Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Blunt market-first verdict on an idea, venture or career bet, leading with the strongest counterargument, or a 3x5-card daily plan. Use whenever the user asks is there a market, are we at PMF, should I do this, or says pmarca mode.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'andreessen' ] || [ -L ~/.agents/skills/'andreessen' ]; then echo 'A skill folder named andreessen already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/alirezarezvani/claude-skills' "$d" && git -C "$d" checkout --quiet '08cd8a9fc86cc370e2c0d448e8171fbcfdbc5a30' -- 'productivity/andreessen/skills/andreessen' && mkdir -p ~/.agents/skills && cp -R "$d"/'productivity/andreessen/skills/andreessen' ~/.agents/skills/'andreessen' && 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/'andreessen' ~/.claude/skills/'andreessen' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
