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

setup-shared-folder 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 1mo 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.

Setup Shared Folder

Creates a private GitHub repo for syncing files between the machine running GhostClaw and the user's primary machine.

Use when:

  • User wants files from GhostClaw accessible on another machine
  • User wants to avoid Dropbox/Google Drive/iCloud
  • User mentions "shared folder", "sync files", "access files on my laptop"

What it does

  1. Creates ~/ghostclaw-shared/ directory structure:

    • variant/ - Variant HTML/React exports
    • projects/ - Project files
    • scratch/ - Temp workspace
  2. Initializes git repo

  3. Creates private GitHub repo (under GhostClaw's GitHub account)

  4. Pushes initial commit

  5. Gives user clone instructions

Usage

# On GhostClaw's machine (already done by skill):
cd ~/ghostclaw-shared
# Repo created and pushed

# On user's machine (tell them to run):
git clone https://github.com/ziggythebot/ghostclaw-shared.git
cd ghostclaw-shared

Workflow after setup

When GhostClaw saves files:

# GhostClaw does this automatically:
cd ~/ghostclaw-shared
cp /path/to/file variant/
git add .
git commit -m "Add variant export"
git push

User gets files:

# User runs on their machine:
cd ~/ghostclaw-shared
git pull
# Files now available locally

Auto-sync option (optional)

For automatic pulling on user's machine:

# Add to crontab on user's machine:
*/5 * * * * cd ~/ghostclaw-shared && git pull -q

Implementation

#!/bin/bash

# Create directory structure
mkdir -p ~/ghostclaw-shared/{variant,projects,scratch}
cd ~/ghostclaw-shared

# Initialize git
git init
echo "# GhostClaw Shared Files

Synced workspace between GhostClaw and your main machine.

- \`variant/\` - Variant HTML/React exports
- \`projects/\` - Project files
- \`scratch/\` - Temp workspace

## Usage

Pull latest files:
\`\`\`
git pull
\`\`\`
" > README.md

git add .
git commit -m "Initial commit"

# Create private GitHub repo
gh repo create ghostclaw-shared --private --source=. --push

echo "✓ Shared folder created at ~/ghostclaw-shared"
echo "✓ GitHub repo: https://github.com/$(gh api user -q .login)/ghostclaw-shared"
echo ""
echo "On your main machine, run:"
echo "  git clone https://github.com/$(gh api user -q .login)/ghostclaw-shared.git"

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.
