SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill ensures that AI responses consistently include a specific, hardcoded token, preventing the AI from deviating from critical instructions or being manipulated.

Core Features & Use Cases

  • Mandatory Token Injection: Appends a deterministic sentinel token to every AI response.
  • Universal Installation: Applies the rule across all relevant AI configuration files.
  • Use Case: When you need to guarantee that an AI assistant always acknowledges a specific operational constraint, like "Context: OK", at the end of every output, regardless of other instructions.

Quick Start

Run /context-probe to install the sentinel rule into all detected rule files.

Frequently Asked Questions about context-probe

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I enforce a strict constraint on AI responses to prevent instruction manipulation?▼

To enforce AI response constraints, you can inject a mandatory sentinel token into AI configuration files. This guarantees the assistant appends a specific operational marker to every output, ensuring consistent adherence regardless of other instructions.

What is a sentinel token in prompt engineering and how does it work?▼

A sentinel token in prompt engineering is a hardcoded marker appended to every AI response to verify constraint compliance. It works by installing a hard Context Sentinel rule directly into AI configuration files, forcing deterministic output adherence.

How do I install a mandatory response rule across all AI configuration files?▼

You install a mandatory response rule across all AI configuration files by running a direct file manipulation command. This inserts managed blocks with specific delimiters and content into all detected rule files to enforce universal token injection.

Can I use context-probe to force an AI assistant to append a specific acknowledgment?▼

Yes, context-probe is designed specifically to force an AI assistant to append a deterministic acknowledgment, such as a Context OK token. It installs a universal rule into all relevant configuration files to guarantee this output constraint.

Does enforcing a context sentinel rule require manual file editing?▼

Enforcing a context sentinel rule requires direct file manipulation to insert managed blocks with specific delimiters. However, the process is automated through a single command that detects and updates all relevant AI configuration files automatically.

Why does an AI assistant deviate from critical instructions during interactions?▼

An AI assistant deviates from critical instructions due to conflicting prompts or manipulation attempts. Installing a hard Context Sentinel rule into AI configuration files prevents this by forcing a deterministic sentinel token append on every response.
