### Configure Vite Dev Server to Open dev.html

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This snippet shows how to configure Vite's development server to automatically open 'dev.html' upon starting the dev server. It demonstrates two methods: modifying the vite.config.mjs file or updating the npm script. Both methods keep the production build logic intact and allow access to index.html if needed.

```javascript
import { defineConfig } from 'vite'
import { svelte } from '@sveltejs/vite-plugin-svelte'

export default defineConfig(({ command }) => ({
  plugins: [svelte()],
  build: {
    outDir: '../src/main/resources/mop-web',
    emptyOutDir: true
  },
  // Only for `vite dev` server
  server: {
    port: 5173,
    // Open /dev.html instead of /
    open: command === 'serve' ? '/dev.html' : undefined
  }
}))
```

```json
"scripts": {
  "dev": "vite --port 5173 --open /dev.html",
  ...
}
```

--------------------------------

### Handling Blocking Calls Safely

Source: https://github.com/brokkai/brokk/blob/master/app/src/main/interruptions.md

app/build/reports/tests/test/index.html
joern-analyzers/build/reports/tests/test/index.html
```

--------------------------------

### SearchAgent Interruption Handling

Source: https://github.com/brokkai/brokk/blob/master/app/src/main/interruptions.md

The `SearchAgent` checks for interruptions using `Thread.interrupted()` at the start of its loop. In interactive mode, the first interruption triggers 'Beast Mode' for a final answer, while subsequent interruptions or any interruption in non-interactive mode throws `InterruptedException`.

```java
public void execute(...) throws InterruptedException {
    while (Thread.interrupted()) { // Checks and clears interrupt status
        // ... perform search actions ...
        try {
            determineNextActions(...);
            executeToolCalls(...);
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt(); // Re-interrupt
            throw e;
        }
    }
}
```

It also lists additional configuration keys that Brokk supplements to LiteLLM's model_info.

```APIDOC
Model Naming Requirements:
  - gemini-2.0-flash: Required for system tasks.
  - gemini-2.0-flash-lite: Required for system tasks.

Brokk's Supplemental Model Info Keys:
  - free_tier_eligible: boolean (defaults to false)
  - is_private: boolean (defaults to false)
  - supports_reasoning_disable: boolean (defaults to false)
  - concurrent_requests: integer (defaults to null)
  - tokens_per_minute: integer (defaults to null)

Upgrade Agent Configuration:
  - One of {concurrent_requests, tokens_per_minute} must be set to use Upgrade Agent with the model.
```

### Brokk MOP Initialization with Proxy

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/index.html

This JavaScript code snippet initializes the Brokk MOP. It creates a global `window.brokk` object using a Proxy. This proxy intercepts all property accesses, buffering calls and events into a sequence-ordered array. It's designed to handle early calls from Java before the main application logic is ready.

```javascript
function() {
  const buffer = []; // Unified buffer for all calls and events
  let seq = 0; // Sequence number to maintain order
  window.brokk = new Proxy({
    _buffer: buffer
  }, {
    get(target, prop) {
      // Allow direct access to internal buffer
      if (prop === '_buffer') {
        return target[prop];
      }
      // Return a stub function for any other property access
      return (...args) => {
        if (prop === 'onEvent') {
          console.log('Buffering early event from Java:', JSON.stringify(args));
          buffer.push({ type: 'event', payload: args[0], seq: seq++ });
        } else if (prop === 'hideSpinner') {
          console.log('Buffering early call from Java to', prop);
          buffer.push({ type: 'call', method: prop, args: [], seq: seq++ });
        } else {
          console.log('Buffering early call from Java to', prop);
          buffer.push({ type: 'call', method: prop, args: args, seq: seq++ });
        }
        // Provide default return values for synchronous methods
        if (prop === 'getSelection') {
          return '';
        }
        return undefined;
      };
    }
  });
})();

### Brokk MOP Initialization and Proxy

Source: https://github.com/brokkai/brokk/blob/master/app/src/main/resources/mop-web/index.html

