dsh-seed-depth: Seeding Depth

`dsh-seed-depth` is a DeepSeek Harness (DSH) plugin designed to address the determination of the “seed depth” parameter in agent development or data processing. Maintained by user uckkk and licensed under the MIT License, it primarily provides the `seed_depth` tool, which returns explicit seed depth recommendations based on the provided parameters. The plugin is implemented in pure Node and has no network dependencies, while requiring `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`. Once installed, it can be invoked and used in DSH sessions.
