Codex Refactor

Use Codex CLI to analyze code and apply a refactor.

1) Build the prompt

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

• The target (file, module, pattern, or concept to refactor)
• The goal (simplify, extract, decouple, rename, restructure, etc.)
• Any constraints (preserve API, maintain backwards compat, etc.)

2) Run Codex

Log output to a tmp directory:

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

3) Follow response contract

Structure the response as:

• Current state — what the code looks like now and why it's problematic
• Changes applied — what was changed, with file paths and line references
• Trade-offs — what improves, what gets more complex, what might break

After Codex finishes, review the changes and run tests to verify nothing broke.
