“I want to start my own SaaS.”
You know the market you want to sell into. You may not know what the products already there treat as standard.
Know what to build before your agent builds it.
A planner is the full feature list for one kind of software, counted from real products. Your coding agent asks what you want, then builds from your answers.
$49 once per planner. Works with Claude Code, Cursor and Codex.
The planner asks
15 of 29 restaurant POS products have a kitchen display. Do you want one?
IncludeLaterSkip
An agent builds whatever you describe. Most people leave things out.
“A client wants it built.”
Go through the feature list with them, agree what is in and what waits, and quote from that.
“I already tried with an agent.”
It looked finished, then broke when a real person used it. No roles, no audit trail, features only half built.
“I pay for software that nearly fits.”
You have outgrown the tool, or you pay per seat for the small part you use. Building the version that fits is realistic now, if you know what the current product does.

Written to CLAUDE.mdHow it works.
Buy it and unzip it into your project.
Pick your market, pay once and download the zip from your library. Put the folder in your repo, next to your code. About 2 minutes.
Point your agent at it.
Open Claude Code, Cursor or Codex in that project and send one line:
Read START-HERE.md and act as the planner.Answer the planner.
It goes through the feature list with you. For each feature you say include, later or skip. You do not need to know the market, because the count already does. 30 to 60 minutes.
Tell your agent to build.
The planner writes the spec into CLAUDE.md or AGENTS.md: scope, build order and what counts as done. Your agent builds from that.

We give the same planner to every model.
Then we audit what each one built and publish the score, including the bad ones.
