Tianyi Cui 3f83a4ee96 review: the persona becomes the system-prompt plugin's deployment config
Review round 2 (tianyicui inline comments):

- dsh-system-prompt itself registers the harness:identity (-100) and
  deployment:persona (0) sections — they must survive a swapped loop
  plugin, so they leave dsh-agent-loop; the persona text is the plugin's
  own validated 'persona' config. The model/cwd variables STAY on the
  loop: runtime facts of the agents it drives.
- AgentOptions.systemPrompt is deleted with all its forwarding plumbing:
  the app configs' systemPrompt keys become 'persona' routed through
  dsh-agent-core (schema = z.intersect of the owners'), the ACP bridge
  and tool-subagent stop carrying persona configuration, and subagent
  children now render the deployment persona like every other agent.
- Example personas drop transport/interface trivia (ACP, CLI) — facts
  irrelevant to the model.
- Root CONTEXT.md removed (not idiomatic); its persona definition was
  wrong under the new ownership anyway.
- Docs, READMEs, the prompt-variables RFC, and generated catalogs
  updated; new loop test pins the assemble-waterfall escape valve
  (an emptied assembly sends NO system field).

Packages

Harness packages, all under the @deepseek-ai/dsh-* scope. Each package is a Cordis plugin (microkernel-style): it exports either a default Service subclass or a functional plugin, declares its ctx key/events through declaration merging, and exposes extension points through ctx.effect(), ctx.on(), and ctx.waterfall(). Authoring conventions: AGENTS.md (subtree) and the root AGENTS.md § Conventions.

Hierarchy

Packages are grouped by modular role at packages/<group>/<pkg>/. The group directory is a pure container (no package.json of its own); the package name stays @deepseek-ai/dsh-<pkg> regardless of group. Each group README is the canonical per-package map — package roles, ctx keys, and the product-vs-support split live there, next to the code.

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
fs/ Filesystem capability family: the abstract seam, a local impl, and the model-facing file tools Product — stable surface
compact/ Compaction capability family: the abstract seam + a basic backend (tool deferred) Product — stable surface
subagent/ Subagent capability family: the provider-registry seam and the model-facing delegation tool Product — stable surface
web/ Web capability family: the abstract seam, search/fetch provider impls, and the model-facing web tools Product — stable surface
todo/ Todo/planning family: the model-facing todo_write tool (whole-list task tracking on the session log) 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
ui/ Editor/client integration surfaces (the ACP bridge) + the app packages Product — stable surface
support/ Dev/test/example infrastructure (invariants, replay adapter, subagent mock) Support — lower compatibility expectations
util/ Low-level zero-dependency utilities shared across groups (the Branded<B> primitive) Support — small, stable, harness-dep-free

The split is the point: a package's group says whether it is part of the product API or support/test/example infrastructure, so release and removal decisions do not treat every package as an equal public contract. New packages join an existing group; adding a new top-level group is a deliberate act (extend the group READMEs and this table).

Dependencies

The inter-package 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-core, 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 — swapping the loop means shipping a different bundle, not rewiring every extension. A swappable capability splits into interface / implementation / consumer packages (the bash trio is the template — see capability seams).

Each package has its own README.md with purpose, service API, events, extension points, and deliberate non-goals (TODOs).
