+# RTK - Rust Token Killer
+
+**Usage**: Token-optimized CLI proxy (60-90% savings on dev operations)
+
+## Meta Commands (always use rtk directly)
+
+```bash
+rtk gain              # Show token savings analytics
+rtk gain --history    # Show command usage history with savings
+rtk discover          # Analyze Claude Code history for missed opportunities
+rtk proxy <cmd>       # Execute raw command without filtering (for debugging)
+```
+
+## Installation Verification
+
+```bash
+rtk --version         # Should show: rtk X.Y.Z
+rtk gain              # Should work (not "command not found")
+which rtk             # Verify correct binary
+```
+
+⚠️ **Name collision**: If `rtk gain` fails, you may have reachingforthejack/rtk (Rust Type Kit) installed instead.
+
+## Hook-Based Usage
+
+All other commands are automatically rewritten by the Claude Code hook.
+Example: `git status` → `rtk git status` (transparent, 0 tokens overhead)
+
+Refer to CLAUDE.md for full command reference.

+# This is a thin delegating hook: all rewrite logic lives in `rtk rewrite`,
+# which is the single source of truth (src/discover/registry.rs).
+# To add or change rewrite rules, edit the Rust registry — not this file.

+# Exit code protocol for `rtk rewrite`:
+#   0 + stdout  Rewrite found, no deny/ask rule matched → auto-allow
+#   1           No RTK equivalent → pass through unchanged
+#   2           Deny rule matched → pass through (Claude Code native deny handles it)
+#   3 + stdout  Ask rule matched → rewrite but let Claude Code prompt the user
