Orchestration Skill

Orchestrate agents to complete any task by intelligently breaking it down, selecting the optimal execution strategy, and ensuring complete delivery with quality verification.

Core Principles

Complete the task fully - Never stop until everything is done
Choose the right strategy - Parallel when possible, sequential when necessary
Quality is non-negotiable - Every phase must pass quality gates
Self-healing - Fix all issues found in review automatically
Double-check everything - Verify completion before reporting done
Production-ready code only - No workarounds, no technical debt, no code smells

Implementation Standards (CRITICAL)

Every implementation MUST be production-ready:

No workarounds: Implement the proper solution, not quick hacks or temporary fixes
No technical debt: Do not defer work with TODOs or "fix later" comments
No code smells: Follow clean code principles, avoid duplication, keep functions focused
Full implementation: Complete the feature end-to-end, including error handling, edge cases, and validation
Production quality: Write code as if it will be deployed immediately after merge

If the "right" solution is unclear:

Ask for clarification before implementing
Research existing patterns in the codebase
Choose the approach that is maintainable long-term, not just the fastest to implement

Phase 1: Task Analysis

Step 1.1: Understand the Task

Parse the task description to identify:

Scope: Backend (Server Components, Actions), frontend (Client Components), full-stack
Type: Feature, bug fix, refactoring, documentation, migration
Complexity: Simple (1-2 files), Medium (3-10 files), Complex (10+ files or architectural)
Component type: Server Component, Client Component, Server Action

Step 1.2: Explore Codebase

Spawn Explore agent to understand affected areas:

Task: Explore codebase for: {task description}

Find:
1. Related existing implementations
2. Patterns and conventions used
3. Files likely to be affected
4. Dependencies and imports
5. Server vs Client component boundaries

Thoroughness: {quick|medium|very thorough based on complexity}

Step 1.3: Break Into Phases

Create atomic phases that can be independently completed. Each phase should:

Have a single, clear deliverable
Be testable in isolation
Take no more than one agent to complete
Have clear success criteria

Example breakdown for "Add question bookmarking":

Phase 1: Database - Add bookmarks table to schema
Phase 2: Backend - Create Server Actions for bookmark operations
Phase 3: Frontend - Build bookmark button component (Client)
Phase 4: Frontend - Integrate bookmark into QuestionCard
Phase 5: Testing - Verify in browser

Step 1.4: Map Dependencies

Create dependency graph:

Phase 1 (DB) → Phase 2 (Server Actions) → Phase 3 (UI) + Phase 4 (Integration)
                                        ↘ Phase 5 (Testing)

Identify:

Independent phases: Can run in parallel
Dependent phases: Must run sequentially
Blocking phases: Other phases wait for this

Phase 2: Strategy Selection

Decision Matrix

Task Characteristics	Strategy	Rationale
All phases independent	Parallel	Maximum speed
Linear dependency chain	Sequential	Each phase needs previous output
Some independent, some dependent	Hybrid	Parallel where safe, sequential where needed
Long-running + quick phases	Background	Don't block on slow operations
Unknown dependencies	Sequential	Safest approach

Parallel Strategy

Use when phases don't share:

Same files
Database state
Generated code
Global configuration

# Spawn multiple agents in ONE message
Task(agent1) + Task(agent2) + Task(agent3)

Example: Updating 3 independent components

Sequential Strategy

Use when:

Phase N outputs are Phase N+1 inputs
Database migrations must complete before Server Action work
Types must be defined before component work

# Wait for each to complete before next
Task(phase1) → wait → Task(phase2) → wait → Task(phase3)

Example: DB migration → Server Action → Client Component integration

Background Strategy

Use when:

Running quality gates while reviewing code
Building while working on documentation
Type checking while exploring next phase

# Start background task
Task(background_agent, run_in_background=true)

# Continue with other work
Task(foreground_agent)

# Check background result when needed
TaskOutput(background_agent_id)

Hybrid Strategy (Most Common)

Combine strategies based on dependency graph:

Phase 1 (DB) - Sequential first
    ↓
Phase 2 (Server Actions) - Sequential, depends on Phase 1
    ↓
Phase 3+4+5 (Components) - Parallel, all depend on Phase 2
    ↓
Phase 6 (Integration) - Sequential, depends on 3+4+5

Phase 3: Execution

Step 3.1: Initialize Tracking

Use TodoWrite to track all phases:

