AI Tool for Auditing Code: Plumb-Line Principles Checker

AI Tool for Auditing Code: Plumb-Line Principles Checker

The Plumb-Line Principles Checker is a specialized AI tool designed to audit code against the established "plumb-line principles." It identifies potential issues such as laundered uncertainty, boundary leaks, hardcoded priors, overstated maturity, outputs lacking recorded lineage, and unexplained baseline drift. This tool functions in a read-only capacity, providing reports rather than making automatic corrections.

What this skill does

• Audits a code diff or entire repository against specified "plumb-line principles."
• Detects issues like laundered uncertainty and boundary leaks.
• Generates reports on hardcoded priors and overstated maturity.
• Ensures outputs have documented lineage and addresses baseline drift.
• Requires the `reference/portable-principles.md` file to begin auditing.
• Scans the provided diff by default or the entire repository if no diff is given.
• Operates in read-only mode, dispatching subagents and consolidating their findings.

Who it is for

• Developers and teams utilizing Claude Code, Cursor, or Codex for AI coding projects.
• Quality assurance professionals aiming to maintain code integrity.
• Engineering teams focused on code security and compliance.

Use cases

• Conducting comprehensive code audits during continuous integration pipelines.
• Ensuring adherence to coding principles in collaborative development environments.
• Facilitating code reviews by highlighting potential areas of concern.

Technical details

• Utilizes the ai-tooling and aiapplication frameworks.
• Employs the plumb-line-audit tool for auditing processes.
• Operates with Claude Code, Cursor, and Codex environments.
• Initiates audits based on the presence and readability of the `reference/portable-principles.md` file.
