+```
+
+
+## Compatibility
+
+Existing records remain valid. The additive working-directory source kind is attribution only; the declared source policy preserves unknown attribution without interpreting it. The Session format remains unchanged.
+
+
+## Verification
+
+pnpm exec vitest run packages/session/working-directory/tests packages/shell/tool-bash/tests/tools.spec.ts packages/shell/tool-pwsh/tests/tools.spec.ts packages/subagent/subagent-in-process-driver/tests/schedule-tools.spec.ts: 4 files and 203 tests passed.
+
+
+## Dev Note
+
+None.

Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
Start independent subagent delegations together in one assistant message and continue useful work while they run.
