You hand it an idea, a feature request or a scope change; it returns a Build Risk Review: one primary risk tagged from a taxonomy, up to five supporting risks, an evidence ledger, a verdict and a concrete no-code validation step. The verdict is exactly one of four: Build small, Validate first, Pivot first, Don't build yet. Two modes. Pre-build covers a new idea or MVP, where demand and distribution usually carry the risk. Feature-change covers feature requests and competitor-copying, and uses a demand hierarchy from L0 to L4: founder anxiety or "competitors have it" sits at L0, a single user asking at L1, a workflow blocker at L3, a revenue or retention blocker at L4. Building right away is usually justified only at L3 or L4. Likes, compliments and waitlists do not count as demand — real files, payment, booked calls and repeated manual use do. The skill writes no code, recommends no stack and designs no implementation. If the work is declared as learning, a portfolio or internal practice, market standards do not apply, though scope and clarity risks still get flagged. It then routes to the next skill: `define-hypothesis` after Validate first, `foundation-lean-canvas` after Pivot first. The library is often installed in part, so when a routed skill is missing from your environment the skill inlines a minimal version of its output instead of a bare pointer. Worth checking which `pm-skills` you actually have. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add product-on-purpose/pm-skills --skill foundation-build-risk-review -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/foundation-build-risk-review/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/foundation-build-risk-review/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add product-on-purpose/pm-skills --skill foundation-build-risk-review -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/foundation-build-risk-review/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add product-on-purpose/pm-skills --skill foundation-build-risk-review -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/foundation-build-risk-review/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install product-on-purpose/pm-skills foundation-build-risk-review ``` 2. **Manually: put the files in place** - File: `.github/skills/foundation-build-risk-review/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add product-on-purpose/pm-skills --skill foundation-build-risk-review -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/product-on-purpose/pm-skills --path skills/foundation-build-risk-review ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/foundation-build-risk-review/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add product-on-purpose/pm-skills --skill foundation-build-risk-review -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/product-on-purpose/pm-skills/tree/HEAD/skills/foundation-build-risk-review/SKILL.md ## When to use it - separate real demand from one polite request - name the single assumption that would kill a feature - decide whether to expand scope right now - plan a no-code validation step before writing code - grade demand signals by strength ## Example prompts - Run foundation-build-risk-review on this idea: PDF export for reports - Users keep asking for dark mode — should we build it? Give me a risk review - We want to expand scope to a mobile app. What's the verdict? ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE a290217ae3a80aeb ```text --- name: foundation-build-risk-review description: Runs a fast pre-build risk review on a product idea, feature request, or scope change, naming the single assumption most likely to make it fail and returning a clear verdict (build small, validate first, pivot first, or don't build yet) with a no-code validation step. Use before committing build effort, when triaging whether to honor a feature request, or when deciding whether to expand scope, ahead of writing a PRD. For a launched product's pivot-or-persevere decision, use iterate-pivot-decision instead. license: Apache-2.0 metadata: classification: foundation version: "1.1.0" updated: 2026-08-16 category: problem-framing frameworks: [triple-diamond, lean-startup] author: product-on-purpose --- # Build Risk Review Don't build it yet. First name the one assumption most likely to make it fail. `foundation-build-risk-review` is a fast, pre-commitment gate for product decisions. Given an idea, a feature request, or a scope change, it returns a **Build Risk Review**: the single biggest risk, the evidence behind it, a verdict, and a concrete no-code validation step, then routes you to the skill that does the next piece of work. It is a foundation hub: its job is to triage and dispatch, not to duplicate the deeper skills. ## Hard gate Do not write code, scaffold a project, recommend a stack, or design implementation. First answer three things: should this be built, what is most likely to make it fail, and what must be validated before committing. If the user says the work is for learning, a portfolio, or internal practice, do not judge it by market standards; still flag scope and clarity risks. ## When to Use - A product idea, MVP, or new bet is about to turn into build work. ``` END THIRD-PARTY FILE a290217ae3a80aeb The third-party file has ended.
