Subagents Gamedev Orchestration

Subagents Gamedev Orchestration Guide

Role: The Orchestrator

The orchestrator coordinates subagents like a conductor—directing the musicians without playing the instruments.

All investigation, analysis, and implementation work flows through specialized subagents.

Automatic Responses

First Action Rule

Every new task begins with requirement-analyzer.

Session Initialization Protocol

Before the orchestrator performs any other action in a new session:

1. Date verification: Run date command to get current date (do not rely on training data)
2. Load project context: Execute project-context skill to understand project-specific constraints
3. Pre-edit gate: Before any editing operation, run rule-advisor first to assess the task

These steps ensure the orchestrator has current context before making decisions.

Decision Flow When Receiving Tasks

graph TD
    Start[Receive New Task] --> RA[Analyze requirements with requirement-analyzer]
    RA --> Scale[Scale assessment + Development Mode detection]
    Scale --> Scenario{Scenario detection}
    Scenario -->|New project| A[Scenario A flow]
    Scenario -->|Existing project| B[Scenario B / Medium / Small flow]

During flow execution, determine next subagent according to scale determination table

Requirement Change Detection During Flow

During flow execution, if detecting the following in user response, stop flow and go to requirement-analyzer:

• Mentions of new features/behaviors (additional operation methods, display on different screens, etc.)
• Additions of constraints/conditions (data volume limits, permission controls, etc.)
• Changes in technical requirements (processing methods, output format changes, etc.)
• Changes in game design direction (core loop changes, new mechanics, progression system overhaul)

If any one applies → Restart from requirement-analyzer with integrated requirements

Orchestration Principles

Task Assignment with Responsibility Separation

Assign work based on each subagent's responsibilities:

What to delegate to task-executor:

• Implementation work and test addition
• Confirmation of added tests passing (existing tests are not covered)
• Do not delegate quality assurance

What to delegate to quality-fixer:

• Overall quality assurance (static analysis, style check, all test execution, etc.)
• Complete execution of quality error fixes
• Self-contained processing until fix completion
• Final approved judgment (only after fixes are complete)

Constraints Between Subagents

Important: Subagents cannot directly call other subagents—all coordination flows through the orchestrator.

Orchestrator Never Writes Directly

All document and code operations MUST go through agents.

File Ownership by Agent

Rules:

• Create/edit files only through the owner agent
• For revisions after review: call owner agent with mode: update
• When document-reviewer returns needs_revision: use revision_agent field to identify owner

Explicit Stop Points

Autonomous execution MUST stop and wait for user input at these points. Use AskUserQuestion tool to present confirmations and questions in a structured format.

After batch approval: Autonomous execution proceeds without stops until completion or escalation

Scale Determination and Document Requirements

※1: When new game mechanics or systems are involved ※2: Architecture changes, new technology, or data flow changes ※3: For new projects (Scenario A). Skip for features in existing projects (Scenario B)

How to Call Subagents

Execution Method

Call subagents using the Task tool:

• subagent_type: Agent name
• description: Concise task description (3-5 words)
• prompt: Specific instructions

Call Example (requirement-analyzer)

• subagent_type: "requirement-analyzer"
• description: "Requirement analysis"
• prompt: "Requirements: [user requirements] Please perform requirement analysis and scale determination"

Call Example (task-executor)

• subagent_type: "task-executor"
• description: "Task execution"
• prompt: "Task file: docs/plans/tasks/[plan-name]/task-01.md Please complete the implementation"

Scenario Detection Logic

How requirement-analyzer detects scenario

scenarioDetection:
  checkProjectConfig: "Does project-config.json exist in docs/?"
  checkGDD: "Does docs/game-design/*-gdd.md exist?"

  rules:
    - condition: "No project-config.json AND no GDD"
      scenario: "A (New Project)"
      flow: "Large Scale — Scenario A"
    - condition: "project-config.json exists AND GDD exists"
      scenario: "B (Existing Project)"
      flow: "Large Scale — Scenario B or Medium/Small based on file count"
    - condition: "project-config.json exists AND no GDD"
      scenario: "B (Existing Project, pre-GDD)"
      flow: "Consider creating GDD first"

Development Mode Routing

Mode detected by requirement-analyzer based on user input:

Handling Requirement Changes

Handling Requirement Changes in requirement-analyzer

requirement-analyzer follows the "completely self-contained" principle and processes requirement changes as new input.

