What this skill does
deepclaude Skill by ara.so — Daily 2026 Skills collection. deepclaude routes Claude Code's API calls to DeepSeek V4 Pro, OpenRouter, Fireworks AI, or any Anthropic-compatible backend — keeping the full Claude Code UX (file editing, bash, subagents, git) while cutting costs by up to 17x. How it works Claude Code reads specific environment variables to determine its API endpoint and model names. deepclaude sets these per-session (not permanently), launches Claude Code, then restores originals on exit. Key environment variables Claude Code uses: Variable Purpose --- --- ANTHROPICBASEURL API endpoint override ANTHROPICAUTHTOKEN API key for the backend ANTHROPICDEFAULTOPUSMODEL Model for Opus-tier tasks ANTHROPICDEFAULTSONNETMODEL Model for Sonnet-tier tasks ANTHROPICDEFAULTHAIKUMODEL Model for Haiku-tier / subagents CLAUDECODESUBAGENTMODEL Model for spawned subagents Installation Prerequisites Claude Code CLI installed (npm install -g @anthropic-ai/claude-code) Node.js 18+ (for the proxy server) API key for at least one backend 1.
