Migrate From Legacy

Category: General  ·  Sub-category: orchestration-frameworks  ·  Last updated:
Migrate a Mycelium project from legacy install (npx-degit, framework files in .claude/) to plugin install (framework lives in plugin cache, .claude/ holds project state only). Detects current install form, walks the user through plugin installation, runs the migration script, and verifies project state survived. Idempotent — safe to invoke on already-migrated projects.

From the source SKILL.md

When this skill runs, walk the user through moving from legacy install to plugin install. The migration is non-destructive to project state: canvas, diamonds, memory, decision log, evals, and active metrics are preserved. Only framework reference content (skills, hooks, engine, scripts, schemas, etc.) is removed from .claude/ — that content now ships in the plugin cache.

What this skill does

Migrate From Legacy is a community-contributed Claude Code skill in the orchestration-frameworks sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/migrate-from-legacy/ and loads when your prompt matches the skill's trigger.
