Implements the LSP capability seam RFC as three packages: dsh-lsp (the ctx.lsp interface — provider registry by branded id + exclusive extension mapping, per-query order-independent selection, closed request/result vocabulary, LspError taxonomy), dsh-lsp-local (a generic stdio language-server provider — Content-Length JSON-RPC framing, per-(provider, workspace) process single-flight, transient didOpen/query/didClose, an abortable per-instance queue, UTF-16 negotiation, host-namespace source reads outside ctx.fs, and bounded shutdown/kill teardown), and dsh-tool-lsp (the model-facing lsp tool — four operations, one-based UTF-16 cursor conversion, workspace-grouped location rendering, hover capping, a required session workspace, and a timeout budget). Why: an agent had text search and file reads but no way to identify a program symbol — follow an alias, connect an interface to implementations, or read an inferred type — before changing code. Splitting model contract, seam, and local subprocess behavior keeps the four semantic queries stable across future remote or sandbox-native providers without leaking a JSON-RPC escape hatch.
DeepSeek Harness
English | 中文
The DeepSeek Harness SDK is a plugin-based SDK for building agent harnesses.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
pnpm install
pnpm run test # vitest
pnpm run demo:repl # REPL agent demo (needs DEEPSEEK_API_KEY)
pnpm run demo:acp # ACP server agent demo (needs DEEPSEEK_API_KEY)
For humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design and documentation graph index before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
