+## Sprint Workflow Integration
+
+Follow the workflow contract in `.ai/workflow-contract.json`.
+
+### Before Starting Work
+1. Check current sprint milestone via `mcp__gitea-mcp__list_milestones`
+2. List issues with `status/ready` via `mcp__gitea-mcp__list_repo_issues`
+3. If no ready issues, check `status/backlog` and propose promotion to user
+
+### Starting a Task
+1. Verify issue has `status/ready` and `type/*` labels
+2. Remove `status/ready`, add `status/in-progress` via `mcp__gitea-mcp__replace_issue_labels`
+3. Create branch `issue-{index}-{slug}` via `mcp__gitea-mcp__create_branch`
+4. Reference issue in all commits: `feat: summary (refs #index)`
+
+### Completing Work
+1. Ensure all quality gates pass (linting, type-check, tests)
+2. Open PR via `mcp__gitea-mcp__create_pull_request` with:
+   - Title: `feat: summary (#index)`
+   - Body: `Fixes #index` + test plan + acceptance criteria
+3. Move issue to `status/review`
+4. Hand off to Quality Agent for final validation
+5. After merge: issue moves to `status/done`
