A pi extension for DeepSeek V4 Pro that narrows the agent's first request to a minimal tool catalog (shell and read only), then restores the full catalog after the session records its first durable tool call. It also rewrites the harness-injected system prompt to the DSH minimal-mode persona for the whole session.
