What Claude Secretmode does

Leave-no-trace ephemeral Claude Code sessions on macOS — runs Claude Code on a RAM disk so transcripts, prompt history, and file snapshots never touch disk and evaporate on exit, while inheriting your keychain auth, MCP, CLAUDE.md, hooks, skills, and plugins. Drop-in for `claude` as `claude-secretmode` / `csm`.

README

claude-secretmode

**English** | [한국어](README.ko.md)

**Leave-no-trace**, disposable Claude Code sessions — runs Claude Code on a macOS RAM disk, so transcripts, prompt history, and file snapshots are **never written to disk in the first place** and evaporate wholesale on exit.

Type `claude-secretmode` (or `csm`) where you would normally type `claude` — that's it. Auth, MCP, CLAUDE.md, and plugins all work as usual, while that session's **transcript and prompt history** never touch the disk. Your original `~/.claude` conversation history is preserved and never polluted.

Quick start (1 minute)

1. Prerequisites

macOS (Apple Silicon / Intel)
Claude Code installed and logged in
- npm install -g @anthropic-ai/claude-code, then log in once via claude
- Auth is inherited from the macOS Keychain (Claude Code-credentials)

2. Install

# npm
npm install -g @younggichoi/claude-secretmode

# or bun
bun add -g @younggichoi/claude-secretmode

3. Use

# instead of your usual claude — this session leaves no records on disk
claude-secretmode

# short alias
csm

# arguments are passed through to claude as-is
claude-secretmode --model opus

On exit (Ctrl-D, `/exit`, or closing the terminal) the RAM disk is detached and every trace of the session disappears.

How it works

claude-secretmode starts
 └ create a RAM disk → point CLAUDE_CONFIG_DIR at it
    ├ Keychain token → /.credentials.json (auth inherited)
    ├ .claude.json (past-project traces stripped), settings.json (recording hooks disabled)
    ├ CLAUDE.md · hooks · skills · plugins → symlinks (code & policy shared as-is)
    └ transcript / history / snapshots → written to RAM only
 └ run claude (interactive, as usual)
    └ (background) token-sync daemon — keeps whichever token is newer,
      Keychain or RAM session (prevents rollback)
[exit] → RAM disk detached → session traces evaporate. The original ~/
