+            ## Task: Analyze UI Test Failures
+
+            Please analyze the UI test failures in the current directory.
+
+            Key information:
+            - Test reports are located in: build/reports and tests/ui-ij-tests/build/reports
+            - There is a CI screen recording at build/reports/ci-screen-recording/screen-recording.mp4 that shows what happened during the entire test run - this video is usually very useful for understanding what went wrong visually
+            - There is also a single screenshot at tests/ui-ij-tests/build/reports/ideaVimTest.png showing the state when the test failed
+            - IDE sandbox logs are in the idea-sandbox-log directory
+            - ffmpeg is already installed and available. Useful commands for video analysis:
+              * Extract frame at specific time: `ffmpeg -i video.mp4 -ss 00:01:30 -vframes 1 output.png`
+              * Extract multiple frames: `ffmpeg -i video.mp4 -vf fps=1/10 frame_%04d.png` (1 frame every 10 seconds)
+              * Get video duration: `ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 video.mp4`
+              * Extract last N seconds: `ffmpeg -sseof -10 -i video.mp4 -update 1 last_frame.png` (last 10 seconds)
+              * Create thumbnail grid: `ffmpeg -i video.mp4 -vf "select='not(mod(n\,300))',scale=160:120,tile=5x5" -frames:v 1 grid.png`
+
+            Special troubleshooting for timeout failures:
+            - If the test fails because it waited for something to appear, but according to the video and screenshot the element actually appeared on screen, check the UI hierarchy file at build/reports/hierarchy-ideaVimTest.html
+            - This hierarchy file shows the actual structure of UI elements and their properties at the time of failure
+            - The failure may be caused by a renamed property or changed class name in the UI element
+            - If you find this is the case, suggest a new query or selector that matches the current element structure
+
+            Please provide:
+            1. A detailed analysis of what went wrong
+            2. The root cause of the failure
+            3. Potential fixes or suggestions
+
+            Write your analysis to build/reports/ai-analysis.txt
+
+            ## UI Test Best Practices
+
+            When fixing UI tests, follow these principles:
+
+            **Cause-Effect Over Timeouts**: UI tests should wait for specific conditions rather than arbitrary timeouts.
+            - ✅ GOOD: Wait for a button to become visible or enabled before clicking it
+            - ✅ GOOD: Wait for specific text to appear in a component
+            - ✅ GOOD: Wait for a dialog to be present with a specific accessible name
+            - ❌ BAD: Use Thread.sleep() or fixed delays
+            - ❌ BAD: Wait for arbitrary timeouts without checking for specific conditions
+
+            Only use timeouts as a maximum wait duration with explicit condition checks (e.g., "wait up to 30 seconds for dialog to appear").
+            Tests should be deterministic and based on observable state changes in the UI, not time-based assumptions.
+
+            IMPORTANT: If you have a concrete suggestion for fixing the test, ALWAYS proceed with creating a branch and PR. Never ask for permission - just do it.
+
+            If you have a concrete suggestion for fixing the test:
+            1. Create a new branch with a descriptive name (e.g., fix/ui-test-accessible-name)
+            2. Apply your suggested fix to the codebase
+            3. CRITICAL: When staging changes, NEVER use `git add -A` or `git add .`. Always add modified files explicitly by path (e.g., `git add path/to/file.kt path/to/other.kt`). This prevents accidentally staging unrelated files.
+            4. MANDATORY: Verify compilation succeeds with your changes: `gradle compileKotlin compileTestKotlin`
+            5. MANDATORY: Run the specific failing test to verify the fix improves or resolves the issue
+               - For Non-Octopus UI tests: `gradle :tests:ui-ij-tests:testUi --tests "YourTestClassName.yourTestMethod"`
+               - To run all Non-Octopus UI tests: `gradle :tests:ui-ij-tests:testUi`
+               - The test MUST either pass completely or show clear improvement (e.g., progressing further before failure)
+            6. If the test passes or shows improvement with your fix, create a PR with:
+               - Clear title describing the fix
+               - Description explaining the root cause and solution
+               - Test results showing the fix works
+               - Reference to the failing CI run
+            7. Use the base branch 'master' for the PR

-<summary><h2>VimEverywhere: Keyboard-driven IDE navigation outside the editor</h2></summary>
-
-### Summary:
-Brings vim-style keyboard navigation to the rest of the IDE. Enabling `VimEverywhere` turns on three
-behaviors:
-
-- **Hints overlay.** Press `Ctrl+Shift+\` (`Ctrl+Cmd+\` on macOS) to display hint labels over
-  interactive UI components — buttons, tool window tabs, tree nodes, text fields, scroll panes, and
-  so on. Type the letters next to a target to focus or click it without touching the mouse.
-- **NERDTree-style mappings everywhere.** NERDTree file-opening mappings (`o`, `t`, `T`, `s`, `i`,
-  `go`, `gs`, `gi`) work in any focused tree, not just the Project tool window.
-- **Tool window navigation.** Vim-style window-motion keys work inside tool windows, so you can move
-  between split panes without leaving the keyboard.
-
-### Setup:
-- Install the [AceJump](https://plugins.jetbrains.com/plugin/7086-acejump/) plugin.
-- Add the following command to `~/.ideavimrc`: `set VimEverywhere`
-
-### Instructions
-
-Press `Ctrl+Shift+\` (`Ctrl+Cmd+\` on macOS) to toggle the hints overlay. Type the letters shown
-next to a target to activate it, or press `Esc` to dismiss the overlay without activating anything.
-NERDTree-style and window-nav mappings are active automatically whenever the corresponding
-component has focus.

