- Changed ToolRenderer return type from TemplateResult to ToolRenderResult
- ToolRenderResult = { content: TemplateResult, isCustom: boolean }
- isCustom: true = no card wrapper, false = wrap in card
- Updated all existing tool renderers to return new format
- Updated Messages.ts to handle custom rendering
This enables tools to render without default card chrome when needed.
Console Logging Improvements:
- Changed ConsoleRuntimeProvider to send logs immediately instead of batching
- Track pending send promises and await them in onCompleted callback
- Ensures REPL gets all logs before execution-complete
- Enables real-time console logging for HTML artifacts
Message Routing Fixes:
- Remove "handled" concept from message routing - broadcast all messages to all providers/consumers
- Change handleMessage return type from Promise<boolean> to Promise<void>
- Add debug logging to RuntimeMessageRouter to trace message flow
- Fix duplicate error logging (window error handler now only tracks errors, doesn't log them)
Output Formatting Consistency:
- Remove [LOG], [ERROR] prefixes from console output in both tools
- Show console logs before error messages
- Use "=> value" format for return values in both javascript-repl and browser-javascript
- Remove duplicate "Error:" prefix and extra formatting
Bug Fixes:
- Fix race condition where execution-complete arrived before console logs
- Fix ConsoleRuntimeProvider blocking execution-complete from reaching consumers
- Remove duplicate console log collection from SandboxedIframe
- Fix return value capture by wrapping user code in async function
- Router was stopping propagation after first handler returned true
- This prevented consumers from seeing messages that providers handled
- executionConsumer never received execution-complete because ConsoleRuntimeProvider handled it first
- Now all providers and consumers receive all messages
- Fixes javascript_repl never completing
Major refactoring to unify runtime providers across sandbox and user script contexts:
1. Runtime Bridge & Router
- Add RuntimeMessageBridge for unified messaging abstraction
- Rename SandboxMessageRouter → RuntimeMessageRouter
- Router now handles both iframe and user script messages
- Guard for non-extension environments
2. Provider Refactoring
- ArtifactsRuntimeProvider: Add offline mode with snapshot fallback
- AttachmentsRuntimeProvider: Remove returnDownloadableFile (moved to dedicated provider)
- ConsoleRuntimeProvider: Add message collection, remove lifecycle logic
- FileDownloadRuntimeProvider: New provider for file downloads
3. HTML Escaping Fix
- Escape </script> in JSON.stringify output to prevent premature tag closure
- Applies when injecting provider data into <script> tags
- JavaScript engine automatically unescapes, no runtime changes needed
4. Function Renaming
- listFiles → listAttachments
- readTextFile → readTextAttachment
- readBinaryFile → readBinaryAttachment
- returnFile → returnDownloadableFile
5. Updated Exports
- Export new RuntimeMessageBridge and RuntimeMessageRouter
- Export FileDownloadRuntimeProvider
- Update all cross-references
This sets the foundation for reusing providers in browser-javascript tool.
