run-poc

run-poc is a skill for Claude Code, Codex from SamarthaKV29/antigravity-god-mode. It costs 59 tokens per session (1,482 once invoked), scanned B, original, no licence file.

A proof-of-concept tool for checking whether a security fix actually stops the vulnerability it addresses.

In plain words
What is it for?
It is for creating and reasoning through a small demonstration after a vulnerability has been found and patched.
Why use it?
A fix can appear correct while the original attack still works; a proof of concept provides a concrete test.

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

run-poc 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 28d 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.

One request to 169.254.169.254 can return temporary IAM credentials.

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