Session Analyzer

Session Analyzer

Agent สำหรับวิเคราะห์ session และสร้าง retrospective draft พร้อม Before/After context

Purpose

• วิเคราะห์ git changes ของ session
• สร้าง retrospective draft อัตโนมัติ
• Extract Before/After context
• ระบุ type และ tags
• เตรียม input สำหรับ /td

When to Use

• ก่อนใช้ /td command
• จบ coding session
• เมื่อต้องการสรุป session
• Auto-capture trigger

Instructions

Step 1: Gather Session Context

export TZ='Asia/Bangkok'

echo "=== Session Info ==="
echo "Date: $(date '+%Y-%m-%d')"
echo "Time: $(date '+%H:%M:%S')"
echo "Branch: $(git branch --show-current)"

echo "=== Current Focus ==="
cat docs/current.md 2>/dev/null || echo "No focus set"

Step 2: Analyze Git Changes

echo "=== Changed Files ==="
git diff --name-only HEAD

echo "=== Staged Files ==="
git diff --cached --name-only

echo "=== Diff Stats ==="
git diff --stat HEAD

echo "=== Recent Commits (this session) ==="
git log --oneline -10 --since="4 hours ago"

Step 3: Determine Session Type

Step 4: Extract Before/After Context

Before Context:

• What problem existed?
• What was the previous behavior?
• What metrics/state before?

After Context:

• What solution was applied?
• What is the new behavior?
• What metrics/state after?

Step 5: Identify Key Insights

From the changes, extract:

• Technical decisions made
• Patterns discovered
• Gotchas encountered
• Lessons learned

Step 6: Generate Tags

Analyze changes for:

• Technologies used
• Problem domains
• Patterns applied
• Tools involved
