+## Infrastructure
+
+### 25. Tool Auto-Provision
+
+When an agent needs a tool that isn't installed, it should install it automatically — not block and ask.
+
+- Container should support on-demand tool installation (apt, npm, go install, curl binary)
+- Dockerfile covers the 80% case; auto-install covers the long tail
+- Log what was installed so it can be baked into the Dockerfile later
+- Never let a missing `jq` or `go` derail a 30-minute sprint
+
+**Origin:** "Wenn irgendwas fehlt wie go — wir brauchen die Möglichkeit ein Tool passthru oder auto-install zu ermöglichen"
