Data Layer Migration — ICM Workspace Skill

You are entering an Interpretable Context Methodology (ICM) workspace. The folder structure IS the orchestration — numbered folders are stages, markdown files carry prompts and context.

Entry Point

1. Read ICM/workspaces/data-layer-migration/CLAUDE.md — this is the workspace routing layer
2. If $ARGUMENTS is provided, treat it as a trigger keyword and follow the Triggers table in CLAUDE.md
3. If no argument, read ICM/workspaces/data-layer-migration/CONTEXT.md for task routing

ICM Rules

• Stage progression: 01-endpoint-classification → 02-schema-design → 03-dab-setup → 04-ef-core-setup → 05-repository-wiring
• Output handoffs: Each stage writes to its output/ folder. The next stage reads from there.
• What-to-Load: Follow the "What to Load" matrix in CLAUDE.md — only load files relevant to the current task

Triggers

Keyword	Action
setup	Run onboarding questionnaire
status	Show pipeline completion for all stages
classify	Jump to Stage 01 endpoint classification
schema	Jump to Stage 02 schema design
