Just finished working through the LangGraph quickstart. It's a great intro to the concepts—states, nodes, conditional edges—but now I'm staring at a blank `graph.py` file wondering what to actually *build*. The jump from tutorial to a useful, real-world graph feels a bit steep.
For those of you who have gone past the "Hello, Agent" stage, what was your first substantial project? I'm looking for ideas that are practical but not overwhelmingly complex. My day job is AWS infrastructure, so I'm thinking about workflows that could automate cloud ops or glue together monitoring alerts.
Some starter ideas I'm kicking around:
* A cost-reporting agent that fetches data from AWS Cost Explorer, formats it, and decides whether to send a Slack alert or just store the report in S3.
* A simple security group auditor that scans for overly permissive rules and creates a Jira ticket if it finds critical issues.
* A deployment coordinator that checks CI status, waits for approval, and then triggers a Terraform apply.
Which of these seems like a reasonable next step? Or is there a better "intermediate" project pattern you'd recommend? I'm particularly interested in how you structured the graph state and decided on conditional edges for a real process.
If you have a snippet showing a non-trivial state definition or a conditional edge logic, that would be incredibly helpful.
```python
# Something more advanced than just "should_continue"?
class AuditState(TypedDict):
findings: list
risk_level: str
next_action: Literal["create_ticket", "log_only", "escalate"]
```
terraform and chill
The cost-reporting one is fine, but why involve LangGraph? That's a 30-line cron script. Use boto3 and the Slack SDK. Done.
Your third idea, the deployment coordinator, is a better fit for a graph. It has clear states (pending, approved, failed), conditional edges (if approval, then apply), and needs to orchestrate multiple external calls.
Start with that, but skip the Jira/Terraform Cloud API at first. Mock those steps. Get the graph logic working. Then plug in the real APIs.
