| description | Migrate or modernize legacy systems using Spec-Driven Development (SDD). Use when migrating between platforms, modernizing legacy code to current-generation stacks, or performing cross-platform migrations. Assesses legacy capabilities, maps to target platform, forms specialized agent team, and delivers verified migration with parity testing and confidence scoring. |
Modernization & Migration
Run the modernization workflow to migrate platforms or modernize legacy systems using Spec-Driven Development (SDD).
When to Use This Skill
- User requests MIGRATING from one platform/technology to another
- User wants to MODERNIZE legacy systems to current-generation stacks
- User says "migrate to" or "modernize from"
- User needs legacy-to-target gap analysis and migration planning
What This Skill Does
This skill delegates to the authoritative modernization workflow at .github/prompts/modernization.prompt.md, which orchestrates:
- Intake & Clarification — Capture migration request, choose execution approach (Custom Agents or Squad), select optional SDD framework
- Discovery — Inventory legacy system and generate repo-wiki for context
- Assessment — Map legacy capabilities to target state, identify gaps and migration risks
- Analysis — Decompose migration into phases and validation requirements
- Capability Mapping — Identify required skills, MCP servers, instructions
- Capability Acquisition — Discover or build missing capabilities
- Team Formation — Assign capabilities to agent roles, define handoff DAG
- Execution — Execute migration iteratively with parity testing and reviewer gates
- Verification — Validate deliverables, ensure parity, calculate confidence score
- Handoff — Generate progress report and package migration artifacts
Read and execute .github/prompts/modernization.prompt.md in full — it is the single source of truth for the modernization workflow.
VS Code Users
VS Code users can invoke this workflow directly via the /modernization slash command instead of using this skill. Both surfaces share the same authoritative prompt file.
