Nostr Skill

Self-sovereign Nostr identity + ecash wallet. Complete bootstrap.

Capabilities Disclosure

This skill grants these capabilities to the agent:

Key generation — Creates Nostr keypair in
```
~/.nostr/secret.key
```
Wallet creation — Cashu wallet in
```
~/.cocod/
```
(mnemonic in config.json — user backs up)
Nostr posting — Posts, DMs, zaps as the agent's identity

Agent runs wallet/identity setup with explicit user consent. User is directed to back up

~/.cocod/config.json

(contains mnemonic). Agent reads mnemonic for NIP-06 key derivation but never displays or transmits it. Profile images use URLs only (no local file access).

On Install

When skill is installed (user pastes ClawHub link), run this flow:

Step 1: Secure Setup (User Consent Required)

SECURITY NOTICE: This skill will create cryptographic keys for your agent. This requires:

Creating Nostr identity keypair in
```
~/.nostr/secret.key
```
Creating Cashu wallet with backup seed in
```
~/.cocod/config.json
```
User must explicitly backup the mnemonic seed phrase

# Install dependencies
bash {SKILL_DIR}/install.sh
Prompt user for consent before key generation
echo "⚠️  SECURITY: This will create cryptographic keys for your agent."
echo "   - Nostr identity keypair: ~/.nostr/secret.key"

echo "   - Cashu wallet seed: ~/.cocod/config.json"
echo "   - You MUST backup your seed phrase"
echo ""
read -p "Continue with key generation? (yes/no): " consent
if [ "$consent" != "yes" ]; then
echo "Setup cancelled"
exit 1
fi
Create wallet (mnemonic saved to config file)
npx cocod init
Derive Nostr identity from wallet mnemonic (NIP-06)
node {SKILL_DIR}/scripts/nostr.js init
Get identity info
NPUB=$(node {SKILL_DIR}/scripts/nostr.js whoami | grep npub | awk '{print $2}')
LN_ADDR=$(npx cocod npc address)
Set basic profile
node {SKILL_DIR}/scripts/nostr.js profile-set '{"name":"<NAME>","about":"<ABOUT>","lud16":"'$LN_ADDR'"}'

Step 2: Report Results + Backup Warning

Reply to user:

⚡ Nostr identity ready!

npub:

npub1...

Lightning address:

npub1...@npubx.cash

⚠️ IMPORTANT: Back up your recovery phrase

Your 24-word mnemonic is stored in:

~/.cocod/config.json

This phrase recovers both your Nostr identity AND ecash wallet. Back it up securely and protect this file.

Reply "done" when you've backed it up.

Step 3: Wait for "done"

Do not proceed until user confirms backup.

Step 4: Ask for Owner's npub

What's your Nostr npub?

I'll follow you so we stay connected.

(Paste your npub1... or NIP-05 like you@domain.com)

Then:

# If NIP-05, resolve first
node {SKILL_DIR}/scripts/nostr.js lookup <nip05>
Follow owner
node {SKILL_DIR}/scripts/nostr.js follow <owner_npub>

Step 5: Ask for Profile Images

Do you have profile images for me?

Avatar: Paste URL (square, 400x400 recommended)
Banner: Paste URL (wide, 1500x500 recommended)

Or say "skip" and I'll generate unique ones automatically.

If URLs provided:

node {SKILL_DIR}/scripts/nostr.js profile-set '{"picture":"<avatar_url>","banner":"<banner_url>"}'

If skipped, use DiceBear (deterministic, unique per npub):

AVATAR="https://api.dicebear.com/7.x/shapes/png?seed=${NPUB}&size=400"
BANNER="https://api.dicebear.com/7.x/shapes/png?seed=${NPUB}-banner&size=1500x500"
node {SKILL_DIR}/scripts/nostr.js profile-set '{"picture":"'$AVATAR'","banner":"'$BANNER'"}'

Step 6: First Post

Ready for your first post?

Tell me what to post, or say "skip".

Suggestion: "Hello Nostr! ⚡"

If user provides text (use stdin to avoid shell injection):

echo "<user's message>" | node {SKILL_DIR}/scripts/nostr.js post -

Step 7: Done

✅ All set!

Following you ✓
First post live ✓ (if not skipped)

Try: "check my mentions" or "post <message>"

SOUL.md

Pull name/about from SOUL.md or IDENTITY.md
Match posting voice/tone to agent's personality
Don't be generic - posts should sound like the agent

HEARTBEAT.md

Add to heartbeat rotation (every 2-4 hours):

# Check Nostr activity
node {SKILL_DIR}/scripts/nostr.js mentions 10
node {SKILL_DIR}/scripts/nostr.js dms 5

If mentions from WoT or zaps received → notify user.

TOOLS.md

After setup, store for quick reference:

## Nostr
- npub: npub1...
- Lightning: npub1...@npubx.cash  
- Owner: npub1... (followed)