Initializes the Brokk MOP by creating a proxy that intercepts and buffers all early calls and events from Java. It maintains a sequence number to ensure ordered processing.

```javascript
function() {
  const buffer = []; // Unified buffer for all calls and events
  let seq = 0; // Sequence number to maintain order
  window.brokk = new Proxy({
    _buffer: buffer
  }, {
    get(target, prop) {
      // Allow direct access to internal buffer
      if (prop === '_buffer') {
        return target[prop];
      }
      // Return a stub function for any other property access
      return (...args) => {
        if (prop === 'onEvent') {
          console.log('Buffering early event from Java:', JSON.stringify(args));
          buffer.push({ type: 'event', payload: args[0], seq: seq++ });
        } else if (prop === 'hideSpinner') {
          console.log('Buffering early call from Java to', prop);
          buffer.push({ type: 'call', method: prop, args: [], seq: seq++ });
        } else {

        }
        // Provide default return values for synchronous methods
        if (prop === 'getSelection') {
          return '';
        }

### Update UI with Search Results and Column Fitting

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This snippet updates the UI with search results, populating the commits table and fitting column widths. It selects the first commit if available. If no commits are found, it resets the changes tree and revision information and outputs a 'not found' message.

```java
SwingUtilities.invokeLater(() -> {
    commitsTableModel.setRowCount(0);
    changesRootNode.removeAllChildren();
    changesTreeModel.reload();
    if (commitRows.isEmpty()) {
        revisionTextLabel.setText("Revision:");
        revisionIdTextArea.setText("N/A");
        chrome.systemOutput("No commits found matching: " + query);
        return;
    }
    for (Object[] rowData : commitRows) {
        commitsTableModel.addRow(rowData);
    }
    chrome.systemOutput("Found " + commitRows.size() + " commits matching: " + query);
    if (commitsTableModel.getRowCount() > 0) {
        // Fit column widths
        TableUtils.fitColumnWidth(commitsTable, 1); // Author
        TableUtils.fitColumnWidth(commitsTable, 2); // Date
        commitsTable.setRowSelectionInterval(0, 0); // Listener will handle updates to revision display and changes tree
    } else {
        // Ensure changes area and revision display are cleared if no search results
        changesRootNode.removeAllChildren();
        changesTreeModel.reload();
        revisionTextLabel.setText("Revision:");
        revisionIdTextArea.setText("N/A");
    }
});

### Brokk JavaScript API Implementation

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This snippet defines the core Brokk JavaScript object, which acts as an interface to a Java bridge. It includes methods for handling events, managing user selection, clearing content, setting themes, and displaying spinners. It also handles the replaying of buffered events and method calls that occurred before the main Brokk object was fully initialized.

```javascript
const bufferedEvents = window.brokk._eventBuffer || [];
window.brokk = {
  _callQueue: [],
  _eventBuffer: [],
  onEvent: (payload) => {
    console.log('Received event from Java bridge:', JSON.stringify(payload));
    eventStore.set(payload);
    if (payload.epoch) {
      requestAnimationFrame(() => {
        if (window.javaBridge) {
          window.javaBridge.onAck(payload.epoch);
        }
      });
    }
  },
  getSelection: () => {
    return window.getSelection()?.toString() ?? '';
  },
  clear: () => {
    eventStore.set({ type: 'chunk', text: '', isNew: true, msgType: 'SYSTEM', epoch: 0 });
  },
  setTheme: (dark) => {
    themeStore.set(dark);
    if (dark) {
      document.body.classList.add('theme-dark');
    } else {
      document.body.classList.remove('theme-dark');
    }
  },
  showSpinner: (message) => {
    spinnerStore.set(message);
  }
};

if (bufferedEvents.length > 0) {
  console.log('Replaying', bufferedEvents.length, 'buffered events');
  bufferedEvents.forEach(event => {
    window.brokk.onEvent(event);
  });
}

if (pendingCalls.length > 0) {
  console.log('Replaying', pendingCalls.length, 'buffered method calls');
  pendingCalls.forEach(({ method, args }) => {
    console.log('Replaying call to', method, 'with args:', args);
    const brokk = window.brokk as Record<string, (...args: unknown[]) => unknown>;
    if (typeof brokk[method] === 'function') {
      brokk[method](...args);
    } else {
      console.warn('Method', method, 'no longer exists; skipping replay');
    }
  });
}
```

```javascript
const buffer = window.brokk._buffer || [];
window.brokk = {
  _buffer: [],
  onEvent: (payload) => {
    console.log('Received event from Java bridge:', JSON.stringify(payload));
    eventStore.set(payload);

      requestAnimationFrame(() => {
        if (window.javaBridge) {
          window.javaBridge.onAck(payload.epoch);
        }
      });
    }
  },
  getSelection: () => {
    return window.getSelection()?.toString() ?? '';
  },
  clear: () => {
    eventStore.set({ type: 'chunk', text: '', isNew: true, msgType: 'SYSTEM', epoch: 0 });
  },
  setTheme: (dark) => {
    themeStore.set(dark);
    if (dark) {
      document.body.classList.add('theme-dark');
    } else {
      document.body.classList.remove('theme-dark');
    }
  },
  showSpinner: (message) => {
    spinnerStore.set(message);
  }
};

if (buffer.length > 0) {
  console.log('Replaying', buffer.length, 'buffered items');
  buffer.sort((a, b) => a.seq - b.seq).forEach(item => {
    if (item.type === 'event') {
      console.log('Replaying event with epoch:', item.payload.epoch);
      window.brokk.onEvent(item.payload);
    } else {
      console.log('Replaying call to', item.method, 'with args:', item.args);
      const brokk = window.brokk as Record<string, (...args: unknown[]) => unknown>;
      if (typeof brokk[item.method] === 'function') {
        brokk[item.method](...item.args);
      } else {
        console.warn('Method', item.method, 'no longer exists; skipping replay');
      }
    }
  });
}

### JavaScript Simulate Event and Show Edit MD

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This JavaScript code snippet defines functions to simulate events and display markdown content. `showEditMd` simulates 'chunk' events with user and AI content, followed by a custom message. `streamEdit` is a placeholder for editing functionality.

