If you've run `trellis init` and need to customize the generated `.trellis/` directory, workflow phases, task hooks, or platform-specific settings, this is the skill that teaches Claude how all those pieces fit together. It walks through the three-layer architecture, explains where to put project conventions versus modify agent behavior, and covers the actual customization entry points in your local files. The references are organized by concern: local architecture, platform file mapping, and specific customization guides for workflows, tasks, specs, and hooks. One thing to know upfront is that it's very explicit about not treating the upstream Trellis source or node_modules as customization targets, everything stays in your project's local files.
