## What This Means
Your Claude session ended while using a significant amount of context. This could mean:
1. You were working on a complex task
2. Context limits were approaching
3. Session was interrupted
## Recovery Steps
### 1. Check Your Progress
Review these recently modified files:
`;

### 2. Review Last Actions
Recent commands executed:

for (const cmdInfo of recentCommands) {
recoveryContent += `- \`${cmdInfo.command}\`\n`;
}

### 3. Continue Your Work
1. Check \`ACTIVE_TODOS.md\` for pending tasks
2. Review \`LAST_SESSION.md\` for complete session history
3. Use \`git status\` to see current file changes
4. Consider committing your progress: \`git add -A && git commit -m "Work in progress"\`
### 4. Available Backups

## Context Status
- **Context Usage**: {context_usage:.1%} when session ended
- **Reason**: Session ended with high context usage
## What This Means
Your Claude session ended while using a significant amount of context. This could mean:
1. You were working on a complex task
2. Context limits were approaching
3. Session was interrupted
## Recovery Steps
### 1. Check Your Progress
Review these recently modified files:
"""
for file_path in session_summary.get('modified_files', []):
recovery_content += f"- {file_path}\n"
recovery_content += f"""
### 2. Review Last Actions
Recent commands executed:
"""
recent_commands = session_summary.get('commands_executed', [])[-5:]
for cmd_info in recent_commands:
recovery_content += f"- `{cmd_info['command']}`\n"
recovery_content += f"""
### 3. Continue Your Work
1. Check `ACTIVE_TODOS.md` for pending tasks
2. Review `LAST_SESSION.md` for complete session history
3. Use `git status` to see current file changes
4. Consider committing your progress: `git add -A && git commit -m "Work in progress"`
### 4. Available Backups
"""
for backup in session_summary.get('backup_history', []):
status = "" if backup['success'] else ""
recovery_content += f"- {status} {backup['backup_id']} - {backup['reason']}\n"
recovery_content += f"""
## Quick Recovery Commands
```bash
# Check current status
git status
# View recent changes
git diff
# List available backups
ls .claude_hooks/backups/
# View active todos
cat ACTIVE_TODOS.md
# View last session summary
cat LAST_SESSION.md
```
*This recovery guide was created because your session ended with {context_usage:.1%} context usage.*
