Decision Analysis Skill

{WORKSPACE} = timestamped run directory provided by the orchestrator.

Purpose

Separate decision points from defects. Undecided items (要検討, ?, 未確定) are not failures — they are choices that need to be made. This skill analyzes each decision point and recommends a direction.

When to Use

• Deliverable contains 要検討, ?, 未確定, TBD markers
• Items need option analysis rather than criticism
• Decision dependencies need to be mapped

Process

1. Read analyst items and preprocessed input
2. Scan for undecided markers using detection patterns from agent definition
3. For each undecided item:
   • Extract the decision point
   • Identify available options from context
   • Analyze pros/cons for each option
   • Recommend a direction based on project context
   • Assess urgency and dependencies
4. Map decision chains (which decisions block which)
5. Output structured recommendations

Integration with Pipeline

• Runs at: Phase 1.5 (after Analyst, before Critic)
• Critic interaction: The critic receives the decision advisor's output and MUST:
  • Tag findings that overlap with undecided items as "is_undecided": true
  • Not assign HIGH/MEDIUM/LOW severity to undecided items
  • Instead reference the UNDECIDED-XXX id for the decision advisor's analysis
• QA interaction: QA validates decision recommendations through all 5 consulting lenses
• Report: Undecided items appear in a dedicated section with option comparison UI

Quality Checklist

• All 要検討/？/未確定 markers identified
• Each has minimum 2 options with pros/cons
• Decision chains mapped (blocking relationships)
• Urgency levels assigned with rationale
• Recommendations have confidence levels
• Impact of delay stated for each
