# LikeC4 DSL Skill Architecture-as-code tool. Describe systems in `.c4`/`.likec4` files and LikeC4 generates interactive diagrams. ## Rules 1. **Projects** - it is possible to have multiple likec4 projects in a workspace, project is determined by presence of a config file (`.likec4rc`, `likec4.config.{ts,js,json}`). LikeC4 files belong to the project of the nearest config file in the directory hierarchy. 2. **Top-level statements** — only `import`, `specification`, `model`, `deployment`, `views`, `global` are allowed. Blocks can repeat, but at least one per file must be present. 3. **Multi-file merge** — Top-level blocks across files are merged. For example, `model { ... }` blocks present in multiple files, parsed separately, and then merged into a single model. 4. **Strings** — `'single'`, `"double"` — all support multi-line. Escape quotes with backslash: `\'` or `\"`. 5. **Markdown** — properties like `summary`/`description`/`notes` can contain Markdown. Use triple quotes `'''` or `"""`. Begin a new line after opening quotes and indent Markdown content for better formatting and syntax highlighting. 6. **Comments** — `// single line` and `/* multi-line */` comments supported anywhere. 7. **Identifier** — letters, digits, hyphens, underscores only. No dots (dots are FQN separators). Can't start with a digit. Examples: `customer`, `payment-service`, `frontendApp`, `queue-1`. **Critical:** `payment-api` is valid; `payment.api` is NOT an identifier (dots separate FQN hierarch
