python-exploitation

python-exploitation is a skill for Claude Code, Codex from Lu1sDV/skillsmd. It costs 125 tokens per session (2,163 once invoked), scanned A, original, no licence file.

A Python security-exploitation skill for testing sandbox escapes, restricted code execution, unsafe deserialization, and template-injection paths.

In plain words
What is it for?
It is for testing Python sandboxes and blacklists, recovering restricted built-ins, examining pickle, marshal, or PyYAML deserialization, and investigating Jinja2 or other template-injection cases.
Why use it?
It helps investigate whether Python restrictions or unsafe input handling can be bypassed to execute unintended code.

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

python-exploitation scanned grade A 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 1mo 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.

Expected in a hook, worth knowing in a rule or an instructions file.

What ships with it

4 files 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.

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.
