| description | Resolve merge conflicts in an open pull request for this repository. Use when the user says "/resolve-pr-conflicts", asks to fix PR conflicts, says a pull request cannot merge because it is behind main, asks to update a PR branch from main, or asks to make a conflicted PR testable again. |
/resolve-pr-conflicts
Overview
Resolve pull request merge conflicts without merging into main. Work on the
PR branch or a maintainer-owned conflict-fix branch, commit the resolved files,
push the branch, and leave the PR open for user testing.
Workflow
1. Identify the PR
Use the PR number or URL if the user provides one. Otherwise inspect open PRs
and choose the newest conflicted PR, clearly saying that assumption.
Prefer GitHub connector tools when available. Otherwise use gh:
gh pr list --state open --limit 20 \
--json number,title,author,headRefName,headRepositoryOwner,baseRefName,mergeStateStatus,isCrossRepository,url,updatedAt
gh pr view <number> \
--json number,title,body,author,headRefName,headRepositoryOwner,baseRefName,mergeStateStatus,isCrossRepository,maintainerCanModify,url,files,statusCheckRollup
Record the PR URL, base branch, source branch, whether the PR is from a fork,
whether maintainers can modify it, and the current check state.
2. Protect Local Work
Check the current checkout before changing branches:
git status --short --branch
git worktree list
Do not overwrite or revert unrelated local changes. Prefer a new worktree for
conflict work, especially when the main checkout has local files.
Use a worktree from the PR branch when it can be pushed:
git fetch origin <base-branch>
gh pr checkout <number> --branch <local-pr-branch>
git worktree add ../<repo>-pr-<number>-conflicts <local-pr-branch>
If the PR comes from a fork and cannot be pushed safely, create a same-repo
branch from the PR head instead and tell the user the original PR may need a
replacement PR:
gh pr checkout <number> --detach
git switch -c <maintainer-conflict-branch>
3. Bring in the Base Branch
Fetch the latest base branch and merge it into the PR branch. Do not merge the
PR into main.
git fetch origin <base-branch>
git merge origin/<base-branch>
If the repository convention prefers rebase and the PR has not been shared or
reviewed, rebase is acceptable. For existing shared PRs, prefer merge because it
does not rewrite the contributor's history.
4. Resolve Conflicts Deliberately
List conflicted files:
git status --short
git diff --name-only --diff-filter=U
For each file:
- Read both sides of the conflict and the surrounding current code.
- Keep the intended PR behavior while preserving newer changes from the base
branch.
- Remove all conflict markers:
<<<<<<<, =======, >>>>>>>.
- Avoid broad formatting or unrelated cleanup while resolving conflicts.
- Regenerate derived files only when the repository has an established generator
for the affected output.
Use structured tools for structured formats where practical:
- YAML: preserve indentation, anchors, substitutions, and comments.
- JSON/package lock files: prefer the package manager or lockfile-aware tooling.
- Generated firmware, manifests, icons, or docs output: run the matching
generator/check command instead of hand-editing large generated sections.
When the right resolution is unclear, inspect the original PR diff and recent
base-branch changes:
gh pr diff <number> --patch
git log --oneline --decorate -- <file>
git diff ORIG_HEAD...HEAD -- <file>
5. Run Focused Checks
Run checks that match the files touched by the conflict. Common commands in this
repository include:
npm run check:config
python3 scripts/build.py --check
python3 scripts/generate_device_slots.py --check
python3 scripts/check_icon_groups.py
python3 scripts/check_timezones.py
npm run docs:build
Use the repo-local compile skill when firmware YAML, common YAML, device YAML,
or C++ component changes need compile-level confidence.
If a check cannot be run locally, say why and name what remains unverified.
6. Commit and Push
Confirm only intended files changed:
git status --short
git diff --check
git diff --stat
Commit the conflict resolution with a plain message:
git add <resolved-files>
git commit -m "Resolve PR <number> merge conflicts"
git push
If working on a newly created same-repo branch, push with upstream and open a
draft PR into the original base branch, explaining that it carries the original
PR plus conflict resolutions.
Do not merge the PR, close linked issues, or mark device testing complete unless
the user explicitly confirms the tested result.
Output Format
Keep the final update approachable and practical:
Resolved conflicts for PR #<number>: <title>
What changed:
- <plain-English summary of the conflict resolution>
Checks run:
- <command>: <pass/fail/skipped and why>
Pushed:
- <branch or PR URL>
What to test:
- <device/display or workflow the user should test before merge>
