enableRunInBackground: false removed the parameter from the advertised schema only — the arg validator deliberately allows undeclared keys, so a caller (or a model that has seen the parameter elsewhere) could still force run_in_background: true and start background work past the deployment's opt-out, in both tool-bash and tool-subagent. Both producers now refuse the forced key loud in execute(); tests pin the refusal (and that nothing spawns) alongside the untouched foreground path; the schema-omission-is-advertising rule is recorded in the runtime RFC and both READMEs.
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.