TodoWrite([
  {
    content: 'Phase 1: {description}',
    status: 'pending',
    activeForm: 'Working on Phase 1',
  },
  {
    content: 'Phase 2: {description}',
    status: 'pending',
    activeForm: 'Working on Phase 2',
  },
  // ... all phases
  {
    content: 'Quality gates verification',
    status: 'pending',
    activeForm: 'Running quality gates',
  },
  {
    content: 'Browser verification',
    status: 'pending',
    activeForm: 'Verifying in browser',
  },
])

Step 3.2: Execute Phases

For each phase, spawn the appropriate agent:

Software Engineer Agent (Most Common)

Task: Implement {phase description}

## Context
- Feature: {overall task}
- Phase: {N} of {total}
- Dependencies completed: {list}

## Deliverables
{specific files and changes expected}

## Constraints
- Follow existing patterns in codebase
- Default to Server Components unless interactivity required
- Use Server Actions for mutations (not API routes)
- No breaking changes to existing functionality
- Leave code in clean, working state

## Verification
{how to verify this phase is complete}

## Quality Gates
After implementation, run:
npm run check

Step 3.3: Monitor and Handle Results

For sequential phases:

result = await Task(agent)
if (result.failed) {
  // Fix immediately before continuing
  Task(software-engineer, "Fix issue: {error details}")
}
update_todo(phase, "completed")
continue_to_next_phase()

For parallel phases:

// Spawn all at once
task1 = Task(agent1, run_in_background=true)
task2 = Task(agent2, run_in_background=true)
task3 = Task(agent3, run_in_background=true)

// Wait for all
result1 = TaskOutput(task1)
result2 = TaskOutput(task2)
result3 = TaskOutput(task3)

// Handle any failures
for each failed result:
  Task(software-engineer, "Fix: {error}")

Step 3.4: Handle Failures

When an agent fails:

Analyze the error - Is it a code issue or dependency issue?
Fix immediately - Spawn software-engineer to fix
Re-verify - Run the phase again if needed
Update tracking - Keep todos accurate

if phase.failed:
  Todo: Mark phase as "in_progress" again
  Task(software-engineer): "Fix error in Phase {N}: {error details}"
  Verify fix worked
  Then continue

Phase 4: Quality Verification

Step 4.1: Run Quality Gates

After ALL phases complete:

npm run check && npm run build

If any fail:

Identify which phase caused the issue
Spawn software-engineer to fix
Re-run quality gates
Loop until all pass

Step 4.2: Verify in Browser

Test as a user would:

Start dev server: npm run dev
Open http://localhost:3000 in browser
Navigate to affected pages/features
Verify Server/Client component boundaries work
Test the new functionality end-to-end

Step 4.3: Fix All Issues

For every issue found:

Spawn software-engineer to fix
Re-run quality gates
Re-verify in browser if significant changes

while (issues.length > 0):
  for each issue:
    Task(software-engineer, "Fix: {issue description}")

  run_quality_gates()
  verify_in_browser()
  issues = gather_remaining_issues()

Phase 5: Finalization

Step 5.1: Double-Check Completion

Verify ALL original requirements are met:

Original task: {$ARGUMENTS}

Checklist:
[ ] All phases completed and verified
[ ] Quality gates pass
[ ] Browser verification passed
[ ] Code works as expected (end-to-end)
[ ] No regressions introduced

Step 5.2: Final Quality Gates

One more pass to ensure clean state:

npm run check && npm run build

Step 5.3: Report Completion

Provide summary to user:

## Task Complete: {task description}

### Phases Completed
1. {Phase 1} - {status and notes}
2. {Phase 2} - {status and notes}
...

Snowflake Quiz Specific Guidelines

Quality Gates Command

npm run check && npm run build

npm run check runs:

TypeScript strict mode checking
ESLint with Next.js rules (zero warnings)
Prettier formatting check

Database Changes

When schema changes are needed:

npm run db:migrate  # Apply Drizzle migrations

Architecture Patterns

Server Components (Default)

No 'use client' directive. Can use async/await, direct DB access.

// app/stats/page.tsx
import { getStats } from '@/lib/db/queries'

export default async function StatsPage() {
  const stats = await getStats()
  return <StatsDisplay stats={stats} />
}

Client Components

Must have 'use client'. Use for interactivity.

// components/quiz/QuestionCard.tsx
'use client'
import { useState } from 'react'

export function QuestionCard({ question }: Props) {
  const [selected, setSelected] = useState<number[]>([])
  // Interactive logic
}

Server Actions

For mutations. Mark with 'use server'.

// lib/actions/quiz.ts
'use server'
import { revalidatePath } from 'next/cache'

export async function submitAnswer(sessionId: string, answers: number[]) {
  // Save to database
  revalidatePath(`/quiz/${sessionId}`)
}
