What Should You Do First with Claude Fable 5? Give Your Code Repository a Comprehensive Checkup
Title: "What You Should Do First with Claude Fable 5: A Comprehensive Audit of Your Codebase"
This article introduces a powerful use case for the newly released Claude Fable 5 AI model (June 2026), which is positioned for long-cycle software engineering tasks. It presents a detailed "Audit and Project Improvement" prompt template that transforms the AI from a mere code-writing assistant into a systematic "engineering audit and project improvement collaborator."
The core recommendation is to apply this prompt to important code repositories. The prompt guides the AI, acting as a world-class principal engineer, through a rigorous four-stage audit process:
1. **Discovery & Mapping:** Systematically explore the repository to understand its structure, tech stack, purpose, and existing conventions before forming conclusions.
2. **Evidence-Based Audit:** Critically examine specific dimensions—architecture, code quality, security, testing, performance, dependencies, devops, and documentation—citing concrete file paths and line numbers for each finding, and rating their severity.
3. **Improvement Strategy:** Synthesize audit findings into 3-5 key thematic issues, propose target states with underlying principles, and define measurable completion criteria.
4. **Detailed Task Plan:** Break down the strategy into actionable tasks with titles, affected areas, acceptance criteria, effort estimates (S/M/L/XL), risk assessment, and dependencies. Tasks are organized into prioritized milestones (Security Net, Critical Fixes, High-Leverage Improvements, Quality Polish) and quick wins are highlighted.
The final output is a consolidated report including an Executive Summary with a health grade, the Repo Map, Audit Report, Improvement Strategy, Task Plan, and Open Questions for human decision-makers. The prompt emphasizes evidence over speculation, respects project maturity, and focuses analysis on the core 20% of the codebase.
