claude-workbench CLAUDE.md

claude-workbench CLAUDE.md is an instructions file for coding agents from eqms/claude-workbench. It costs 7,804 tokens per session, scanned A, original, MIT.

Project instructions for claude-workbench, a Rust terminal application that combines a file browser, preview pane, and several embedded command-line sessions. It also documents the project’s development and release setup.

In plain words
What is it for?
Use it when modifying claude-workbench, understanding its terminal interface and components, following its development workflow, or pushing changes to both configured remotes.
Why use it?
It gives coding agents the project context and rules needed to work consistently, including development commands and the requirement to keep two Git repositories in sync.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

claude-workbench CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

A Rust-based TUI (Terminal User Interface) multiplexer called "claude-workbench" that provides an integrated development environment with:

  • File browser with preview pane
  • Multiple embedded PTY terminals (Claude Code, LazyGit, User Terminal)
  • Mouse and keyboard navigation
  • Scrollback support for terminal panes

Built with Ratatui (TUI framework), Crossterm (terminal handling), and portable-pty (pseudo-terminal).

Git Push Strategy

IMPORTANT: This repository uses dual-remote push strategy. Always push to both remotes:

git push origin main      # GitLab: gitlab.ownerp.io
git push upstream main    # GitHub: github.com/eqms/claude-workbench.git

Both repositories must be kept in sync for all commits. This ensures the project is available as Open Source on GitHub with pre-built binaries via GitHub Actions.

Remotes:

Remote URL Purpose
origin [email protected]:ki/workbench.git Primary development
upstream [email protected]:eqms/claude-workbench.git Open Source distribution

Architecture

Core Components

App State (src/app.rs)

  • Main application struct holding all state
  • Manages 5 panes: FileBrowser, Preview, Claude, LazyGit, Terminal
  • Event loop with 16ms polling for responsive UI
  • Mouse and keyboard event routing based on active pane
  • PTY synchronization: syncs cd commands to Terminal and Claude panes when directory changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