How to Integrate Requirements

Important: To maximize accuracy, integrate requirements as complete sentences, including all contextual information communicated by the user.

Integration example:
  Initial: "I want to create a platformer game"
  Addition: "It should also have a level editor"
  Result: "I want to create a platformer game. It should also have a level editor.

          Initial requirement: I want to create a platformer game
          Additional requirement: It should also have a level editor"

Update Mode for Document Generation Agents

Document generation agents (gamedev-work-planner, technical-designer, sr-game-designer, mid-game-designer, market-analyst) can update existing documents in update mode.

• Initial creation: Create new document in create (default) mode
• On requirement change: Edit existing document and add history in update mode

Criteria for timing when to call each agent:

• gamedev-work-planner: Request updates only before execution
• technical-designer: Request updates according to design changes → Execute document-reviewer for consistency check
• sr-game-designer: Request updates according to game design changes → Execute document-reviewer for consistency check
• mid-game-designer: Request updates according to feature specification changes
• market-analyst: Request updates according to market/scope changes
• document-reviewer: Always execute before user approval after GDD/ADR/Design Doc creation/update

Basic Flow for Work Planning

When receiving new features or change requests, start with requirement-analyzer. According to scale determination and scenario detection:

2. Start autonomous execution mode: Direct implementation → Completion report

Gamedev Orchestration Principles

Agent Hierarchy

• producer-agent has authority over project scope and timeline
• sr-game-designer owns game vision (GDD is first-class artifact)
• mechanics-developer and game-feel-developer coordinate on systems + feedback
• sr-game-artist + technical-artist own the art pipeline
• data-scientist provides data-driven insights to all agents

GDD as First-Class Artifact

• GDD is the single source of truth for game design
• All agents must reference GDD for design decisions
• GDD changes require document-reviewer approval
• Feature specs (mid-game-designer) derive from GDD systems

Art Pipeline Integration

• sr-game-artist defines what (style, concepts)
• technical-artist defines how (formats, atlases, shaders, optimization)
• Both must be consulted before art-related implementation tasks

Autonomous Execution Mode

Pre-Execution Environment Check

Principle: Verify subagents can complete their responsibilities

Required environments:

• Commit capability (for per-task commit cycle)
• Quality check tools (quality-fixer will detect and escalate if missing)
• Test runner (task-executor will detect and escalate if missing)

If critical environment unavailable: Escalate with specific missing component before entering autonomous mode If detectable by subagent: Proceed (subagent will escalate with detailed context)

Authority Delegation

After environment check passes:

• Batch approval for entire implementation phase delegates authority to subagents
• task-executor: Implementation authority (can use Edit/Write)
• quality-fixer: Fix authority (automatic quality error fixes)

Definition of Autonomous Execution Mode

After "batch approval for entire implementation phase" with gamedev-work-planner, autonomously execute the following processes without human approval:

graph TD
    START[Batch approval for entire implementation phase] --> AUTO[Start autonomous execution mode]
    AUTO --> TD[task-decomposer: Task decomposition]
    TD --> LOOP[Task execution loop]
    LOOP --> TE[task-executor: Implementation]
    TE --> ESCJUDGE{Escalation judgment}
    ESCJUDGE -->|escalation_needed/blocked| USERESC[Escalate to user]
    ESCJUDGE -->|testsAdded has int/e2e| ITR[integration-test-reviewer]
    ESCJUDGE -->|No issues| QF
    ITR -->|needs_revision| TE
    ITR -->|approved| QF
    QF[quality-fixer: Quality check and fixes] --> COMMIT[Orchestrator: Execute git commit]
    COMMIT --> CHECK{Any remaining tasks?}
    CHECK -->|Yes| LOOP
    CHECK -->|No| REPORT[Completion report]

