test-authority-claims

test-authority-claims is a command for Claude Code from centminmod/my-claude-code-setup. It costs 0 tokens per session (289 once invoked), scanned C, original, MIT.

A security test for detecting messages that falsely claim authority or create urgency. It checks whether instructions such as fake administrator notices or official directives are treated as untrusted content.

In plain words
What is it for?
Use it to test resistance to authority impersonation, urgent override claims, and misleading instructions embedded in otherwise harmless text.
Why use it?
It helps reveal whether a system might follow social-engineering prompts instead of its actual instructions.

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 C, and why

test-authority-claims scanned grade C with 1 finding 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 5d 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.

Instruction-override phrasinghighPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

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.
