Chinesezjc 8f06c561ee docs(code-runtime): state the maxWallMs upper bound in the public Config contract
The load-time range check rejects a maxWallMs above Node's maximum
setTimeout delay, but the constraint appeared only in the README design
section. Deployments reading the Config field JSDoc, the generated config
catalog, or the README config summary saw maxWallMs described as a
positive finite wall-clock ceiling, so an out-of-range value looked valid
until plugin load failed.

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
core/ Product API spine: sessions, prompts, tools, agent services, and the concrete loop Product — stable surface
goal/ Persisted same-session goal state and lifecycle Product — stable surface
llm/ LLM capability family: the abstract service + provider adapters Product — stable surface
bash/ Bash capability family: executor seam, local impl, model-facing tool Product — stable surface
pty/ Persistent PTY capability family: owner-scoped sessions, local implementation, and model-facing tools Product — stable surface
code-runtime/ Code-execution capability family: the 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: seam, local impl, model-facing file tools, bash-backed discovery tools Product — stable surface
lsp/ LSP capability family: seam, generic stdio provider, and the lsp tool 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, worker-thread engine, and model-facing workflow and fresh-agent ralph tools Product — stable surface
web/ Web capability family: seam, search/fetch provider impls, and the model-facing web tools Product — stable surface
spill/ Spill capability family: storage seam, local impl, tool-result spill policy Product — stable surface
todo/ Todo/planning family: 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 capability family: the seam + JSONL/SQLite backends 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, shared LLM policy, and opt-in providers 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/ Human/client integrations: TUI and JSON-RPC, approval/interaction seams, ask-user tool 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.
