description	Skill for resolving .lycheecache merge or rebase conflicts in the current branch or a specified PR.
argument-hint	[optional-pr-number]

.lycheecache is an auto-generated file. Resolving conflicts requires first taking the integration branch's side, finishing the merge/rebase, then running npm run fix:refcache to restore any URLs unique to the active branch.

Prerequisites

If the current branch has a merge or rebase in progress, then skip the rest of this section and jump to Preparation.

The current branch must be clean (git status --short). If not clean, offer to run git stash or git commit to clean it up, or stop.

If $ARGUMENTS is a PR number, then check out the PR branch with: gh pr checkout $ARGUMENTS.

Preparation

At this point, we are ready to resolve the conflicts in the active branch:

1. Determine the integration reference ($BASE_BRANCH) and fetch it:

   • If an upstream remote exists: git fetch upstream, use upstream/main.
   • Otherwise: git fetch origin, use origin/main.

2. If merge or rebase is in progress (git status), skip this step. Otherwise, ask the user whether to run git merge $BASE_BRANCH or git rebase $BASE_BRANCH, then run it.

3. If there are no conflicts: stop, we are done.

4. Conflicts other than .lycheecache: resolve them with the user.

5. If no .lycheecache conflict remains: stop, we are done. Otherwise, proceed to Resolve.

Resolve

1. Check out the $BASE_BRANCH version of .lycheecache. Assumes the active branch is being rebased/merged from $BASE_BRANCH, not the other way around:

   Operation	Command
   Rebase of active branch onto $BASE_BRANCH	git checkout --ours .lycheecache
   Merge of $BASE_BRANCH into active branch	git checkout --theirs .lycheecache

2. Stage the resolved files, then continue:

   • Rebase: git add .lycheecache && git rebase --continue
   • Merge: git add .lycheecache && git commit --no-edit
   • If other files were resolved in Preparation step 4, git add those too before continuing.

3. Rebase only: for each subsequent rebase stop that conflicts on .lycheecache, repeat Resolve steps 1–2. If other paths are also conflicted on that stop, run Preparation step 4 first.

4. Run npm run fix:refcache once, after the entire rebase/merge completes. Note: this runs a Hugo build (lean by default) and link check — requires network, installed npm dependencies, and populated submodules; can take several minutes.

5. Commit the changes, if any:

   git add .lycheecache
   git diff --cached --quiet .lycheecache || \
      git commit -m "Refresh refcache after resolving conflicts"
   

6. Push:

   • Merge: git push
   • Rebase: git push --force-with-lease
