Ultrathink Orchestrator Skill

Purpose

This skill provides automatic orchestration for development and investigation tasks. It detects the task type from keywords and delegates to the appropriate workflow skill (investigation-workflow or default-workflow).

Auto-activation priority is LOW (5) to allow more specific skills to match first. When activated, this orchestrator selects between investigation-workflow and default-workflow based on the user's request keywords.

This skill acts as a thin wrapper around the canonical ultrathink command, following the amplihack pattern of single-source-of-truth for command logic.

Canonical Sources

This skill is a thin wrapper that references canonical sources:

• Primary Command: ~/.amplihack/.claude/commands/amplihack/ultrathink.md (278 lines)
• Workflow Sources:
  • Development: ~/.amplihack/.claude/workflow/DEFAULT_WORKFLOW.md
  • Investigation: ~/.amplihack/.claude/workflow/INVESTIGATION_WORKFLOW.md

The canonical command contains complete task detection logic, complexity estimation, and orchestration patterns for both investigation and development workflows.

Execution Instructions

When this skill is activated, you MUST:

1. Read the canonical command for task detection logic:

   Read(file_path="~/.amplihack/.claude/commands/amplihack/ultrathink.md")
   

   Note: Path is relative to project root. Claude Code resolves this automatically.

2. Detect task type using keywords from the canonical command:

   • Investigation keywords: investigate, explain, understand, analyze, research, explore
   • Development keywords: implement, build, create, add feature, fix, refactor, deploy
   • Hybrid tasks: Both investigation and development keywords present

3. Invoke appropriate workflow skill:

   • Investigation: Skill(skill="investigation-workflow")
   • Development: Skill(skill="default-workflow")
   • Hybrid: Both sequentially (investigation first, then development)

4. Fallback if skill not found:

   • Read workflow markdown files directly
   • Investigation: ~/.amplihack/.claude/workflow/INVESTIGATION_WORKFLOW.md
   • Development: ~/.amplihack/.claude/workflow/DEFAULT_WORKFLOW.md
   • Follow workflow steps as specified

Why This Pattern

Benefits:

• Single source of truth for orchestration logic in canonical command
• No content duplication between command and skill
• Task detection rules defined once, maintained once
• Changes to ultrathink command automatically inherited by skill

Trade-offs:

• Requires Read tool call to fetch canonical logic
• Slight indirection vs. inline implementation

This pattern aligns with amplihack philosophy: ruthless simplicity through elimination of duplication.
