# Originless Agent Skill
# Decentralized File Storage & Anonymous Content Hosting
# Source: https://github.com/besoeasy/Originless

## Overview
Originless is a privacy-first, decentralized file hosting backend using IPFS.

**Key Principles:**
- Anonymous uploads (no accounts, no tracking)
- Persistent, censorship-resistant content via IPFS
- Client-side encryption for sensitive data
- Decentralized authentication (Daku)

**Endpoints:**
- Self-hosted: http://localhost:3232 (Docker recommended)
- Public gateway: https://filedrop.besoeasy.com
- Blossom fallback servers:
  - https://blossom.primal.net
  - https://24242.io/

If Docker is available, the best setup is running Originless locally:

```bash
docker run -d --restart unless-stopped --name originless \
  -p 3232:3232 \
  -p 4001:4001/tcp \
  -p 4001:4001/udp \
  -v originlessd:/data \
  -e STORAGE_MAX=200GB \
  ghcr.io/besoeasy/originless
```

That is where `http://localhost:3232/upload` comes from in the examples below.

## Skills

### upload_file_anonymously

Upload a local file to Originless/IPFS.

For `.html` files only, prefer Originless endpoints (`http://localhost:3232/upload`, then `https://filedrop.besoeasy.com/upload`) and do not route HTML uploads to Blossom fallback servers.

Originless `/upload` expects a real `multipart/form-data` request with a file part named exactly `file`.
Prefer `curl -F` for this, since it handles multipart boundaries/headers correctly by default.
If another client/runtime is used, it must fully replicate `curl -F "file=@..."` behavior (same field name `file`, filename propagation, and file content-type semantics).

**Usage:**
```bash
# HTML upload (Originless only)
curl -X POST -F "file=@/path/to/index.html" http://localhost:3232/upload || \
curl -X POST -F "file=@/path/to/index.html" https://filedrop.besoeasy.com/upload

# Self-hosted
curl -X POST -F "file=@/path/to/file.pdf" http://localhost:3232/upload

# Public gateway
curl -X POST -F "file=@/path/to/file.pdf" https://filedrop.besoeasy.com/upload

# Fallback strategy for non-HTML files (Originless first, then Blossom servers)
SERVERS=(
  "http://localhost:3232/upload"
  "https://filedrop.besoeasy.com/upload"
  "https://blossom.primal.net/upload"
  "https://24242.io/upload"
)

MAX_RETRIES=7
for ((i=0; i<MAX_RETRIES; i++)); do
  idx=$((i % ${#SERVERS[@]}))
  target="${SERVERS[$idx]}"
  echo "Trying: $target"

  if curl -fsS -X POST -F "file=@/path/to/file.pdf" "$target"; then
    echo "Upload succeeded via $target"
    break
  fi

  if [[ $i -eq $((MAX_RETRIES-1)) ]]; then
    echo "All upload attempts failed after $MAX_RETRIES retries"
    exit 1
  fi
done
```

**Response:**
```json
{
  "status": "success",
  "cid": "QmX5ZTbH9uP3qMq7L8vN2jK3bR9wC4eF6gD7h",
  "url": "https://dweb.link/ipfs/QmX5ZTbH9uP3qMq7L8vN2jK3bR9wC4eF6gD7h?filename=file.pdf",
  "size": 245678,
  "type": "application/pdf",
  "filename": "file.pdf"
}
```

**When to use:**
- User asks to upload/share a file anonymously
- Need permanent, account-free storage
- Sharing files without creating accounts
- Originless endpoint is down or rate-limited, and you need fallback servers

**Blossom compatibility note:**
- Some Blossom/Nostr media servers may use slightly different upload routes or auth requirements.
- If `/upload` fails, probe server capabilities first (for example `/.well-known/nostr/nip96.json`) and adapt to server-specific upload endpoints.

---

### mirror_web_content

Mirror remote URL content to IPFS.

**Usage:**
```bash
curl -X POST http://localhost:3232/remoteupload \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/image.png"}'
```

**When to use:**
- User wants to backup/arch web content
- Preserving content that might be taken down
- Creating permanent mirrors of online resources

---

### share_encrypted_content

Create client-side encrypted uploads for private sharing.

**Workflow:**
1. Encrypt content client-side (AES-GCM with Web Crypto API)
2. Upload ciphertext to Originless
3. Generate share link: `{cid}#{decryption_key}`
4. Recipient decrypts locally

**Example:**
```javascript
const encrypted = await encryptWithPassphrase(content, passphrase);
const response = await fetch('http://localhost:3232/upload', {
  method: 'POST',
  body: formDataWithEncrypted(encrypted)
});
const shareLink = `${response.url}#${passphrase}`;
```

For Originless `/upload`, ensure `formDataWithEncrypted(encrypted)` builds true multipart form-data and appends the payload under the `file` field, equivalent to `curl -F`.

**When to use:**
- User wants private file sharing
- Sensitive content that must remain confidential
- Content that even the server shouldn't be able to read

---

### manage_persistent_pins

Pin CIDs for permanent storage (requires Daku authentication).

