emitWorkflowEvent's catch rendered the thrown value with a bare String(error), which itself throws when the value's toString / Symbol.toPrimitive throws — breaking the documented containment guarantee: such a listener could fail the run mid-emit, starve later listeners, and turn the detached workflow/end settle hook into an unhandled rejection. Render through a local total fallback instead (String in a try, a fixed label when even coercion throws); local because the seam sits below every engine and cannot import an engine's renderer. Regression: a listener throwing a coercion-trap value — the emit does not propagate and later listeners still run.
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.
