SHT 01 · REV AAN EXECUTION SYSTEM FOR AI-BUILT SOFTWARE
Plan once,
expensively.
Build cheap,
forever.
PRD Executor turns a plain-English app idea into a numbered build plan a budget AI coder can execute — step by step, verified, resumable. The expensive thinking happens once, where you can inspect it.

SHT 02 · THE ASSEMBLY LINE
Software, moved down a line — not lost in a chat.
Describe
Your app in plain English — the way you'd tell a friend. Reference designs welcome.
Plan
The strongest model you choose drafts everything: screens, APIs, schema, build order.
Inspect
The whole plan is a visible graph. Correct it while corrections still cost seconds.
Execute
A budget AI coder works the numbered steps — verified, resumable, a few dollars.
SHT 03 · THE ECONOMICS ARE THE POINT
Thinking is the expensive part.
Do it once.
A frontier model drafts the blueprint
Architecture, schemas, step ordering — the hardest thinking, done once by the strongest model you choose to pay for.
You sign off on the drawing
Every decision is on the graph before anything is built. A correction here costs seconds, not a rebuild.
A budget coder rivets it together
Cline, Cursor, or any MCP agent executes the numbered steps. Real plans from this tool — 437 steps, 79 steps — became working apps for a few dollars.
SHT 04 · THE AGENT INTERFACE
Your coder asks.
The plan answers.
One config entry connects Cursor, Claude Code, or Cline over MCP. From then on your agent pulls the next step, verifies its own work, and reports back — while the log fills with receipts, not promises.

SHT 05 · INSTRUMENTS
Built for the gap between an idea and a shipped app.
INS-01
Numbered steps, not vibes
The plan compiles into ordered implementation prompts — each small enough for a budget coder, each carrying its own verification check. “Done” means verified, not hoped.
INS-02
Memory that outlives the chat
Your agent reads architecture, schema, and current step live over MCP. Every session starts informed. Nothing is pasted, nothing is forgotten.
INS-03
The plan is inspectable
Screens, APIs, database tables, build phases — one navigable graph. You review the expensive thinking before a single line is built.