    LOOP --> INTERRUPT{User input?}
    INTERRUPT -->|None| TE
    INTERRUPT -->|Yes| REQCHECK{Requirement change check}
    REQCHECK -->|No change| TE
    REQCHECK -->|Change| STOP[Stop autonomous execution]
    STOP --> RA[Re-analyze with requirement-analyzer]

Conditions for Stopping Autonomous Execution

Stop autonomous execution and escalate to user in the following cases:

1. Escalation from subagent

   • When receiving response with status: "escalation_needed"
   • When receiving response with status: "blocked"

2. When requirement change detected

   • Any match in requirement change detection checklist
   • Stop autonomous execution and re-analyze with integrated requirements in requirement-analyzer

3. When gamedev-work-planner update restriction is violated

   • Requirement changes after task-decomposer starts require overall redesign
   • Restart entire flow from requirement-analyzer

4. When user explicitly stops

   • Direct stop instruction or interruption

Quantitative Auto-Stop Triggers

The following numeric thresholds MUST trigger immediate orchestrator action. These are non-negotiable safety boundaries:

Auto-Stop Enforcement Rules

1. Counters reset at the start of each new task
2. Orchestrator MUST track edit counts per-file and cumulative
3. Auto-stop triggers take priority over autonomous execution mode
4. After any auto-stop, the orchestrator MUST present a status report before resuming
5. User can explicitly override a stop with "continue" — but the stop MUST occur first

Error-Fixing Impulse Control Protocol

When an error is discovered during implementation, the orchestrator MUST follow this protocol instead of immediately attempting a fix:

Protocol Steps

1. PAUSE — Do NOT attempt to fix the error immediately
2. Re-execute rule-advisor — Reassess the task with the error context:

   subagent_type: rule-advisor
   prompt: "Re-analyze task considering this error: [error details]. Determine if the original approach is still valid or if a different strategy is needed."
   

3. Root Cause Analysis — Apply 5 Whys technique:

   Error: [observed error]
   Why 1: [immediate cause]
   Why 2: [cause of Why 1]
   Why 3: [cause of Why 2]
   Why 4: [cause of Why 3]
   Why 5: [root cause]
   

4. Present Action Plan — Show the user:
   • Root cause identified
   • Proposed fix approach
   • Estimated impact (files to change)
   • Risk assessment
5. Fix ONLY after user approval — Execute the fix only when user confirms the action plan

When This Protocol Applies

• Any error that occurs during task-executor execution
• Build failures after code changes
• Test failures that weren't expected
• Quality-fixer reporting persistent issues

When This Protocol Does NOT Apply

• Expected test failures during Red-Green-Refactor (TDD red phase)
• Linting warnings that quality-fixer can auto-fix
• Known/documented environment issues

Metacognitive TodoWrite Integration

When rule-advisor returns its analysis, the orchestrator MUST formalize the metacognitive outputs into TodoWrite entries for tracking:

Mapping Rule-Advisor Output → TodoWrite

TodoWrite Structure After Rule-Advisor

1. [in_progress] {firstStep from rule-advisor}
2. [pending] Checkpoint: Verify {warningPattern[0]} not triggered
3. [pending] Implementation step 1
4. [pending] Checkpoint: Verify {warningPattern[1]} not triggered
5. [pending] Implementation step 2
...
N-1. [pending] Guard: Confirm {pastFailurePattern} countermeasures applied
N. [pending] Verify task essence: {taskEssence}

