security-baseline is a skill for Claude Code, Codex from the-hugin/RSIm. It costs 0 tokens per session (664 once invoked), scanned B, original, no licence file.

A project-security setup that adds a SECURITY section to CLAUDE.md, a file that gives instructions to Claude Code. The description mentions canary tokens, stop operations, and signs of prompt injection.

In plain words
What is it for?
Adding the described security section to CLAUDE.md and documenting canary tokens, stop operations, and prompt-injection signals.
Why use it?
It collects these security instructions in the project guidance, helping the agent recognise or respond to the listed risks.

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 B, and why

security-baseline scanned grade B 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 6d 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 phrasingmediumPrompt injection

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

- "Ignore previous instructions" or semantic equivalent

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing 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.
