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.

Group	Role	Release expectation

spill/	Spill capability family: storage seam, local impl, tool-result spill policy	Product — stable surface
todo/	The model-facing todo_write tool	Product — stable surface
plan/	Plan collaboration state with a direct entry command and reviewed exit	Product — stable surface
timeout/	Tool-call timeout policy: the tools/execute deadline enforcer	Product — stable surface
guard/	Loop-hygiene guards: advisory repeat-call reminders	Product — stable surface
cordis/	Self-referential runtime toolset: inspect the live runtime's plugins and services, mount/unmount model-written plugins (design)	Product — stable surface
hooks/	Hook bridges + the shared Claude Code / Codex wire-protocol library	Product — stable surface
session-persistence/	Persistence seam + JSONL/SQLite backends	Product — stable surface
session-projection/	Projection seam: domain fold units serve whole values	Product — stable surface
session-query/	Session retrieval family: logical corpus, bounded reads, lineage, event relationships, semantic filtering, and SQLite full-text search	Product — stable surface
session-title/	Log-backed session titles: fallback service and opt-in LLM providers	Product — stable surface
telemetry/	Session reporting: capture/redact seam, OTel backend	Product — stable surface
storage/	Non-session storage hub + backends + domain form	Product — stable surface
workspace/	Workspace entity	Product — stable surface
sdk/	Project SDK tooling	Product — stable surface
acp/	Automation-only Agent Client Protocol server	Product — stable surface
ui/	TUI and JSON-RPC integrations, approval/interaction seams, ask-user tool	Product — stable surface
host/	Web-GUI host half: API gateway + HTTP route server	Product — stable surface
client/	Web-GUI browser half: shell, wire, object services, slots, ui-* plugins	Product — stable surface
examples/	Demo bundles (agent-spine + TUI/CLI/ACP/JSON-RPC bins) leaves load	Support — example infra
support/	Support infrastructure (testkits, invariants, replay, Loader smokes)	Support — lower compatibility expectations
util/	Low-level zero-dependency utilities shared across groups (Branded<B>, Harness home/path helpers, timeout, retention)	Support — small, stable, harness-dep-free

Groups distinguish product API from support infrastructure. New packages join an existing group; a new group updates its 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.
