clioo/dsh-claude-agent: Run your own Claude login in DeepSeek Harness

dsh-claude-agent adds a claude-agent model provider to DeepSeek Harness, adopting the opencode design to invoke the user's locally logged-in Claude binary via Anthropic's official Claude Agent SDK. The plugin does not read credentials or proxy requests; instead, model requests are initiated by the user's own subscription or gateway, ensuring compliance with Anthropic's current authentication and brand policies. In a stable state, the prompt cache hit rate exceeds 90% (with an overall hit rate of 95.4% based on the author's testing). The article introduces its design constraints, core features, runtime requirements (DSH 0.2.1+, Claude Code 2.1.248+), installation commands, configuration options, and caching mechanism, while also explaining applicable scenarios and precautions.
