Codex Fix

Use Codex CLI to independently diagnose and fix a bug.

1) Build the prompt

From the user's request, construct a prompt for Codex that includes:

• •The symptom (error message, unexpected behavior, failing test)
• •Relevant file paths or function names if known
• •Any context about what was tried already

2) Run Codex

Log output to a tmp directory:

CODEX_DIR="$(mktemp -d)/codex-fix"
mkdir -p "$CODEX_DIR"
codex --sandbox danger-full-access -a never exec "$PROMPT" | tee "$CODEX_DIR/fix.log"

3) Follow response contract

Structure the response as:

• •Root cause — what's actually wrong and why
• •Fix applied — what was changed, with file paths and line references
• •Risk — anything the fix might break or leave unaddressed

After Codex finishes, review the changes and run tests to verify the fix.
