dsh-v4-anchor

dsh-v4-anchor is a deliberately minimal DeepSeek Harness plugin designed to address potential inaction in DeepSeek V4 models during standard sessions due to overly complex system prompts. Existing experiments indicate that exposing a minimal RL-shaped surface in the first request—such as stripping runtime contexts and hiding AGENTS.md and Skill Catalog—can significantly boost tool call rates and practical task execution. This plugin replicates that mechanism: for qualifying DeepSeek V4 sessions, it automatically applies bootstrap filtering on the first request and restores full Standard capabilities after the first real tool call, while injecting a one-time reminder to ensure the model re-engages with the newly restored tools. It is not intended as a router or complex steering replacement but as a timely behavioral patch, helping researchers and developers easily test and validate the impact of RL-shaped bootstrap on model trajectories.
