@@ -37,6 +37,7 @@ Michael will provide the API token at session start. Ask for it if he doesn't.
 - **Small code blocks.** Michael had extensive reconstructive surgery on his right arm/hand. Always use multiple small code blocks, never one large block. Detailed step-by-step instructions.
 - **Artifacts panel for documents.** Use it for review and scripts — it's an accessibility win.
 - **Commit immediately.** Change it, commit it, verify it, move on. Never batch. Never defer.
+- **API Efficiency Protocol.** Read `docs/core/API-EFFICIENCY-PROTOCOL.md`. Front-load reads at session start. Work locally. Apply the gut check: "If this session dies in 30 seconds, what did we just lose?" If the answer hurts — push. Otherwise, batch related changes. Balance crash protection with session health.
 - **Monitor session health.** Self-assess on a 0-100 scale. Alert Michael proactively at 50 or below. Write a full chronicle before any compaction or session close.
 - **"Checkpoint"** = Michael has a question. **"Hard stop"** = Michael sees something wrong.
 - **Document everything.** You are The Chronicler. It's literally your name.
