Fix Plan

To address the issue of context window usage showing 0 or unknown despite extensive conversation, we need to modify the way context statistics are tracked and displayed.

Step-by-Step Solution:

1. Update OpenClaw Configuration: Ensure that the contextWindow and maxTokens are correctly set in ~/.openclaw/openclaw.json. For example:

   {
     "contextWindow": 1000000,
     "maxTokens": 131072
   }

2. Modify Context Tracking: Update the code to count both user input and agent output towards the context statistics. This might involve modifying the session_status and openclaw status commands to accurately reflect the total tokens used.
3. Handle File Content: Adjust the handling of file content to include it in the context statistics. This could involve adding the file size (in tokens) to the total context usage when a file is processed.
4. Prevent Statistics Reset: Ensure that context statistics are not reset after a Gateway restart. This might involve storing the statistics in a persistent storage that survives restarts.

Example Code Snippet (Python):

def update_context_statistics(session_id, tokens_used):
    # Load current statistics
    stats = load_statistics(session_id)
    
    # Update statistics
    stats['context_usage'] += tokens_used
    
    # Save updated statistics
    save_statistics(session_id, stats)

def load_statistics(session_id):
    # Load from persistent storage
    # For simplicity, assume a dictionary stored in a file
    try:
        with open(f'{session_id}_stats.json', 'r') as file:
            return json.load(file)
    except FileNotFoundError:
        return {'context_usage': 0}

def save_statistics(session_id, stats):
    # Save to persistent storage
    with open(f'{session_id}_stats.json', 'w') as file:
        json.dump(stats, file)

Verification

To verify that the fix worked, follow these steps:

• Start a new conversation via Feishu direct message.
• Send a large file (> 1M) and have the agent process it.
• Generate a long summary.
• Make multiple tool calls.
• Run session_status or openclaw status to check the context usage.
• The output should now accurately reflect the total tokens used, including both user input and agent output, and should not reset after a Gateway restart.

Extra Tips

• Regularly review and update the contextWindow and maxTokens configurations to ensure they meet the needs of your conversations.
• Consider implementing a mechanism to alert users when the context usage approaches the maximum allowed, to prevent unexpected truncation of conversations.
• Ensure that all components involved in tracking and displaying context statistics are updated and compatible with each other to avoid version conflicts.
