Jayhe Gamemaker · DeepSeek Harness plugin

Key features

• Game development role subagents for DeepSeek Harness: a game-director pipeline built from three dedicated subagent providers plus two bundled agent presets.
• Planner/reviewer children are composed inside the child creation window via ctx.agentPresets.mount(childCtx, 'game-minimal'), which re-parents the child's scope to the preset's standing mount.
• The plugin consumes @deepseek-ai/dsh-subagent, @deepseek-ai/dsh-llm, and @deepseek-ai/dsh-session.
• The child therefore runs the real minimal composition — fixed persona, suppressed runtime context, two tools — instead of a persona + toolFilter approximation.
• Executor children join the parent preset, then their own scope declares presentAs('code'), making PTC mode hard: direct native calls are rejected, everything goes through run_code programs.
