Know what to build. Build it with the why.
Seven guides for founders building with Claude Code, Cursor, Lovable or a developer. The practice first, then where it lives in MindBacklog.
Specs, PRDs and the Build Pack
Your agent builds for a default user unless you name the real one. These guides cover the document that does.
Spec-driven development for founders
What a spec needs when an agent is the reader: who, why, metric, must-haves with acceptance criteria, out of scope, known issues, done-when. Where the evidence comes from and how to keep the spec current. A worked example.

Every section of a Build Pack and what it means. The "not recorded" convention, the fenced-data rule and the security checklist. Three short examples of the format in full.

Why fast shipping ends in silence, the loop that goes around the agent, a weekly rhythm, what to keep outside the chat, and how a product map stops the re-breaking.
Read the guideEvidence, interviews and fit
What counts as evidence, questions that get real answers, and reading a PMF survey honestly.
The evidence ladder
Six rungs from praise to pays. What moves a belief, and why praise and your own words never count. Why AI tools agree with you, and how to run a pre-sale test with the pass line set first.