-Autocommands
-============
-
-IdeaVim supports Vim's `:autocmd` for running commands on editor events.
-Handlers are registered from `~/.ideavimrc` or interactively in Command-line mode.
-Every effort is made to match Vim's behaviour, but some differences are inevitable
-because the IDE's event model doesn't map 1:1 onto Vim's.
-
-Syntax
-------
-
-```
-autocmd [group] {event}[,{event}...] {pattern} {command}
-autocmd!
-autocmd! {group}
-```
-
-- `{event}` — one or more comma-separated event names (see below).
-- `{pattern}` — file pattern (see "Patterns" below). For `FileType`, the pattern matches the filetype name, not the file
-  path.
-- `{command}` — any Ex command or Vimscript expression.
-- `autocmd!` — clears all registered handlers, or all handlers in the given augroup.
-
-```vim
-augroup my_group
-  autocmd!
-  autocmd BufWritePre *.py echo "saving python"
-augroup END
-```
-
-Patterns
---------
-
-Autocmd file patterns support the following glob syntax:
-
-| Pattern     | Matches                                  |
-|-------------|------------------------------------------|
-| `*`         | Any characters except path separators    |
-| `**`        | Any characters including path separators |
-| `?`         | Any single non-separator character       |
-| `[abc]`     | Any character in the set                 |
-| `{foo,bar}` | Either `foo` or `bar`                    |
-
-If the pattern contains `/` or `\`, it matches against the full path;
-otherwise it matches against the filename only.
-
-`FileType` is special: its pattern matches against the filetype name
-(e.g. `python`, `java`) rather than the file path.
-
-Supported events
-----------------
-
-### Insert mode
-
-| Event         | Fires when           |
-|---------------|----------------------|
-| `InsertEnter` | Entering Insert mode |
-| `InsertLeave` | Leaving Insert mode  |
-
-### Buffers
-
-| Event          | Fires when                                                        |
-|----------------|-------------------------------------------------------------------|

-
-### Event order
-
-When opening a file for the first time:
-
-```
-BufRead/BufReadPost → FileType → BufEnter
-```
-
-When opening a just-created file:
-
-```
-BufNewFile → FileType → BufEnter
-```
-
-When switching buffers:
-
-```
-BufLeave → WinLeave → WinEnter → BufEnter
-```
-
-When saving:
-
-```
-BufWrite/BufWritePre → (write) → BufWritePost
-```
-
-Differences from Vim
---------------------
-
-**`FileType` names.** IdeaVim maps IntelliJ's file type name to a Vim-style
-filetype. For most languages the lowercased IJ name matches Vim's filetype
-(`Python`→`python`, `JAVA`→`java`). A small override table handles cases where
-Vim's convention differs: `PLAIN_TEXT`→`text`, `C++`→`cpp`, `C#`→`cs`,
-`Shell Script`→`sh`, `ObjectiveC`→`objc`, `JavaScript`→`javascript`,
-`TypeScript`→`typescript`, `Vue.js`→`vue`, `CMakeLists.txt`→`cmake`,
-`Handlebars/Mustache`→`handlebars`.
-
-**`BufNewFile` detection.** IdeaVim tracks files created during the session
-via the VFS. When such a file is opened in an editor, `BufNewFile` fires
-instead of `BufRead`. Files created by VCS pulls, build tools, or external
-processes that you later open in an editor will also be treated as new files.
-
-**`BufWritePre` / `BufWritePost` frequency.** IntelliJ auto-saves on focus
-loss, tab switch, build, and other events. These autocmds fire more often
-than Vim's `:w`, so handlers should be idempotent.

-/**
- * Tests for VIM-519: cycling between recent edits with `g;` and `g,`.
- *
- * Reference: Neovim 0.11 — `nv_pcmark` / `get_changelist` (`src/nvim/normal.c`,
- * `src/nvim/mark.c`) and `changed_common` (`src/nvim/change.c`).
- *
- * Semantics in one breath:
- *  - Each undoable change appends an entry; the per-window index sits AT the
- *    position past the newest entry (so the first `g;` lands on the newest one).
- *  - `g;` walks backwards (`count` older), `g,` walks forwards (`count` newer).
- *  - Same-line edits within `'textwidth'` columns of the prior entry merge into
- *    a single entry at the latest position (default 79 when `'textwidth'` is 0).
- *  - Errors:
- *      E662 "At start of changelist"  — `g;` at the oldest entry
- *      E663 "At end of changelist"    — `g,` at the newest entry
- *      E664 "Changelist is empty"     — either command with no changes recorded
- *  - `g,` from the fresh "past end" position silently clamps to the newest
- *    entry; the error fires on the *next* `g,`.
