The update introduces a redesigned TUI, multi-modal input support, advisors for cost-efficient model routing, and configurable chain-of-prompts, along with various improvements and bug fixes.", "body_md": "With v1.5, Zerostack has achieved feature parity with Claude Code on the most important agent capabilities, while shipping a new and improved TUI.\n\n**Additions:**\n\n- Fully re-designed TUI (w/ new input bar, new status bar & new welcome message; scroll down for screenshot)\n- Added Multi-modal inputs with support for images, audio and PDF (compile gated)\n- Added Advisors, allowing to use cheaper models that can call \"expert\" LLMs when the task is too difficult\n- Added\n`/review`\n\n, which sends a specialized message to the agent based on your current Git context - Added configurable chain-of-prompts, allowing to go from\n`brainstorm`\n\nto`plan`\n\nto`code`\n\nand ending with`/review`\n\n- Added opt-in pre-configured MCPs for Context7 and Grep.app\n- Added\n`--load-prompt`\n\nand`--pure-stdout`\n\n, 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\n- Added installations via scripts, Nix and Homebrew\n- Added special permissions to allow\n`plan`\n\nprompt to write`PLAN*.md`\n\nfiles\n\n**Improvements:**\n\n- Added ability to select directories using\n`@`\n\n- Improved color rendering\n- Better tool use TUI rendering\n- Improved compaction\n- Improved doom loop detection\n- Improved caching on list of models\n- Added more configuration options\n- Enabled caching on Antrophic models (thanks\n[@xavierforge](https://github.com/xavierforge)) - Several optimizations for local LLMs, with more coming during the v1.5.x cycle (thanks\n[hal-eisen](https://github.com/hal-eisen)) - Fixed several bugs in git worktree module", "url": "https://wpnews.pro/news/zerostack-v1-5-lightweight-unix-inspired-coding-agent", "canonical_source": "https://github.com/gi-dellav/zerostack/releases/tag/v1.5.0", "published_at": "2026-06-14 17:13:05+00:00", "updated_at": "2026-06-14 17:42:14.645510+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools", "large-language-models", "generative-ai"], "entities": ["Zerostack", "Claude Code", "Context7", "Grep.app", "Nix", "Homebrew", "Antrophic"], "alternates": {"html": "https://wpnews.pro/news/zerostack-v1-5-lightweight-unix-inspired-coding-agent", "markdown": "https://wpnews.pro/news/zerostack-v1-5-lightweight-unix-inspired-coding-agent.md", "text": "https://wpnews.pro/news/zerostack-v1-5-lightweight-unix-inspired-coding-agent.txt", "jsonld": "https://wpnews.pro/news/zerostack-v1-5-lightweight-unix-inspired-coding-agent.jsonld"}}
