+# E2E smoke test — Minimax M2.7 via the Pi community provider
+# Verifies: Pi can resolve and call Minimax M2.7 using the user's local
+#   `pi /login` credentials (api_key entry in ~/.pi/agent/auth.json).
+# Design: mirrors e2e-pi-smoke.yaml structure. Three nodes verify
+#   (1) the model responds at all, (2) it can self-identify as Minimax,
+#   (3) it can produce parseable JSON via output_format (best-effort on Pi).
+#   The final bash node fails fast if any signal is missing.
+# Auth: requires a `minimax` entry in ~/.pi/agent/auth.json. No env vars.
+name: e2e-minimax-smoke
+description: |
+  Use when: Verifying that Minimax M2.7 loads via the Pi provider with the
+            user's local Pi auth (api_key in ~/.pi/agent/auth.json).
+  Triggers: "minimax smoke", "test minimax", "verify minimax", "minimax test".
+  Does: Sends three tiny prompts to Minimax M2.7 (math, self-identification,
+        structured JSON), asserts non-empty output and basic plausibility.
+  NOT for: Production work — connectivity / capability sanity check only.
