What it does

You get a clean timesheet in Google Sheets every day at 7 PM by automatically pulling your emails, calendar events, and GitHub activity. The agent filters out noise like newsletters or irrelevant commits before using an AI to summarize each item for easy billing and reporting.

LLM

OpenAI : Generating concise activity summaries

Watch out for

LLM token costs can accumulate quickly with large volumes of emails, so limit the input text length before sending it to the model.
GitHub API rate limits may block commits if many repositories are queried simultaneously, so add a delay node between requests.
Google Sheets writes can fail silently if the sheet permissions are incorrect, so verify service account access rights beforehand.
Duplicate entries might appear if the workflow runs twice before data is marked as processed, so implement an ID check in the code node.
