Apex Methodology

It enforces the project's hard constraints throughout: files under 100 lines (split at 90), 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).

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

Core Rules

File Size (ABSOLUTE)

🚨 STOP at 90 lines → Split immediately
❌ NEVER exceed 100 lines
📊 Target: 50-80 lines per file

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 >100 lines
❌ Put interfaces in component files
❌ Skip sniper after changes
❌ Merge without tests
❌ Large PRs (>400 lines)
