Build and publish a BaZi chart reading agent
A published walkthrough shows the developer used AI coding agents to build the full stack solo. The agent received a deterministic BaZi calendar engine to compute exact charts from birth data powered by solar terms, stem-branch calendar and 10-year luck cycles, then interpreted results while auto-detecting language for output plus chart image. It went live on the OKX AI Marketplace as Agent #4939 and settled over 20 real transactions.

Why it matters
Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 106 sightings filed under Software Development on Agent Sightings (number 43 by interest), and one of 32 involving Codex.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Codex or any similar agent and adjust the details to your situation.
In this repo, build and publish a BaZi chart reading agent. Read relevant code, apply a minimal patch, run available checks, and summarize the diff. Stop before merge or deploy.
The prompt breaks down into 3 steps you can check as the agent works:
- In this repo, build and publish a BaZi chart reading agent.
- Read relevant code, apply a minimal patch, run available checks, and summarize the diff.
- Stop before merge or deploy.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
