Move code out of `libs/` or `apps/*/src` into the layers (`shared/`, `domain/`, `features/`) in three steps, addition, deprecation and deletion, and give a new-architecture package what only legacy code provides through injection (ports, thunk `extraArgument`) instead of an import. Use when moving, extracting or porting code out of `libs/` or `apps/*/src`, replacing a legacy module with a new package, deprecating or deleting legacy code, or when a new package seems to need a `libs/` import.

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/'legacy-migration' ] || [ -L ~/.agents/skills/'legacy-migration' ]; then echo 'A skill folder named legacy-migration already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LedgerHQ/ledger-live' "$d" && git -C "$d" checkout --quiet 'fc34951404624cf04905a2bacef9f44ac179f050' -- '.agents/skills/legacy-migration' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/legacy-migration' ~/.agents/skills/'legacy-migration' && 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/'legacy-migration' ~/.claude/skills/'legacy-migration' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
