APEX Methodology Skill Skill

<objective> APEX Methodology drives the full Analyze -> Plan -> Execute -> eLicit -> eXamine workflow for any development task -- new features, bug fixes, refactors, hotfixes. It auto-detects the project type (Laravel, Next.js, React, Swift) and loads the matching framework-specific reference set, then walks through branch creation, brainstorming, codebase analysis, planning, TDD execution, expert self-review (eLicit), functional verification, and sniper validation (eXamine) through to PR creation.

It enforces the project's hard constraints throughout: every file within FUSE_SOLID_MAX_LINES (the hook ceiling), interfaces kept out of component files, SOLID principles, and a mandatory sniper pass after every Edit/Write (blocked by PostToolUse hooks until it runs). Three modes control how much is automatic: --auto (default, no prompts), --manual (step-by-step confirmation), and --skip-elicit (bypasses the self-review phase). </objective>

Current Task: $ARGUMENTS

APEX Methodology Skill

Analyze → Plan → Execute → eLicit → eXamine

Complete development workflow for features, fixes, and refactoring.

Step 0: Initialize Tracking (MANDATORY FIRST ACTION)

BEFORE anything else, initialize APEX tracking — see references/init-tracking.md for the exact command.

This creates .claude/apex/task.json (documentation consultation status) and .claude/apex/docs/ (consulted documentation summaries). The PreToolUse hooks will BLOCK Write/Edit until documentation is consulted.

Core Rules

File Size (ABSOLUTE)

🚨 Approaching `FUSE_SOLID_MAX_LINES` → Split by responsibility immediately
❌ NEVER exceed `FUSE_SOLID_MAX_LINES` (the hook blocks it)
📊 One responsibility per file; set no cap of your own

Interface Location

✅ src/interfaces/     (global)
✅ src/types/          (type definitions)
✅ Contracts/          (PHP/Laravel)
❌ NEVER in component files

Agent Usage

01-analyze:  explore-codebase + research-expert (PARALLEL)
04-validate: sniper (MANDATORY after ANY change)

NEVER

❌ Skip explore-codebase or research-expert
❌ Assume API syntax without verification
❌ Create files over `FUSE_SOLID_MAX_LINES`
❌ Put interfaces in component files
❌ Skip sniper after changes
❌ Merge without tests
❌ Large PRs (>400 lines)
