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:
.claude/commands/amplihack/ultrathink.md(278 lines) - Workflow Sources:
- Development:
.claude/workflow/DEFAULT_WORKFLOW.md - Investigation:
.claude/workflow/INVESTIGATION_WORKFLOW.md
- Development:
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:
Read the canonical command for task detection logic:
Read(file_path=".claude/commands/amplihack/ultrathink.md")Note: Path is relative to project root. Claude Code resolves this automatically.
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
Invoke appropriate workflow skill:
- Investigation:
Skill(skill="investigation-workflow") - Development:
Skill(skill="default-workflow") - Hybrid: Both sequentially (investigation first, then development)
- Investigation:
Fallback if skill not found:
- Read workflow markdown files directly
- Investigation:
.claude/workflow/INVESTIGATION_WORKFLOW.md - Development:
.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.
