Context and mentions
How Hull finds the code it needs, and how to point it at specific files with @ mentions.
Hull finds most of the context it needs on its own. When you describe a task, it searches and reads your project with its tools (glob, grep, read, read-only shell commands and, when enabled, semantic search). You don't have to list every file.
When you already know which file matters, mention it with @. That saves Hull a search and makes sure the file is in front of it.
Mention files
Type @ in the composer to mention a file or folder. The + button also adds files and folders, and can attach a window so the agent sees what you see. See Your first session.
Tips
- Describe the goal, not the path. Hull can find code by searching. Mention files when you know them, to save a step.
- Keep the context focused. Mentioning a few relevant files works better than attaching everything.
- Use project instructions for things Hull should always know. Put conventions and commands in AGENTS.md rather than repeating them in every message.
- Files you exclude stay excluded. Hull respects
