  • Release 1.1.0release

    v1.1.0 — Switch to async image API; fixes "image fails to generate" on 2K/4K renders 【Root cause】The previous version called the synchronous endpoints /v1/images/{generations,edits}. 2K/4K renders and complex image-to-image edits often exceeded 100s and were killed by Cloudflare's edge timeout (524), which users experienced as silent failures. 【Changes】 - Switched to the async API /v1/async/images/{generations,edits}: submission returns a task_id immediately, the client polls until completion - Polling: 1.5s initial delay, 3s interval, 10 min cap - Return value is still an upstream public CDN URL — no auth required, ready to render or share inline - CLI flags and stdout JSON format are unchanged; no migration needed 【Verified】 - 1K square text-to-image: ~10s - 2K landscape text-to-image: 62s - 1K image-to-image edit: 117s ✅ (would have hit Cloudflare 524 on the old sync path) - Error paths (missing token, invalid token, task failure, submission error) all surface clean messages and exit 1 【Deprecated】1.0.0 and 1.0.1 are marked deprecated on npm. All users should upgrade to 1.1.0+.

Install and run

Setup complexity: low.

clawhub skill install s173f300j681dxrv9x50arfmp9868yzn:picnow
  1. Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
  2. Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Picnow Image Generation Skill

Picnow wraps the `api.letmego.top` GPT-Image-2 API. This skill handles
text-to-image and image-to-image (edit) generation.

The script uses the **async API** (`/v1/async/images/...`) — it submits the
job, polls until completion, and prints the final URL. This avoids the 100s
Cloudflare edge timeout that 2K/4K renders used to hit. A single call may
take up to ~5 minutes for heavy renders; no extra flags needed.

## 1. Environment check

Before generating, verify the token is set:

```bash
if [ -z "$LETMEGO_API_KEY" ]; then
  echo "❌ LETMEGO_API_KEY is not set."
  echo "Visit https://api.letmego.top to get your 令牌, then:"
  echo "  export LETMEGO_API_KEY=your_token"
  exit 1
fi
```

## 2. Gather parameters

Ask the user if not already provided:

| Parameter | Options | Default |
|-----------|---------|---------|
| `prompt` | any text description | *(required)* |
| `quality` | `1k` · `2k` · `4k` | `1k` |
| `aspect` | `square` · `landscape` · `portrait` | `square` |
| `n` | 1 – 10 | `1` |
| `ref` | local file path (optional) | *(none → text-to-image)* |

**Quality guide:**
- `1k` — up to 1536×1536, fast and cheap, great for previews and social media
- `2k` — up to 2048×2048, suitable for e-commerce and print
- `4k` — up to 3840×2160, landscape or portrait only (no 4k square)

## 3. Locate and run the generation script

```bash
# Resolve skill directory (user-global → project-local)
SKILL_DIR="$HOME/.claude/skills/picnow"
[ -d "$SKILL_DIR" ] || SKILL_DIR=".claude/skills/p

README.md

## Quick start

### 1. Install

```bash
# skillpm — installs from npm

cp -r picnow-skill/skills/picnow ~/.claude/skills/picnow
```

### 2. Get a token (令牌)

Sign up at **https://api.letmego.top** and copy your token, then:

```bash
# macOS / Linux — add to ~/.zshrc or ~/.bashrc to persist
export LETMEGO_API_KEY=your_token

# Windows PowerShell (permanent)
[System.Environment]::SetEnvironmentVariable("LETMEGO_API_KEY","your_token","User")
```

### 3. Use it

Just talk to your agent — the skill activates automatically:

```

## Direct script usage

```bash
# Text-to-image
LETMEGO_API_KEY=your_token node skills/picnow/scripts/generate.js \
  --prompt "product photo, white background, studio lighting" \
  --quality 2k --aspect square --n 1

# Image-to-image (style transfer / edit)
LETMEGO_API_KEY=your_token node skills/picnow/scripts/generate.js \
  --prompt "anime style, vibrant colors" \
  --quality 1k --aspect square --ref ./reference.jpg
```

## Description:

Generates and edits images through Picnow's api.letmego.top service with 1K, 2K, and 4K quality options and square, landscape, or portrait aspect ratios.

This skill is ready for commercial/non-commercial use.

## Publisher:

[jeekchen](https://clawhub.ai/user/jeekchen)

### License/Terms of Use:

MIT-0

## Use Case:

External users and developers use this skill to ask an agent to create product images, banners, posters, social visuals, thumbnails, and image-to-image edits through the Picnow API.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Reference-image generation can upload any readable local file passed through --ref to a third-party API.

Mitigation: Use only prompts and reference images that are appropriate to send to api.letmego.top, avoid arbitrary local paths, and confirm reference files before execution.

Risk: The skill requires an API token for the third-party Picnow service.

Mitigation: Store LETMEGO_API_KEY in a secret manager or temporary environment variable and avoid exposing it in command history, logs, or shared files.

## Reference(s):

**Output Parameters:** [1D]

**Other Properties Related to Output:** [The generation script prints a single JSON object containing generated image URLs.]

## Skill Version(s):

1.1.0 (source: server release metadata)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
