SpecForge is a structured interview tool that turns your product idea into the markdown files AI coding agents need to build what you actually want — on the first try.
You describe what you want. The agent builds something close but wrong. You correct it. It overcorrects. Twelve rounds later you have code that mostly works, a context window full of confusion, and no record of any decision ever made.
The problem isn't the AI. The problem is the input. Agents need structured, precise specs — the kind that used to require a senior developer to write. SpecForge writes them with you.
Download the HTML file and open it in any browser — no account, no internet connection required. Answer plain-language questions about your product: what it does, who it's for, what features you need, and how it should look and feel.
Add the skill file to a Claude Project or paste it into a new chat. The skill teaches Claude how to read your answers, identify gaps, and generate complete spec files — not just a summary.
Claude reads what you filled in, asks only the follow-up questions that are genuinely needed, and fills in everything you missed — edge cases, state inventories, validation criteria, data schemas.
Claude generates ready-to-use markdown files formatted for your AI coding tool of choice. Drop them in, open your agent, and start building — with the agent fully briefed from session one.
AI agents are stateless — every session starts blank. A Constitution loaded on boot anchors the agent to your architecture immediately, without re-explaining everything from scratch.
The most expensive part of vibe coding isn't the tokens — it's the 10–15 rounds of misaligned output. A precise spec front-loads all clarification so the agent executes correctly from the start.
You don't need to know what a carousel is called to spec one correctly. SpecForge asks the right questions in plain language and writes the technical spec for you.
Download the interview form and the Claude skill. Fill in the form, paste your answers, get your spec files. Takes about 20 minutes. Saves hours of back-and-forth.
No account required. No email. Just two files.
SpecForge is early. The interview questions are opinionated but not perfect — there are gaps, unclear prompts, and edge cases that aren't covered yet. Your feedback on a real project directly shapes what gets fixed next.
