lintianle f38111e5ca fix: handle MCP transport disconnect and concurrent tool re-sync

- Add client.onclose handler to unregister tools when the MCP server
  disconnects (crash or intentional close)
- Replace bare `let disposers` with a shared mutable state object so the
  effect disposer and notification handler always reference the current
  generation
- Serialize tools/list_changed resyncs with latest-wins coalescing
  (syncing + pendingResync flags) to prevent concurrent races

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.
