## Changes

### Major Features

Agent Management System (New!)

- **New `/agents` command**: Create and manage custom subagents that Claude can delegate tasks to
- Create agents with specialized system prompts and tool access
- Choose between AI-generated or manual agent configuration
- Agents can be stored at project level (`.claude/agents/`) or personal level (`~/.claude/agents/`)
- Built-in agents are always available and cannot be modified
- Each agent can have a custom background color for visual distinction

**Example usage:**

`# Open the agent management interface
/agents`
Background Shell Management Tools (New!)

- **KillShell Tool**: Kill a running background shell by its ID
- Use `/bashes` command to find shell IDs
- Returns success/failure status

- **BashOutput Tool**: Retrieve output from background shells
- Returns only new output since last check
- Shows stdout, stderr, and shell status
- Automatically truncates very long outputs

### Enhanced Features

Bash Output Summarization

- Claude now intelligently summarizes verbose command outputs
- Summaries are triggered for outputs over 5000 characters
- Original output is preserved and can be viewed in verbose mode
- Includes sections for: Overview, Detailed Summary, Errors, and Verbatim Output
- Particularly useful for build logs, test results, and repetitive debug output

**Example scenario:**

`# Running a command with verbose output
npm run build

# Claude will automatically summarize if output is lengthy, showing:
[Summarized output]
Overview: Build completed successfully...
Detailed summary: ...
Errors: None encountered
Verbatim output: [key snippets preserved]`
Spinner Tips

- Tips functionality has been made configurable
- Tips are now fetched dynamically based on user preferences
- Improved tip management system

### UI/UX Improvements

Enhanced Dialog Components

- New `bv1` component for better dialog presentation
- Improved escape key handling with "Press Esc again to exit" confirmation
- Consistent styling with rounded borders and proper spacing

OAuth Flow Improvements

- Added manual code entry support for OAuth authentication
- Better error handling with retry options
- Visual improvements during the authentication process
- Support for long-lived tokens (1 year expiry) for GitHub Actions

### Technical Improvements

️ Command System Enhancements

- New agent type system with built-in types:
- `general-purpose`: General multi-step task handling
- `context-collector`: Codebase exploration and metrics
- `tech-researcher`: Technical solution research
- `test-engineer`: Test writing and maintenance
- `spec-designer`: Specification refinement
- `file-organizer`: File operations and organization
- `comment-writer`: Code documentation
- `investigator`: Deep code investigation
- `refactoring-specialist`: Code improvement
- `code-auditor`: Architecture and security analysis
- `implementation-engineer`: Feature implementation
- `documentation-specialist`: Comprehensive documentation
- `style-fixer`: Code formatting and style

Aliases and Usability

- `/clear` command now also responds to `/reset` alias
- Improved permission handling for additional working directories
- Better path resolution and validation

### Developer Experience

Agent Creation Workflow

- **Choose location**: Project or personal agents directory
- **Creation method**: AI-generated or manual configuration
- **Define purpose**: Describe what the agent should do
- **Select tools**: Choose which tools the agent can access
- **Customize appearance**: Optional background color
- **Review and save**: Confirm configuration before saving

**Example agent creation:**

`/agents
# Select "Create new agent"
# Choose location: Project
# Method: Generate with Claude
# Describe: "Expert code reviewer that checks for security vulnerabilities and best practices"
# Claude generates the configuration
# Select tools the agent should have access to
# Choose a background color
# Save the agent`

### Bug Fixes and Cleanup

- Removed unused OAuth error classes and related error handling code
- Cleaned up shell snapshot cleanup functionality
- Removed various deprecated functions and imports
- Fixed issue with pasted text display (now shows "[Pasted text #X]" without "+0 lines")

### Breaking Changes

- None identified in this release

### Notes for Users

- Agents provide a powerful way to create specialized assistants for specific tasks
- Background shell management allows better handling of long-running processes
- Output summarization helps maintain context efficiency while preserving important information
- The new agent system is particularly useful for repetitive tasks like code reviews, testing, and documentation
