- Add generateDiffString() function in edit tool to create unified diffs with line numbers and 4 lines of context
- Store only the formatted diff string in tool result details instead of full file contents
- Update tool-execution renderer to parse and colorize the diff string
- Filter out message_update events from session saving to prevent verbose session files
- Add markdown nested list and table rendering tests
**Improved output messages:**
1. File fits within limits: Just outputs content (no notices)
2. Lines get truncated: Shows "Some lines were truncated to 2000 characters for display"
3. File doesn't fit limit: Shows "N more lines not shown. Use offset=X to continue reading"
4. Offset beyond file: Shows "Error: Offset X is beyond end of file (N lines total)"
5. Both truncations: Combines both notices with ". " separator
**Comprehensive test coverage:**
- Files within limits (no notices)
- Large files (line truncation)
- Long lines (character truncation)
- Offset parameter
- Limit parameter
- Offset + limit together
- Invalid offset (out of bounds)
- Combined truncations (both notices)
All 17 tests passing ✓
- Default limit of 2000 lines per read
- Maximum line length of 2000 characters (truncates longer lines)
- Add optional offset and limit parameters for pagination
- Show truncation notice with instruction to continue reading
- Plain text output (no line numbers)
Examples:
- `read path/to/file` - reads first 2000 lines
- `read path/to/file offset=2001` - continues from line 2001
- `read path/to/file limit=100` - reads only 100 lines
This prevents extremely large files from overwhelming context.
Tools now resolve with error messages in content blocks rather than
rejecting the promise. This matches the expected behavior where tools
always return a result, with errors indicated in the text content.
- read: Return error content for missing files
- edit: Return error content for missing files, text not found, multiple matches
- bash: Return error content for command failures, timeouts, and aborts
- All tools now include required details field in error results
Tool results now use content blocks and can include both text and images.
All providers (Anthropic, Google, OpenAI Completions, OpenAI Responses)
correctly pass images from tool results to LLMs.
- Update ToolResultMessage type to use content blocks
- Add placeholder text for image-only tool results in Google/Anthropic
- OpenAI providers send tool result + follow-up user message with images
- Fix Anthropic JSON parsing for empty tool arguments
- Add comprehensive tests for image-only and text+image tool results
- Update README with tool result content blocks API
Replace synchronous file operations with async Promise-based operations
that listen to abort signals during execution:
- read, write, edit now use fs/promises async APIs
- Add abort event listeners that reject immediately on abort
- Check abort status before and after each async operation
- Clean up event listeners properly
This ensures pressing Esc during file operations shows red error state.
All tools now check the abort signal before executing and throw
"Operation aborted" error if the signal is already aborted.
This ensures consistent abort behavior across all tools.
- Show tool execution components immediately when tool calls appear in streaming
- Update components with streaming arguments as they come in
- Handle incomplete/partial arguments gracefully with optional chaining
- Fix error handling: tools now throw exceptions instead of returning error messages
- Fix bash abort handling to properly reject on abort/timeout
- Clean up error display
- Remove "Command aborted by user" message (Aborted already shown separately)
- Remove STDOUT/STDERR labels - just show output cleanly
- Stderr is now separated by newline without labels
- Timeout and error messages moved to end of output
- Switch from exec() to spawn() with detached: true
- Create new process group for spawned commands
- Kill entire process group with process.kill(-pid) on abort
- This ensures commands like "sleep 4 && echo hello" abort immediately
- Previous implementation only killed parent shell, leaving subprocesses running
- Add /thinking slash command with autocomplete for setting reasoning levels (off, minimal, low, medium, high)
- Fix Ctrl+C behavior: remove hardcoded exit in TUI, let focused component handle it
- Add empty lines before and after tool execution components for better visual separation
- Fix stats rendering: display stats AFTER tool executions complete (matches web-ui behavior)
- Remove "Press Ctrl+C again to exit" message, show "(esc to interrupt)" in loader instead
- Add bash tool abort signal support with immediate SIGKILL on interrupt
- Make Text and Markdown components return empty arrays when no actual text content
- Add setCustomBgRgb() method to Markdown for dynamic background colors
