Sol utility
Run the review or rewrite task on gpt-5.6-sol with the Codex CLI:
codex exec -m gpt-5.6-sol -s read-only --skip-git-repo-check --ephemeral -C . "<task>"
For rewriting a loop prompt, feed the current prompt.md plus log.md to Sol
with the rewriter instructions from the self-improving loop, and give
workspace-write so it can rewrite prompt.md in place. Rewrites stay at most
20% larger than the original.
