What problem does it solve?
It solves the problem of legacy Y3Maker/CodeMaker helper systems being incompatible with Claude Code’s native project structure, causing fragmented knowledge, broken paths, and unreliable MCP configuration.
Core Features & Use Cases
- Workspace inventory & migration planning: Detects which legacy and Claude Code surfaces exist and prepares a detailed migration plan without touching the original
.y3maker/.
- Idempotent apply with safe merge semantics: Creates or updates
.claude/ copies, normalizes SKILL.md frontmatter, rewrites legacy path references, and records outcomes in .claude/migration/y3maker-manifest.json.
- Optional MCP configuration conversion with explicit user control: Converts
.y3maker/mcp_settings.json into either project-level .mcp.json, user-level ~/.claude.json, or skips—without silently modifying MCP config.
Quick Start
Run the skill for a dry run on your workspace to preview what it would create or update: node "./scripts/run-migration.js" apply --workspace "." --dry-run --mcp-scope project --pretty
