A hooks bridge translating SubagentStart/SubagentStop needs to know WHICH kind of subagent ran and WHAT it produced — Claude Code's hooks carry subagent_type and the child's final message. Enrich the existing lifecycle emits to match, observe-only: - agentType: an optional caller-supplied subagent-kind label (CC's subagent_type), added to SubagentStartRequest and carried VERBATIM onto both subagent/start (SubagentRunInfo) and subagent/end (SubagentRunEndInfo). The seam never interprets it. dsh-tool-subagent threads it from a new optional Config.agentType, so a deployment exposing multiple subagent kinds (one tool load per kind) labels each. - lastAssistantMessage: the child's final output (SubagentResult.output), added to SubagentRunEndInfo on the settle path so an observer sees what the subagent produced without holding the run. Absent on the reject path (no result produced). Strictly observe-only: both events stay plain emits (subagent/end fires from a detached .then and awaits no listener). A control-flow subagent/end (awaited waterfall returning a decision) would need the emit→waterfall reshape, awaiting listeners before settling, and a provider resume capability — deferred to the background/steering redesign (FIXME(subagent-continuation) anchors it).

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.
pnpm install
pnpm run test # vitest
pnpm run demo:echo # runnable echo-agent example (no API key needed)
pnpm run 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.
