$DSH_HOME/config.yaml was an implicit composition layer: if the file existed, every launch applied an arbitrary Loader patch graph over the shipped tree, kept live by a dedicated HMR watcher. Three costs came from the implicitness, not the capability. A patch replaces its target row's whole config, so a file written months ago pins that row to the field set it knew and every default the shipped tree later adds silently stops applying. It competed with the typed settings namespaces llm-deepseek and llm-pi-ai already register, so which one wins was a function of layer order rather than meaning. And the explicit escape hatch it was supposedly redundant with did not exist on every surface: dsh -p, dsh meta, and dsh upgrade all rejected --config, so for them the implicit file was the only composition route at all. Complete the explicit layer first: --config and --config-replace now work on every booting surface. A headless --config-replace tree must still mount a webserver row, because that surface reaches its own agent over the same HTTP gateway the browser uses; AppCLIEntry names that contract in the failure instead of reporting a bare missing service. Then delete the implicit one. PERSONAL_CONFIG_FILENAME, loadPersonalPatches, watchPersonalPatches, and the config-only HMR row mounted for it are gone; a file left at that path is inert, and --dump-config no longer reads the Harness home. --config therefore stops *replacing* the personal overlay and simply *is* the user overlay. No migration: a user who wants the old behavior names the same file (dsh --config ~/.dsh/config.yaml), which a shell alias makes permanent.
Packages
English | 中文
Packages use the @deepseek-ai/dsh-* scope. Each is a Cordis Service subclass or function plugin; contributions use 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.
