pattern8

Overview

Pattern 8 acts as a governance and enforcement layer for AI agents operating within software development projects. It separates project rules (the 'Law' comprising SKILL definitions, checklists, and templates) from execution enforcement (the 'Police' runtime engine comprising security guards, tool wrappers, and reviewers). By hiding specific audit and security criteria from the agent and utilizing MCP stdio servers alongside pre-commit hooks, P8 prevents hallucination, unauthorized system commands, and context degradation.

Capabilities

• ▸OS-level command blacklisting and interception via security guard
• ▸Automated output auditing and retry loops through static rule engines
• ▸Model Context Protocol (MCP) server integration
• ▸Structured SKILL pipeline execution with inversion checklists and output templates
• ▸Pre-commit integrity checking and secret scanning hooks
• ▸Multi-language support (English and Chinese rule generation)

Best for

Enforcing strict adherence to step-by-step development pipelines for PRDs, bug fixes, code reviews, and refactoring., Preventing AI agents from executing dangerous OS commands via regex-based command blacklisting and tool wrappers., Eliminating output hallucinations and freestyle code generation through strict template compliance and automated review-and-retry loops., Forcing agents to ask clarifying questions instead of guessing when required information is missing from a prompt.

Works with

Security considerations

P8 includes a built-in security guard with regex blacklisting and hidden security constraint files to prevent agents from executing destructive commands or bypassing auditing rules.
