# Phase 01.5: Validate Context Files Exist [MANDATORY]

**Check for all 6 DevForgeAI context files:**

**Reference:** `parallel-context-loader.md` (STORY-112)

**Pattern:** Load all 6 files in a single message with 6 Read calls for implicit parallel execution.

**Time Savings:** 83% reduction (3000ms sequential → 500ms parallel)

```
# Single message with 6 Read calls - all execute in parallel
Read(file_path="devforgeai/specs/context/tech-stack.md")
Read(file_path="devforgeai/specs/context/source-tree.md")
Read(file_path="devforgeai/specs/context/dependencies.md")
Read(file_path="devforgeai/specs/context/coding-standards.md")
Read(file_path="devforgeai/specs/context/architecture-constraints.md")
Read(file_path="devforgeai/specs/context/anti-patterns.md")
```

**If ANY file is missing:**

```
Display: "❌ Context files missing - architecture setup required"
Display: "  Missing files prevent development (would cause technical debt from assumptions)"
Display: ""
Display: "Invoking spec-driven-architecture skill to create context files..."

Skill(command="spec-driven-architecture")

Display: "✓ Architecture skill completed"
Display: "Re-validating context files..."

# Re-read context files after architecture skill completes
[Execute same parallel Read operations above]
```

**STOP development until all context files exist.** This prevents technical debt from ambiguous assumptions.

**Token cost:** ~2,000 tokens (6 files × ~300 tokens each, read in parallel)
