Turtle d1e22a7e24 feat(preset): declare Agent compositions in profile YAML (#4569)
* feat(preset): declare Agent compositions in profile YAML

* fix(preset): share scope binding cleanup and refresh module graph

* fix(preset): use host syntax colors in the YAML editor

* fix(preset): write new profile declarations as block YAML

* fix(preset): align eager activation with browser and worker surfaces

* fix(ui-agent-preset): retain the existing preset card layout

* fix(preset): keep rows waiting for a Host service mounted and re-audit after settlement

A preset row whose Host provider was still activating at declaration time
was reported as waiting for a missing service, and the registry recorded the
definition as broken for the rest of the process. Split the mount audit into
failed and pending rows: failures and root-realm leaks still reject the
mount, while pending rows stay mounted and every read and binding re-audits
them after the Host Loader tree settles.

Remove the accidental self-dependency of @deepseek-ai/dsh-web-app and its
lockfile self-link. Archive the copy-only preset authoring note, which the
declarative-preset note fully supersedes, and update the ralph note's
restore recipe to the profile-patch mechanism.

* chore(lint): re-key and prune the unknown-cast baseline after the master merge

* refactor(web-app): ship each Agent preset as its own bundle patch file

`dsh.bundle.patch` accepts an ordered file list, so the four shipped preset
declarations move out of the 1000-line web patch into
`presets/<id>.patch.yml`, one insert per file, applied after the host patch.
The host patch keeps the preset registry row. Gates and test scaffolds that
read the web layer resolve every patch file through `bundlePatchPaths`
instead of one hardcoded path.

* refactor(preset): drop the save notice injected into live Agents

The notice duplicated the save result the Web editor already shows, and
after the producer-owned message sources it would have needed its own
persisted source kind. Saving now only persists and reports the activation
diagnostic; the persistence catalog is unchanged from master.

* docs: regenerate the module graph after dropping the registry's llm dependency

* test(ui-agent-preset): cover the guide dialog's keyboard handling on the declarative section

* fix(preset): address the remaining review comments

Apply the lowercase id rule only when creating a declaration, so presets
declared with other ids stay editable. Export `isBuiltInPreset` from the
display fold and key the client card groups on it. Remove the dead `error`
and `retry` locale keys, the JSDoc orphaned by the `trust` removal, the
`trust` fields in the plugin-inventory test fixtures, and the stale
`dsh-agent-presets` package name in comments and READMEs.

* refactor(preset): make the Web preset page view-and-select only

Remove the child-plugin YAML editor, the `agent_preset` tool and the
registry's read/save Remote methods. Presets are declared and changed only by
bundle patches; the settings page keeps the roster, the new-task default and
the mode help, and its question icon explains that and offers to start a
Creator-mode task. The `editing-cordis-compositions` skill and the Creator
persona describe the bundle-based path, and the authored skill-load Session
and Web snapshots are refreshed for it.

* docs(skill): make the composition skill self-sufficient for preset authoring

State where the shipped declarations live, list every declaration field,
inline a complete minimal bundle and an override example, and name the
verification calls, so Creator mode no longer reads DSH package sources to
infer the format. Refresh the authored skill-load Session for the new text.

* test(tools): drop the removed agent_preset tool from the catalog expectation

subagent/ — subagent capability family

English | 中文

Summary

The subagent package family lets an agent delegate a task to a child, continue the child's work, and discover every child it created. Choose a fresh in-process child for isolated work, a history-seeded in-process child when prior conversation matters, or an out-of-process child backed by ACP, Codex, Claude Code, or another Harness runtime. Model-facing tools also let agents message adjacent agents, interrupt work, and list child status. Each child remains visible to its parent whether it is running or stored; the package READMEs document provider-specific setup and limits.
