- Added
`/review`

, which sends a specialized message to the agent based on your current Git context - Added configurable chain-of-prompts, allowing to go from
`brainstorm`

to`plan`

to`code`

and ending with`/review`

- Added opt-in pre-configured MCPs for Context7 and Grep.app
- Added
`--load-prompt`

and`--pure-stdout`

, allowing for better scripts and tools built on top of zerostack - Added support for signaling agent's activity via UNIX sockets, allowing for better scripts and tools built on top of zerostack
- Added installations via scripts, Nix and Homebrew
- Added special permissions to allow
`plan`

prompt to write`PLAN*.md`

files

**Improvements:**

- Added ability to select directories using
`@`

- Improved color rendering
