[plan] Create workflow template library for 7 high-value automation patterns

[github-actions]

Objective

Create a library of 7 reusable workflow templates based on high-performing patterns identified in research, making it easier for users to start with proven automation patterns.

Context

Research identified 7 distinct workflow categories with excellent performance. Formalizing these as templates will help users quickly implement common automation patterns without starting from scratch.

Templates to Create

1. PR Code Review Automation - Analyze code changes → Post PR comment (BE-1, FE-2, FE-3, QA-1)
2. Scheduled Monitoring with Alerting - Query API/data → Detect issues → Create GitHub issue (BE-2, DO-1, DO-2, QA-2)
3. Visual Testing Automation - Playwright + artifact uploads + PR comments (FE-1)
4. On-Demand Report Generation - Aggregate data → Format → Post discussion (PM-1, PM-2)
5. Multi-Phase Analysis Pipelines - Data collection → Analysis → Historical tracking → Reporting (QA-2)
6. Rate-Limited Automation - Detect items → Prioritize → Create limited PRs/issues (DO-2)
7. API Integration with Persistence - External API → Compare to baseline (repo-memory) → Alert (BE-2)

Approach

1. Create template directory: .github/workflows/templates/

2. Extract patterns from high-scoring scenarios:

   • Visual regression testing (5.0) → Template 3
   • Flaky test tracking (5.0) → Template 5
   • Security scanner (5.0) → Template 6
   • API performance monitoring (5.0) → Template 7

3. Each template includes:

   • Markdown workflow file with placeholders
   • Configuration checklist
   • Common variations
   • Usage examples
   • Link to source scenario from research

4. Update agent instructions to reference templates when appropriate

Files to Create

• Create: .github/workflows/templates/pr-code-review.md
• Create: .github/workflows/templates/scheduled-monitoring.md
• Create: .github/workflows/templates/visual-testing.md
• Create: .github/workflows/templates/on-demand-report.md
• Create: .github/workflows/templates/multi-phase-analysis.md
• Create: .github/workflows/templates/rate-limited-automation.md
• Create: .github/workflows/templates/api-persistence.md
• Create: .github/workflows/templates/README.md (template catalog)
• Update: .github/instructions/developer.instructions.md (reference templates)

Acceptance Criteria

• All 7 templates created with working placeholder workflows
• Each template has clear configuration checklist
• Templates include 2-3 common variations
• Template catalog README documents when to use each template
• Agent instructions reference templates for matching scenarios
• At least 3 templates tested by compiling and running

Expected Impact

Reduces time-to-first-workflow from 25 minutes to under 5 minutes for common patterns, leveraging proven high-quality examples from research.
