What it does

Wechat HTML Cover is an agent skill from 843645440/wechat-skill. 使用受约束 JSON、固定 HTML/CSS 和 Chrome/Chromium 确定性生成微信公众号封面 PNG。用于完整公众号流水线必须提供 thumbmediaid,或需要准确中文标题、独立封面视觉且不调用图片模型的 1410×600 封面时;不生成正文图片。

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `references/apparmor-headless-shell.md` and `references/cjk-title-legibility.md`).

It sits in Productivity & Automation, covering Messaging and chat bots. It works with WeChat. The repository describes itself as: 微信公众号内容 Skill 工具包:热点发现、科技写作、去 AI 味、配图、排版、多账号草稿与工作流编排。

When your agent uses it

  • Tasks that involve Messaging and chat bots

Example prompts

  • “/wechat-html-cover”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. 自动选择一套模板;正文主题标识只保留在规格中用于追踪,不控制封面配色。同一任务恢复时沿用原模板。
  2. 让固定脚本从最终 article.md 读取标题和合适的正文短句,自动拆分为两行或三行,并生成合法重点词。不要让 Agent 手写或猜测 title_lines、highlights

What it can do on your machine

Read from SKILL.md and the folder at commit 8ae1abe. 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 2 files in scripts/ (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

Wechat HTML Cover loads about 678 tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 38 tokens; SKILL.md has 115 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~678
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 115 words (~678 tokens).

“根据最终标题生成一张 1410×600 PNG。提供 signal-editorial、night-signal 与 redaction-poster 三套独立于正文主题的可切换模板;当前不在 Skill 内绑定账号。该 Skill 只负责封面,不分析或生成正文配图。”
