Where a function is defined and who calls it, from the compiler. What is broken right now. Then a setup script that asks questions, answered in a terminal inside the chat.
What happens in this clip
  1. Ask where a function is defined and who calls it. The answer comes from the project's own language server, not a text search.
  2. Ask what is broken right now and the current errors come back per file.
  3. Errors are re-checked after every edit the assistant makes.
  4. A setup script runs in a terminal inside the chat and asks its questions there.
  5. The assistant reads the prompt on screen and answers it.

A staged file open as a side-by-side diff beside the Source Control panel, removed lines in red and added lines in green with their line numbers, before anything is committed.

Integrated Source Control

Review AI-generated changes with a full diff viewer before committing. See staged and unstaged changes, review line-by-line additions and deletions, and commit directly from the app.

  • Side-by-side diff view with syntax highlighting
  • Staged and unstaged change tracking
  • One-click commit with auto-generated messages
  • Branch information at a glance
The Source Control panel: a Site card offering Build and preview or Start dev server, a commit message box with an AI drafting button, one staged change and one unstaged change, each showing its path and its added and removed line counts.

AI-Generated Commit Messages

The built-in source control panel analyzes your staged diff and recent git history to write conventional commit messages (feat, fix, refactor, docs). Stage changes, review diffs, and commit without leaving the app.

  • AI analyzes staged diff and recent history
  • Press Commit with the box empty and it writes the message for you
  • Conventional commit format (feat, fix, refactor, docs)
  • Stage and unstage files directly
  • Branch info and change count at a glance
The Create Hook dialog: name and description, the event set to Pre-Tool Use with the note that it is the only event that can stop a tool, a hook type chosen from Command, HTTP, Agent or Workflow, and matcher patterns that narrow it to specific tools.

Automation Hooks

Create pre- and post-tool-use hooks to automate workflows. Run linters before commits, send webhooks when files change, or enforce coding standards automatically.

  • Pre-Tool Use and Post-Tool Use event triggers
  • Command or HTTP webhook actions
  • Regex-based tool matchers for targeted automation
  • Global or per-project scope
The Prompt panel: a tool-selection card explaining forced selection for structured output, and a few-shot examples card with label, input and output fields and an Add Example button.

Prompt Engineering Panel

Fine-tune how the AI responds with the built-in prompt engineering panel. Set tool choice preferences, add few-shot examples, and control the AI's behavior at a granular level.

  • Tool choice configuration (any, required, specific)
  • Few-shot example management
  • Direct control over AI behavior

More Developer Capabilities

Browser Automation

Navigate, click, type, screenshot, and extract content from any website. Uses your real Chrome profile so the AI can work with authenticated sites.

Advanced File Operations

Parallel file processing with 30 concurrent workers, git-blob checkpoints for every edit (5-10ms each), and atomic multi-file restore.

Git-Blob Checkpoints

Every file edit is backed up as a git blob. Restore any checkpoint instantly, or rewind the entire session to a previous state.

Context Intelligence

Deep project analysis with 15+ language detection, dependency awareness, smart file selection, and auto-condensing when approaching context limits.

Connects to

Nothing here works alone. See the whole map for how the pieces fit together.

What feeds it

  • Code Intelligence feeds this.

    Errors it introduces while editing come back with the edit, so they are fixed in the same reply.

Where it goes

  • This feeds Publish Sites.

    The Source Control panel is where a site is set up and published.

  • This feeds Shell Commands.

    Source control, hooks and prompt engineering sit in the same workflow as the terminal.
