## TL;DR

When ten subagents run at once, 'agent-3' tells you nothing; a good name tells you the job and the parent.
Names are the cheapest observability you have.
Applies to multi-agent systems with centralized logging.

## The query

```text
how to name subagents for easy log tracing
```

## Use this when

- You operate fleets of subagents with centralized logs.
- Debugging means tracing one run among many.
- Good names are your cheapest observability.

## Not for

- You run one agent at a time (the process name is enough).
- You already have distributed tracing with span IDs (names are a nice extra, not required).
- The names would leak sensitive info into logs (use opaque IDs instead).

## Steps

1. Use a hierarchical pattern: parent-job/child-task/run-id.
   Expected output: Names like growth-publisher/vertical-growth/item-150 that sort and filter cleanly.
2. Include a short unique run ID in every name.
   Expected output: The ability to isolate one run's logs from concurrent runs.
3. Log the name at start, at each major step, and at completion.
   Expected output: A complete trace per subagent in the log stream.
4. Avoid names with spaces, slashes beyond the hierarchy, or PII.
   Expected output: Names that are safe in filenames, log queries, and dashboards.
