Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.
By himself65/finance-skills (GitHub) · coding · 3,537 stars · scanned at commit a085078
Look up Y Combinator companies and batches from the public yc-oss API, a static JSON dataset refreshed daily: company profiles, batch rosters (e.g. W25, S24), companies by industry or tag, top companies, who is hiring, founder-diversity lists, and overall YC stats. Use this skill whenever the user asks about YC-backed startups, a YC batch, YC companies in a sector or tag or that are hiring, the Y Combinator portfolio, or startup and venture research that draws on YC data. Read-only.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'yc-reader' ] || [ -L ~/.agents/skills/'yc-reader' ]; then echo 'A skill folder named yc-reader already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/himself65/finance-skills' "$d" && git -C "$d" checkout --quiet 'a0850786e72aa23b92862f9f1635b0de506fe206' -- 'plugins/social-readers/skills/yc-reader' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/social-readers/skills/yc-reader' ~/.agents/skills/'yc-reader' && 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/'yc-reader' ~/.claude/skills/'yc-reader' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
