Codex Debugging

Use when investigating Codex CLI/app behavior, config parsing, tool behavior, prompts, MCP/app wiring, or runtime bugs.

Source First

Prefer local source before web/docs:

cd ~/Projects/codex
sed -n '1,220p' codex-rs/AGENTS.md

Then search targeted areas:

rg "<symbol|setting|error|feature>" codex-rs/{core,tui,exec,cli,app-server,app-server-protocol,config}
