BasicShell 0.5.0

Download: one of two, each with BasicShell.app inside: unzip, move it to Applications.

• BasicShell-0.5.0.zip: BasicShell.
• BasicShell-0.5.0-agent.zip: the same with the agent tools. The plain one has no part of them.

It is self-signed, not an Apple Developer ID, so the first time macOS refuses to open it: open it once, then System Settings › Privacy & Security › Open Anyway.

Requires: macOS 27 on Apple silicon.

In both builds

• Full screen beside the notch: the menu bar and the Dock are macOS's own auto-hiding ones now. The menu bar sometimes came halfway down and went back up; macOS does that when the options change while the pointer rests at the top, so they are set once. It comes down when the pointer touches the top, without the earlier rest, and the top bar moves below it.
• Closing the tab shown goes back to the one shown before it, not to its neighbour.

In the build with the agent tools (Settings › Agents; they are no longer called Claude's, and any MCP client can connect)

• 46 tools, handed over as a short list; help gives the whole description of one.
• Fewer round trips: a click, key or fill says what changed; open and navigate list the page; new fill_form, search and read_pages (up to 25 addresses in one call). Waits end when the page is still, not after fixed times.
• screenshot takes max_width, quality, marks, and full_page with tile or overview.
• Settings › Agents › Connect can write a skill for Claude Code, and the activity list shows how long each call took.
• Files on this Mac are one site an agent asks for; what a page asks while an agent works in it is answered no; "Remember" starts ticked.

After updating, quit and reopen BasicShell, and start a new chat in your agent if you use the build with its tools.
