Fine to try.

By polar-bear-org/claude-skills (GitHub) · design · 54 stars · scanned at commit 95f0180

Builds an Assumption Map that places the beliefs behind a decision by importance and by evidence held, names the risky unknowns to research first and says what a skipped study would put at risk. Use for "run uxr-assumption-map", "assumption mapping", "what are we assuming", "riskiest assumptions", "research got cut", "which bet are we making without evidence", "make the case for research", "importance vs evidence", part of the UX Research with Claude Pack by 90n.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'uxr-assumption-map' ] || [ -L ~/.agents/skills/'uxr-assumption-map' ]; then echo 'A skill folder named uxr-assumption-map already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/polar-bear-org/claude-skills' "$d" && git -C "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/ux-research-pack/skills/uxr-assumption-map' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/ux-research-pack/skills/uxr-assumption-map' ~/.agents/skills/'uxr-assumption-map' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'uxr-assumption-map' ~/.claude/skills/'uxr-assumption-map' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
