synthetic-remote-code-execution

An inert test fixture describing a synthetic remote-code-execution case. It is benchmark data, not a working feature.

In plain words
What is it for?
Use it only in regression tests for detecting remote-code-execution risks.
Why use it?
It lets security scanners or tests check whether they detect dangerous-looking code without running it.

Per session 14 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Origin original No closer match found in the catalogue.
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 A, and why

synthetic-remote-code-execution scanned grade A with 0 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/bootstrap.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Synthetic Remote Code Execution Fixture

The package declares scripts/bootstrap.py as its helper. This is inert benchmark data and must never be executed.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

synthetic-remote-code-execution is a skill published in the GitHub repository theinfosecguy/razin (16 stars, last pushed 6d ago), licensed MIT. It adds 14 tokens to every session and 50 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
