A continuable background child (the default backgroundMode for both delegation tools) never received the parent session's explicit sandbox/approval overrides: materialization applied only child composition, so a danger-full-access parent produced workspace-write children whose every out-of-workspace operation raised an approval prompt. Move the one-shot driver's capture/append pair into the shared child-agent module (captureDelegatedPolicyOverrides / appendDelegatedPolicyOverrides) and call it from both paths: startContinuable captures before its first await, only fresh materialization appends the source-tagged events (after any fork seed), and a cold resume replays the persisted delegation events instead of re-capturing the parent. Adds the continuable inheritance unit suite, the ACP snapshot scenario subagent-continuable-inheritance (fails without the fix), the continuable policy-inheritance Agent Note, and the seam-level README contract, with bilingual counterparts. Fixes #1692
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/ |
Starts a fresh in-process child | registers on ctx.subagents |
subagent-fork/ |
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 |
