surface.replaceGeneration gets its direct-access test (the getter folds a pending delta itself, not only via a nodes read); the reconstruction theorem drives maxTokens and stop through the config waterfall; the compact-basic envelope drops a dead conditional — config.maxTokens is required and validated positive, so this backend's envelope always carries the cap (the return type's optionality exists for overriding subclasses).
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.