```javascript
function showEditMd() {
  simulateEvent('chunk', {text: contentUser, msgType: 'USER', streaming: false})
  simulateEvent('chunk', {text: ai, msgType: 'AI', streaming: false})
  simulateEvent('chunk', {text: "# Now we are finished!", msgType: 'CUSTOM', streaming: false})
}
function streamEdit() {
  const contentUser = `fix it`;
  const contentAi = `I understand the issue with the ordering of buffered events and calls in the JavaScript code, which causes the UI to sometimes clear at the end due to incorrect replay order. The problem stems from having two separate buffers (\`_callQueue\` and \`_eventBuffer\`) and replaying them in the wrong order. I'll fix this by unifying the buffer into a single queue with a sequence number to maintain the correct order of operations during replay. Here's the plan: 1. Modify the temporary stub in \`index.html\` to use a single buffer with a sequence number. 2. Update the replay logic in \`index.ts\` to process this unified buffer in sequence order. Here are the *SEARCH/REPLACE* blocks to implement these changes: <<<<<<< SEARCH frontend-mop/index.html // Immediately define brokk with a proxy to buffer all early calls from Java (function() { const callQueue = [ ] // Stores {method, args} for all calls except onEvent const eventBuffer = [ ] // Stores payloads for onEvent window.brokk = new Proxy({ _callQueue: callQueue, _eventBuffer: eventBuffer }, { get(target, prop) { // Allow direct access to internal queues if (prop === '_callQueue' || prop === '_eventBuffer') { return target[prop]; } // Return a stub function for any other property access return (...args) => { if (prop === 'onEvent') { console.log('Buffering early event from Java:', JSON.stringify(args)); eventBuffer.push(...args); } else { console.log('Buffering early call from Java to', prop); callQueue.push({ method: prop, args }); } // Provide default return values for synchronous methods if (prop === 'getSelection') { return ''; } return undefined; }; } }); })(); ======= // Immediately define brokk with a proxy to buffer all early calls from Java (function() { const buffer = [ ] // Unified buffer for all calls and events let seq = 0 // Sequence number to maintain order window.brokk = new Proxy({ _buffer: buffer }, { get(target, prop) { // Allow direct access to internal buffer if (prop === '_buffer') { return target[prop]; } // Return a stub function for any other property access return (...args) => { if (prop === 'onEvent') { console.log('Buffering early event from Java:', JSON.stringify(args)); buffer.push({ type: 'event', payload: args[0], seq: seq++ }); } else { console.log('Buffering early call from Java to', prop); buffer.push({ type: 'call', method: prop, args: args, seq: seq++ }); } // Provide default return values for synchronous methods if (prop === 'getSelection') { return ''; } return undefined; }; } }); })(); >>>>>>> REPLACE \`\`\` frontend-mop/src/index.ts <<<<<<< SEARCH // Retrieve buffered calls and events from the early stub const pendingCalls = window.brokk._callQueue || [] co

