How to run DeepSeek V4 Pro in Pi with the DSH mimic with Mixagents

Use the DSH Minimal persona on Pi's first DeepSeek V4 Pro request, then restore native Pi.

Short answer: Open packages/pi-dsh-mimic/README.zh-CN.md (or the English README in the same folder) and follow its install section; then install the pi-dsh-mimic package into Pi using the method in that install section; start a DeepSeek V4 Pro session in Pi and confirm the first request uses the DSH Minimal persona. All steps.

Reverse engineering. This package modifies the first request Pi sends to DeepSeek V4 Pro, so check the behavior against docs/advanced.zh-CN.md before relying on it.

Who it is forA developer who uses Pi with DeepSeek V4 Pro and wants the first request to follow a narrower persona and tool set.

The problemDefault Pi sends DeepSeek V4 Pro its full tool catalog from the first request, which the author's frozen Project2 test found less effective than the mimic path.

The outcomePi sends a modified first request with the DSH Minimal persona and two tools, then returns to the native request and full tool catalog after the first valid response.

What you need first

  • Codex with plugin support (the README says the broker is used from Codex 0.149.0 onward)
  • Accounts and credentials for each third-party provider you configure, billed separately from any ChatGPT or OpenAI subscription
  • Read SECURITY.md before install, since task content, file content and tool results may be sent to the configured provider

Steps

  1. Open packages/pi-dsh-mimic/README.zh-CN.md (or the English README in the same folder) and follow its install section
  2. Install the pi-dsh-mimic package into Pi using the method in that install section (inferred, check the README)
  3. Start a DeepSeek V4 Pro session in Pi and confirm the first request uses the DSH Minimal persona
  4. Read docs/project2-evidence.md to see the frozen Project2 scores before drawing conclusions
  5. Run the same task with default Pi and compare results on your own work

Prompt for your agent

Using the repo Utopia-V/mixagents, install the pi-dsh-mimic package into Pi and run one DeepSeek V4 Pro task on <task description>. Return the output and a short comparison with default Pi on the same task. Verify that the first request used the DSH Minimal persona and that native Pi tools were restored after the first valid response.

Caveat. The README says the Project2 scores (92 default, 96 to 98 in four repeats) come from one frozen task and do not represent a general benchmark.
