Ask Astro
The best way to find out how to improve your workflow is to ask Astro. Very often, improving a step in a workflow is as simple as:- ensuring the workflow is broken up into logical steps
- improving your instructions
- asking Astro to convert a node into code to make it faster, cheaper and more reliable.
Astro will then write your changes to a draft which you can publish when you’re happy. See Build in the platform.
Find the step that costs you
Watch the recording of a slow execution and find the steps where the workflow spends the most time. The activity log gives you the same answer with numbers. Atransitioned_node entry may carry fromNodeDuration, the seconds the previous node took. See Debug your workflows.
Split a node that does too much
A node that logs in, searches, opens a record, and fills a form has four ways to go wrong. It has one place to describe them all. It also burns turns. A node that runs out of turns ends the execution ascancelled with the reason max_steps.
Split it. One node, one job, one observable end state. Each node then gets its own transitions, so a failure lands on the right path instead of ending the execution.
Ask Astro to do the split. It rewrites the instructions for each new node and rewires the transitions.
See Nodes and Transitions.
Turn a proven path into a script
A node that takes the same actions every execution does not need a model to pick them. Give it a Playwright script and those actions replay in milliseconds, for no model cost.Scripts
When to script a node, how to attach one, what it returns, and what happens when it fails
Feed real failures back into the instructions
Every failure you debug is a sentence the instructions were missing. The workflow hit a cookie banner. Add the edge case. The workflow picked the wrong search result. Add the success criteria. The workflow submitted the form twice. Say what “done” looks like. Structure each node’s instructions the same way:- Goal — what the node accomplishes.
- Ordered steps — the actions, in sequence.
- Edge cases — the variations you have seen in real executions.
- Success criteria — the condition the workflow can observe when it is finished.
Change one thing at a time. Two changes in one version make a moved number impossible to attribute.
