Claude Code sandbox-runtime configuration experiments (Docker support)

Claude Code Sandbox Configuration Experiments

Experimenting with sandbox-runtime configuration for Claude Code on Linux.

Goals

  • Enable sandbox per-project using /sandbox command in Claude Code CLI
  • Allow Docker commands to run unsandboxed (so containers work)
  • Allow sandboxed commands to communicate with Docker via /var/run/docker.sock

Before diving into the details, here’s a quick overview of what you need to know:

  • Primary chain: ZCHF (Frankencoin) liquidity lives almost entirely on Ethereum, with its top trading pairs on Uniswap V3/V4.
  • Multichain support: Although Frankencoin is bridged to 35 EVM-compatible networks, virtually all volume and holdings are on Ethereum.
  • Wallets: Any ERC-20-compatible wallet will work—MetaMask, Coinbase Wallet, Trust Wallet, Zerion, Zeal (built on Safe contracts), etc.
  • Swapping BTC → ZCHF: The easiest is via Mt Pelerin’s Swap feature (custodial), or non-custodially by wrapping BTC into wBTC and trading on Uniswap (Ethereum). You can also use wBTC as collateral in a 3 % p.a. Lombard loan to borrow CHF.
  • Use case: Convert BTC exposure into a CHF-pegged stablecoin on-chain—ideal for blocking in fiat value while staying in DeFi, and earning yield on ZCHF.

Claude Code doing TOO MUCH - What to do?

2025-06-28:

Here is example of claude code doing TOO MUCH, here was just asked to "rebase" , but instead it "rebased and merged"...

> subagent: for PR in 122, 123, 124, 125, 126, 127 { rebase PR on a top of PR-1  (if PR-1 already
  merged then on a top of latest changes in master) }

Here are several strategies you can combine to avoid running your full suite on every single commit and to scope down Cypress (or any other heavy) tests only when they’re really needed:

1. Use Path-Based Triggers & Job-Level Filters

A. Workflow-level paths / paths-ignore

Robust <prefix> g Pane-Zoom Hook for Outer tmux

Whether you’re juggling multiple windows and panes across nested tmux sessions, having a single, ergonomic shortcut to switch and zoom panes can save you valuable time. This snippet extends your outer tmux configuration to bind <prefix> g for a seamless, two-step pane selection: un-zoom the current pane, display a long-lasting pane number overlay, and automatically zoom the pane you choose—all in one intuitive command.

Use this snippet in your ~/.ubertmux to bind <prefix> g so it:

  • Works whether the current pane is zoomed or not
  • Displays pane numbers overlay for up to 600 seconds (10 minutes)
  • Allows you to select any pane (including the same one) and zoom it automatically
