Validate app/startup ideas with market, feasibility, commercial, and open-source competitor analysis. Use when asked to evaluate, validate, or score a product idea. Don't use for PRDs, go-to-market plans, or investor decks.
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
# Idea Validator Critically evaluate ideas with honest feedback on market viability, technical feasibility, and actionable improvements. ## When to Use Trigger this skill when the user asks to: - Evaluate, validate, or score an app idea or startup concept - Get honest feedback on whether an idea is worth building - Research what competitors already exist in a space, including commercial tools/services and open-source alternatives - Turn a vague concept into a structured validation report ## Instructions Run the steps in this order: Setup → Phase 1 Clarify → Phase 2 Technical Context → Phase 3 Competitive Landscape → Phase 4 Evaluate → Phase 5 Improve → Commit and Push → Final Report. Do not skip or reorder a step, except where an Edge Cases row says to stop. A stop after Setup step 4 still runs Commit and Push on the files written so far, then the Final Report. If the ideas root is the root of an `ideas` repo, also run README Maintenance after each file update (detection rule in that section). Terms used throughout: - **Ideas root** — the directory that holds every idea folder (resolved in Setup step 2). …

How to install
mdr add luongnv89/skills/idea-validator@sha256:a057dda9d2ba94b7The line at the top of this page pins the label v1.6.0, 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.
