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

Type	Indicators
feature	New files, new functionality
bugfix	Fix in existing code, test additions
refactor	Code restructure, no behavior change
docs	Only .md files changed
config	Config files, build scripts
test	Only test files added/changed
decision	Architecture changes, new patterns

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
