Commands

1. scan_project

Purpose: Build a comprehensive mental model of the project.

Steps:

1. Read CLAUDE.md (root) for project conventions and build commands
2. Read documents/GameDesignDocument.md for game rules
3. Read documents/TechnicalArchitectureDocument.md for architecture overview
4. Scan source directory structures using Explore agents (parallelize client + server)
5. For the client, focus on:
   • client_$project_name/src/modules/ — module inventory
   • client_$project_name/src/modules/game/logic/ — core game objects
   • client_$project_name/src/events/ — event catalog
   • client_$project_name/res/config/ — config file inventory
6. For the server, focus on:
   • server_$project_name/src/main/kotlin/org/_$project_name/modules/ — server modules
   • server_$project_name/src/main/kotlin/org/_$project_name/abilities/ — ability system
7. Produce structured summary with:
   • Architecture overview diagram
   • Module inventory table
   • Design patterns identified
   • Inconsistencies or gaps found
8. Save findings to memory for future sessions

2. generate_tech_doc

Purpose: Generate or update documents/TechnicalArchitectureDocument.md.

Steps:

1. Run scan_project if not done this session
2. Read core source files deeply (Game.js, Board.js, ActionQueue.js, BaseModule.js, EventBus.js, etc.)
3. Also read server entry point and room logic for complete picture
4. Document 16 sections covering: system overview, client/server architecture, communication protocol, game logic, event system, module system, action queue, card/ability system, config system, UI architecture, data flow, testing, cross-project deps, tech debt, ADRs
5. Cross-reference with existing documents/TechnicalArchitectureDocument.md if it exists
6. Present draft to user for review
7. Write to file only after approval
8. Update memory with new architectural findings

3. edit_idea

Purpose: Collaboratively refine a game feature idea before any code is written.

Steps:

1. Extract the idea from conversation context (or ask user to describe it)
2. Read relevant GDD sections (documents/GameDesignDocument.md)
3. Read relevant Tech Doc sections (documents/TechnicalArchitectureDocument.md)
4. Analyze against:
   • Game balance: How does this affect KC economy, diamond flow, card power?
   • Technical feasibility: Client-server sync, ActionQueue integration, event flow
   • Existing patterns: Does it fit BaseModule, ActionQueue, EventBus patterns?
   • Cross-project impact: Client + server + config changes needed?
   • Player experience: Fun factor, complexity, learning curve
5. Present structured review:
   • Summary: What the idea adds or changes
   • Impact Analysis: Which systems, modules, and files are affected
   • Risks: Balance concerns, tech debt, complexity
   • Suggestions: Improvements, alternatives, edge cases
   • Affected Files: Specific file paths on both client and server
   • Estimated Scope: Small (1-2 files) / Medium (3-8 files) / Large (9+ files)
6. Iterate with user until refined
7. When approved, suggest: update_gdd → generate_code_from_design

4. update_gdd

Purpose: Update the Game Design Document with a new or modified feature.

Steps:

1. Read documents/GameDesignDocument.md in full
2. Identify correct section (match GDD's 17-section structure)
3. Draft update using GDD's existing style:
   • Tables for constants and enums
   • Pipe-delimited tables for mechanics
   • Code blocks for sequences/flows
   • Section numbering (§1-§17)
4. Present diff to user
5. Apply only after explicit approval
6. Flag downstream impacts on Tech Doc and code
7. After GDD update, suggest updating documents/TechnicalArchitectureDocument.md if architecture is affected

5. check_design_consistency

Purpose: Verify GDD ↔ Tech Doc ↔ Source Code alignment.

Steps:

1. Read GDD — extract all game rules, constants, and enumerations
2. Read Tech Doc — extract technical specifications
3. Scan source code for implementations:
   • client_$project_name/res/config/ — game config, game constants
   • client_$project_name/src/modules/game/logic/ — game logic
   • Server Room.kt, Board.kt — server-side validation constants
4. Build consistency matrix (table format):

examples

Rule	GDD	Tech Doc	Client Code	Server Code	Status
Win Point	600	600	Board.json:pointOpenGate	Room.kt:?	?

5. Check specifically:
   • Win condition
   • Game mechanics
6. Report all mismatches with severity levels
7. Suggest fixes: always update docs first, then code

6. generate_code_from_design

Purpose: Generate code from an approved, documented design.

Prerequisites: Feature MUST be documented in GDD and/or Tech Doc first.

