How to automate a Daily Report with an AI agent

Run your agent headless on a schedule. Use claude -p or codex exec from cron, or set up a scheduled Cursor Automation. Write the prompt once, limit the tools it may use, and have it save the report to a file or send it to you for review rather than straight to other people.

Claude Code

Test the prompt: claude -p "Read data/sales.csv and write a 5 line summary to reports/today.md" --allowedTools "Read,Write"
Add it to cron: 0 8 * * * cd ~/reports && claude -p "..." --allowedTools "Read,Write"
Add --bare to skip hooks, plugins and MCP discovery when you want faster, repeatable runs

Codex

Test: codex exec "summarize data/sales.csv into reports/today.md"
Schedule the same command with cron or your CI
See the codex exec reference for sandbox and approval flags

Cursor

Install the CLI: curl https://cursor.com/install -fsS | bash
Test: agent -p "summarize data/sales.csv" --output-format text
Or create a Cursor Automation with a schedule trigger

Grok Bot

Ask Grok Bot to run the report every weekday morning
It sets up a routine and sends you the result
Change or stop it by asking

Gotchas

cron runs with a bare PATH. Use full paths to claude, codex or agent.
Headless runs skip approval prompts, so restrict tools tightly.
Each run costs tokens. A daily report on a big file adds up.
