+ask — An agent that can read files, see images, search the internet, and answer questions.
+
+Usage:
+  ask --prompt-file FILE [-i IMAGE]
+
+Options:
+  --prompt-file FILE   Path to file containing the prompt (required).
+  -i IMAGE             Attach an image file to the prompt.
+  -h, --help           Show this help and exit.
+
+Behavior:
+  - Isolates from ~/.codex by using a temp CODEX_HOME (unless CODEX_HOME is set).
+  - Copies only ~/.codex/auth.json into that temp home (no AGENTS.md).
+  - Prints the agent's last message to stdout.
+
+Exit codes:
+  0 success; 1 codex error; 2 usage error; 127 codex not found.
+
+Examples:
+  ask --prompt-file prompt.txt
+  ask --prompt-file prompt.txt -i image.png
