Reinstalling a Claude Code Environment
This technical how-to explains how to rebuild a local Claude Code development environment on a new machine. The article describes that Claude Code's global environment is stored in a single directory (~/.claude/) containing CLAUDE.md, settings.json, hooks, commands, memories and per-project memory folders. These files do not sync automatically between machines. The author documents a reproducible approach: keep a bootstrap prompt (a document containing the exact CLAUDE.md, reference files, settings.json, statusline script, plugin list and global memories) which instructs Claude to recreate the files and configuration on the new host. The post also details a statusline script that scrapes the /usage endpoint and caches usage in usage-exact.json, lists required utilities (bash 4+, jq, tmux, python3), and explains plugin reinstall commands and which memories are worth migrating first.
Practical technical guidance for developers using Claude Code and local LLM tooling; useful for LLM developer workflows but not industry-shifting.

Key Takeaways & Evidence Grounding
- Claude Code stores its global environment in ~/.claude/, which contains CLAUDE.md, settings.json, hooks/, commands/, memory/, and projects/<cwd>/memory/.
- Files in ~/.claude/ are not versioned or synced by default and are lost when changing machines unless migrated.
- A bootstrap prompt containing the exact CLAUDE.md, reference files, settings.json, statusline script, plugin list, and global memories can recreate the environment when provided to Claude on a new machine.
- A statusline script (requiring bash 4+, jq, tmux, python3) scrapes the /usage endpoint and caches results in ~/.claude/usage-exact.json to show token consumption and estimates.
- Claude Code plugins install via 'claude plugins install <plugin-name>' and can be reinstalled with a single command if the plugin list is preserved.

CLAUDE.md: Guide to Configuring Claude Code
This DEV.to tutorial (published 2026-06-21) explains CLAUDE.md, a small markdown file that Claude Code reads at the start of every session to provide project-specific context. The article describes what to include (stack with versions, directory map, build/test commands, conventions, generated files), where to put it (project root), and how to bootstrap it using Claude Code's /init command. The author argues a concise, accurate CLAUDE.md compounds value across sessions and links to a free quick-start cheat sheet plus a paid, deeper Gumroad guide covering hooks, subagents, commands, skills and plugins.
Keeping Claude Code Context Across Desktop, Laptop, VPS
Fillip Kosorukov describes a simple git-backed workflow to preserve Claude Code (LLM-assisted coding) context across a desktop, a laptop and a VPS. His approach makes a VPS-hosted ~/knowledge directory the source of truth, with desktop and laptop acting as clones. A session-end hook auto-commits and pushes changes, a 2-hour cron job catches missed updates, and a startup ritual pulls the latest state and has the assistant read an append-only CHANGELOG.md to cold-start context. The article documents the directory layout (INDEX.md, CHANGELOG.md, scratch.md, meta/sources-of-truth.md, per-project files), two maintenance rules (one home per fact; two outputs per task), and a Karpathy-style scratch.md review process. The author reports six weeks of uninterrupted context continuity and notes operational caveats (never store secrets, verify runtime paths, enforce hooks).
What to Put in Your CLAUDE.md
This tutorial explains how to write an effective CLAUDE.md for Claude Code agents. It recommends including only lines that materially change Claude's behaviour—start with a one- or two-line project description and explicit stack versions, a top-level directory map, build and test commands, non-enforceable conventions, and explicit 'do not touch' notes. It warns against including personality instructions and rules already enforced by tools. The author introduces a pragmatic "one-line test": remove a line and keep it only if its absence would cause Claude to make a mistake. The post argues brevity improves runtime reliability because CLAUDE.md is loaded into Claude's context each session. The article links to a free CLAUDE.md cheat sheet and a paid, deeper guide on configuration stacks and agent tooling.
