## Overview

All 40 issues identified in the PR review have been successfully fixed. The
codebase now builds cleanly and all tests pass (1384 tests in main package, 781
tests in web package).

## Fixes Completed

### Priority 1: Critical Bugs ✅

1. **Agent Hang on Denied Tools** - Fixed by properly handling denied
   ToolResults in agent.ts
2. **Race Condition in Environment Variables** - Fixed by passing environment
   through context instead of mutating global process.env

### Priority 2: Type Safety ✅

3. **Removed all 'any' types** - Updated to use proper TypeScript types with
   z.infer
4. **Fixed missing AbortSignal** - Added required signal field to all
   ToolContext instances

### Priority 3: UI Status Handling ✅

5. **Updated all UI components** - Added proper handling for 'aborted' and
   'denied' statuses
6. **Fixed isError logic** - Now properly distinguishes between errors
   ('failed', 'denied') and warnings ('aborted')
7. **Added status configurations** - All UI components now have proper
   color/icon mappings

### Priority 4: Abort Signal Propagation ✅

8. **All tools now propagate abort signals** - Added signal passing to execFile,
   fetch, and recursive operations
9. **Fixed memory leaks** - All abort event listeners are properly cleaned up
10. **Fixed process handling** - Null exitCode now properly handled in bash tool

### Priority 5: Error Handling ✅

11. **Tools return ToolResults** - No more throwing errors; all failures return
    proper ToolResults
12. **Sensitive header redaction** - Authorization and Cookie headers are now
    redacted in error messages
13. **Fixed encoding bug** - Changed 'utf-8' to 'utf8' in file-write tool

### Priority 6: Test Coverage ✅

14. **Added comprehensive test coverage** - New tests for abort scenarios,
    status handling, and edge cases
15. **Fixed test issues** - Updated status values, renamed tests for clarity,
    fixed argument order

### Priority 7: Other Fixes ✅

16. **Fixed regex escaping** - Added literal search option to ripgrep tool
17. **Fixed OpenAI format** - Tool results without IDs are now filtered out

## Test Results

- **Main Package**: 1384 tests passed, 22 skipped
- **Web Package**: 781 tests passed, 1 skipped
- **Build**: Successfully compiles with TypeScript strict mode
- **Linting**: All ESLint rules pass

## Key Architectural Improvements

1. **Event-Driven Consistency**: All tools properly return ToolResults through
   the event system
2. **Resource Management**: Proper cleanup of all resources on cancellation
3. **Type Safety**: Eliminated all uses of 'any' type
4. **Security**: Sensitive information is properly redacted
5. **UI/UX**: Clear visual distinction between errors, warnings, and success
   states

## Breaking Changes

None - all fixes maintain backward compatibility with the existing API.

## Files Modified

- 50+ source files across both main and web packages
- Comprehensive updates to tool implementations
- UI component updates for status handling
- Test file updates for coverage

## Next Steps

1. Review the three discussion items in review-repair.md:
   - Regex vs literal search default in ripgrep
   - Status precedence for deduplication
   - UI treatment of 'aborted' status
2. Push changes and update PR
3. Wait for reviewer feedback
