# Brainstorm Workflow

## Purpose

Generate bounded game ideas, feature variations, player fantasies, and tradeoff notes from the current project constraints.


## Inputs

- AGENTS.md
- .codex/studio.json
- .codex/workflows/brainstorm.md
- design/gdd.md

## Role

Creative Director (creative-director) owns this workflow.

## Taxonomy

Category: design-architecture
CCGS adaptation coverage:
- concept ideation
- creative option generation

CLI aliases:
- brainstorm

## Outputs

- Creative direction
- Scope decisions
- Experience pillars

## Validation

- Creative pillars are concrete
- Discipline guidance is aligned
- Scope trade-offs are named

## Phase Gates

- Confirm project state, owner role, write policy, and selected context.
- Name acceptance criteria before implementation or review work.
- Do not advance to handoff until evidence is recorded or a blocker is explicit.

## Required Artifacts

- Summary of the workflow result.
- Files, assets, tasks, or docs changed or proposed.
- Verification evidence and unresolved risks.

## Context Contract

- Load AGENTS.md, .codex/studio.json, this workflow, the primary agent, linked skills, and only task-relevant project files.
- Avoid broad context unless the user explicitly approves it.

## Output Contract

- Decision or change summary.
- Step-by-step work performed or planned.
- Evidence, blockers, warnings, and next owner.

## Stop Conditions

- Required project state, approval, target files, or verification path is missing.
- The task crosses into another role without an explicit handoff.
- The workflow would require generated prompt mirrors or hidden automation.

## Handoff

Report changed files, validation evidence, residual risks, and the next owner only when ownership changes.
