Packages
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 |
|---|---|---|
core/ |
Product API spine: session, system-prompt, tools, agent, and the concrete loop | Product — stable surface |
llm/ |
LLM capability family: the abstract service + provider adapters | Product — stable surface |
bash/ |
Bash capability family: the executor seam, a local impl, and the model-facing tool | Product — stable surface |
code-runtime/ |
Code-execution capability family: the abstract runtime seam for model-written programs + a worker-thread backend | Product — stable surface |
sandbox/ |
Process-confinement seam; bwrap/Landlock/Seatbelt backends | Product — stable surface |
fs/ |
Filesystem capability family: the abstract seam, a local impl, the model-facing file tools, and the bash-backed discovery tools | Product — stable surface |
skill/ |
Skill capability family: the provider registry, local provider, and model-facing catalog/loader | Product — stable surface |
compact/ |
Compaction capability family: the abstract seam + a basic backend (tool deferred) | Product — stable surface |
context/ |
Model-visible request context, including workspace instructions and time context | Product — stable surface |
subagent/ |
Subagent capability family: the provider-registry seam and the model-facing delegation tool | Product — stable surface |
tasks/ |
Generic background-task runtime and model-facing task_* control tools |
Product — stable surface |
workflow/ |
Workflow capability family: the script-engine seam, the worker-thread engine, and the model-facing workflow tool |
Product — stable surface |
web/ |
Web capability family: the abstract seam, search/fetch provider impls, and the model-facing web tools | Product — stable surface |
spill/ |
Spill capability family: the storage seam, a local impl, and the tool-result spill policy | Product — stable surface |
todo/ |
Todo/planning family: the model-facing todo_write tool |
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 capability family: the seam + JSONL/SQLite backends | Product — stable surface |
session-query/ |
Session retrieval: logical corpus, bounded reads, lineage, and event relationships | Product — stable surface |
sdk/ |
Project SDK tooling | Product — stable surface |
ui/ |
Editor/client integration surfaces: ACP bridge, JSON-RPC SDK server, user-approval/user-interaction seams, ask-user tool | Product — stable surface |
examples/ |
Demo bundles (agent-spine + stdio/ACP/JSON-RPC bins) the leaves load | Support — example infra |
support/ |
Support infrastructure (testkits, invariants, replay, Loader smokes, subagent mock) | 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).
The rule it must obey: extension plugins depend on interfaces, never on the concrete loop. dsh-agent-loop is swappable — UI/hook/tool plugins keep working against the dsh-agent vocabulary if the loop is replaced. The sanctioned exception is a composition/bundle package like dsh-agent-spine-demo, whose whole job is to assemble the concrete spine: it depends on dsh-agent-loop (and the other concrete spine plugins) on purpose. The rule constrains plugins that EXTEND the system, not the bundle that COMPOSES it. A swappable capability splits into interface / implementation / consumer packages (the bash trio is the template — 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.
