Fast Rust launcher for DeepSeek Harness, with clear Claude Code/Codex migration, model setup and lightweight local tools
rdsh — a fast, safe Rust launcher for dsh
An independent community project; not an official DeepSeek or DeepSeek Harness project.
rdsh is a drop-in fast path for dsh (the DeepSeek Harness CLI). Instead of rewriting everything, it ports only the hot paths to Rust and delegates conversations and model runs to the original dsh binary. Arguments you already use keep working as-is.
- Fast startup, small footprint. --version replies in about 0.90 ms with about 2.9 MB peak RSS on Linux x8664 (original dsh: about 88 ms and 66 MB). Short-CLI numbers only; they do not describe the resident Desktop app or model calls. - Drop-in compatible. Anything that is not an rdsh-native subcommand is passed to the original binary unchanged, so existing scripts keep running. - Useful native commands. Token estimates, search, compaction, session listing, and health checks run without starting Node. - Safe by default. Read paths never write, server features stay off until enabled, and agent tools run under mandatory isolation on supported Linux.
See the usage and recovery flow, settings, and architecture. Delegated conversations need the original DSH runtime.
Item Detail --- --- OS Linux, macOS, WSL, Windows (native). Agent isolation needs Linux x8664 + bubblewrap + prlimit. DSH runtime Original dsh for conversations. Audited versions: 0.2.0-rc.2, 0.2.1-alpha.1. Rust 1.85+ (source builds only). Prebuilt binaries need no Rust. Optional Node.js 22+ for the Node.js dashboard; SearXNG for search-web; zstd CLI for exact compressed token sizes.
