What is DeepSeek Harness Minimal Mode?
The official DeepSeek Harness Web UI describes Minimal Mode as a two-tool coding agent with persistent bash and str_replace_editor.
The shipped Minimal preset uses a complete fixed persona, suppresses runtime-context snapshots and does not include context compaction.
Which tools are in Minimal Mode?
Persistent bash
@deepseek-ai/dsh-tool-bash-persistent provides a persistent shell across calls.
str_replace_editor
@deepseek-ai/dsh-tool-str-replace-editor provides the file-editing surface used by the preset.
The shipped Minimal composition does not load @deepseek-ai/dsh-tool-web. Its persistent Bash tool description also states that the shell does not have internet access.
How Minimal Mode selection works
Agent presets are selected for a new session. The official preset UI documentation says a running session keeps the preset it began with; changing the default applies to later sessions rather than switching an active session.
Minimal Mode vs Standard Mode
Minimal Mode intentionally exposes only the persistent shell and editor composition. Standard Mode is the broader built-in coding agent with file editing, shell, file and web search, skills, planning, goals, subagents and workflows.
