v1.0.0 — first public release

First tagged release of Echo — a macOS prototype that pairs the macOS Accessibility API with OpenAI GPT-4o to act as an in-context AI assistant for the frontmost app.

Highlights

• Real-time frontmost-application detection via NSWorkspace notifications.
• Accessibility-API text editing — Echo reads and updates AXTextArea content in any focused macOS app.
• Chat UI built with SwiftUI, embedded in AppKit through NSHostingController.
• OpenAI GPT-4o integration powered by MacPaw/OpenAI Swift SDK.
• Xcode 15 / macOS 14+ support.

Repository hardening (post-prototype cleanup)

• Graceful handling of a missing OPEN_AI env var (no more cryptic nil-unwrap crashes); errors now surface as user-visible chat messages.
• Removed debug print() calls from production paths.
• Build CI workflow added (compiles on every PR/push to develop).
• CodeQL workflow no longer pinned to a specific Xcode version.
• SwiftLint configuration.
• CONTRIBUTING.md, CODE_OF_CONDUCT.md, CHANGELOG.md, issue/PR templates, CODEOWNERS.
• README rewrite: real clone URL, full Xcode-scheme env-var walkthrough, troubleshooting section.

Requirements

• macOS 14.0+
• Xcode 15.0+
• An OpenAI API key (set as OPEN_AI env var)

See the README for setup instructions and the CHANGELOG for full details.

Warning

Echo is an experimental prototype that demonstrates an approach. Use at your own risk.
