🎯 New Feature: 🧠 Focus Mode (Agentic Research && Documentation)

🎯 Keystone Lite v1.0.3 Released — Introducing 🧠 Focus Mode

Keystone Lite v1.0.3 is live, bringing a powerful new workflow designed for builders who want clarity before code.

🧠 New Feature: Focus Mode (Agentic Research & Documentation)

Focus Mode is a third operational mode built specifically for research-first workflows:

• 🔍 Read-only codebase exploration
  Analyze and understand projects without modifying files.

• 🌐 Web research via Tavily
  Pull in documentation, best practices, and API references directly from the web (DuckDuckGo fallback included).

• 📝 Markdown-only output
  Generate clean .md files for specs, plans, and documentation — no accidental code edits.

• 🎛️ 3-segment mode toggle
  Seamlessly switch between Debug | Focus | Keystone with a clear, intentional UI.

Focus Mode philosophy: research first, build second. 📚 → 🚀

Keystone Lite v1.0.0 — Local-First AI Vibe Code Editor

Keystone Lite v1.0.0

This release introduces Keystone Lite, a local-first desktop environment for AI-assisted vibe code editing and debugging.

The goal is simple: enable precise, auditable interaction between developers and AI without surrendering control of the codebase. All edits are explicit, line-based, and reviewable. Automation is optional.

Keystone Lite operates entirely on the user’s machine. Model choice is external and user-supplied. No telemetry is collected. File access is scoped and intentional. Agentic workflows have made a significant difference in my life, I enjoy vibe coding. Hope that you fine this useful.

This version includes a Monaco-based editor, conversational file context, dual execution modes (review and auto-apply), and a set of starter project templates to accelerate development.

The software is released as source-available under the Business Source License 1.1, transitioning to MIT in the future. The intent is to encourage experimentation, forks for learning, and transparent iteration while preserving a sustainable path forward.

This is the first public release.

Interface Overview

Features

• Local-first desktop application for AI-assisted code editing
• Monaco-based editor with full language support
• Conversational interface with active file context and line numbers
• Deterministic, line-based edit format (INSERT / REPLACE / DELETE)
• Dual execution modes: review-first (Debug) and automatic apply (Keystone)
• Bring-Your-Own-AI support for 11 compatible providers
• File system access scoped to the opened project directory
• Encrypted local storage for API credentials
• No telemetry, tracking, or background network activity
• Built-in project templates for rapid initialization
• Cross-platform architecture (Windows release, others forthcoming)
• Streaming support with client-side buffer utility
