PatchCairn helps a capable local AI assistant investigate your computer, explain its findings, and coordinate supported changes you approve. **Use its `PatchCairn:` requests in the assistant's chat.** The local CLI supports documented helper operations; it does not turn a chat request into a PowerShell, Bash, or Terminal command. The assistant keeps the technical records and brings the decisions to you in ordinary language.
The [documentation website](https://sacitdev.github.io/PatchCairn/) explains setup, the four jobs, and everyday use. Your computer's reports, private records, and operating controls stay local.
All four jobs belong to one PatchCairn project and use the same start. The public product version is recorded in [toolkit.json](toolkit.json); technical record-format identifiers describe internal components.
