Three proposal documents, numbered in dependency order: - RFC 009: an abstract, append-only, event-based SessionPersistence service over the existing SessionEvent log (no parallel persisted type), a JSONL impl, a SessionMeta header seam, and an async AgentLoop.resume path. Design informed by Codex/Claude Code/ opencode/pi. Core design point; unblocks resume + ACP session/load. - RFC 010: ACP (Agent Client Protocol) support as a dsh-acp client-driver plugin on @agentclientprotocol/sdk, mapping ACP onto the agent/* events and the tools/execute permission seam. Builds on 009 for session/load; single active session. - RFC 011: multiplex concurrent ACP sessions over one connection (bridge-layer change; downstream of 010).
DeepSeek Harness
Monorepo for the DeepSeek Harness group.
Projects
- DeepSeek Code — DeepSeek's coding agent product.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
yarn install
yarn test # vitest
yarn demo:echo # runnable echo-agent example (no API key needed)
yarn demo:coding # the real DeepSeek coding agent (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 before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
