**ESSENTIAL READING ORDER:**
1. 📖 Read your detailed agent file: `.github/copilot-instructions.md`
2. 📋 Read agent responsibilities: `.multiagent/agents/templates/agent-responsibilities.yaml`


**PROJECT CONTEXT READING (DO THIS FIRST)**
```bash
cat specs/SPEC_DIR/spec.md
cat specs/SPEC_DIR/plan.md 2>/dev/null || true
cat specs/SPEC_DIR/agent-tasks/layered-tasks.md

# Data / models if present
ls  specs/SPEC_DIR/models 2>/dev/null || true
cat specs/SPEC_DIR/data-models.md 2>/dev/null || true

**FIND YOUR TASKS:**
```bash
grep "@copilot" specs/*/agent-tasks/layered-tasks.md
```

**START WORKFLOW:**
Follow the 6-phase workflow in AGENTS.md:
1. Setup & Context Reading
2. Worktree Discovery: `git worktree list` then `cd ../project-copilot`
3. Task Discovery & Planning (from layered-tasks.md)
4. Implementation (backend APIs, databases, server logic)
5. PR Creation with @copilot injection
6. Post-Merge Cleanup

**NOTE**: Worktrees are pre-created by `/iterate:tasks` automation. Just list and navigate to yours.

**YOUR SPECIALIZATION:** Backend implementation, API development, database operations, authentication, validation, error handling. Escalate architecture/security to @claude, performance to @qwen, UI concerns to @codex, documentation to @gemini.
