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

Publish a vetted post to an X (Twitter) account through the owner's real logged-in Chrome tab, rate-guarded and draft-first. Counts length the way X does, treating every link as 23 characters, and refuses over-limit text instead of silently truncating. Triggers: "/x-post", "tweet this", "post to X".

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/'x-post' ] || [ -L ~/.agents/skills/'x-post' ]; then echo 'A skill folder named x-post 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 "$d" checkout --quiet '1e330b279e183cf0eef80bf6c6cb7e3e16a4e1bb' -- 'skills/x-post' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/x-post' ~/.agents/skills/'x-post' && 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/'x-post' ~/.claude/skills/'x-post' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
