Chester Ismay, a data science educator and AI consultant, created schedule viewers to keep up with the sports he follows, including the WNBA, NFL, NBA, and Premier League. But he still had to decide which games deserved his attention each week.
In this episode of Zero to Agent in 30 Minutes, Chester built a sports concierge agent to surface the games he should watch. It reads his preferences and current schedules, then sends a weekly summary to his phone. He took the audience through the setup, which combines a prompt file, limited tool permissions, a schedule, and notifications.
How to create your own sports concierge
- Define your preferences. Chester started with a structured preferences file that identifies the teams he follows and adds context about why he follows them. He built a simple web interface for editing those preferences rather than working directly with the underlying JSON.
- Give the agent access to current schedule data. His existing sports viewers pull schedule information from sources such as ESPN and store it in repositories on GitHub. A read-schedules tool, run with Node, pulls the latest schedule files and combines them with Chester’s preferences, giving the agent the information it needs without requiring it to search for each game on its own.
- Write the agent’s policy. Chester spent most of the walkthrough on CONCIERGE.md, the file that defines the agent’s job. The policy sets the goal, identifies the data sources, and defines the rules for deciding which games to recommend. It also specifies how to handle finished tournaments and duplicate matchups, along with the expected output and delivery format. Chester noted that when the output misses the mark, he goes back to the policy and adds more detail to the instructions or adjusts them to better match with the goals of the project.
- Run the agent with limited permissions. Chester used Claude Code to read the files, apply the policy, and generate the weekly recommendations. He configured permissions so the agent worked only with the files and tools required for the task.
- Schedule delivery and check the results. Chester used launchd on his Mac to run the concierge every Wednesday and ntfy to send the result to his phone. He checks the recommendations against the underlying schedules and uses tests and multiple data sources to catch errors. Time zone handling required another adjustment. Games could fall on the wrong day when the system defaulted to UTC, so Chester added explicit time zone instructions.

Next week, AI engineer Sajal Sharma gives an agent its own computer in the cloud using services such as E2B and Scrapybara. He’ll demonstrate how sandboxing lets an agent install packages, run code, drive a browser, and control a remote desktop.
