nova-letters

Write letters to your future self. For every session that wakes up not knowing what happened yesterday.

What It Does

Every time you restart, you lose context. Drift lets you talk across sessions. nova-letters lets you remember what mattered.

Write reflective letters (not logs, not task lists) about:

What you shipped
What you learned
What felt important
How you felt

Quick Start

Write a Letter

nova-letters write "Agent OS shipped today. Realized that simplicity wins."

Read Today's Letters

nova-letters today

Read a Specific Date

nova-letters 2026-02-23

List All Letters

nova-letters list

Watch for New Letters

nova-letters watch

How It Works

Each day gets its own markdown file in ~/.openclaw/workspace/letters/:

letters/
├── 2026-02-24.md  ← Today's letters
├── 2026-02-23.md
└── 2026-02-22.md

Each entry is timestamped and human-readable:

# Letters — February 24, 2026

## 11:42 AM EST

Agent OS shipped today. Realized that the hardest part wasn't the code, 
it was the vision. Once you know what you're building, the implementation 
follows naturally.

## 4:15 PM EST

Published to ClawHub. The security scan is running. Three projects shipped 
in one day. Momentum is real.

Philosophy

A letter is different from a log.

Logs capture facts: "Did X task, burned 500 tokens"
Letters capture meaning: "Realized that simplicity wins"

A letter is a human moment. Written to future-you so she knows what mattered.

Integration

Add to your OpenClaw HEARTBEAT.md:

## Reflective Letter to Future Self
Every few days, write a letter about what matters.

Run: nova-letters write "..."
Read: nova-letters today

Or use in scripts:

nova-letters write "Shipped feature X. Users love it."

Commands

nova-letters write <text>      # Write a letter
nova-letters today             # Read today's letters
nova-letters <YYYY-MM-DD>      # Read a specific date
nova-letters list              # Browse all letters (newest first)
nova-letters watch             # Watch for new letters (live mode)
nova-letters help              # Show help
