Implement recursive subagent workflow execution and collapsible nested runtime logs - #20
Conversation
… nested runtime logs This change introduces full-featured support for executing, rendering, and exporting/documenting nested Subagents (sub-workflows) within the browser-side AI workflow builder. It replaces static simulated schematic placeholders with recursive in-browser execution, adds a select dropdown for target workflow configurations in the node inspector, and renders subLogs and stateSnapshots within collapsible panels in the run logs drawer. Also updates Python and JavaScript code generation to include self-documenting nested workflow details (name, node count, edge count).

Unsanitized workflow names break both generators. Both generators interpolate subWf.name into a single-line comment. Workflow names are user-supplied through the workflows library. A name that contains a carriage return or line feed pushes the remainder onto a new line that carries no comment marker, which produces a syntax error in the exported file.

A shared helper keeps the two sites consistent, for example const oneLine = (s: string) => s.replace(/[\r\n]+/g, " ");.

Show the stored graph value when it does not match any workflow id.
The select only renders options for known workflow ids. If node.data.config.graph holds a value that is not in allWorkflows, the select renders blank while the config still holds the old value. This case is reachable today: the react-fallback node in the template-react template uses config: { graph: "deep_research" } (frontend/src/flow/workflows.ts), and no workflow has that id. The user sees an empty selector and cannot tell that a stale target is configured. The same applies to the excluded active workflow if it is already selected.
Add a fallback option for an unmatched current value.

Clone the resolved state object before you pass it to the sub-workflow.
Line 331 assigns pathVal directly as subInitialState. runFlow spreads initialState into a new object, so the top level is copied. Nested objects and arrays stay shared with the parent state. If a nested script or memory node mutates them, the change leaks back into the parent run.

🩺 Stability & Availability | 🔴 Critical | ⚡ Quick win
Add a recursion depth guard to nested subagent execution.
runNode now calls runFlow, and runFlow calls runNode. No limit bounds the nesting depth. maxSteps bounds the step count inside one flow only.
A cycle is reachable. The Inspector excludes only the currently active workflow from the dropdown (frontend/src/flow/Inspector.tsx, Line 82). A user can point workflow A at workflow B, then switch to B and point it at A. Loading either workflow and running it recurses without end. Because each level awaits, the tab consumes memory and stops responding instead of failing fast.
Thread a depth counter and a visited-workflow set through RunOptions, and stop when the limit is reached.

depth?: number;

Propagate sub-workflow failures to the parent flow.
runFlow records node errors inside the returned logs and resolves normally. The subagent case ignores that. It returns a successful result even when every nested step failed. The parent then follows the on_success or next edge, and the run reports success.
Inspect subLogs for errors and throw, so the parent routes to on_error.

The snapshot key format breaks "Expand Snapshots".
LogItemRow reads expandedSnapshots with the key ${log.step}-${log.nodeId}-${depth}. handleLogsExpandAll (Line 1287) still writes the key ${l.step}-${l.nodeId} without the depth suffix. The two formats never match, so the "Expand Snapshots" button has no visible effect.
The key is also ambiguous for nested logs. Two sibling subagent nodes that run the same sub-workflow produce the same step, nodeId, and depth, so their snapshots toggle together. Pass a parent-scoped key prefix to make the key unique.
Align both sites on one key format.

This test passes while the nested workflow fails.
runFlow is called with gateways: []. The template-react sub-workflow contains the llm node react_loop. runNode throws "No gateway available — open ⚙ gateways and add one" for that node. runFlow records the error in the log and halts the sub-flow, because template-react has no on_error edge from react-llm.
The test asserts only subLogs[0], so it still passes. It therefore does not prove that recursive execution completes. It also becomes brittle: if sub-workflow errors are propagated to the parent (see the comment on frontend/src/flow/runFlow.ts), this test fails.
Assert that no sub-log carries an error, or target a sub-workflow that contains no llm node.

In `@frontend/src/test/subagents.test.ts` around lines 88 - 113, Strengthen the
nested workflow test around runFlow so it verifies recursive execution completed
without errors, not merely that output.subLogs contains an initial trigger.
Assert that no entry in output.subLogs carries an error, or use a sub-workflow
without an llm node when gateways is empty; keep the existing parent and
subagent assertions intact.

This change introduces full-featured support for executing, rendering, and exporting/documenting nested Subagents (sub-workflows) within the browser-side AI workflow builder. It replaces static simulated schematic placeholders with recursive in-browser execution, adds a select dropdown for target workflow configurations in the node inspector, and renders subLogs and stateSnapshots within collapsible panels in the run logs drawer. Also updates Python and JavaScript code generation to include self-documenting nested workflow details (name, node count, edge count). Includes a comprehensive test suite covering all logic and outputs.
