# CASAN Governed Chat for VS Code
|
||||
|
||||
This extension contributes an explicit `@casan` GitHub Copilot Chat route.
|
||||
CASAN opens admission before the selected Copilot model is called and finalizes
|
||||
the same trace after streaming completes.
|
||||
|
||||
It intentionally does **not** claim to intercept built-in Copilot chat. Use
|
||||
`@casan <prompt>` when a CASAN-owned route is required. Claude Code and Codex
|
||||
inside VS Code continue to use their own project lifecycle hooks installed by
|
||||
`casan init`.
|
||||
|
||||
The extension has no runtime dependency beyond the VS Code API and Python 3
|
||||
required by CASAN.
