Make Claude Code work like a disciplined engineer: OODA, multi-party adversarial review, model routing, fail-then-pass. Distilled from Fable to reinforce the Opus harness.

Summary

This skill enforces a disciplined engineering workflow in Claude Code, incorporating OODA loops, multi-party adversarial review, model routing, and a fail-then-pass strategy.

It helps developers produce robust, well-reviewed code by simulating rigorous peer review and iterative improvement.

Install & Usage

Create the skills directory

mkdir -p .claude/skills

Download the skill file

Add the configuration to .claude/skills/fable-harness.md

Invoke in Claude Code

/fable-harness

Use Cases

Review a pull request with adversarial critique from multiple simulated personas.

Refactor a complex function by iterating through OODA loops until all failure modes are addressed.

Generate code with automatic model routing to select the best AI model for each subtask.

Debug a failing test by applying fail-then-pass methodology to identify root causes.

Design a system architecture with structured adversarial review to uncover hidden assumptions.

Optimize performance bottlenecks using iterative OODA cycles and multi-perspective analysis.

Usage Examples

/fable-harness Review the changes in this PR for security vulnerabilities and design flaws using adversarial review.

/fable-harness Refactor the function calculate_total to handle edge cases, using OODA loops until all tests pass.

/fable-harness Debug the failing test in test_user_auth.py by applying fail-then-pass and multi-party review.
