Good addition: The awaitingUserInput: true flag correctly signals that the workflow is waiting for the user to handle authentication before proceeding. This prevents the multi-step loop from auto-confirming while credentials are pending. ✅

Correct placement: Adding the flag here is right - when clarification questions are returned after a modification, the loop should pause and wait for the user's answers. ✅

Consistent pattern: The modified workflow preview correctly includes the flag. This ensures the user sees the updated draft and must confirm before deployment. ✅

Edge case handling: When a "new" workflow generation fails and the previous draft is restored, the awaitingUserInput flag is correctly set. This keeps the user in the loop with the restored draft rather than failing silently. Good defensive programming! ✅

Clarification flow: Correctly returns awaitingUserInput: true when the LLM identifies that clarification questions need to be answered. The multi-step loop will pause here until the user provides answers. ✅

Preview generation: The initial workflow preview correctly includes the flag. This is the core use case - after generating a draft, the system waits for user confirmation before deploying. ✅
Type Safety ConsiderationWhile reviewing, I noticed that the Current approach: Suggestion: Consider creating a local type to make the return structure more explicit: interface WorkflowActionResult extends ActionResult {
data?: {
awaitingUserInput?: boolean;
// ... other fields like WorkflowCreationResult
}
}This would:
Note: This is not blocking - the current implementation is functionally correct. Just a nice-to-have for enhanced type safety. |

Good test practice: Using optional chaining (`result?.data`) prevents tests from failing with null reference errors if the action handler has issues. The assertion verifies both the structure and the specific flag value. ✅
Consider: You might also want to add a test that explicitly verifies the flag is NOT present (or is false) in terminal states like deployment success or cancellation, to ensure the behavior is complete.
Test Coverage ObservationThe tests comprehensively cover the happy paths where
Missing test coverage (optional enhancement):
This would ensure the multi-step loop correctly terminates in these scenarios and doesn't wait indefinitely for user input. Example: test('deployment success does not set awaitingUserInput flag', async () => {
// ... setup to trigger deployment
const result = await createWorkflowAction.handler(...);
expect(result?.success).toBe(true);
expect(result?.data?.awaitingUserInput).toBeUndefined();
}); |
Architectural Pattern ReviewThe ✅ Consistency with Other ActionsI reviewed
🎯 Correct Usage PatternThe flag is correctly used ONLY for:
The flag is correctly EXCLUDED from:
📊 Return Value PatternsLooking at the return statements:
This distribution looks correct for a multi-step workflow creation process. |
Version BumpThe
Consideration for FutureIf this becomes a public API contract that other plugins depend on, you might consider:
For now, the version bump is correct as-is. |
Security Review: ✅ No Issues FoundI've reviewed the changes with a security lens: API Key & Credentials

Data Exposure

Validation
Conclusion: This PR is security-neutral - it neither improves nor degrades the security posture of the plugin. |

Potential Edge Cases to ConsiderWhile reviewing, I identified a few edge cases that may be worth considering (none are blockers): 1. Race Conditions in Multi-User ScenariosScenario: Multiple API calls for the same user while a draft is pending Current behavior: The cache key is Edge case: If the same user makes concurrent requests, the last write wins. This is probably acceptable for this use case, but worth documenting if it becomes an issue. 2. Cache Expiration Edge CaseCode location: Lines 277-281 in if (existingDraft && Date.now() - existingDraft.createdAt > DRAFT_TTL_MS) {
logger.debug({ src: "plugin:n8n-workflow:action:create" }, "Draft expired, clearing cache");
await runtime.deleteCache(cacheKey);
existingDraft = undefined;
}Question: What happens if a user's draft expires while they're composing a response? Current behavior: The draft is cleared, and the user's next message is treated as a new workflow request. This seems reasonable, but you might want to:
3. Callback Failure ScenariosPattern in code: if (callback) {
await callback({ text, success: true });
}
return { success: true, data: { awaitingUserInput: true } };Edge case: What if Overall: These are low-probability edge cases. The current implementation handles the main flows correctly. Document or track these if they become issues in production. |
