# VidFlow > Context for Claude/Codex is maintained in Obsidian Mind: > ~/my-vault/work/projects/vidflow.md > Run `/om-project-switch` from the vault to load full context. ## Operational Rules - Single-file project — everything lives in `vidflow.html` - No build step, no framework, no external dependencies - Local dev: `python3 -m http.server 8080` (must be HTTP, not file://) - Never hardcode API keys
