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.
