dsh-i-have-adhd: ADHD-Friendly Output Shaping Plugin for DeepSeek Harness

`dsh-i-have-adhd` is a DeepSeek Harness plugin designed to reshape model output formatting, eliminate redundancy, and improve information scanning efficiency. By injecting system prompts, it enforces “action-first” structured responses. It provides the `adhd_on/off/status` tools and file markers, supporting persistent state and real-time toggling. The plugin’s rules have lower priority than DSH’s own rules; once enabled, model responses will directly include numbered steps, time estimates, and confirmation steps, making it suitable for efficiency-driven development.