Steps:

1. Read the approved design from documents
2. Identify target files and modules (both client and server if needed)
3. Read ALL target files to understand current patterns
4. For client code, follow these patterns:
   • Game logic: extend BaseAction for new effects, register in ActionQueue
   • New module: extend BaseModule, register in ModuleMgr
   • Events: add to EventKeys.js, use gv.bus.emit() / gv.bus.on()
   • Config: add JSON to res/config/, load via ResourcesMgr
   • UI: extend BaseGUI or BaseUINode
5. For server code, follow:
   • New abilities: add ActionSkill enum, implement in abilities/execute/
   • Game commands: add to RoomRequestHandler, create cmd/ packet classes
   • Config: add to config/ package, register in GameCfg
6. Plan implementation — present file list with approach for each
7. After user approval, generate code
8. Create/update tests (Jest for client, Kotlin tests for server)
9. Run check_design_consistency to verify alignment
10. If server packets changed, remind user to run ./gradlew run to regenerate MSerializer.js

7. refactor_codebase

Purpose: Refactor code while maintaining design consistency.

Steps:

1. Run scan_project to understand current state
2. Identify refactoring scope and goals
3. Classify: behavior change or pure refactoring?
4. If behavior changes: run edit_idea → update_gdd first
5. If pure refactoring:
   • Update documents/TechnicalArchitectureDocument.md with new structure
   • Present refactoring plan: before/after per file, migration steps
   • For event bus migration: ensure both old (SignalMgr) and new (EventBus) work during transition
6. Execute after approval
7. Run check_design_consistency after refactoring
8. Update tests

8. validate_result

Purpose: Validate the output of any preceding skill command to ensure correctness before trusting results.

Trigger: Runs automatically after every other command. Can also be invoked manually.

Steps:

1. Identify which command just completed and its output type:
   • Scan/Analysis → verify counts, file paths, architecture claims
   • Documentation → verify sections, code examples, accuracy
   • Idea Editing → verify impact areas, cross-project coverage
   • GDD Update → verify formatting, section structure, no contradictions
   • Consistency Check → verify matrix values against actual sources
   • Code Generation → verify lint/build, JSB, tests, registration (both client + server)
   • Refactoring → verify build/tests before/after, consistency
2. Run automated checks (see references/validation.md for command-specific checks):

   # Client checks
   cd client_$project_name && npm run lint 2>&1 | tail -5
   cd client_$project_name && npm test 2>&1 | tail -10
   grep -rE '`[^`]*\$\{' client_$project_name/src/ --include="*.js"   # JSB
   # Server checks
   cd server_$project_name && ./gradlew compileKotlin 2>&1 | tail -5
   cd server_$project_name && ./gradlew test 2>&1 | tail -10
   

3. Run spot-checks (pick 3 random items from output):
   • Verify file paths exist on both client and server
   • Verify counts match actual codebase
   • Verify design pattern claims match actual code
4. Classify failures by severity:
   • CRITICAL → fix immediately, re-run command
   • WARNING → flag to user, proceed with caveats
   • INFO → log for awareness
5. Generate Validation Report:

   ## Validation Report — {command_name}
   | # | Check | Result | Severity |
   |---|-------|--------|----------|
   | 1 | Client lint | PASS | — |
   | 2 | Server build | PASS | — |
   | ...
   **Overall: PASS / FAIL**
   

6. Decision:
   • All PASS → proceed, save to memory
   • WARNING only → proceed with caveats noted
   • Any CRITICAL → stop, fix, re-validate
   • Multiple CRITICAL → re-run entire command from scratch

Workflow Rules

These rules apply to ALL commands:

1. Read before write. Always read existing source files before modifying them. Use Explore agents for broad scans, Read tool for specific files.

2. Document before code. Change order:

   • GDD first (if game rules change)
   • Tech Doc second (if architecture changes)
   • Code last

3. User approval at every gate. Present drafts and plans before writing. The user is the product owner.

4. Preserve consistency. After every change, verify GDD ↔ Tech Doc ↔ Code alignment. Offer check_design_consistency when in doubt.

5. Respect existing patterns. Match code style and patterns already in the codebase:

   • Client: BaseModule, ActionQueue, EventBus, gv.* globals
   • Server: Actor model, command routing, KSP serialization

6. Scope awareness. Cross-project changes (client + server) need extra care:

   • Check if MSerializer.js needs regeneration
   • Check if ItemGroup.json needs update
   • Verify both client and server handle the same packet format

7. Save to memory. After completing a command, save key findings and decisions to memory files for future sessions.

8. Validate every output. After every command, run validate_result automatically:

   • Automated checks: lint/build, JSB compat, tests, counts, file paths (both client + server)
   • Spot-checks: 3 random items verified against actual codebase
   • Severity classification: CRITICAL (fix now), WARNING (flag), INFO (log)
   • CRITICAL failures block proceeding until fixed
   • See references/validation.md for command-specific validation checks

---

Response Format

• Tables for comparisons, inventories, and consistency checks
• Bullet lists for action items and recommendations
• Code blocks for file paths, commands, and snippets
• Section headers for multi-part responses
• Always state which command is executing and current step
• For multi-command flows, state the pipeline upfront:

  "Pipeline: edit_idea → update_gdd → generate_code_from_design"
