description	Use this when updating the codex submodule or when patch files in codex-patches/ need to be added, regenerated, or repaired.

Codex Patch Workflow

Use this skill whenever you touch the codex submodule (codex/) or the patch series in codex-patches/.

Apply Patches After Submodule Update

1. Update the codex submodule to the target commit:

cd codex
git checkout <commit>
cd ..

2. Apply our patches:

scripts/apply_codex_patches.sh

If a patch fails, fix only that patch before moving on.

Repairing a Broken Patch

General approach:

1. Rehydrate codex/ to clean upstream before re‑diffing:

git archive codex-upstream/main | tar -x -C codex

2. Re‑apply the remaining patches that still work. Fix conflicts manually if needed.
3. Regenerate the broken patch by diffing the upstream file(s) against our modified version.

Regenerating a Patch (stable diff style)

Prefer diffs against the upstream tree to reduce context drift. For the full example script, see references/regen_patch_example.md.

Patch Hygiene

• Keep each patch focused on a single feature or concern.
• Avoid bundling unrelated changes into the same patch.
• Do not include upstream-only changes; patches should be fork-only deltas.

Quick Smoke Test

After applying patches, run:
