go2cs: Skill for Claude Code

.claude/skills/gate-forensics/SKILL.md

gate-forensics is a skill for Claude Code from ritchiecarroll/go2cs. It costs 62 tokens per session (47,104 once invoked), scanned E, original, no licence file.

A troubleshooting guide for build, test, and approval results that may be misleading. It investigates false-green results, false reds, incomplete logs, empty outputs, concurrent sessions, and unsafe counting or launching.

In plain words
What is it for?
Use it to investigate suspicious gates, builds, or tests and to check whether logs, counts, sessions, and launch steps reflect what really happened.
Why use it?
A green result can be meaningless if nothing was actually tested, while a red result can come from broken instrumentation rather than the code. This guide helps find those cases before trusting the verdict.

This is ritchiecarroll/go2cs's own configuration. It tells Claude Code how to work on go2cs 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 go2cs 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 E, and why

gate-forensics scanned grade E with 2 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 today.

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 licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
