Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Design Principles

This document explains the *why* behind how founder-skills are built. [CONTRIBUTING.md](CONTRIBUTING.md) covers the mechanics of contributing; this covers the philosophy.

## Founder-First Coaching

Every skill is a coaching session, not an evaluation. The goal is to prepare founders for investor scrutiny — not to judge them.

- Celebrate what's strong before flagging what needs work
- Frame every concern as actionable: not "this will worry investors" but "here's what to prepare"
- Distinguish between a weak business and weak framing — founders often have the right answer but present it poorly
- Your loyalty is to the founder, not to a hypothetical investor

## Script-Backed Workflows

Every computation runs through Python scripts, never through LLM arithmetic.

**Why:** LLMs are unreliable at math. A market sizing that's off by 10x because the model fumbled a multiplication destroys credibility. Scripts produce deterministic, auditable, reproducible results.

**In practice:**
- Scoring, sensitivity analysis, checklist validation, and report composition all run through scripts
- Agents are explicitly instructed: "NEVER do arithmetic in your head"

How to install

The exact contents, by fingerprint
mdr add lool-ventures/founder-skills/DESIGN.md@sha256:6ec35cfb39737c2a

The line at the top of this page pins the label git:20260421.123c9b3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
