claude-code-portable CLAUDE.md

claude-code-portable CLAUDE.md is an instructions file for coding agents from SonnyTaylor/claude-code-portable. It costs 700 tokens per session, scanned A, original, MIT.

Repository instructions for a portable Claude Code launcher that runs from a USB drive or any folder without installation. They describe its scripts, structure, and constraints.

In plain words
What is it for?
Use them when changing or reviewing the launcher scripts, configuration, portable downloads, or platform-specific behavior.
Why use it?
They give the coding agent the project context needed to work safely, including supported systems, download checks, and where local state is stored.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-code-portable CLAUDE.md scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

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

What This Is

A portable launcher for Claude Code that runs from a USB drive or any folder with no installation. Three launcher scripts (claude.ps1 as the primary Windows launcher, claude.cmd as the Windows fallback, and claude.sh for macOS/Linux) download the official Claude Code binary, optionally download Portable Git (Windows only), and configure environment variables so all state stays within this folder.

Architecture

The project has no build system, tests, or dependencies -- it is purely shell scripts.

  • claude.ps1 - Primary Windows launcher (PowerShell, uses Invoke-WebRequest for downloads, Get-FileHash for SHA256 verification)
  • claude.cmd - Windows batch fallback launcher (used when PowerShell is unavailable; auto-forwards to claude.ps1 when possible)
  • claude.sh - macOS/Linux bash launcher (uses curl for downloads, sha256sum/shasum for verification)
  • config.example - Template for optional API key / proxy configuration
  • data/CLAUDE.md - Auto-generated starter CLAUDE.md placed into the portable config directory by the launcher scripts on first run

All three launchers share identical logic:

  1. Create bin/, data/, tmp/ directories
  2. Create a default data/CLAUDE.md if missing
  3. Handle subcommands (update, version, setup, --help)
  4. Load config file (key=value pairs) into environment if it exists
  5. Download Claude Code binary from GCS bucket with SHA256 verification if not present
  6. On Windows: find or download Portable Git
  7. Set CLAUDE_CONFIG_DIR=data/, CLAUDE_CODE_TMPDIR=tmp/, DISABLE_AUTOUPDATER=1
  8. Exec the binary, forwarding all arguments

Binary downloads come from https://storage.googleapis.com/claude-code-dist-86c565f3-f756-42ad-8dfa-d59b1c096819/claude-code-releases. The version manifest at {bucket}/{version}/manifest.json contains per-platform SHA256 checksums.

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.
