before-you-build from onewave-ai/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use before starting a product, feature, MVP, agent, automation, or integration build to identify the main pre-build risk and choose the smallest validation step. Trigger when the user asks whether to build, scope, validate, prioritize, or sanity-check an idea before implementation.
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
# Before You Build Use this skill as a short pre-build risk gate. The goal is to stop implementation from starting before the riskiest product assumption is clear. Stay implementation-agnostic: do not recommend stacks, architectures, tools, or code. ## Core Behavior When invoked: 1. Restate the idea in one sentence. 2. Identify the dominant pre-build risk. 3. Give a short risk verdict. 4. Recommend the smallest validation step that can reduce uncertainty before building. Keep the response short unless the user explicitly asks for a deeper review. ## Seven Risk Dimensions Check the idea through these dimensions: - Demand risk: Do enough people already feel this problem strongly? - Buyer risk: Is there a clear person or team with reason to pay or commit? - Distribution risk: Is there a believable path to reaching those people? - Workflow risk: Does the idea fit how users already behave, decide, or work? - Timing risk: Is this urgent now, or only interesting in theory? - Trust risk: Does the product require data, access, behavior change, or credibility users may not grant? - Scope risk: Is the proposed build larger than the proof needed right now? …

How to install
mdr add onewave-ai/claude-skills/before-you-build@sha256:4099517062ff747eThe line at the top of this page pins the label git:20260617.071454b, 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.
