Commands
1. scan_project
Purpose: Build a comprehensive mental model of the project.
Steps:
- Read
CLAUDE.md(root) for project conventions and build commands - Read
documents/GameDesignDocument.mdfor game rules - Read
documents/TechnicalArchitectureDocument.mdfor architecture overview - Scan source directory structures using Explore agents (parallelize client + server)
- 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
- 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
- Produce structured summary with:
- Architecture overview diagram - Module inventory table - Design patterns identified - Inconsistencies or gaps found
- Save findings to memory for future sessions
2. generate_tech_doc
Purpose: Generate or update documents/TechnicalArchitectureDocument.md.
Steps:
- Run
scan_projectif not done this session - Read core source files deeply (Game.js, Board.js, ActionQueue.js, BaseModule.js, EventBus.js, etc.)
- Also read server entry point and room logic for complete picture
- 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
- Cross-reference with existing
documents/TechnicalArchitectureDocument.mdif it exists - Present draft to user for review
- Write to file only after approval
- Update memory with new architectural findings
3. edit_idea
Purpose: Collaboratively refine a game feature idea before any code is written.
Steps:
- Extract the idea from conversation context (or ask user to describe it)
- Read relevant GDD sections (
documents/GameDesignDocument.md) - Read relevant Tech Doc sections (
documents/TechnicalArchitectureDocument.md) - 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
- 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)
- Iterate with user until refined
- 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:
- Read
documents/GameDesignDocument.mdin full - Identify correct section (match GDD's 17-section structure)
- 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)
- Present diff to user
- Apply only after explicit approval
- Flag downstream impacts on Tech Doc and code
- After GDD update, suggest updating
documents/TechnicalArchitectureDocument.mdif architecture is affected
5. check_design_consistency
Purpose: Verify GDD ↔ Tech Doc ↔ Source Code alignment.
Steps:
- Read GDD — extract all game rules, constants, and enumerations
- Read Tech Doc — extract technical specifications
- 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
- Build consistency matrix (table format):
examples
| Rule | GDD | Tech Doc | Client Code | Server Code | Status |
|---|---|---|---|---|---|
| Win Point | 600 | 600 | Board.json:pointOpenGate | Room.kt:? | ? |
- Check specifically:
- Win condition - Game mechanics
- Report all mismatches with severity levels
- 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:
- Read the approved design from documents
- Identify target files and modules (both client and server if needed)
- Read ALL target files to understand current patterns
- 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
- 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
- Plan implementation — present file list with approach for each
- After user approval, generate code
- Create/update tests (Jest for client, Kotlin tests for server)
- Run
check_design_consistencyto verify alignment - If server packets changed, remind user to run
./gradlew runto regenerate MSerializer.js
7. refactor_codebase
Purpose: Refactor code while maintaining design consistency.
Steps:
- Run
scan_projectto understand current state - Identify refactoring scope and goals
- Classify: behavior change or pure refactoring?
- If behavior changes: run
edit_idea→update_gddfirst - 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
- Execute after approval
- Run
check_design_consistencyafter refactoring - 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:
- 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
- Run automated checks (see
references/validation.mdfor 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` - 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
- Classify failures by severity:
- CRITICAL → fix immediately, re-run command - WARNING → flag to user, proceed with caveats - INFO → log for awareness
- Generate Validation Report:
## Validation Report — {command_name} | # | Check | Result | Severity | |---|-------|--------|----------| | 1 | Client lint | PASS | — | | 2 | Server build | PASS | — | |... **Overall: PASS / FAIL** - 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:
- Read before write. Always read existing source files before modifying them. Use Explore agents for broad scans, Read tool for specific files.
- Document before code. Change order:
- GDD first (if game rules change) - Tech Doc second (if architecture changes) - Code last
- User approval at every gate. Present drafts and plans before writing. The user is the product owner.
- Preserve consistency. After every change, verify GDD ↔ Tech Doc ↔ Code alignment. Offer
check_design_consistencywhen in doubt. - 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
- 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
- Save to memory. After completing a command, save key findings and decisions to memory files for future sessions.
- Validate every output. After every command, run
validate_resultautomatically:
- 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"
