Claude Code and Codex Are Now DSH Subagents

DeepSeek Harness rc.7 and rc.8: Claude Code and Codex install as subagent Profile Bundles, Code mode becomes PTC mode, and the API gets 50% off-peak pricing.

Two releases this week: rc.7 (Aug 17) and rc.8 (Aug 19). The cadence is a release every two days. The headline: the competition is now a plugin.

Claude Code and Codex as subagents

Since rc.8, Claude Code and Codex install on demand as subagent Profile Bundles. Codex additionally gets a non-interactive permission mode and multiple named instances. rc.7 had already routed their subagent tasks through the Job Panel.

Concretely: dsh sits as the orchestrator and dispatches work to Claude Code or Codex the same way it dispatches to its own presets. "Everything is a plugin" now includes the rival agents.

So the adapter question runs in both directions — pick per task:

  • V4 inside Claude Code / Codex — DeepSeek's official adapters, no DSH involved.
  • Claude Code / Codex inside DSH — since rc.8, as Profile Bundles.

This changes the framing on our comparison pages: vs Claude Code, vs Codex.

Off-peak API pricing

Since August 16 the DeepSeek API bills by time of day. Peak is 01:00–04:00 and 06:00–10:00 UTC; every other hour is off-peak at half the peak rate.

| per 1M tokens | V4-Pro peak | V4-Pro off-peak | V4-Flash peak | V4-Flash off-peak | | --- | --- | --- | --- | --- | | Input, cache hit | $0.044 | $0.022 | $0.014 | $0.007 | | Input, cache miss | $1.32 | $0.66 | $0.44 | $0.22 | | Output | $3.96 | $1.98 | $1.32 | $0.66 |

Prices as of 2026-08-20, from the official pricing page. If your agents run unattended anyway, schedule the long jobs off-peak — it is a flat 2× difference.

The rest of rc.7 + rc.8

  • Code mode is now PTC mode — English preset name only, renamed in rc.7. Same preset: TypeScript orchestration of tool calls. Our modes page is updated.
  • low reasoning effort for DeepSeek models (rc.7). Default stays high.
  • Persistent PowerShell sessions on Windows PTY, on by default in the Minimal preset (rc.8).
  • Multimodal: configurable native image requests in the DeepSeek adapters, image input for /goal and /plan, file and session references in the @ menu (rc.8). Durable image attachments for MCP/ACP landed in rc.7.
  • Plugins can register their own settings cards (rc.7).
  • SQLite storage format changed in rc.8 — incompatible. Faster reads and forks, smaller files, but plan for your session store before upgrading.
  • Smaller dependency download, and dsh web now opens the browser by itself (rc.8).

Naming note for plugin authors

rc.8 also published brand guidelines: "DeepSeek Harness" is a registered trademark — don't put the full name in your project name. Use DSH, as the community dsh-plugin-* convention already does.
