• ↩️ Easy Restore: Your original status line is backed up and can be restored anytime

Architecture

How Status Line Works

1. Intercepts prompts submitted in Claude Code
2. Analyzes via the local Claude Code latest prompt with relevant session context.
3. Provides strategic guidance and pushes you to ship
4. Displays actionable feedback in the Claude Code status line

Example Output

Setup

1. Run npx vibe-log-cli
2. Select "Configure prompt coach status line"
3. Choose coach personality
4. (Optional) Enable ccusage token metrics display
5. Prompts will be analyzed locally in Claude Code

Note: Installation automatically backs up your current status line (if any). When you uninstall vibe-log, your original configuration is instantly restored.

Auto-Sync

What is Auto-Sync

Claude Code hooks and Codex hooks allow Vibe-Log to automatically sync local sessions in the background. Claude Code auto-sync is stable. Codex auto-sync is experimental and sync-only.

What are hooks?

• Small commands that run at specific moments in Claude Code or Codex

• They work silently in the background (you won't notice them)

Which Claude Code hooks do we use?

📍 SessionStart - Syncs previous sessions when you start/resume work (Triggers: startup, resume, clear commands)

📦 PreCompact - Syncs full session before context compression (Triggers: manual or automatic context cleanup)

Why we recommend both:

✓ SessionStart ensures nothing is lost between sessions

✓ PreCompact syncs everything before Claude compresses context

Which Codex hooks do we use?

📍 SessionStart - Syncs recent Codex sessions when work starts

🔚 Stop - Syncs after Codex finishes responding

Codex hooks write Vibe-Log commands to Codex hooks.json and enable [features].codex_hooks = true in Codex config.toml. Vibe-Log does not install Codex prompt coach or statusline hooks.

Setup Auto-sync

1. Run npx vibe-log-cli
2. Authenticate with your Github account
3. Enable auto-sync via CLI menu
