Get Workflow Execution Result
Overview
This skill retrieves the result (return value) of a completed workflow execution. Use it after a workflow started with npx output workflow start has completed, or to retrieve results from historical runs.
When to Use This Skill
- Getting output from an asynchronously started workflow
- Retrieving results from a completed workflow
- Checking what a workflow produced
- Processing workflow output in scripts
- Comparing results between runs
Prerequisites
- The workflow must have completed (status: COMPLETED)
- You need the workflow ID
- For FAILED workflows, use
npx output workflow debuginstead
Instructions
Get Result
npx output workflow result <workflowId>
The result is the return value of the workflow function, typically JSON.
Check Status First
Before getting results, verify the workflow completed:
npx output workflow status <workflowId>
# Should show: COMPLETED
npx output workflow result <workflowId>
Understanding Results
Success Results
A successful workflow returns the value from its fn function:
// Workflow code
export default workflow({
fn: async (input) => {
return { processed: true, count: 42 };
}
});
# Result output
npx output workflow result abc123
# { "processed": true, "count": 42 }
Error Results
If you try to get the result of a failed workflow:
- You'll get an error message
- Use
npx output workflow debuginstead to see what went wrong
No Result (void workflows)
Some workflows don't return a value:
npx output workflow result abc123
# null
Examples
Scenario: Get result after async start
# Start workflow
npx output workflow start calculate '{"values": [1, 2, 3]}'
# Output: Workflow ID: calc-abc123
# Wait for completion
npx output workflow status calc-abc123
# Status: COMPLETED
# Get the result
npx output workflow result calc-abc123
# { "sum": 6, "average": 2 }
Scenario: Process result with jq
# Extract specific field
npx output workflow result abc123 | jq '.total'
# Format for display
npx output workflow result abc123 | jq '.'
# Save to file
npx output workflow result abc123 > result.json
Scenario: Compare results between runs
# Get results from two runs
npx output workflow result run-1-abc > result1.json
npx output workflow result run-2-xyz > result2.json
# Compare
diff result1.json result2.json
Scenario: Use in a script
WORKFLOW_ID="abc123"
# Wait for completion
while [[ $(npx output workflow status $WORKFLOW_ID) == *"RUNNING"* ]]; do
sleep 5
done
# Check if completed successfully
if [[ $(npx output workflow status $WORKFLOW_ID) == *"COMPLETED"* ]]; then
RESULT=$(npx output workflow result $WORKFLOW_ID)
echo "Workflow result: $RESULT"
else
echo "Workflow did not complete successfully"
npx output workflow debug $WORKFLOW_ID
fi
Handling Different Result Types
JSON Objects
npx output workflow result abc123
# { "key": "value", "nested": { "data": true } }
Arrays
npx output workflow result abc123
# [1, 2, 3, 4, 5]
Primitive Values
npx output workflow result abc123
# 42
npx output workflow result abc123
# "success"
npx output workflow result abc123
# true
Large Results
For large results, redirect to a file:
npx output workflow result abc123 > large-result.json
Error Handling
"Workflow not found"
- Check the workflow ID is correct
- Use
npx output workflow runs listto find valid IDs
"Workflow not completed"
- Check status:
npx output workflow status <id> - Wait for COMPLETED status before getting result
- If RUNNING, wait and try again
- If FAILED, use
npx output workflow debug
"No result available"
- The workflow may return void/undefined
- Check the workflow code to see what it returns
