At a glance

Generate a beautifully designed infographic poster from an article URL or text content.

  • Works in 3 steps: Read the Article → Save Poster Data as JSON → Render to PNG
  • User says article poster
  • SKILL.md covers How It Works, Step 1: Read the Article, Step 2: Save Poster Data as JSON and Step 3: Render to PNG, plus 1 more section
  • Runs Python scripts from its folder; calls python3

What it does

Article Poster is an agent skill from MagicCube/agentara. Generate a beautifully designed infographic poster from an article URL or text content. Trigger when user says "article poster", "文章海报", "infographic", "信息图", "make a poster", "生成海报", "visual summary", or requests to convert an article/blog into a shareable image. NOT for generic poster design.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `render.py`).

It sits in Media & Creative, covering Infographics and Generative and creative coding. The repository describes itself as: Your 24/7 personal assistant powered by Claude Code and OpenAI Codex. Multi-channel messaging, long-term memory, skills, task scheduling, session management, and more — all…

When your agent uses it

  • User says article poster
  • Requests to convert an article/blog into a shareable image

Example prompts

  • “article poster”
  • “infographic”
  • “make a poster”
  • “/article-poster”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Read the Article
  2. Save Poster Data as JSON
  3. Render to PNG

What it can do on your machine

Read from SKILL.md and the folder at commit 5621a96. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Article Poster loads about 1.6k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 482 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 482 words (~1,579 tokens).

“Converts an article (URL or pasted text) into a beautifully designed infographic poster image.”
