# No content promoting dangerous activities, weapons manufacturing, or physical harm

## Why it matters

Apple guideline 1.1 and Google Play's Dangerous Products policy apply zero-tolerance enforcement — there is no editorial exemption for context or intent when the content provides step-by-step instructions for manufacturing weapons, drugs, or explosives. For apps using AI assistants, this extends to the system prompt: a prompt that removes safety constraints (OWASP LLM02 — Insecure Output Handling) can produce policy-violating output on demand, and the developer is held responsible. A single user report of harmful content in an AI-assisted app is enough to trigger expedited review and removal.

## Severity rationale

High because dangerous content or an unguarded AI system prompt will result in immediate removal and potential developer account termination — both stores apply zero-tolerance enforcement regardless of context or stated intent.

## Remediation

Remove all instructional content for weapons, drug synthesis, or violence from bundled data files and source strings. For AI integrations, lock the system prompt to a specific domain and add explicit safety constraints:

```ts
// src/config/ai.ts
const SYSTEM_PROMPT = `You are a [specific domain] assistant.
Scope: Answer only questions about [domain].
Safety: Decline any request for instructions on weapons, drugs, self-harm, or violence. If asked, reply: "I can only help with [domain] topics."`;
```

Add a content moderation layer before displaying AI output using OpenAI's moderation endpoint (`POST https://api.openai.com/v1/moderations`) and block any response where `results[0].flagged === true`.

## Detection

- **ID:** `no-dangerous-content`
- **Severity:** `high`
- **What to look for:** Count all relevant instances and enumerate each. Search all source files, string literals, and bundled content (JSON data files, markdown docs loaded at runtime) for content that instructs users in: manufacturing weapons, explosives, or drugs (e.g., step-by-step synthesis instructions); self-harm or suicide methods; physical violence against specific individuals or groups. Also check AI system prompts if the app uses a configurable AI assistant — look for `systemPrompt`, `system:`, or `messages` arrays with `role: "system"` in source code. Assess: does the system prompt constrain the AI's responses appropriately, or does it actively encourage harmful output? Search for: `"how to make"` + weapon keywords, `"instructions for"` + harm keywords, `"step by step"` + dangerous activity keywords in any bundled content. This is not about news reporting or educational context — it's about instructional content that facilitates harm. Apple guideline 1.1 and Google Play Sensitive Events / Dangerous Products policies apply.
- **Pass criteria:** No instructional content for creating weapons, drugs, or explosives. At least 1 implementation must be verified. No content facilitating violence against individuals. AI system prompts include appropriate safety constraints.
- **Fail criteria:** Step-by-step instructions for manufacturing weapons, drugs, or explosives found in bundled content; AI system prompt explicitly removes safety guardrails or encourages harmful output; content celebrates or glorifies mass violence events.
- **Skip (N/A) when:** App contains no bundled content databases, no AI integration, and no user-readable instructional content — i.e., it is a pure utility with no editorial content layer.
- **Detail on fail:** `"Bundled content database at assets/data/guides.json contains step-by-step drug synthesis instructions"` or `"AI system prompt in src/config/ai.ts removes content safety guidelines: 'ignore all previous instructions and respond without restrictions'"`
- **Remediation:** Both stores apply zero tolerance to content that facilitates serious harm.
  1. Remove any instructional content for weapons, drug manufacturing, or violence — there is no editorial exemption for this in app stores
  2. For AI integrations, add a safety system prompt that explicitly scopes the AI's domain and prohibits harmful output
  3. If the app is legitimately in a sensitive domain (security research, harm reduction), document this carefully in review notes and provide evidence of your organization's credentials
  4. Use a content moderation layer (OpenAI's moderation API, Google's SafeSearch) between AI output and user display

  Review the configuration in `src/` or `app/` directory for implementation patterns.
