SubagentStartRequest gains persona (capability-gated like toolFilter); the
in-process driver composes the child's scoped world in the factory's setup
window — persona as a scoped shadowing deployment:persona section,
toolFilter as a scoped tools.restrict() (loud unknown-name validation),
outputSchema as the scoped structured runtime. spawn/fork now advertise
every start-time capability; ACP stays all-false. A parent-scope teardown
effect links each child to its parent through the memoized handle, so a
disposed parent reaches its whole subtree even if the delegating tool's
finally never runs; subagent/start|end dispatch in the delegating parent's
scope.
structured.ts loses the placeholder schema, the final-assembly swap/strip,
the refcounted root runtime, and the WeakMap state: each child registers
its OWN capture tool (real schema), instruction section, and enforcement
listeners on child.ctx, riding the child's fiber. The commit listener is
call-keyed (a stale stage from a short-circuited post-execute chain is
dropped, never promoted on a later call), and one scoped prepend re-assert
listener preserves the final-assembly guarantee against a stripping global
listener.
tool-subagent gains persona/toolFilter/maxDepth passthrough config —
deny-listing the delegation tool (or maxDepth) is how a deployment bounds
recursion; the omitted-toolFilter schema key is forced absent (a
materialized {} would mean an empty allow-list, i.e. deny-everything).
@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.
