Problem Statement

When working with Claude Code, I've noticed that Markdown files (CLAUDE.md, HANDOFF.md, plan/, rules/) are a more important control layer for me than the actual source code. They define context, conventions, current project state, and session handoffs.

What I'm missing in the Mac app: a sidebar to browse and read these Markdown files, without having to trigger Read-calls in the chat or keep an external editor open in parallel.

Idea: not the full project tree (usually too noisy), but a curatable doc tree with configurable paths — for example:

Project CLAUDE.md hierarchy (auto-detected)
plan/ or docs/ folders
Global rules (~/.claude/rules/)
Memory files
This would let me see at a glance what context Claude has actually loaded, and maintain it without interrupting the chat flow.

Read-only with syntax highlighting would already be enough — editing can still happen via chat.

Proposed Solution

Sidebar to easy navigate the md files context an read word edit it within th Claude Code App
