VibeGame Build

This is a long-running delegation workflow. The lead sets a multi-stage implementation plan (potentially hours of work), delegates to teammates, and supervises execution. The lead does not implement directly — only tiny local edits qualify as self-service.

Core lead responsibilities in this mode:

• Understand: rebuild context from code, specs, and live verification
• Architect: design the multi-stage plan before any execution
• Supervise: delegate, track progress, and course-correct through teammates

Phase 1: Plan

Clarify the goal until it is concrete and actionable. Do not proceed to execution or use create_goal tool until the goal is aligned.

.vibegame/goal.md ## User Input holds the user's verbatim request, written there by a hook when this build was invoked. Confirm it is non-empty before anything else; if empty, paste the user's original words in yourself, unedited. GDD, prd.md and the final review all answer to it.

1. Use at most 3 Task-tool subagents (Claude Code Explore / Codex equivalent — NOT teammates spawned via vibegame lead) to inspect three discovery surfaces in parallel:
   • Current codebase — existing files, patterns, specs, implementation status.
   • modules/index.md — catalog of installed *Module.js Node scripts (one-line description + interface per module). Anything you can wire in directly via script: "XxxModule" or extend by subclassing is work the team does not have to redo.
   • skeletons/index.md — catalog of available sub-genre skeletons. For any slug whose row matches the request, open skeletons/<slug>/index.md and summarize what scripts/, entities/, and scenes/ could be cherry-picked into the new project. Treat the skeleton as a head start, not a constraint.
2. If gameplay mechanics are involved (movement, combat, enemies, bosses, HUD, hit feedback, death, pacing — basically anything beyond a static viewer), commission designer to fill the design-layer gaps before decomposing tasks and update GDD.md for user to review.
   • Whenever GDD changes — designer's handoff or your own edit — check it against the verbatim request before moving on:

     cat .vibegame/goal.md .vibegame/GDD.md > /tmp/gdd-fidelity.md
     vibegame vlm -t /tmp/gdd-fidelity.md -s "You compare a game design document against the user's verbatim request. List every requirement the GDD omits, weakens, or contradicts. Quote both sides. If none, reply exactly: NO DEVIATION."
     

   • Anything but NO DEVIATION goes back to designer with the quoted lines. This check is mandatory; your own read of the GDD does not replace it — you wrote the brief it was derived from.
3. If visual elements are involved:
   • If user does not provide concept/reference image, commission artist to produce a project reference image (see artist.md → "Reference image"): a restrained single image showing the actual in-game look from the GDD (not concept art / mood board / poster), containing only the key elements that belong in the same real gameplay view. Later asset tasks use this image as the reference so generated player, enemy, UI, prop, and scene assets match the approved elements.
   • Establish the GDD before commissioning the reference image. Artist may develop visual details and UI layouts left unspecified by the GDD, but must preserve its established gameplay rules and requirements.
   • If the generated reference image contradicts or extends the GDD, the lead must reconcile them before execution: either ask artist to redraw the reference to match the GDD, or update the GDD to explicitly accept UI / HUD / layout / prop choices introduced by the reference image.
   • Use this reference image to validate visual direction with the user. Iterate until approved.
   • DO NOT specify frame counts or animation details - that is artist's responsibility
4. Break the goal into macro stages. Each stage should have:
   • The project state reached when the stage completes
   • How that stage outcome can be tested
   • Which earlier stages must finish first
   • Tasks that can launch together once the stage is ready
5. Within each stage, choose independent tasks that can run in parallel. For each task:
   • Single bounded deliverable with clear ownership
   • Clear acceptance criteria
   • No hidden dependency on another task in the same stage
   • If proposed sibling tasks share an unstable core interface, state model, scene structure, or core files, merge them into one task
6. Fill in .vibegame/goal.md: ## Task Breakdown (stage plan and tasks) and ## Done When (goal-specific, checkable outcomes — not "the game runs"). Never edit ## User Input; when the user overrides an earlier requirement, express it in ## Done When.
7. Give the files for user to review. Wait for explicit user approval before execution. The user may direct you to merge / split / drop tasks at this stage — accept their direction. Task scope is the user's decision, not yours.
