| 1 | # Editor Plugin DOX |
| 2 | |
| 3 | ## Purpose |
| 4 | |
| 5 | - Own the native Markdown and plain text editor surface for canvas and floating modal workflows. |
| 6 | |
| 7 | ## Ownership |
| 8 | |
| 9 | - `api/` owns editor session and WebSocket handlers. |
| 10 | - `helpers/` owns editor text session and open-file context helpers. |
| 11 | - `prompts/` owns agent-visible open-file context. |
| 12 | - `webui/` owns editor panel, preview, store, and main surface. |
| 13 | - `extensions/` owns editor hook contributions. |
| 14 | |
| 15 | ## Local Contracts |
| 16 | |
| 17 | - Keep editor session state synchronized across API, WebSocket, and WebUI panel behavior. |
| 18 | - Do not expose unsaved content or local paths beyond intended chat/context surfaces. |
| 19 | - Keep the floating Editor modal on the shared surface modal chrome so the header remains draggable while existing Focus mode continues to work. |
| 20 | - Keep Editor Open wired through the File Browser text picker so users can open one or more Markdown or plain text files with an obvious confirmation action. |
| 21 | - Keep Download in the Editor file-actions menu and save dirty text before downloading it. |
| 22 | - Keep Save As distinct from Rename: Save As writes the current editor text to a chosen `.md` or `.txt` path and retargets the active session without removing the original file. |
| 23 | - Keep Markdown and plain text on the same toolbar, with full-document source and preview modes plus shared Undo/Redo buttons and keyboard shortcuts. |
| 24 | - Preserve source chat context ids when opening Markdown files from tool-result canvas handoffs. |
| 25 | |
| 26 | ## Work Guidance |
| 27 | |
| 28 | - Coordinate editor preview and session changes with canvas surface registration. |
| 29 | |
| 30 | ## Verification |
| 31 | |
| 32 | - Smoke-test opening, editing, previewing, and reconnecting editor sessions after changes. |
