+## Discovering Commands

+**Agents: always prefer `--schema` over `--help`** — `--schema` returns JSON; `--help` returns human prose.
+
+```bash
+# Machine-readable surface (use this)
+agentmail auth --schema
+agentmail auth <method> --schema
+
+# Human-readable help (for humans)
+agentmail auth --help
+```
