In plain words
What is it for?
Use it to prepare a computer for web, Python, AI, or data projects. It provides separate installation guidance for macOS and Windows.
Why use it?
It removes the guesswork from preparing a computer for a software project. It also checks whether the required tools are already installed before giving setup instructions.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is ccivlcid/VibeHarness's own configuration. It tells Claude Code how to work on VibeHarness itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything VibeHarness configures →

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 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 2mo 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.
