+name: git-workflow
+description: Enforce repository git workflow with platform-aware operations for GitHub (`gh`) and GitLab (`glab`), including branch naming, conventional commits, PR/MR creation and review, and issue creation using detected templates from `.github/` or `.gitlab/`. Use when handling branches, commits, pull/merge requests, reviews, or issue workflows.
+---
+
+# Git Workflow
+
+## Resolve Platform
+
+1. Detect platform in this order:
+   - Read `.copier/.copier-answers.yml` and use `git_platform` when present.
+   - Use repo markers: `.github/` -> `github`, `.gitlab/` -> `gitlab`.
+   - Parse `git remote get-url origin`:
+     - contains `github` -> `github`
+     - contains `gitlab` -> `gitlab`
+   - Fallback to `github`.
+2. Select CLI:
+   - `github` -> `gh`
+   - `gitlab` -> `glab`
+3. Verify CLI and auth before platform operations:
+   - `command -v gh && gh auth status`
+   - `command -v glab && glab auth status`
+4. If selected CLI is unavailable, continue local git operations and ask user to finish remote operations manually.
+
+## Detect Templates
+
+### GitHub Paths
+
+1. Pull request template candidates in priority order:
+   - `.github/pull_request_template.md`
+   - `.github/PULL_REQUEST_TEMPLATE.md`
+   - `.github/PULL_REQUEST_TEMPLATE/*.md` (alphabetical)
+2. Issue template candidates:
+   - `.github/ISSUE_TEMPLATE/*.md` (alphabetical, ignore `config.yml`)
+
+### GitLab Paths
+
+1. Merge request template candidates:
+   - `.gitlab/merge_request_templates/*.md` (alphabetical)
+2. Issue template candidates:
+   - `.gitlab/issue_templates/*.md` (alphabetical)
+
+### Template Rendering Rules
+
+1. Strip YAML frontmatter (`--- ... ---`) from issue templates before submitting.
+2. Remove placeholder HTML comments (`<!-- ... -->`).
+3. Keep original section headings and checklist items.
+4. Fill sections from context:
+   - Related issue: `Closes #<id>`
+   - Summary/proposed solution: concise bullets from current changes
+   - Breaking changes: `N/A` when none
+5. If no template exists, use a fallback body with:
+   - Related issue
+   - Summary of changes
+   - Breaking changes
+   - Checklist
+
+## Branch Workflow
+
+1. Require issue-first workflow before opening PR/MR.
+2. Create branch names as `<type>/<issue-id>-<short-slug>`.
+3. Use branch types:
+   - `feat`
+   - `fix`
+   - `refactor`
+   - `docs`
+   - `chore`
+   - `test`
+4. Prefer `feat|fix|refactor` for branch-triggered CI compatibility in this repo.
+
+```bash
+git fetch origin
+git checkout -b feat/<issue-id>-<short-slug>
+```
+
+## Commit Workflow
+
+1. Enforce Conventional Commits:
+   - `<type>(<scope>): <subject>`
+2. Use commit types:
+   - `feat`, `fix`, `refactor`, `docs`, `test`, `chore`, `ci`, `build`, `perf`, `revert`
+3. Keep subject imperative and concise.
+4. Add issue linkage in body when available (`Refs #<id>`).
+
+```bash
+git add -A
+git commit -m "<type>(<scope>): <subject>" -m "Refs #<issue-id>"
+```
+
+## Create PR Or MR
+
+1. Render template into a temporary body file.
+2. Use a title aligned with commit subject.
+3. Include issue linkage in body.
+4. Create request with platform CLI.
+
+### GitHub
+
+```bash
+gh pr create --title "<type>(<scope>): <subject>" --body-file .git/PR_BODY.md --base main
+```
+
+### GitLab
+
+```bash
+glab mr create --title "<type>(<scope>): <subject>" --description "$(cat .git/PR_BODY.md)" --target-branch main --source-branch "$(git branch --show-current)" --yes
+```
+
+## Review PR Or MR
+
+### GitHub
+
+```bash
+gh pr view <pr-number>
+gh pr checks <pr-number>
+gh pr review <pr-number> --approve
+gh pr review <pr-number> --request-changes --body "Please address requested changes."
+```
+
+### GitLab
+
+```bash
+glab mr view <mr-iid>
+glab ci status
+glab mr approve <mr-iid>
+glab mr note <mr-iid> -m "Request changes: please address reviewer feedback."
+```
+
+Use `glab mr note` as the request-changes action in GitLab workflows.
+
+## Create Issues With Templates
+
+1. Select issue template by intent:
+   - bug -> first match containing `bug`
+   - feature -> first match containing `feature`
+   - fallback -> first available template
+2. Render template with concise, concrete sections.
+3. Create issue with platform CLI.
+
+### GitHub
+
+```bash
+gh issue create --title "<Issue title>" --body-file .git/ISSUE_BODY.md
+```
+
+### GitLab
+
+```bash
+glab issue create --title "<Issue title>" --description "$(cat .git/ISSUE_BODY.md)" --yes
+```
+
+## Merge Workflow
+
+1. Verify checks/pipeline status before merge.
+2. Keep merge strategy consistent with repository preferences.
+3. Ensure linked issue is present before merge.
+
+### GitHub
+
+```bash
+gh pr merge <pr-number> --squash
+```
+
+### GitLab
+
+```bash
+glab mr merge <mr-iid> --squash --yes
+```
