Tianyi Cui f256f3961d feat(system-prompt): prompt variables, persona-as-section, tool-guidance ownership
One principle: every fact in the assembled prompt has exactly one owner.

- dsh-system-prompt: merge-extensible AssembleContext on assemble();
  a variable(name, provider) registry; {{name}} interpolation in
  renderPrompt, strict (unknown/valueless/malformed references throw);
  duplicate section and variable names rejected; assembly carries
  resolved section text + variables through the assemble waterfall.
- dsh-agent declares AssembleContext.agent; dsh-agent-loop registers
  the agent:persona section (order 0 - identity renders before tool
  guidance) and the model/cwd variables, and drops its string join:
  renderPrompt(assembly) IS the full prompt.
- Tool guidance moves to its owners: descriptions carry per-tool
  semantics; sections only cross-call habits (tool:bash exit-code
  habit at order 105; read's not-shell nudge). todo/subagent need no
  section - their descriptions already carry the contract.
- SubagentProvider.inheritsParentContext (spawn/acp false, fork true);
  dsh-tool-subagent derives truthful per-provider wording and resolves
  the provider at load (backend must be listed first).
- Example personas shrink to identity + behavior with {{model}} (and
  {{cwd}} in the ACP tree); the welcome banner stops enumerating tools.

@deepseek-ai/dsh-subagent-mock

A scripted SubagentProvider for testing the subagent seam without a model or a real child agent — the subagent analog of dsh-llm-replay.

It lets a test drive ctx.subagents and the model-facing dsh-tool-subagent through the real cordis Loader / export path, exercising provider registration, start-time capability validation, the run lifecycle (result / cancel / dispose), and the structured-output branch — all deterministically and keylessly.

Usage

Load it as a plugin (functional shape: name/inject/Config/apply, no default). Config (all optional):

Key Default Meaning
name mock Registry name to register the provider under.
reply mock subagent reply The scripted child's final answer text.
stopReason completed The stop reason result settles with.
capabilities all true Which start-time capabilities (outputSchema/depthLimit/toolFilter) the provider advertises.
inheritsParentContext false The context contract to declare; true exercises the fork-shaped tool wording in consumer tests.
structured { reply } Structured value surfaced when a request carries an outputSchema and the capability is on.

A cancel() issued before result settles flips the stop reason to aborted, so the cancellation path is observable.
