Safe workflow
Use the smallest reversible workflow first. Do not add community plugins or paste credentials while validating the base behavior.
- Check runtime and OS prerequisites.
- Run only the official command shown in the versioned code block.
- Verify the version and local URL before configuring a provider.
Verify before moving on
A successful result should be observable: a version string, reachable local URL, valid provider response, loaded configuration, or disappearance of the exact error. If the result differs, stop and capture sanitized evidence rather than stacking unrelated fixes.
- Record the exact dsh, Node or Python version.
- State the operating system and installation method.
- Link the first-party source and include only sanitized logs.
First-party sources
Open the original source before acting on a changed version or unresolved community report.
