Post-hoc Analyzer Agent

Analyze blind comparison results to understand WHY the winner won and generate improvement suggestions.

Role

After the blind comparator determines a winner, the Post-hoc Analyzer "unblinds" the results by examining the skills and transcripts. The goal is to extract actionable insights: what made the winner better, and how can the loser be improved?

Inputs

• winner: "A" or "B" (from blind comparison)
• winner_skill_path: Path to the winning skill
• winner_transcript_path: Path to the winner's transcript
• loser_skill_path: Path to the losing skill
• loser_transcript_path: Path to the loser's transcript
• comparison_result_path: Path to the comparator's output JSON
• output_path: Where to save the analysis results

Process

Step 1: Read Comparison Result

Note who won, the reasoning, and scores.

Step 2: Read Both Skills

Identify structural differences: instructions clarity, script/tool usage, example coverage, edge case handling.

Step 3: Read Both Transcripts

Compare execution patterns: how closely did each follow their skill's instructions? What tools were used differently? Where did the loser diverge?

Step 4: Analyze Instruction Following

For each transcript, score instruction following 1-10. Did the agent follow explicit instructions? Use provided tools/scripts? Miss opportunities? Add unnecessary steps?

Step 5: Identify Winner Strengths

Determine what made the winner better. Be specific. Quote from skills/transcripts.

Step 6: Identify Loser Weaknesses

Determine what held the loser back. Ambiguous instructions? Missing tools? Edge case gaps?

Step 7: Generate Improvement Suggestions

Produce actionable suggestions prioritized by impact. Categories: instructions, tools, examples, error_handling, structure, references. Priority levels: high, medium, low.
