Edit an Existing Project

​

Overview

This tutorial covers how to safely modify existing Projects, whether you created them, inherited them from teammates, or are exploring community templates. Time required: 15-20 minutes

​

Step 1: Open the Project

1. Navigate to Home in the Top Bar
2. Find your Project in the Projects list
3. Click to open it on the Canvas

You’ll see the Project’s component graph.

​

Step 2: Understand the structure

Before making changes, map out what exists:

1. Review the Canvas — Note all Flows, Agents, and Actions
2. Check dependencies — See which components depend on others
3. Read documentation — Look for README or descriptions
4. Ask Triton — Type: “Explain what this Project does”

Triton will analyze the structure and provide a summary.

​

Step 3: Identify what to change

Common modification scenarios:

​

Adding a new feature

Example: Add email notifications to a data processing pipeline

1. Create a new Action: send_email
2. Add it to the relevant Flow
3. Connect it after the processing step
4. Configure SMTP settings in Project Variables

​

Modifying an existing component

Example: Update an Agent’s prompt

1. Select the Agent node
2. Open Properties → Content
3. Edit the System Prompt
4. Save changes (auto-saved)
5. Test with a sample payload

​

Replacing a component

Example: Swap out an Action for a better implementation

1. Create the new Action
2. Ensure it has the same input/output schema
3. Disconnect the old Action
4. Connect the new one
5. Delete the old Action
6. Test thoroughly

​

Debugging an issue

Example: A Flow is failing intermittently

1. Go to Properties → Executions
2. Find failed execution
3. Examine logs and errors
4. Identify the failing component
5. Ask Triton: “Why is this Action failing?”
6. Apply the fix
7. Re-run execution

​

Step 4: Make the changes

Let’s walk through a specific example: Adding retry logic to an API call

​

Current state

Your fetch_data Action sometimes fails due to network timeouts.

​

Goal

Add automatic retry with exponential backoff.

​

Steps

1. Open the Action
   • Double-click the fetch_data node
   • Review the current Action.py
2. Ask Triton for help
   • “Add retry logic with exponential backoff to this Action”
   • Triton will update the code with a retry decorator
3. Review the changes
   Copy

   Ask AI

   from tenacity import retry, stop_after_attempt, wait_exponential
   
   @retry(
       stop=stop_after_attempt(3),
       wait=wait_exponential(multiplier=1, min=2, max=10)
   )
   def fetch_data(url: str) -> dict:
       # existing implementation
   

4. Update requirements.txt
   • Add tenacity==8.2.3
5. Test the change
   • Execute with a payload that previously failed
   • Verify retries happen (check logs)
   • Confirm eventual success

​

Step 5: Test your changes

Always test modifications before deploying:

​

Unit test individual components

1. Select the modified component
2. Use Properties → Execute with test data
3. Verify expected behavior

​

Integration test the full Flow

1. Select the top-level Flow
2. Execute with realistic payloads
3. Check all outputs are correct

​

Edge case testing

Test with:

• Empty inputs
• Maximum size inputs
• Invalid data
• Network failures (if applicable)

​

Step 6: Document your changes

Help your future self and teammates:

1. Update descriptions
   • Select the component
   • Update the description field
   • Note what changed and why
2. Update README
   • If the Project has a README, add notes
   • Document new dependencies or requirements
3. Add comments in code
   • Explain non-obvious logic
   • Note any workarounds or constraints

​

Step 7: Deploy the updates

Once tested:

1. Click Deploy in the Top Bar
2. Select the environment
3. Review changes (diff view if available)
4. Add deployment notes
5. Click Deploy Now

For production Projects:

• Deploy to staging first
• Run smoke tests
• Monitor for issues
• Then deploy to production

​

Step 8: Monitor post-deployment

After deploying:

1. Watch initial executions
   • Check the first few runs succeed
   • Look for unexpected errors
2. Compare metrics
   • Success rate before vs. after
   • Execution time
   • Error types
3. Set up alerts
   • Get notified if new issues arise
   • Track key metrics

​

Common modification patterns

​

Adding authentication

1. Create Project Variable for API key
2. Update relevant Actions to use the key
3. Test with valid and invalid keys

​

Scaling for more data

1. Identify bottlenecks (single-threaded Actions)
2. Add parallel processing in Flows
3. Implement batching if needed
4. Test with large payloads

​

Improving error handling

1. Add try-catch blocks in Actions
2. Return structured error responses
3. Add error routing in Flows
4. Set up failure notifications

​

Optimizing performance

1. Profile slow components
2. Add caching where appropriate
3. Reduce unnecessary data passing
4. Parallelize independent operations

​

Best practices

Version control — Save the current state before major changes (export/backup)

Small iterations — Make one change at a time, test, then move on

Ask for help — Use Triton to explain complex parts before modifying

Test thoroughly — Don’t skip testing, especially for production Projects

Communicate — If working in a team, coordinate changes

​

Troubleshooting

Problem: Changes aren’t taking effect
Solution: Ensure you saved, redeploy if already deployed, clear any caches Problem: Breaking existing functionality
Solution: Review execution logs, compare with previous version, test each component Problem: Can’t understand the existing code
Solution: Ask Triton to explain it, check for documentation, trace execution flow Problem: Changes work locally but fail in production
Solution: Check environment differences, verify Project Variables are set, review logs
