+## Critical Merge Warning: Sinister-Quotes Placeholder
+
+When merging branches that touch prompt placeholder formatting in:
+- `packages/opencode/src/cli/cmd/tui/component/prompt/index.tsx`
+- `packages/app/src/components/prompt-input.tsx`
+
+**PRESERVE THIS FORMAT** (no "Ask anything" prefix, no extra quotes):
+```tsx
+placeholder={... : `${PLACEHOLDERS[store.placeholder]}`}
+// or for web app:
+: `${PLACEHOLDERS[store.placeholder]}`}
+```
+
+**REJECT THIS FORMAT** (old format that must NOT be kept):
+```tsx
+placeholder={... : `Ask anything... "${PLACEHOLDERS[store.placeholder]}"`}
+```
+
+This is marked with **CRITICAL MERGE WARNING** comments in the source.
+A test in `test/tui/sinister-quotes.test.ts` validates this - merges that clobber the format will fail tests.
