sync(v.download(output='./video.mp4'))
"

Download Options

Video Quality

Specify quality with qn parameter (127=8K, 126=杜比, 125=1080P+, etc.)
Default selects best available quality

Covers and Thumbnails

Get cover URL: v.get_cover()
Download cover: sync(v.download_cover(output='./cover.jpg'))

Common Tasks

Download Single Video

from bilibili_api import video, sync
v = video.Video(bvid='BV1xx411c7m2')
sync(v.download(output='./video.mp4'))

Download with Specific Quality

from bilibili_api import video, sync
v = video.Video(bvid='BV1xx411c7m2')
info = v.get_download_url(qn=127)  # 8K quality

Download Entire Playlist

from bilibili_api import video, sync
from bilibili_api import playlist

pl = playlist.Playlist(playlist_id='123456')
for v in sync(pl.get_videos()):
    sync(v.download(output=f'./playlist/{v["title"]}.mp4'))

Download Audio Only

from bilibili_api import video, sync
v = video.Video(bvid='BV1xx411c7m2')
sync(v.download_audio(output='./audio.mp3'))

安全使用建议

This skill appears to do what it says: download Bilibili videos, audio, subtitles, and covers using the bilibili_api client. Before installing or running: (1) Review where you store authentication cookies — do not keep SESSDATA in a repo or shared config; prefer setting BILIBILI_SESSDATA as an environment variable at runtime. (2) Verify you trust the bilibili-api-python package you will pip install (check the package source and maintainers). (3) Expect the scripts to write files to the local filesystem (output directories in config); ensure the output path is acceptable. (4) The bundle includes runnable scripts — you may want to inspect or run them in a sandbox first if you have concerns. If you need higher assurance, ask the publisher for clarification about how authentication cookies are consumed (environment vs config file) and why the registry lists no required env vars while the README references SESSDATA.

功能分析

Type: OpenClaw Skill Name: bilibili-downloader Version: 1.0.0 The skill bundle is designed for downloading Bilibili content, which aligns with its stated purpose. However, the Python scripts (`scripts/*.py`) accept user-controlled `output_path` arguments directly from `sys.argv` and use them in `os.makedirs` and `os.path.join` without robust sanitization or validation. While filenames derived from video titles are partially sanitized (truncation, replacing '/'), the `output_path` itself could be manipulated by a malicious user or an exploited agent to write files to arbitrary locations on the filesystem (e.g., `/etc/passwd`), leading to a local file write vulnerability. This is a high-risk capability without clear malicious intent, classifying it as suspicious rather than benign. There is no evidence of data exfiltration, backdoors, or prompt injection against the agent.

能力评估

✓ Purpose & Capability

Name/description match the included scripts and instructions: all code uses the bilibili_api library to fetch video/audio/subtitles/covers and write them to disk. No unrelated services, binaries, or credentials are requested.

ℹ Instruction Scope

SKILL.md and scripts only describe running the bilibili_api client and writing downloaded assets to local disk and config files. They instruct (reasonably) how to provide a SESSDATA cookie for premium content. Note: the provided config file contains a cookies.SESSDATA placeholder — the scripts do not directly read that field, but the bilibili_api library may read environment variables or cookies; this is plausible but not explicitly wired in the included scripts.

ℹ Install Mechanism

Registry shows no install spec (instruction-only), which is low risk. However, the package includes multiple runnable Python scripts in the bundle (not purely prose), so the 'instruction-only' label is slightly misleading but not dangerous. The SKILL.md recommends installing bilibili-api-python via pip and requires ffmpeg locally — both expected for this functionality.

ℹ Credentials

No required environment variables are declared by the registry, which is proportional. SKILL.md advises exporting BILIBILI_SESSDATA for authenticated/premium downloads; that's reasonable. Caution: the included config JSON contains a plaintext cookies.SESSDATA placeholder. Storing session cookies in config files (or committing them) is a security/privacy risk — the skill itself does not demand broad unrelated credentials.

✓ Persistence & Privilege

Skill does not request persistent/always-on presence and uses no special agent-level privileges. It performs local file I/O for downloads and config, which is appropriate for its purpose.
