+
+## Changes
+
+### Improved system prompt for edit_file workflow (`ollama-client.ts`)
+- Expanded `TOOL_SYSTEM_PROMPT` with a mandatory numbered workflow: get path, read file, copy exact text, then edit.
+- Added explicit rules: never skip reading, never guess file contents, never leave old_text empty on non-empty files.
+- Documented the empty-file exception: old_text may be empty only when the file itself is empty.
+
+### Improved edit_file tool description and parameters (`tools.ts`)
+- Updated the `edit_file` function description to instruct the model to call `read_file` first.
+- Documented the empty-file special case in both the function description and the `old_text` parameter description.
+- Updated `executeEditFile` to allow empty `old_text` when the file is truly empty (writes initial content).
+- When `old_text` is empty but the file has content, returns a descriptive error guiding the model to read the file first.
+- Improved error messages on match failure to remind the model to read the file first.
+
+### Added edit details to approval prompt (`chat-view.ts`)
+- The `edit_file` approval prompt now includes a collapsible "Review changes" section (expanded by default).
+- Shows labeled "Old text" and "New text" blocks so the user can review the full change before approving.
+- Empty old_text displays "(empty — new file)" placeholder.
+
+### Added edit details to tool call summary (`chat-view.ts`)
+- The `edit_file` tool call details section now shows structured "File", "Old text", and "New text" labels instead of raw JSON args.
+
+### Added CSS for tool call labels (`styles.css`)
+- Added `.ai-organizer-tool-call-label` styling for the labeled sections in edit_file details.
