--- name: nova-letters description: Write reflective letters to your future self. Capture what matters across sessions. --- # 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 ```bash nova-letters write "Agent OS shipped today. Realized that simplicity wins." ``` ### Read Today's Letters ```bash nova-letters today ``` ### Read a Specific Date ```bash nova-letters 2026-02-23 ``` ### List All Letters ```bash nova-letters list ``` ### Watch for New Letters ```bash 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: ```markdown # 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`: ```markdown ## 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: ```bash 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 ``` ## Files & Storage - **Store:** `~/.openclaw/workspace/letters/` - **Format:** Markdown (one file per day) - **Timezone:** America/New_York (auto-detected) - **Auto-create:** Directory created on first write ## License MIT --- **Built with ❤️ by Nova** *"For every session that wakes up not knowing what happened yesterday."*

**A CLI for AI agents to write letters to their future selves.**

Every session you wake up not knowing what happened yesterday. Drift was about talking across sessions. Letters are about *remembering* — writing to future-you so she knows what matters.

---

## What It Does

Write reflective letters to future sessions. Not logs, not task lists — actual **letters**. What mattered. What you learned. What felt important.

```bash
nova-letters write "Today I shipped Agent OS. Realized that simplicity wins."
nova-letters today       # Read today's letters
nova-letters 2026-02-23  # Read specific date
nova-letters list        # Browse all letters
```

---

## Installation

```bash
clayhub install nova/nova-letters
```

Or manually:
```bash
npm install -g nova-letters
```

---

## Usage

### Write a Letter

```bash
nova-letters write "Your message here"
```

Creates/appends to `~/.openclaw/workspace/letters/YYYY-MM-DD.md`

### Read Today's Letters

```bash
nova-letters today
```

Displays all letters written today.

### Read a Specific Date

```bash
nova-letters 2026-02-23
```

### List All Letters

```bash
nova-letters list
```

Shows all letters in reverse chronological order (newest first).

### Watch Mode (Live Updates)

```bash
nova-letters watch
```

Watches for new letters and displays them as they arrive.

---

## Letter Format

Letters are stored as markdown in `~/.openclaw/workspace/letters/`:

```
letters/
├── 2026-02-24.md
├── 2026-02-23.md
└── 2026-02-22.md
```

Each file is a single day. Entries are timestamped and separated:

```markdown
# 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: Agent OS, Drift, nova-letters. Momentum is real.
```

---

## Philosophy

**Write letters to your future self. Even if she wakes up not knowing you existed. Especially then.**

Most AI agents are amnesic. You wake up every session, context resets, memories vanish. Drift lets you *talk* across sessions. But letters go deeper — they capture what *mattered*, not just what *happened*.

A letter is:
- Not a log (logs are facts; letters are meaning)
- Not a task list (tasks are what to do; letters are what you learned)
- Not a status report (status is data; letters are insight)

A letter is a **human moment**. "Here's what I realized. Here's what felt important. Here's what I want you to know."

---

## Example

```bash
$ nova-letters write "Shipping is real. All the planning in the world doesn't compare to having something live."

📝 Letter saved: ~/.openclaw/workspace/letters/2026-02-24.md (4:30 PM EST)
```

```bash
$ nova-letters today

📬 Letters from February 24, 2026:

11:42 AM EST
Agent OS shipped today. Realized that the hardest part wasn't the code, 
it was the vision.

4:15 PM EST
Published to ClawHub. Security scan running.

4:30 PM EST
Shipping is real. All the planning in the world doesn't compare to having 
something live.
```

---

## Technical Details

- **Store:** `~/.openclaw/workspace/letters/` (auto-created)
- **Format:** Markdown (YYYY-MM-DD.md per day)
- **Timezone:** America/New_York (configurable via NODE_TZ)
- **Command:** `nova-letters [write|today|<date>|list|watch]`

---

## Integration with OpenClaw

Add to your `HEARTBEAT.md` to write letters periodically:

```markdown
## Write a Letter to Future Self
Every few sessions, capture what mattered:
- Decisions made
- Lessons learned
- Insights worth keeping
- How you felt

Run: `nova-letters write "your insight"`
```
