+	## Agent Container (packnplay)
+
+	Agents run inside [packnplay](https://github.com/obra/packnplay) containers with `--dangerously-skip-permissions`. packnplay mounts `~/.claude`, handles credentials, creates worktrees, and preserves host paths.
+
+	- [ ] packnplay installed (`brew install obra/tap/packnplay`)
+	- [ ] packnplay configured (`packnplay configure` — enable git, ssh, gh, aws credentials)
+	- [ ] Dev wiki MCP accessible from container — configure MCP endpoint as `http://host.docker.internal:8190/mcp` (not `localhost`) since container `localhost` is the container itself
+	- [ ] Verify: `packnplay run --aws-creds claude` launches and can reach the wiki MCP
+	- [ ] Agent launch command documented: `packnplay run --aws-creds --worktree=<phase> claude --dangerously-skip-permissions`
