Track training and nutrition habits with a health agent
The poster built an agent that uses two Sheets tools to track and analyze training and nutrition, with sleep and psychological tracking planned. ·
Done with a custom-built or unnamed agent
- What they did
- The poster said they spent five months building one main agent to manage two Google Sheets-style tools: one for training and one for nutrition. The current interface is WhatsApp messages received by API, and a “get rows” step runs before the agent so data is filtered or recorded for the user who sent the message; for broader analysis, they planned an n8n AI agent node with access to the user’s vectorized data.
- How it went
- It was still in development: the poster said tracking was not finished, and psychological and sleep tracking plus a combined body score were still planned. No usage numbers or measured results were given.
- Worth knowing
- The main practical catch mentioned is privacy and validation: they rely on a pre-agent “get rows” filter tied to the message sender before the agent sees spreadsheet data.
Try it yourself with Claude Code
Build me a health tracking agent that reads and writes two Google Sheets: one for training ([sheet link]) and one for nutrition ([sheet link]). It should log entries from my plain-language messages, then give me a weekly analysis of trends against my goal of [goal]. Keep it structured so I can add sleep and mood tracking later, and show me any changes to the sheets' structure before applying them.
