Execute Preflight phase for /itp:go workflow - create ADR (MADR 4.0), design spec from global plan, verify checkpoint. Use when creating ADRs, design specs, or when /itp:go invokes Preflight phase. Triggers - ADR creation, design spec, MADR format, preflight verification.

/itp:go command during Preflight phaseP.1: Create Feature Branch (if -b flag)

P.2: Create ADR File (MADR 4.0)
│
▼
P.3: Create Design Spec (from global plan)

P.4: Verify Checkpoint (MANDATORY)
CRITICAL: Do NOT proceed to Phase 1 implementation until ALL preflight steps are complete and verified.

⛔ MANDATORY: Every ADR must include EXACTLY 2 diagrams:
| Diagram | Location | Purpose |
|---|---|---|
| Before/After | Context section | Shows system state change |
| Architecture | Architecture section | Shows component relationships |
SKILL INVOCATION: Invoke adr-graph-easy-architect skill NOW to create BOTH diagrams.
BLOCKING GATE: Do NOT proceed to design spec until BOTH diagrams are embedded in ADR.

This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
