P0-2 artifacts-board.js: guard against LCS OOM on large blob diffs; fall back to note-based render when either side exceeds bound. P1-2 chat-side-drawer.js: flush pending turn on barge-in (user sends before assistant frame flushes), so drawer stays in sync with graph. P1-3 chat-refresh-throttle.js (new) + renderer.js: coalesce chat + graph refreshes into per-frame flush to prevent visual jitter under high-frequency intervention/refresh events. P1-4 artifacts.js: history entries bucket by sessionId; cross-session artifacts no longer bleed into the currently-open session's history rail. P1-5 rubric-fusion-model.js: seedOnce idempotency guard — repeated seed calls no longer duplicate rubric fixture rows (was surfacing as double-counted evolution nodes). test/code-bugs-batch.test.js (new, 9 assertions) covers all 5 fixes; test/artifact-evolution-board.test.js updated to align with bySession bucket shape. 9 files, +520/-43. Behavioral fixes only, no API surface change.
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.
