 ## How to delegate
 
 Pass file *paths*, not file *contents*. If you read the input files yourself before invoking, you have already paid the token cost the skill exists to avoid.

+## Failure handling
+
+MiniMax intermittently returns `invalid system role` and other transient errors. Retry once. If it fails again, fall back to a Claude subagent with the same brief — Sonnet for file-heavy grunt work, Opus for reasoning-grade consults. Never silently drop the task. Log new error shapes to the project's `memory/gotchas-*.md`.
