The default toolbox. New tools are added deliberately, project by project, as a way to learn. When a project introduces something outside this list, record the choice and the reason in that project's README; if it becomes a recurring habit, add or extend a rule file here.
| Layer | Default |
|---|---|
| Backend | Go, Python |
| Database | PostgreSQL |
| Cache / queue | Redis |
| Frontend | Vue.js |
| Packaging | Docker |
Per-language and per-tool conventions live in their own rule files: go.md, python.md, vue.md, docker.md, data.md.
