+### Environment and networked CLI note
+
+If your workflow depends on environment variables from the launching shell, launch Codex with
+shell environment inheritance enabled:
+
+```yaml
+codex:
+  command: codex --config shell_environment_policy.inherit=all app-server
+```
+
+If the agent must use networked tools during a turn, configure an explicit
+`codex.turn_sandbox_policy` that allows network access, for example:
+
+```yaml
+codex:
+  approval_policy: never
+  thread_sandbox: workspace-write
+  turn_sandbox_policy:
+    type: workspaceWrite
+    writableRoots:
+      - /tmp/symphony_workspaces
+    readOnlyAccess:
+      type: fullAccess
+    networkAccess: true
+    excludeTmpdirEnvVar: false
+    excludeSlashTmp: false
+```
+
+With that in place, env-based credentials exported before launching Symphony are available to turn
+commands. If a specific external CLI still does not find usable credentials in your environment,
+provide that tool's credential explicitly via an env var such as `GH_TOKEN`, `GITHUB_TOKEN`, or a
+provider-specific API key.
+
+The exact accepted sandbox and approval values depend on the installed Codex app-server version. To
+inspect the local schema, run `codex app-server generate-json-schema --out <dir>` and inspect the
+generated `ThreadStartParams` and `TurnStartParams` schema files.
