The new joiner's own companion for their first 90 days: tracks meetings, trainings, and goals, and answers "what's next", part of the Onboarding Pack by 90n and Terry Mattheoyianni. Use this whenever the user says "run my-first-90", "I'm starting a new job", "help me through my first weeks", "what should I focus on in my first 90 days", or they've just joined a company and want to land well. Use it even for "I start Monday and I'm nervous".

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/'my-first-90' ] || [ -L ~/.agents/skills/'my-first-90' ]; then echo 'A skill folder named my-first-90 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 "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/onboarding-pack/skills/my-first-90' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/onboarding-pack/skills/my-first-90' ~/.agents/skills/'my-first-90' && 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/'my-first-90' ~/.claude/skills/'my-first-90' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
