+**Tip — use filter flags to pre-screen at fetch time:**

+  --type new_creation --type near_completion \
+  --filter-preset safe --sort-by smart_degen_count

+Using `--filter-preset safe` (or `strict`) tells the server to pre-filter results before returning — equivalent to Steps 2's "Discard immediately" criteria, applied before the response is sent.

 ## Step 2 — First-Pass Filter (In-Response Scan)
 
+> **If you used `--filter-preset safe` or `--filter-preset strict` in Step 1, the rug_ratio, bundler_rate, and insider_ratio checks below are already applied server-side.** Verify the remaining signals manually.

 Before running any CLI commands per token, apply a quick in-response filter on the trenches results:
