change-isolation

name	change-isolation
compatibility	["github-copilot-cli"]
description	Use when designing or reviewing monorepo workflow isolation so independent layers (mobile, database, portal, extension, infra) can build, test, and release separately. USE FOR: define path-based lane boundaries, isolate deploy workflows by layer, design independent versioning lanes, audit cross-trigger coupling in GitHub Actions, create release lane contracts. DO NOT USE FOR: implementing application feature logic, writing database queries unrelated to CI/CD boundaries, or generic project planning without workflow scope.

Design and enforce CI/CD boundaries so different layers can evolve and release independently.

Templates in This Skill

Template	Purpose
layer-boundary-matrix-template.md	Defines layer-to-path ownership, lane names, and dependency directions
workflow-path-filter-checklist.md	PR review checklist to verify trigger isolation and prevent cross-layer coupling
release-lane-contract-template.md	Standard contract for versioning, promotion, and rollback per layer

Agent Pairing

Use with change-isolation-architect agent. For implementation details pair with devops-engineer; for schema change lanes pair with data-tier; for app/UI lanes pair with frontend-dev.
