  Systematic development workflow: Analyze → Plan → Execute → eLicit → eXamine.
  Use for ANY development task: features, bug fixes, refactoring, hotfixes.
  Triggers: "implement", "create", "build", "fix", "add feature", "refactor", "develop".
  Auto-detects project type (Laravel, Next.js, React, Swift) and loads framework-specific references.
  Enforces: files <100 lines, interfaces separated, SOLID principles, expert self-review, sniper validation.
  Modes: --auto (default), --manual, --skip-elicit

**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.**

### Skills Integration

| Phase | Skill | Invocation |
|-------|-------|------------|
| 00.5 | `brainstorming` | Questions → alternatives → design doc → approval |
| 03 | `tdd` | RED (test) → GREEN (code) → REFACTOR cycle |
| 03.7 | `verification` | Re-read request → check criteria → confirm resolution |

| **00** | `references/00-init-branch.md` | Create feature branch |
| **01** | `references/01-analyze-code.md` | Explore + Research (APEX A) |
| **02** | `references/02-features-plan.md` | TaskCreate planning (APEX P) |
| **03** | `references/03-execution.md` | Implementation (APEX E) |

## Core Rules

### File Size (ABSOLUTE)

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

### Interface Location

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

### Agent Usage

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

---

## NEVER

```text
❌ 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)
```
