Packages

English | 中文

Packages use the @deepseek-ai/dsh-* scope. Cordis Service subclasses and function plugins contribute through ctx.effect(), ctx.on(), or ctx.waterfall(). Authoring rules: package and root.

Hierarchy

Packages live at packages/<group>/<pkg>/; groups are containers, while names remain @deepseek-ai/dsh-<pkg>. Each group README is the canonical package/ctx-key map.

New packages join existing groups; new groups update their README and this table.

Dependencies

The dependency graph is generated: docs/module-graph.md (pnpm run gen-module-graph, freshness-gated in CI).

Extension plugins depend on interfaces, never the concrete loop. dsh-agent-loop is swappable; UI, hook, and tool plugins use dsh-agent. Composition bundles, including dsh-agent-spine-demo, may depend on spine plugins. Capabilities split into interface / implementation / consumer packages; see capability seams.

Package READMEs cover purpose, APIs, extension points, and Model Experience unless on the model-agnostic omission allowlist. They also carry ## Known Limitations and Deferred Work or use its allowlist.
