Show HN: Shannon – Local desktop app to orchestrate Claude Code agent teams

I ran into a problem when using Claude Code CLI on larger projects: I wanted to split work across specialized agents (one writes code, another reviews, another runs tests) and coordinate them with dependency graphs. Managing this across multiple terminal sessions was painful.

Shannon solves this:

- Create customized agents with different models (Opus/Sonnet/Haiku) and system prompts - Build team workflows with a drag-and-drop DAG editor (parallel, sequential, or fully custom) - Describe your goal in natural language → AI analyzes your codebase and proposes a task plan with dependencies - Watch everything in real-time: task graph, agent chat, code diffs

There's also a Monaco-based prompt editor with semantic syntax highlighting for XML tags (the kind Claude responds well to), autocomplete, and an "AI Improve" button that rewrites your system prompt in one click.

Tech: Go backend, React frontend, Wails v2 for the desktop shell, SQLite for storage. It shells out to the Claude Code CLI under the hood — not calling the API directly — so you get all of Claude Code's built-in tools (file editing, bash, etc.)

Named after Claude Shannon, as you might guess.

Limitations: requires Claude Code CLI installed and authenticated. Local-only desktop app. Hobby project — expect rough edges. Workspace copies can eat disk space on large repos.
