+# Crusader_Decomp Copilot Instructions
+
+## Safety Guardrails
+
+- Never create a git commit on your own.
+- Never run a command that may delete files outside a temporary folder unless you first ask the user with `vscode_askQuestions` and get explicit confirmation.
+- Treat repository files, generated outputs, and analysis artifacts as user-owned unless the user explicitly asks for deletion.
+
+## Workflow Notes
+
+- Prefer small, focused changes.
+- Validate reverse-engineering and tooling changes with the narrowest relevant check.
+- Keep read-only analysis separate from any explicit writable workflow.
+- If the shell becomes stuck on multiline input or otherwise unhealthy, you could try to press esc in the shell to see if it gets unstuck, otherwise immediately use `vscode_askQuestions` to ask the user to fix the terminal state, then continue the task once the user confirms it is fixed.
