Keep the daemon-based extension as the complete coding-agent path. + +## Reverse-engineering findings + +The inspected Claude 1.0.66 package contains two callers of one browser-tool +engine: + +1. a standalone side-panel runtime that creates its model client in the + extension and runs the tool loop there; and +2. optional Native Messaging bridges used by Claude Code and Claude Desktop. + +Anthropic's support documentation likewise presents ordinary Claude in Chrome +as an install-and-sign-in side panel, while the Claude Code documentation +describes a separate native integration for local coding context. + +`noemica-io/open-claude-in-chrome` reconstructs the native chain (Claude Code, +MCP, TCP bridge, native host, extension), not the standalone model runtime. + +This confirms that Qwen's pure-web version is technically feasible, but also +that local coding features are not made browser-native merely by sharing the +same UI. + +The supplied `claude_1.0.66.zip` was used only as behavioral evidence. No code +was copied from it. Its SHA-256 is +`2d085a455621f07abb649feded74c85e31b0e6ff937823e679a81475dbf95cac`, and it +contains an injected remote-configuration layer.

The user can allow or reject each action. A decision is +discarded if the active page changes before execution. + +Page content is treated as untrusted. The model prompt forbids treating page +text as higher-priority instructions and forbids requesting or entering +passwords, payment data, tokens, and other secrets. + +## Settings import + +A pure Chrome extension cannot silently read `~/.qwen/settings.json`.
