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

Read this machine's cross-machine mailbox, the messages another computer's agent left here over a file-synced bus folder, and send messages back the same way. A session-start hook shows new mail automatically; this is the on-demand mid-session re-check. Triggers: "/inbox", "check inbox", "messages from the other machine".

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/'inbox' ] || [ -L ~/.agents/skills/'inbox' ]; then echo 'A skill folder named inbox already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/tonydzi/second-brain-starter-kit' "$d" && git -C "$d" checkout --quiet '1e330b279e183cf0eef80bf6c6cb7e3e16a4e1bb' -- 'skills/inbox' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/inbox' ~/.agents/skills/'inbox' && 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/'inbox' ~/.claude/skills/'inbox' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
