WRAI.TH: Skill for Claude Code

.claude/skills/review-installation/SKILL.md

review-installation is a skill for Claude Code from TsukumoHQ/WRAI.TH. It costs 132 tokens per session (1,565 once invoked), scanned D, original, AGPL-3.0.

A review checklist for installer changes, covering shell and PowerShell install scripts, operating-system services, and clean-machine smoke tests.

In plain words
What is it for?
Use it when changing install.sh, install.ps1, install-smoke files, Makefile installer commands, or launchd and systemd service setup.
Why use it?
Installers run with a user's permissions on machines the author does not control, so mistakes can affect setup and system services.

Skill for Claude Code

Written for Claude Code: paths in frontmatter.

This is TsukumoHQ/WRAI.TH's own configuration. It tells Claude Code how to work on WRAI.TH 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 WRAI.TH 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 D, and why

review-installation scanned grade D with 3 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 11d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
