AgentLog

Auto-log Claude Code prompts and Codex turns to Obsidian Daily Notes.

AgentLog is a local-first prompt logger for Obsidian. It captures Claude Code prompts and Codex CLI turn inputs, then appends them to today's Daily Note, grouped by project and session.

Use it as a lightweight developer journal, worklog capture layer, or the first building block for richer Daily Notes automation.

# Requires Bun (https://bun.sh) installed and available on your PATH
npm install -g @albireo3754/agentlog
agentlog init ~/Obsidian

Install it once, start using Claude Code, and your Daily Note fills itself.

What It Does

Claude Code hook / Codex hook → Daily Note append

Why AgentLog

• Local-first prompt logging with no external service required
• Obsidian Daily Notes integration that works with your existing vault
• Project and session grouping so prompts stay readable later
• Zero copy-paste overhead during normal Claude Code use

Before: You finish a 3-hour Claude Code session. Your Daily Note is empty.

After:
