xiaobbl/dsh-opencode-go-model-list

xiaobbl/dsh-opencode-go-model-list is a native DSH plugin that extends the built-in opencode-go provider model catalog in DeepSeek Harness. It adds new models that are currently offered by OpenCode Go but not included in the default DSH snapshot. You can install it via the standard dsh plugin command, either by linking the local project folder or adding a packed local file. The package declares the required dsh.bundle.patch field, so a single command handles dependency installation, node_modules setup, and bundle registration automatically. It operates by injecting new models directly into DSH's existing catalog system.

This plugin addresses common issues users face when manually adding new OpenCode Go models to DSH. Editing the full provider models configuration replaces the entire existing catalog, requiring users to re-add all existing model entries just to add one new model. Using model overrides only works for existing model IDs and cannot add brand new models that are not already in the catalog. Creating a custom provider route breaks compatibility with existing DSH plugins for session management and cost tracking, so those plugins will not recognize the new route or any models added to it.

The plugin is released under the open source MIT license, and has no extra external dependencies beyond what DSH already provides. It fetches the latest model list from the public OpenCode API and pulls model metadata like context limits and pricing from models.dev, by default refreshing every six hours. It caches the resulting catalog in DSH's cache directory, so if network access fails on first run or later, DSH will fall back to the last cached version or the original shipped catalog. Shipped models are never overwritten unless you explicitly enable the updateExisting configuration option, and uninstalling the plugin fully restores the original catalog.
