The article outlines a method for generating a daily summary of Claude Code activity. It emphasizes the importance of tracking token usage and tasks accomplished for effective project management. The process begins with a command (`npx ccusage --today`) to obtain accurate token counts, followed by a script that extracts user prompts from the day's activity, grouped by project. The script uses timestamps to capture all relevant prompts and filters them based on specific criteria, ensuring only meaningful entries are included. Once data is collected, the article guides the user to analyze the prompts and categorize them into significant work themes. Each theme should reflect substantial efforts, defined as tasks that took at least 10-15 minutes to complete. For each theme, users are encouraged to note key decisions made, artifacts produced, and the nature of the work. The focus is on summarizing the day's accomplishments without getting bogged down in minor tasks. The article provides a structured markdown format for recording daily activity. It includes sections for token usage, an overall day summary, and specific themes. This format promotes clarity and helps users quickly grasp what was achieved throughout the day. Emphasis is placed on grouping work by theme rather than project, capturing the essence of the day’s productivity while discarding minor details that don't contribute to the larger picture. Overall, the approach advocates for a disciplined method of reflecting on daily work that balances detail with brevity. It aims to foster a better understanding of productivity patterns and guide future efforts based on past activities.