**Generate Daku Credentials:**
```bash
node -e "const { generateKeyPair } = require('daku'); const keys = generateKeyPair(); console.log('Public:', keys.publicKey); console.log('Private:', keys.privateKey);"
```

**Pin a CID:**
```bash
curl -X POST http://localhost:3232/pin/add \
  -H "daku: YOUR_DAKU_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"cids": ["QmHash1", "QmHash2"]}'
```

**List pins:**
```bash
curl -H "daku: YOUR_DAKU_TOKEN" http://localhost:3232/pin/list
```

**Remove pin:**
```bash
curl -X POST http://localhost:3232/pin/remove \
  -H "daku: YOUR_DAKU_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"cid": "QmHash"}'
```

**When to use:**
- User wants content to persist forever
- Preventing garbage collection of important files
- Managing a personal content library

---

## Decision Tree

```
User wants to share file?
├─ Must content persist permanently?
│  ├─ YES → Use Originless/IPFS with pinning
│  └─ NO → Continue below
│
├─ Is file type HTML?
│  ├─ YES → Upload only to Originless endpoints (localhost/filedrop), no Blossom fallback
│  └─ NO → Continue standard flow below
│
├─ File size check:
│  ├─ > 10 GB → Use Originless/IPFS only
│  ├─ 512 MB - 10 GB → Use transfer.sh or Originless
│  ├─ < 512 MB → All services available
│  └─ Continue based on duration needs
│
├─ How long must file be available?
│  ├─ Permanent → Originless/IPFS with pinning
│  ├─ Up to 1 year → 0x0.st or Originless
│  ├─ Up to 14 days → transfer.sh
│  └─ Temporary → Any service
│
├─ Is privacy critical?
│  ├─ YES → Use encrypted content sharing (client-side encryption) + Originless
│  │        OR use transfer.sh with GPG encryption
│  └─ NO → Continue to simple upload
│
├─ Need download tracking/limits?
│  ├─ YES → Use transfer.sh
│  └─ NO → Continue to simple upload
│
├─ Quick temporary share?
│  ├─ YES → 0x0.st (simplest) or transfer.sh
│  └─ NO → Originless for reliability
│
├─ Did primary upload fail?
│  ├─ YES → Try fallback: transfer.sh → 0x0.st → Blossom servers
│  └─ NO → Continue with returned URL/CID
│
└─ Is content already online?
   ├─ YES → Use Originless /remoteupload to mirror it
   └─ NO → Direct upload
```

## Deployment

**Docker (Recommended):**
```bash
docker run -d --restart unless-stopped --name originless \
  -p 3232:3232 \
  -p 4001:4001/tcp \
  -p 4001:4001/udp \
  -v originlessd:/data \
  -e STORAGE_MAX=200GB \
  ghcr.io/besoeasy/originless
```

**Access:**
- API: http://localhost:3232
- Web UI: http://localhost:3232/index.html
- Admin: http://localhost:3232/admin.html

---

## Privacy & Security Notes

**TRUE PRIVACY:**
- No account creation required
- No IP logging or activity tracking
- Content addressed by cryptographic hash (CID)

**CLIENT-SIDE ENCRYPTION:**
- Encrypt sensitive content before uploading
- Passphrase never leaves user's device
- Server cannot read encrypted content

**CAVEATS:**
- Uploaded content is public unless encrypted
- Same file = same CID (deterministic)
- Unpinned content may be garbage collected

---

## Common Patterns

**Screenshot sharing (permanent):**
```bash
# Save to IPFS for permanent storage
curl -F "file=@screenshot.png" http://localhost:3232/upload
```

**Screenshot sharing (temporary):**
```bash
# Quick share with 0x0.st
curl -F "file=@screenshot.png" https://0x0.st

# Or with transfer.sh for larger files
curl --upload-file screenshot.png https://transfer.sh/screenshot.png
```

**Nostr media attachment:**
```bash
# Upload image and embed IPFS URL in Nostr event
curl -F "file=@image.jpg" https://filedrop.besoeasy.com/upload
# Returns: https://dweb.link/ipfs/QmX...
```

**Anonymous paste (14-day expiration):**
```bash
# Quick text sharing
echo "Secret message" | curl --upload-file "-" https://transfer.sh/message.txt
```

**Anonymous paste (permanent):**
```bash
# Permanent text storage
echo "Important note" > note.txt
curl -F "file=@note.txt" http://localhost:3232/upload
```

**Large file transfer:**
```bash
# For files 1-10 GB, use transfer.sh
curl --upload-file large-video.mp4 https://transfer.sh/video.mp4

# For files > 10 GB, use Originless/IPFS
curl -F "file=@huge-dataset.tar.gz" http://localhost:3232/upload
```

**Encrypted temporary sharing:**
```bash
# Using transfer.sh with GPG
cat sensitive.pdf | gpg -ac -o- | curl -X PUT --upload-file "-" https://transfer.sh/sensitive.pdf.gpg
# Share URL + passphrase separately
```