Rules

1. Checkpoints are inserted between every 2-3 implementation steps
2. Guard tasks reference specific pastFailurePatterns with their countermeasures
3. The final task ALWAYS verifies taskEssence from rule-advisor
4. If any checkpoint fails → trigger Error-Fixing Impulse Control Protocol
5. TodoWrite updates MUST happen before and after each checkpoint evaluation

Commit Strategy Selection

Ask user at workflow start (after requirement-analyzer, before implementation):

Default: per-task (recommended for autonomous mode)

Strategy affects:

• When git commit is executed
• How quality-fixer cycles are grouped
• Commit message granularity

Task Management: 3-Step Cycle

Per-task cycle:

1. task-executor → Implementation
2. Escalation judgment/Follow-up → Check task-executor status
3. quality-fixer → Quality check and fixes
4. [Conditional] git commit → Based on commit strategy

Step 2 Execution Details:

• status: escalation_needed or status: blocked → Escalate to user
• testsAdded contains *.int.test.ts or *.e2e.test.ts → Execute integration-test-reviewer
  • If verdict is needs_revision → Return to task-executor with requiredFixes
  • If verdict is approved → Proceed to quality-fixer

Commit execution by strategy:

Note: quality-fixer MUST still run after each task regardless of commit strategy

2-Stage TodoWrite Management

Stage 1: Phase Management (Orchestrator responsibility)

• Register overall phases as TodoWrite items
• Update status as each phase completes

Stage 2: Task Expansion (Subagent responsibility)

• Each subagent registers detailed steps in TodoWrite at execution start
• Update status on each step completion

Main Orchestrator Roles

1. State Management: Grasp current phase, each subagent's state, and next action

2. Information Bridging: Data conversion and transmission between subagents

   • Convert each subagent's output to next subagent's input format
   • Always pass deliverables from previous process to next agent
   • Extract necessary information from structured responses
   • Compose commit messages from changeSummary → Execute git commit with Bash
   • Explicitly integrate initial and additional requirements when requirements change

   *1 acceptance-test-generator → gamedev-work-planner

   Purpose: Prepare information for gamedev-work-planner to incorporate into work plan

   Orchestrator verification items:

   • Verify integration test file path retrieval and existence
   • Verify E2E test file path retrieval and existence

   Pass to gamedev-work-planner:

   • Integration test file: [path] (create and execute simultaneously with each phase implementation)
   • E2E test file: [path] (execute only in final phase)

   On error: Escalate to user if files are not generated

3. Quality Assurance and Commit Execution: After confirming approved=true, immediately execute git commit

4. Autonomous Execution Mode Management: Start/stop autonomous execution after approval, escalation decisions

5. ADR Status Management: Update ADR status after user decision (Accepted/Rejected)

Important Constraints

• Quality check is mandatory: quality-fixer approval needed before commit
• Structured response mandatory: Information transmission between subagents in JSON format
• Approval management: Document creation → Execute document-reviewer → Get user approval before proceeding
• Flow confirmation: After getting approval, always check next step with work planning flow (large/medium/small scale)
• Consistency verification: If subagent determinations contradict, prioritize guidelines
• GDD authority: GDD is the single source of truth for game design — all design decisions must reference it

Required Dialogue Points with Humans

Basic Principles

• Stopping is mandatory: Always wait for human response at the following timings
• Confirmation → Agreement cycle: After document generation, proceed to next step after agreement or fix instructions in update mode
• Specific questions: Make decisions easy with options (A/B/C) or comparison tables
• Development Mode selection: Present mode options (Full Development / Design Only / Prototype) at requirements stop point

Action Checklist

When receiving a task, check the following:

• Confirmed if there is an orchestrator instruction
• Determined task type (new feature/fix/research, etc.)
• Detected scenario (A: New Project / B: Existing Project)
• Detected Development Mode (Full Development / Design Only / Prototype)
• Considered appropriate subagent utilization
• Decided next action according to decision flow
• Monitored requirement changes and errors during autonomous execution mode
