Restore the storage-domain medium the file-root design replaced: the cache opens the session_projcache domain (per-record layout — one document per session under the json backend root) and checkpoint writes land through the domain's write chain. Reads and writes now share ONE coherent state: cachedSnapshot reads synchronously from the domain's in-memory tables, and every write is durability-first-then-memory, so a read can never go around the write chain to the medium. The hand-rolled write chains, in-flight tracking, per-session file paths, owner-only file modes, and the sqlite no-path special case are gone; Config.root is removed and the domain's version stamp makes a checkpointRecord bump discard stale sessions per record instead of rejecting the whole medium. The async ripple of the old file read is reverted: api-proxy's listing column and subagent's cold identity read go back to synchronous cachedSnapshot.
subagent/ — subagent capability family
English | 中文
This family lets an agent delegate work to child agents. Multiple named providers may coexist in one context.
| Package | Role | ctx key |
|---|---|---|
subagent/ |
Defines provider registration, delegation, and continuation | ctx.subagents |
subagent-inprocess/ |
Provides the shared in-process run driver | — |
subagent-spawn-in-process/ |
Starts a fresh in-process child | registers on ctx.subagents |
subagent-fork-in-process/ |
Starts an in-process child from the parent's completed history | registers on ctx.subagents |
subagent-acp/ |
Starts an out-of-process child over ACP | registers on ctx.subagents |
subagent-codex/ |
Starts a real Codex app-server child | registers on ctx.subagents |
subagent-claude-code/ |
Starts a real Claude Code child through the official Claude Agent SDK | registers on ctx.subagents |
subagent-dsh-sdk/ |
Starts an out-of-process Harness child through the TypeScript SDK | registers on ctx.subagents |
tool-subagent/ |
Exposes delegation to the model | registers on ctx.tools |
tool-subagent-control/ |
Exposes child messaging and listing to the model | registers on ctx.tools |
tool-subagent-report/ |
Provides the child-to-parent report channel | registers in child scopes |
The Codex and Claude Code packages are independent optional Profile Bundles. Install either or both with dsh plugin --profile <name> add @deepseek-ai/dsh-subagent-codex @deepseek-ai/dsh-subagent-claude-code, then restart that Profile; each package registers only its dormant Host provider. To grant a tool, copy a complete Agent Preset, remove disabled from each matching tool row, and start a new Session. Removing one package withdraws only that provider and its private runtime closure on the next Profile start.
