The Claude Code package is also an optional Profile Bundle. Install it with dsh plugin --profile <name> add @deepseek-ai/dsh-subagent-claude-code, then restart that Profile; the package registers only its dormant Host provider. To grant the tool, copy a complete Agent Preset, remove disabled from the matching tool row, and start a new Session. Removing the package withdraws that provider on the next Profile start. The Codex package remains an explicitly mounted Host plugin and uses a host codex from PATH.

See the decisions for the capability family, continuable children, and control tools.
