>
> <https://github.com/deepseek-ai/deepseek-harness>
> commit 47f943859bef60e4160492346772ded9b24f765a
>
> That official `minimal` surface is:
>
> - the complete system prompt
>     `You are a helpful software engineer assistant.`
> - persistent `bash` (`@deepseek-ai/dsh-tool-bash-persistent`)
> - `str_replace_editor` (`@deepseek-ai/dsh-tool-str-replace-editor`)

> `dsh-anchored-standard` bootstrap (first request = official two-tool
> schema, later requests restore the host catalog after a durable
> promotion signal):
