Corrects the wrong defaults a capable model has when building Yjs collaborative editing into a Next.js 16 App Router app with tRPC v11 and shadcn/ui — pinned to Yjs 13.6.31. Covers the decisions whose failure mode is silence rather than an error — plain objects in a Y.Map discarding concurrent edits, updates that vanish because a JSON boundary turned a Uint8Array into a number array, undo that reverts a colleague's paragraph, initial content seeded once per client, and carets thrown to the end …

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/'yjs-nextjs' ] || [ -L ~/.agents/skills/'yjs-nextjs' ]; then echo 'A skill folder named yjs-nextjs already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/pproenca/dot-skills' "$d" && git -C "$d" checkout --quiet 'cf93c57cac89d6fc3e4194686000411567f5caf3' -- 'skills/.experimental/yjs-nextjs' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/.experimental/yjs-nextjs' ~/.agents/skills/'yjs-nextjs' && 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/'yjs-nextjs' ~/.claude/skills/'yjs-nextjs' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
