would let you move from vague intent to something a prover or test harness can actually check.
- · Engineering teams building distributed systems, fintech, infrastructure software, and security-sensitive services that want stronger correctness guarantees without hiring full formal-methods specialists.向けに構築。
- · 最も可能性の高い収益化モデル: SaaS subscription。

MVPの範囲 · 1～2週間
- Build a simple web form that ingests requirement text and outputs candidate invariants and pre/postconditions
- Create templates for distributed-system edge cases such as timeout, retry, duplicate request, and partial commit
- Implement a review UI where users approve, edit, or reject generated contracts
- Add export to Markdown and JSON schema for downstream tooling
- Interview 10 backend engineers and collect 20 sample requirement documents
- Add property-test skeleton generation from approved contracts
- Implement Lean or SMT-friendly contract export for a narrow subset
- Integrate GitHub import for PRD or design-doc text
- Track acceptance and edit rates to measure output quality
- Launch a private beta to 5 teams and collect weekly usage feedback

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Teams may enjoy the generated specs but stop before integrating them into real engineering workflows, limiting perceived ROI.
- 2Output quality may be too inconsistent for correctness-critical users, who have very low tolerance for subtle mistakes.
- 3Broader developer copilots may quickly add lightweight contract generation, compressing pricing power.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
The strongest pattern across the discussion was that proof itself is not the only problem. Several commenters emphasized that production systems fail because expected behavior is underspecified, especially around edge conditions. Multiple participants also noted that the cost of detailed thinking has historically blocked formal methods. That creates room for a software product focused on specification generation, edge-case surfacing, and verifier-ready contracts rather than raw proof automation alone.
