Codex-native CLI for AI-assisted game development, scaffolding local projects with studio roles, bounded prompts, and hard-failing validation.
This repository also configures its own agents. See what codex-game-studio tells them →

Skill Claude Code
Use for onboard tasks that orient a new contributor or agent to project state, file layout, stage, risks, and next work; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for patch notes tasks that write player-facing patch notes with fixes, known issues, balance changes, and verification caveats; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for perf profile tasks that profile frame time, memory, loading, assets, rendering, scripting, and platform constraints; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for playtest report tasks that capture player observations, comprehension, friction, loop completion, bugs, quotes, and design implications; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for project stage detect tasks that detect whether the project is in concept, design, technical setup, pre-production, production, polish, or release; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for propagate design change tasks that trace a design change through systems, docs, tasks, tests, content, and release risk; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude CodeCodex
Use for prototype tasks that build or plan a throwaway concept prototype around a falsifiable design hypothesis and cleanup boundary; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for qa plan tasks that plan focused QA coverage across features, risks, platforms, devices, regressions, and acceptance criteria; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for quick design tasks that draft a constrained design slice fast while preserving pillars, assumptions, and open questions; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for regression suite tasks that define or run regression coverage for changed systems, prior bugs, critical paths, and release blockers; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude CodeCodex
Use for release checklist tasks that check build, packaging, store, QA, localization, accessibility, rollback, and ship/no-ship readiness; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for retrospective tasks that facilitate a retrospective with what worked, what failed, root causes, actions, and owner follow-up; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for reverse document tasks that create design or technical documentation from existing implementation without inventing unverified behavior; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for review all gdds tasks that cross-check all GDDs for consistency, missing systems, dependency conflicts, and production readiness; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for scope check tasks that assess whether requested work fits the milestone and propose cuts, deferrals, or safer slices; produce verification evidence, changed or proposed files, and handoff boundaries.
Skill Claude Code
Use for security audit tasks that audit secrets, network surfaces, auth, saves, platform APIs, dependencies, and exploit risks; produce verification evidence, changed or proposed files, and handoff boundaries.
