Bilibili AI Subtitle Downloader v2.0

Download AI-generated subtitles from Bilibili videos quickly.

What This Skill Does

This skill downloads AI-generated subtitles (自动生成的字幕) from Bilibili videos. These are subtitles automatically created by Bilibili's AI system, not manually uploaded by creators.

Key improvements from v1.x:

✅ Customizable language priority (e.g., prefer English over Chinese)
✅ Better filename format: Title_Author_Date_Duration_BVid.txt
✅ Three-part document structure (Info, Summary, Full Text)
✅ Improved UTF-8 filename handling
✅ Better WSL Chromium/Windows Edge Cookie support

Supported AI Languages

Bilibili uses ai- prefix for AI-generated subtitles:

Code	Language	语言
`ai-zh`	Chinese	中文
`ai-en`	English	英文
`ai-ja`	Japanese	日文
`ai-es`	Spanish	西班牙文
`ai-ar`	Arabic	阿拉伯文
`ai-pt`	Portuguese	葡萄牙文
`ai-ko`	Korean	韩文
`ai-de`	German	德文
`ai-fr`	French	法文

Usage

./scripts/bilibili_ai_subtitle.sh "https://www.bilibili.com/video/BVxxxxx/"

Specify Language Priority

# Prefer English, fallback to Chinese
./scripts/bilibili_ai_subtitle.sh -l en,zh "BVxxxxx"

# Prefer Japanese
./scripts/bilibili_ai_subtitle.sh --lang ja "BVxxxxx"

# Multiple languages in order of preference
./scripts/bilibili_ai_subtitle.sh -l en,zh,ja,es "BVxxxxx"

Setup

Browser Cookie (Recommended)

For accessing member-only videos, log in to Bilibili in:

WSL Chromium (preferred): chromium-browser &
Windows Edge: Log in normally

The script will automatically detect and use available cookies.

Requirements

yt-dlp installed
Optional: Browser with Bilibili login (for member-only videos)

Notes

AI subtitles are generated automatically by Bilibili's system
Accuracy varies (typically 85-95% for clear speech)
Not all videos have AI subtitles available
Some videos may require membership to access AI subtitles

Comparison with bilibili-transcript

Feature	bilibili-ai-subtitle	bilibili-transcript
Purpose	Download AI subtitles only	Full transcription workflow
Speed	⚡ Fast (instant download)	Varies (subtitles → Whisper)
Subtitle sources	AI only	CC → AI → Whisper
Use case	Quick subtitle grab	Complete transcription
Dependencies	yt-dlp only	yt-dlp + optional Whisper

Recommendation: Use bilibili-ai-subtitle for quick AI subtitle download, use bilibili-transcript when you need complete transcription (including voice transcription for videos without subtitles).

安全使用建议

This skill appears coherent for its stated purpose. Before installing/running: 1) Ensure yt-dlp and python3 are installed and up-to-date. 2) Review the script yourself (it is short and readable). 3) Be aware it will try to read local browser cookie stores (WSL Chromium path or Windows Edge user data under /mnt/c/Users) to access member-only videos — if you don't want that, run the script without cookies or remove the cookie-detection block. 4) Provide an explicit output directory when invoking to avoid the hardcoded /home/administrator path. 5) Run in a sandbox or test environment if you are unsure about giving the script access to browser profile directories.

功能分析

Type: OpenClaw Skill Name: bilibili-ai-subtitle Version: 2.0.0 The script `scripts/bilibili_ai_subtitle.sh` automatically attempts to locate and access browser cookie databases from the host system, specifically targeting WSL Chromium and Windows Edge profiles (via `/mnt/c/Users/`). While this is documented as a feature to allow `yt-dlp` to access member-only content, the automated scanning of host user directories and browser data represents a significant privacy risk. There is no evidence of intentional data exfiltration or malicious logic, but the capability to access sensitive host-level credentials warrants a suspicious classification.

能力评估

✓ Purpose & Capability

The name/description (download Bilibili AI subtitles) align with the provided script and SKILL.md. The script uses yt-dlp to list and fetch AI subtitles, parses metadata, and writes a formatted TXT — all directly related to the stated purpose.

ℹ Instruction Scope

Runtime instructions and the script stay within subtitle-download scope. The script enumerates local browser cookie stores (WSL Chromium path and Windows Edge user data under /mnt/c/Users) to supply yt-dlp with cookies for member-only videos — this is relevant to the feature but does access local browser profile paths. No other files, external endpoints, or unrelated system data are accessed or transmitted.

✓ Install Mechanism

There is no install step (instruction-only + shell script). No remote downloads or archive extraction are performed by the skill itself. The only declared dependency in SKILL.md is yt-dlp (the script also uses python3, coreutils like sed/grep/find/wc/date which are normal).

ℹ Credentials

The skill requests no environment variables or credentials. It does, however, attempt to read local browser cookie stores and enumerates /mnt/c/Users to locate a Windows Edge profile for cookie extraction — behavior that is explainable for accessing member-only videos but is sensitive because it uses authenticated browser cookies. Also the default output directory is a hardcoded path (/home/administrator/.openclaw/workspace/...) if none is provided, which may be surprising; supplying an explicit output directory is advisable.

✓ Persistence & Privilege

The skill does not request permanent presence (always: false) and does not modify other skills or global agent config. It runs only when invoked.