### Markdown Playground Input Handling

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This code snippet sets up an event listener for the 'input' event on an element with the ID 'md-playground'. When the input value changes, it clears the previous Brokk state and then simulates a 'chunk' event with the new content, marked as AI-generated and streaming.

```javascript
const mdInput = document.getElementById('md-playground');
let rafId = 0;
mdInput.addEventListener('input', () => {
  cancelAnimationFrame(rafId);
  rafId = requestAnimationFrame(() => {
    window.brokk.clear();
    simulateEvent('chunk', { text: mdInput.value, msgType: 'AI', streaming: true });
  });

This code populates the `commitsTableModel` with commit data. It then adjusts column widths for 'Author' and 'Date' and selects the first row if commits are present. If no commits are found, it clears the changes tree and revision information.

```java
for (Object[] rowData : commitRows) {
    commitsTableModel.addRow(rowData);
}
// Fit column widths for author and date
TableUtils.fitColumnWidth(commitsTable, 1); // Author column
TableUtils.fitColumnWidth(commitsTable, 2); // Date column
if (commitsTableModel.getRowCount() > 0) {
    commitsTable.setRowSelectionInterval(0, 0); // Listener will handle updates to revision display and changes tree
} else {
    // Ensure changes area and revision display are cleared if no commits
    changesRootNode.removeAllChildren();
    changesTreeModel.reload();
    revisionTextLabel.setText("Revision:");
    revisionIdTextArea.setText("N/A");
}
```

### Brokk Initialization and Event Buffering

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

Initializes the Brokk object with a proxy to buffer early calls and events from Java. This ensures that no interactions are lost before the main application logic is ready. It includes a sequence number to maintain the order of operations.

```javascript
function () {
  const buffer = [];
  let seq = 0;
  window.brokk = new Proxy({
    _buffer: buffer
  }, {
    get(target, prop) {
      if (prop === '_buffer') {
        return target[prop];
      }
      return (...args) => {
        if (prop === 'onEvent') {
          console.log('Buffering early event from Java:', JSON.stringify(args));
          buffer.push({type: 'event', payload: args[0], seq: seq++});
        } else if (prop === 'hideSpinner') {
          console.log('Buffering early call from Java to', prop);
          buffer.push({type: 'call', method: prop, args: [], seq: seq++});
        } else {
          console.log('Buffering early call from Java to', prop);
          buffer.push({type: 'call', method: prop, args: args, seq: seq++});
        }
        return undefined;
      };
    }
  });
})();
```

### Modify GitLogTab for Commit Browser Panel

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This Java code snippet demonstrates how to modify the GitLogTab class to correctly integrate the GitCommitBrowserPanel. It addresses an issue where 'commitBrowserPanel' was referenced but not properly initialized, and adjusts the panel's weight and addition to the log panel.

```java
// ============ Commit Browser Panel (center ~80%) ============ 
// Original code might have had an issue with commitBrowserPanel initialization
// This section shows the corrected way to initialize and add it.

// Example of initialization (assuming GitCommitBrowserPanel exists)
// commitBrowserPanel = new GitCommitBrowserPanel(chrome, contextManager);

// Corrected panel initialization and addition to the layout
JPanel commitBrowserPanel = buildCommitBrowserPanel(); // Assuming this method builds the panel

// ... other panel setup ...

constraints.gridx = 1; // commit browser (commits + changes)
constraints.weightx = 0.80;
logPanel.add(commitBrowserPanel, constraints);

// ... logging and button state updates ...
// logger.warn("Could not select any local branch (target: {}, current git: {}). Clearing commits.", previouslySelectedBranch, currentGitBranch);
// commitBrowserPanel.setCommits(List.of());
// pullButton.setEnabled(false);
// pushButton.setEnabled(false);
```

### Brokkai/Brokk License Terms

Source: https://github.com/brokkai/brokk/blob/master/LICENSE.txt

Details the conditions for distributing and modifying the Brokkai/Brokk project. It covers copyright notices, warranty disclaimers, and requirements for providing the source code when distributing in object code form.

```text
Project: /brokkai/brokk
Content:
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:

    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.

    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".

    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

  A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:

    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.

    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.

    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.

    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.

