+# Context Offloading with `/ask-minimax`
+
+`/ask-minimax` delegates a task to a MiniMax M2.7 sub-session that reads and writes files directly. Only a short summary flows back — file contents never load into this session. Reach for it when the **file payload dwarfs the answer payload**.
+
+## Use it for
+
+- Summarising large files (logs, dumps, generated reports >500 lines)
+- Extracting specific facts from multiple files or long reference docs
+- Generating big files (migrations, config bundles, fixtures, large docs) where the content does not need to flow back
+- Format conversion of large files (CSV↔JSON, XML↔YAML, etc.)
+- Bulk find-and-extract across many files where only the matches matter
+
+## Skip it for
+
+- Iterative design or debugging — the main session needs the content in context
+- Small files (under a few hundred lines) — overhead exceeds savings
+- Tasks where you will immediately re-read the result to act on it
+- Anything requiring tools MiniMax cannot use (web fetch, MCP, browser, agent dispatch)
+- Architecture or quality-sensitive output — MiniMax is for grunt work, not nuanced reasoning
+
+## 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.
