How does framework auto-detection work?

The skill scans your project root for signature files like composer.json, next.config.js, or Package.swift to automatically load framework-specific best practices and linting rules.

Can I use APEX for simple bug fixes?

Yes, APEX includes a dedicated Bug Fix Flow that prioritizes creating a failing test first, followed by a minimal fix and sniper validation.

What does the APEX acronym stand for?

APEX stands for Analyze (understand codebase), Plan (breakdown tasks), Execute (implement code), eLicit (expert self-review), and eXamine (validate with sniper agent).

What is the 'Sniper' agent mentioned in the workflow?

The Sniper agent is a mandatory automated validation process that runs after any change to verify code quality, check usages, run linters, and ensure zero errors before proceeding.

Why does this skill enforce a 100-line file limit?

The 100-line limit enforces strict modularity and the Single Responsibility Principle, making code significantly easier to test, review, and maintain.

Productivity & Workflow

Implements a systematic five-stage workflow for code development, analysis, and validation to ensure high-quality, modular software.

The APEX Methodology skill transforms Claude into a disciplined software architect by enforcing a rigorous Analyze-Plan-Execute-eLicit-eXamine workflow. It automates the entire development lifecycle—from branch creation to PR generation—while strictly enforcing best practices like SOLID principles and maintaining files under 100 lines. By integrating framework-specific guidance for Laravel, Next.js, and Swift, it ensures that every code change is validated by a 'sniper' agent and meets expert-level quality standards before deployment, making it ideal for complex features, bug fixes, and large-scale refactoring.
