+# Feedback Loop
+
+## Pattern
+Set up automated feedback, give AI permission to iterate autonomously until goal is reached.
+
+1. Identify clear success signal (tests pass, UI matches design, coverage hits X%)
+2. Give AI access to that signal (tests, devtools, linter, logs)
+3. Grant explicit permission: "Keep iterating until tests pass"
+4. Step away - AI checks its own work and keeps refining
+
+Human elevates from tactical executor to strategic director.
+
+## Example
+
+**Bug fix with DevTools MCP:**
+- Goal: Fix layout bug in web app
+- Signal: DevTools screenshots showing the visual issue
+- Setup: Point AI to devtools
+- Permission: "Keep trying until the layout matches the design"
+- AI iterates: change code → check screenshot → adjust → repeat
+
+**Debugging with console logs:**
+- Goal: Understand why feature behaves incorrectly
+- Signal: Console output showing timing, state, assumptions
+- Setup: "Add console.log to help yourself understand what's wrong"
+- Permission: "Debug this until you find the root cause"
+- AI iterates: add logs → run → validate assumptions → adjust → repeat
+
+**Getting tests to pass:**
+- Goal: All tests green
+- Signal: Test runner output
+- Permission: "Fix the failing tests, keep running them until they all pass"
+- AI iterates: read failure → fix code → run tests → repeat
+
+**CI monitoring:**
+- Goal: Green CI build
+- Signal: Direct access to CI state/logs (e.g., via `gh` CLI)
+- Permission: "Monitor CI and fix issues until build passes"
+- AI iterates: check status → read logs → fix → push → check again
