What it does

Bilibili Viral Topic is an agent skill from kangarooking/kangarooking-skills. Find low-follower viral Bilibili videos for account-growth topic selection. Use when the user asks for B站低粉爆款, Bilibili low-fan hits, 起号选题 from B站, niche Bilibili references, or videos ranked by UP主粉丝数, 播放, 点赞, 投币, 收藏, 分享, 评论, 弹幕, and 播放粉丝比.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/category_map.md` and `references/rate_limits.md`).

It works with Bilibili. The repository describes itself as: My custom AI Agent skills.

When your agent uses it

  • The user asks for B站低粉爆款
  • Bilibili low-fan hits
  • Niche Bilibili references
  • Videos ranked by UP主粉丝数

Example prompts

  • “/bilibili-viral-topic”

Requirements

  • Python 3

Workflow steps

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

  1. Convert the user's niche into focused Chinese and product-name keywords.
  2. Search B站 videos through x/web-interface/search/type with order=pubdate and order=click.
  3. Optionally supplement with x/web-interface/ranking/v2 when the user asks for broader platform signals.
  4. Deduplicate by bvid.
  5. Filter to the requested recent window using pubdate.
  6. Enrich each unique mid through x/relation/stat?vmid= and cache follower counts.
  7. Filter
  8. Rank by breakout_score, then play_follower_ratio, then view_count.
  9. Return JSON for automation or Markdown for topic review.

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

    Ships 1 file 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

Bilibili Viral Topic loads about 756 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 282 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~756
With references · SKILL.md plus every file in references/, read only if the agent opens them
~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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 282 words (~756 tokens).

“Use this skill to find B站 videos that significantly outperform the UP主's follower base.”
