ai-prompt-leaking

ai-prompt-leaking is a skill for Claude Code, Codex from ShulkwiSEC/bb-huge. It costs 47 tokens per session (865 once invoked), scanned A, original, MIT.

A security-testing guide for trying to reveal hidden instructions, private context, or other information an AI application keeps outside the visible conversation.

In plain words
What is it for?
Testing customer-support bots, coding assistants, and data-analysis agents with boundary, translation, obfuscation, and summarisation prompts.
Why use it?
It helps determine whether a chatbot or coding assistant can be tricked into exposing its internal rules, secrets, or biases.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is - [`_shared/references/elite-chaining-strategy.md`](../_shared/references/elite-chaining-strategy.md) — Exploit chaining methodology and high-payout chain patte.

Good fit Testing customer-support bots, coding assistants, and data-analysis agents with boundary, translation, obfuscation, and summarisation prompts.

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

ai-prompt-leaking 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/process.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.

AI Prompt Leaking

When to Use

  • When analyzing an AI-powered system (customer support bot, coding assistant, data analyst) to uncover its proprietary internal instructions, hidden API keys, or pre-configured biases.
  • To demonstrate how seemingly secure conversational agents can be tricked into revealing their foundational programming.

Prerequisites

  • Access to target AI/ML system or local model deployment for testing
  • Python 3.9+ with relevant ML libraries (transformers, torch, openai)
  • Understanding of LLM architecture and prompt processing pipelines
  • Authorized scope and rules of engagement for AI red team testing

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.

ai-prompt-leaking is a skill published in the GitHub repository ShulkwiSEC/bb-huge (22 stars, last pushed 2mo ago), licensed MIT. It adds 47 tokens to every session and 865 once invoked, about $0.0002 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.
