What it does

Viral Topic is an agent skill from kangarooking/kangarooking-skills. Route viral topic discovery across platform-specific account-growth skills. Use when the user asks for 起号选题, low-follower viral references, recent viral content, cross-platform topic mining, or does not specify whether to search WeChat, X, Bilibili, or YouTube.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/platforms.md`).

It sits in Productivity & Automation, covering Messaging and chat bots. It works with WeChat, Bilibili and YouTube. The repository describes itself as: My custom AI Agent skills.

When your agent uses it

  • The user asks for 起号选题
  • Low-follower viral references
  • Recent viral content
  • Cross-platform topic mining

Example prompts

  • “/viral-topic”

Workflow steps

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

  1. Normalize the user's niche into 3-8 focused search terms.
  2. Choose platforms from the request. For "全平台" or "各个平台", run all implemented child skills.
  3. Run each platform skill independently with its own defaults
  4. Preserve source URLs, author/account metrics, timing, and evidence labels.
  5. Merge outputs into a cross-platform topic table only after preserving each platform's original evidence.
  6. Label confidence carefully

What it can do on your machine

Read from SKILL.md and the folder at commit 08bbee0. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Viral Topic loads about 873 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 382 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~873
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.2k

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 382 words (~873 tokens).

“Use this skill as the control layer for finding topic references across platforms. It does not fetch data itself; it routes the request to the platform skill whose collection logic matches the platform.”
