dsh-router-flash

dsh-router-flash addresses a problem that is easy to misdiagnose: by default, DeepSeek V4 Flash may reason shallowly, start work too early, and deliver inconsistent results. The issue is usually not a lack of model capability, but a missing agent guidance layer. This plugin packages the Flash-tuned guidance from the dsh-router-standard research into a standard DSH bundle, so the router-flash preset can be distributed to the local DSH environment and paired with opencode-go's deepseek-v4-flash model.

Its core strength is adding the right guidance. The preset injects five anchors—classification, review, anti-drift control, deep thinking, and decision closure—into the persona, helping Flash move from casual execution to structured planning: understand the task, lay out the steps, then deliver and verify. For complex builds, from-scratch development, and multi-step engineering work, this guidance can reduce careless starts and topic drift, turning Flash from merely usable into genuinely practical.

It is intended for users of DeepSeek Harness who run DeepSeek V4 Flash through opencode-go, as well as developers who want to use Flash for more serious coding, research, and construction workflows. After installation, the preset is synchronized into the local agent-presets directory, and the bundle supports Linux, macOS, and Windows. Non-Flash models are left on the original routing logic, so stronger models such as pro are not forced through Flash-specific guidance.
