Run product discovery to identify what to build. Use when the user says "product discovery", "how do I know what to build", "validate this idea", "talk to customers", "are we building the right thing", "discovery process", or wants to reduce the risk of building something users don't want - even if they don't say "discovery".
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
## Overview
Based on **Inspired** by Marty Cagan (Silicon Valley Product Group). Cagan's central argument: the biggest risk in product is not execution risk - it's value risk (will users buy it?), usability risk (can users figure it out?), feasibility risk (can we build it?), and business viability risk (does it work for the business?). Discovery is how you tackle all four before writing a line of code.
The best product teams run discovery and delivery in parallel. Discovery is not a phase - it's a continuous habit.
## Workflow
### Step 1: Identify the four risks
For the idea or problem at hand, assess:
- **Value risk** - Do users actually want this? Will they use it?
- **Usability risk** - Will users understand how to use it?
- **Feasibility risk** - Can the team build it with current skills and tech?
- **Viability risk** - Does it work legally, financially, and ethically for the business?
Rate each: High / Medium / Low. Focus discovery on High risks.
### Step 2: Frame the opportunity (not the solution)
State the problem as an opportunity: "Users struggle to [X], which causes [Y impact]."

The line at the top of this page pins the label git:20260303.e2bea1e, 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.
