+# Resolve Merge Conflicts
+
+Use this skill when merging `origin/main` into a branch, especially when the
+only conflicts are generated `.github/workflows/*.lock.yml` files.
+
+## One-step path
+
+From the repository root, run:
+
+```bash
+./.github/skills/resolve-merge-conflicts/resolve.sh origin/main
+```
+
+The command works both before a merge and after another command has stopped on
+conflicts. It:
+
+1. Starts the merge with `--no-commit`, or resumes the current merge.
+2. Refuses to auto-resolve if any conflict is not a workflow `.lock.yml`.
+3. Runs `make recompile` once so generated files come from the merged Markdown.
+4. Stages the regenerated conflicting lock files.
+5. Verifies that no unresolved paths or whitespace errors remain.
+
+The script does not fetch, commit, push, abort, or edit workflow Markdown.
+Refresh `origin/main` first only when credentials are available. After success,
+review the staged merge, run the repository's final validation gate, then
+commit and push.
+
+## Safety rules
+
+- Never choose `ours` or `theirs` for compiled lock files; regenerate them.
+- Never manually remove conflict markers from `.lock.yml` files.
+- Never auto-resolve a source `.md`, Go, JavaScript, or other mixed conflict.
+- If the script refuses a mixed conflict, resolve source conflicts on their
+  merits, stage them, and rerun the same command. It will regenerate the
+  remaining lock conflicts.
+- Do not abort an existing merge unless the user explicitly requests it.
