v0.1.0-alpha.1

[0.1.0-alpha.1] - 2026-08-16

Added

• Initial release: deepseek-harness-sdk is a pure-client Rust SDK that spawns the official DeepSeek Harness (DSH) runtime as a subprocess and speaks its stdio JSON-RPC 2.0 protocol.
• Protocol types with serde 1:1 wire mapping and a merge-extensible ContentBlock with unknown-content passthrough; line-framed stdio transport with skip-malformed-lines parity and an oversized-frame guard.
• Low-level HarnessClient: request dispatch with timeout abandonment, session-tree tracking from subagent.started edges, broadcast notifications, and an unconditional close ladder.
• High-level Python-parity API: DeepSeekHarness::start, Session::run, and RunResult with finish_reason and session_root.
• Typed errors across the API surface: Error::SdkProtocol, Error::JsonRpc (preserving code and data), and Error::RuntimeNotFound.
• Published to crates.io as 0.1.0-alpha.1 — install with cargo add deepseek-harness-sdk@0.1.0-alpha.1 (pre-release versions require an explicit version; a bare cargo add does not resolve to a pre-release).
• Bilingual installation-first READMEs (English / 中文) covering the quickstart, runtime acquisition routes, and platform support.
• Bring-your-own runtime (Plan A): the binary is resolved from Config::launch_args_override (full argv, verbatim), Config::runtime_bin, or the DSH_RUNTIME_BIN environment variable — the crate never downloads, bundles, or ships a runtime.
• Bundled default cordis.yml injection (byte-identical to the official default) when no DSH_CORDIS_CONFIG is set, plus environment injection of DSH_CWD, DSH_SESSION_ROOT, and model credentials.
• A missing runtime fails fast with Error::RuntimeNotFound, whose message names the acquisition routes and points to https://github.com/deepseek-ai/deepseek-harness.

Compatibility

• RunResult follows the Python SDK field set, including finish_reason and session_root — fields the TypeScript SDK's RunResult lacks.
• The wire protocol is pre-release: the runtime identifies as serverInfo 0.0.1 with a strict name check and no version negotiation.
• Consumes runtime builds for linux-x64, linux-arm64, and macos-arm64; there is no Windows support (upstream ships no Windows runtime builds).
• No mid-turn cancel or session-close RPC: Session::run waits until the root session reports idle.
