# Medassist Config Change Guard > Validate MedAssist configuration changes across env vars, Docker compose, proxy settings, and runtime defaults, including equivalent requests phrased in German. Use when this capability is needed. - Skill: `tomevault-io/medassist-config-change-guard` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/medassist-config-change-guard` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/medassist-config-change-guard/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: DevOps & Infra - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/medassist-config-change-guard --- # Skill Instructions Use this skill when changes touch `.env`, Docker files, Vite proxy settings, runtime defaults, or app startup behavior. ## Objective Prevent configuration drift and broken local/CI environments. ## Required Checks 1. New/changed config has safe defaults. 2. Env changes are backward-compatible where feasible. 3. Docker/dev runtime changes remain consistent across services. 4. Frontend/backend URL/proxy conventions remain valid (`/api/*`). 5. Documentation reflects configuration changes. ## Files to Prioritize - `.env.example` - `docker-compose.yml` - `docker-compose.dev.yml` - `frontend/vite.config.ts` - Relevant package scripts and startup files ## Anti-Patterns - Hidden required env vars with no defaults. - Inconsistent host/port/proxy settings across environments. - Config changes without doc updates. ## Response Format Report: - Config files reviewed - Compatibility impact (none/low/high) - Required follow-up updates - Final readiness recommendation --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/danielvolz) — claim your Tome and manage your conversions.
