# `toolchain.artifact_write_failed`

Generated file could not be written.

Area 14, [Tooling](../topics/tooling.md); not declinable; the next step is usually the human's.

No example yet. Only a command raises this error, so no source shows it;
the CLI's own tests do (`crates/jadpo-cli/tests`), and
[Command errors](../topics/command-errors.md) lists the
command that raises it.
