Sandbox & safety

8 packages
  • Sandbox-consuming implementation of the DeepSeek Harness bash executor seam (confines every command via ctx.sandbox, reports denial/enforcement result facts)

  • Sandbox-enforcing implementation of the DeepSeek Harness filesystem seam: fences write/edit by the per-call sandbox mode (read-only denies mutation, workspace-write contains it to the workspace + temp roots) while reads pass through

  • Sandbox-consuming implementation of the DeepSeek Harness PowerShell executor seam (confines every command via ctx.sandbox, reports denial/enforcement result facts)

  • Abstract process-sandbox seam (ctx.sandbox) for the DeepSeek Harness: same-world confinement vocabulary and the SandboxProvider contract

  • Local process-sandbox backends for the DeepSeek Harness sandbox seam: bwrap, the npm-distributed landlock-run launcher, macOS Seatbelt, or the Windows ACL restricted-token runner — functionally probed, fail-closed

  • Per-call sandbox policy resolver and current model context: deployment fallbacks plus each session's mode and workspace root, shared by every enforcing capability family

  • Windows ACL write-restriction sandbox backend (restricted-token spawn with orphan-SID write allowlist) for the DeepSeek Harness sandbox seam

  • Tool-independent managed DSH_* shell environment registry

Storage & files

13 packages
  • Durable immutable attachment storage seam for the DeepSeek Harness

  • Private content-addressed DSH_HOME attachment storage

  • Abstract filesystem capability seam (ctx.fs) for the DeepSeek Harness — vocabulary types, the FileSystem service (text IO + optional version-guarded atomic mutations), and the fs/* policy event vocabulary

  • E2B filesystem implementation for DeepSeek Harness

  • Local-filesystem implementation of the DeepSeek Harness filesystem seam (ctx.fs)

  • File-context policy plugin for the DeepSeek Harness — observed-state, read-before-edit, and version-guarded write/edit added over the ctx.fs provider seam through the fs/* event gate (no service API)

  • Abstract spill storage seam (ctx.spillStore) for the DeepSeek Harness — save oversized tool text and return a retrieval locator

  • Local-filesystem implementation of the DeepSeek Harness spill storage seam (private session-scoped files)

  • Tool-result spill policy for the DeepSeek Harness — replaces oversized plain-text tool results with a retained preview plus a spill-file path (no service surface)

  • Storage hub (ctx.storage): named backend registry plus mounted data-form facilities for the DeepSeek Harness

  • Domain data form (ctx.storage.domain): schema-validated, event-emitting KV domains over storage backends for the DeepSeek Harness

  • JSON file KV storage backend for the DeepSeek Harness storage hub

  • SQLite storage backend (kv facet) for the DeepSeek Harness storage hub

Integrations

9 packages
  • Automation-only Agent Client Protocol server for driving DeepSeek Harness agents over JSON-RPC stdio

  • The dsh ACP profile bundle: automation-only JSON-RPC stdio and process lifecycle over dsh-base

  • ACP automation server app: agent spine + JSONL persistence + ACP transport, with a JSON-RPC stdio bin

  • ACP test kit: shared subprocess launcher, snapshot scenario harness, expected-output normalizers, and suite factory

  • Bridge plugin: run a Claude Code hooks.json / settings hook config on the DeepSeek Harness interception seams

  • Bridge plugin: run a Codex hooks.json hook config on the DeepSeek Harness interception seams

  • Abstract LSP capability seam (ctx.lsp) for the DeepSeek Harness — language-server provider registry keyed by branded id and extension mapping, order-independent per-query selection, normalized definition/references/implementation/hover requests and result

  • Generic stdio language-server provider for the DeepSeek Harness LSP capability seam (ctx.lsp) — spawns configured servers, translates JSON-RPC, and serves transient-open goToDefinition/findReferences/goToImplementation/hover queries in the host filesystem

  • MCP client bridge: connects to MCP servers and registers their tools on ctx.tools

SDK & entry points

9 packages
  • Shared boot glue for the app bins: .env loading, fail-loud Loader guards, snapshot-aware config resolution, and the Loader boot sequence

  • Immutable command-line handoff from a dsh launcher to any app plugin that injects cmdlineArgs

  • The dsh one-shot bundle: a direct core Agent/Session runner over dsh-base with no Host, HTTP, or browser layer

  • The dsh SDK profile bundle: stdio JSON-RPC serving and process lifecycle over dsh-base

  • TypeScript client SDK for driving a DeepSeek Harness runtime subprocess over stdio JSON-RPC: the DeepSeekHarness high-level turns API and the lower-level HarnessClient

  • Bin that boots an external Cordis config for the stdio JSON-RPC SDK runtime

  • Stdio JSON-RPC server plugin for out-of-process DeepSeek Harness SDK clients

  • The standalone minimal SDK profile bundle: JSON-RPC, one DeepSeek adapter, persistent shell, editor, and JSONL sessions

  • Shared wire protocol for the DeepSeek Harness SDK runtime: the newline-delimited JSON-RPC stdio transport and the named request, result, and notification types spoken between the runtime server and SDK clients

DeepSeek Harness remains in developer preview and is still being tested by developers building agent harnesses. Its core plugins and APIs will continue to evolve. We look forward to exploring the limits of intelligence with developers worldwide using open-source infrastructure that is reusable and composable.
