.claude/skills/update-from-starter-template/# Update from Starter Template Update this Mattermost plugin repository with common build/config files from the [mattermost-plugin-starter-template](https://github.com/mattermost/mattermost-plugin-starter-template) and fix all linter issues. ## Instructions ### Phase 0: Prepare the repository 1. Switch to the main branch: `git checkout master` (or `main`) 2. Pull latest changes: `git pull` 3. Create a new branch for the updates: `git switch -c update-from-starter-template` ### Phase 1: Update common files from starter template Fetch and compare these files from `mattermost/mattermost-plugin-starter-template` (master branch): **Build files:** - `build/manifest/*.go` - `build/pluginctl/*.go` - `build/setup.mk` - `Makefile` **Config files:** - `.editorconfig` - `.gitattributes` - `.github/workflows/ci.yml` - `.gitignore` - `.golangci.yml` - `.nvmrc` - `go.mod` (for Go version only) - `server/.gitignore` When updating: - Preserve plugin-specific customizations (plugin ID, custom targets) - Update tool versions (golangci-lint, gotestsum, Node.js) - Adopt new linter configurations - Update Go version in `go.mod` if the starter template uses a newer version (compare the `go` directive). Also update the Go version in `.github/workflows/ci.yml` to match. After updating, run `go mod tidy` to update `go.sum` - Preserve license headers ### Phase 2: Fix linter issues 1. Run `make check-style` to identify issues 2. Install gofumpt if needed: `go install mvdan.cc/gofumpt@latest` 3. Run `gofumpt -w server/` to auto-fix formatting 4. Fix remaining issues manually ### Phase 3: Verify and commit 1. Run `make test` to verify all tests pass 2. Run `make check-style` to confirm 0 issues 3. Create a descriptive commit and PR. Use the pull request template from https://github.com/mattermost/.github/blob/master/PULL_REQUEST_TEMPLATE.md. ## Example commit message ``` Update common files from starter template and fix linter issues ``` ## Troubleshooting **Mock files have lint
