What the assistant can do
The assistant · 3 min read
The assistant can change files, run project checks, inspect responsive layouts and accessibility, keep a dev server running, and show its plan as a checklist.
When you would want it
When it cannot do a job with a proper tool, an assistant improvises with shell commands no Undo can reverse, gives up on anything slower than half a minute, or tells you to run the server yourself. With the right tools it just does the job, and you can put it back.
Where to find it
- All Features → What the assistant can do
- Show the built-in tools
What you get out of it
- Nothing the assistant deletes or moves is gone for good: one Undo puts the whole turn back.
- "npm install" and full test runs finish instead of timing out after thirty seconds.
- A dev server keeps running for the rest of the conversation instead of blocking it.
- Search shows the lines around each match and finds code like add( as plain text, so the assistant reads less to find more.
- Edits survive an indentation mismatch instead of failing and starting over, and documentation pages come back as clean text, not raw HTML.
How to use it, step by step
- Ask for the job in plain words - "move the images into assets and fix the links", "rename utils.js to helpers.js", "delete the old landing page", "start the dev server and check the home page".
- Deletes, moves and renames happen with proper file tools, not shell commands. The Changed files card under the answer lists them, deletions struck through, and Undo puts every one back - images and other binary files byte for byte.
- Long commands - installs, builds, test suites - may run for up to ten minutes and report their real exit code. Press Stop and the command ends along with everything it started.
- Servers and watchers run in the background while the assistant keeps working: it reads what they print, spots the address a dev server announces, and looks at it. They stop when you close the folder or quit.
- For a bigger job, a Plan card appears in the conversation with every step, ticked off as each one finishes.
- To see every tool in plain words, run Tools: The Assistant's Built-in Tools from the command palette.
Why this beats the usual way
Agents without these tools improvise: rm and mv in a shell, which no Undo reverses; servers started in the foreground that hang the turn; thirty-second limits that kill every install. Agentfly gives the assistant the tools a careful engineer would use, puts every file change under one Undo, and shows its plan while it works, so you can let it run and still put things back.