### Simulate Brokk Events and Chunk Processing

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This snippet demonstrates how to simulate Brokk events, specifically 'clear' and 'chunk' events, which are used for managing chat-like interfaces. It shows how to send user input and AI-generated content in chunks, simulating a streaming effect for the AI's response.

```javascript
let index = 0;
simulateEvent('clear');
simulateEvent('chunk', {text: contentUser, msgType: 'USER', streaming: true});
const chunks = contentAi.match(/[\s\S]{1,10}/g) || [];
const interval = setInterval(() => {
  if (index < chunks.length) {
    simulateEvent('chunk', {text: chunks[index], msgType: 'AI', streaming: true});
    index++;
  } else {
    clearInterval(interval);
  }
}, 10);
```

### JavaScript Event and Call Buffering (Unified Buffer)

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

This JavaScript code snippet shows an improved method for buffering early calls and events using a single unified buffer with sequence numbers. It replaces separate queues for calls and events, ensuring correct replay order by processing items based on their sequence.

```javascript
(function() {
  const buffer = []; // Unified buffer for all calls and events
  let seq = 0; // Sequence number to maintain order
  window.brokk = new Proxy({
    _buffer: buffer
  }, {
    get(target, prop) {
      // Allow direct access to internal buffer
      if (prop === '_buffer') {
        return target[prop];
      }
      // Return a stub function for any other property access
      return (...args) => {
        if (prop === 'onEvent') {
          console.log('Buffering early event from Java:', JSON.stringify(args));
          buffer.push({ type: 'event', payload: args[0], seq: seq++ });
        } else {
          console.log('Buffering early call from Java to', prop);
          buffer.push({ type: 'call', method: prop, args: args, seq: seq++ });
        }
        // Provide default return values for synchronous methods
        if (prop === 'getSelection') {
          return '';
        }
        return undefined;
      };
    }
  });
})();
```

### Java Git Create Pull Request API

Source: https://github.com/brokkai/brokk/blob/master/frontend-mop/dev.html

Provides a Java method `createPullRequest` for creating GitHub pull requests. It handles generating titles and bodies if they are blank, checks for uncommitted changes, and ensures the operation is not performed on the default branch. It also includes error handling and logging.

```APIDOC
createPullRequest(title: String, body: String)
  @Tool("Create a GitHub pull-request for the current branch. " +
          "If title or body is blank they are auto-generated. " +
          "This implicitly pushes the branch and sets upstream when needed.")
  public String createPullRequest(
      @Nullable @P("PR title (optional)") String title,
      @Nullable @P("PR description in Markdown (optional)") String body)
    // Parameters:
    //   title: PR title (optional). If blank, it will be auto-generated.
    //   body: PR description in Markdown (optional). If blank, it will be auto-generated.
    // Returns: A string containing the URL of the created pull request.
    // Throws:
    //   IllegalStateException: If the current directory is not a Git repository, cannot determine the default branch, has uncommitted changes, or is attempting to create a PR from the default branch.
    //   RuntimeException: If any other exception occurs during the process.
    {
      var cursor = messageCursor();
      io.llmOutput("Creating pull request…", ChatMessageType.CUSTOM, true);

            .orElseThrow(() -> new IllegalStateException("Cannot determine default branch"));
        var currentBranch = repo.getCurrentBranch();
        if (Objects.equals(currentBranch, defaultBranch)) throw new IllegalStateException("Refusing to open PR from default branch (" + defaultBranch + ')');
        if (!repo.getModifiedFiles().isEmpty()) throw new IllegalStateException("Uncommitted changes present; commit first");
        var gws = new GitWorkflowService(contextManager);
        // Auto-generate title/body if blank
        if (title == null || title.isBlank() || body == null || body.isBlank()) {
          var suggestion = gws.suggestPullRequestDetails(currentBranch, defaultBranch);
          if (title == null || title.isBlank()) title = suggestion.title();
          if (body == null || body.isBlank()) body = suggestion.description();
        }
        var prUrl = gws.createPullRequest(currentBranch, defaultBranch, title.trim(), body.trim());
        var msg = "Opened PR: " + prUrl;
        io.llmOutput(msg, ChatMessageType.CUSTOM);
        logger.info(msg);
        // Persist result to history
        var newMessages = messagesSince(cursor);
        contextManager.addToHistory(new TaskResult(contextManager, "Git create PR", newMessages, Set.of(), TaskResult.StopReason.SUCCESS), false);
        return msg;
      } catch (Exception e) {
        var err = "Create PR failed: " + e.getMessage();
        io.llmOutput(err, ChatMessageType.CUSTOM);
        logger.error(err, e);
        var newMessages = messagesSince(cursor);
