Content News Thai
Generate news-style post images with Thai text overlay + captions for social media.
Setup (first time only)
Run the setup script to install dependencies (canvas, Thai fonts):
bash \x3CSKILL_DIR>/scripts/setup.sh
On Docker/VPS this installs: libcairo2, libpango, Thai fonts (Kanit, Prompt, Sarabun). On macOS: uses Homebrew for cairo/pango.
Generate News Image
cd \x3CSKILL_DIR>/scripts && node gen-news.mjs '\x3Cjson>'
Parameters
| Param | Required | Description |
|---|---|---|
| headline | ✅ | Main headline (Thai/English, auto-wraps) |
| sub | Sub-headline text | |
| badge | Badge label (default: "AI NEWS") | |
| badgeColor | Badge color (default: "#CC0000") | |
| bgImage | Background image path or URL | |
| bgColor | Fallback bg gradient color (default: "#0a0a1a") | |
| source | Source attribution at bottom | |
| output | ✅ | Output file path (.jpg) |
| brandName | Watermark text (bottom-right) | |
| accentColor | Bottom bar color (default: "#CC0000") |
Example
cd \x3CSKILL_DIR>/scripts && node gen-news.mjs '{"headline":"AI กำลังเปลี่ยนวงการค้าปลีก","sub":"ยอดขายพุ่ง 40% ใน 6 เดือน","badge":"BREAKING NEWS","source":"Reuters • มี.ค. 2026","brandName":"MY BRAND","output":"/tmp/news_post.jpg"}'
Output: JSON {"status":"done","output":"/tmp/news_post.jpg","size":"1080x1350","type":"image"}
Background Image
Two approaches:
- With bgImage — provide a path/URL to a photo. The script covers it with dark gradient for text readability.
- Without bgImage — generates a dark gradient background with subtle grid pattern. Good for text-focused posts.
For best results, generate a background image first (use the AI model's image generation), save it, then pass the path as bgImage.
Workflow: Full Content Set
When asked to create a complete content set:
- Write headline + sub — short, punchy, Thai-friendly
- Generate background — use AI image gen or use bgColor for clean look
- Run gen-news.mjs — creates 1080x1350 image with Thai text overlay
- Write caption — storytelling style, short sentences, end with engaging question
- Return — image path + caption to user
Caption Style Guide
- Open with a scroll-stopping hook (short, impactful)
- Tell the story with short sentences, reveal layer by layer
- Include the brand's perspective/opinion
- End with: impact summary → specific question → soft share cue (if appropriate)
- Add 3-5 relevant hashtags
- Do NOT end with generic "คิดเห็นยังไงคอมเมนต์มา"
Troubleshooting
- "canvas" error → rerun setup.sh
- Fonts look wrong → check assets/fonts/ has .ttf files, rerun setup.sh
- bgImage not found → use absolute path or URL
Usage Guidance
This skill appears to do what it claims: generate Thai news-style images. Before installing or running setup.sh, consider: 1) setup.sh installs system packages (apt/brew), npm dependencies (canvas) and downloads fonts from GitHub — run it in a controlled environment (docker container or VM) if you want to avoid changing your host. 2) The script copies fonts to a system font directory and may use sudo; expect system-wide changes. 3) gen-news.mjs can load bgImage URLs (it may fetch remote images) and writes output files to disk — only pass URLs/paths you trust and choose a safe output directory. 4) npm canvas requires native build tools; review the package.json and the npm install output. If you are comfortable with those actions, the skill is coherent and reasonable for its purpose; otherwise run it in an isolated environment or inspect/run the scripts manually before use.
Capability Analysis
Type: OpenClaw Skill
Name: content-news-thai
Version: 1.0.0
The skill bundle contains several high-risk behaviors and potential vulnerabilities. The `setup.sh` script performs system-level modifications, including installing packages via `apt-get` with `sudo` and installing fonts system-wide, which may be excessive for a standard skill. Additionally, `gen-news.mjs` is vulnerable to path traversal and arbitrary file writes because it uses unsanitized user input from a JSON string to define the `output` and `bgImage` file paths in `writeFileSync` and `loadImage`. While these actions align with the stated purpose of generating images, the lack of input validation and the requirement for elevated privileges during setup pose a security risk to the host environment.
Capability Assessment
Purpose & Capability
Name/description match the code and instructions: gen-news.mjs renders 1080x1350 images with Thai fonts; setup.sh installs canvas and Thai fonts. There are no unrelated credentials, binaries, or config paths declared.
Instruction Scope
SKILL.md instructs running the provided setup.sh and calling node gen-news.mjs with a JSON param. The runtime will read optional bgImage paths/URLs and write an output file. This is within scope, but the setup step can install system packages, copy fonts system-wide, and requires network access to download fonts and (optionally) fetch remote bgImage URLs — users should be aware of those side-effects before running.
Install Mechanism
No packaged install spec in registry (instruction-only), but setup.sh performs system package installation (apt/brew), runs npm install (canvas), and downloads fonts from GitHub raw URLs. Fonts from Google Fonts on GitHub are expected; npm canvas is a normal dependency but requires native build tools. These are moderate-risk actions because they install system packages and node modules and write files to disk.
Credentials
The skill declares no required env vars or credentials. The code optionally reads OPENCLAW_WORKSPACE to locate fonts if present — this is benign and documented. No unrelated secrets or external service tokens are requested.
Persistence & Privilege
always is false. The setup script may install fonts system-wide (copies to /usr/local/share/fonts) and uses sudo if needed; that modifies system state and may require elevated privileges. The skill does not modify other skills or agent configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install content-news-thai - After installation, invoke the skill by name or use
/content-news-thai - Provide required inputs per the skill's parameter spec and get structured output
