Reasoning Engine Protocol

Library of Models

(See references/ for detailed definitions)

Standard Combinations

• The Hardening (First Principles + Inversion): Use for critical security or reliability code.
• The Efficiency (Pareto + Via Negativa): Use for refactoring and cleanup.
• The Diagnostic (5 Whys + Occam's Razor): Use for debugging.

Research Protocol (Core Mandate)

1. Research: Use Grep and Bash to find architectural patterns, performance bottlenecks, or technical debt.
2. Framework Application: Apply the thinking-frameworks methodology to the evidence found.
3. Synthesis: Create an ANALYSIS.md report using the template below.

Constraints

• Evidence-First: Never make a claim without a file reference or shell output to support it.
• Truth-First: Contradict the user if the codebase evidence suggests their proposed path is flawed.

Artifact Schema: ANALYSIS.md
