Session Reflect

Analyze Claude Code session history to generate self-observation journals, detect goal drift, and surface hidden behavioral patterns. Outputs to Obsidian Vault.

Turn your Claude Code conversation history into a mirror.

This skill extracts your messages from Claude Code sessions, syncs them into your Obsidian Vault, and generates self-observation journals that help you understand your own patterns, priorities, and blind spots.

What It Does

Command	Purpose	Data Range
/reflect	Daily observation — what you're doing, how you're doing, emotional state	1-3 days
/reflect drift	Goal drift detection — stated goals vs actual behavior	7 days
/reflect emerge	Hidden pattern surfacing — unconscious preferences, avoidance patterns	14 days

Each command outputs a structured markdown file to your Obsidian Vault with observations and actionable suggestions.

How It Works

Claude Code Sessions (.jsonl)
        ↓
  extract_sessions.py (incremental sync, dedup, sanitize)
        ↓
  Obsidian Vault / 对话记录 / (daily digests)
        +
  Your own notes in the Vault
        ↓
  Agent analyzes both sources
        ↓
  Obsidian Vault / 自我观察 / (reflection journals)

Setup

1. Install

# Clone the repo
git clone https://github.com/yuiooo1102-droid/session-reflect.git ~/coding/session-reflect

# Or install as Claude Code command
mkdir -p ~/.claude/commands/reflect
cp commands/reflect/*.md ~/.claude/commands/reflect/

2. Initialize

python3 ~/coding/session-reflect/extract_sessions.py init
# You will be prompted to enter your Obsidian Vault path

3. Backfill History (Optional)

# By day
python3 ~/coding/session-reflect/extract_sessions.py backfill

# By week (recommended for long history)
python3 ~/coding/session-reflect/extract_sessions.py backfill --weekly

4. Use

# Sync new sessions (run before each reflect)
python3 ~/coding/session-reflect/extract_sessions.py sync

# Or just use the slash commands — they auto-sync
/reflect
/reflect drift
/reflect emerge

Requirements

• Python 3.10+
• Claude Code (sessions stored in ~/.claude/projects/)
