bilibili-cli Skill

A CLI tool for interacting with Bilibili (哔哩哔哩). Use it to fetch video info, search content, browse user profiles, and perform interactions like liking or triple-clicking.

Agent Defaults

When you need machine-readable output:

1. Prefer --yaml first because it is usually more token-efficient than pretty JSON.
2. Use --json only when downstream tooling strictly requires JSON.
3. Keep result sets small with --max, --page, or --offset.
4. Prefer specific commands over broad ones. Example: use bili user-videos 946974 --max 3 --yaml instead of fetching large timelines.
5. When summarizing a video, fetch subtitles first. Subtitles usually contain the video's core content and are the best primary source for summaries.
6. Only fall back to --ai, comments, or audio extraction when subtitles are unavailable or clearly insufficient.

Prerequisites

# Install (requires Python 3.10+)
uv tool install bilibili-cli
# Or: pipx install bilibili-cli

# If you need audio extraction support (requires PyAV)
uv tool install "bilibili-cli[audio]"
# Or: pipx install "bilibili-cli[audio]"

# Upgrade to latest (recommended to avoid API errors)
uv tool upgrade bilibili-cli
# Or: pipx upgrade bilibili-cli

Authentication

Most read commands work without login. Subtitles, favorites/following/watch-later/history, feed, and interactions require login.

bili status                    # Check if logged in (exit 0 = yes, 1 = no)
bili login                     # QR code login (if not authenticated)

Authentication auto-detects local browser cookies (Chrome/Firefox/Edge/Brave). If cookies are found and valid, no manual login needed. Credentials are saved to ~/.bilibili-cli/credential.json.

bili audio BV1ABcsztEcY --segment 60    # 60s per segment

Account

bili status                    # Quick login check
bili status --yaml             # Structured auth status
bili whoami                    # Detailed profile info
bili whoami --yaml              # Profile as YAML
bili whoami --json              # Profile as JSON
bili login                     # QR code login
bili logout                    # Clear credentials

Structured Output

Major query commands support both --yaml and --json for machine-readable output. Prefer YAML for agent use:

bili status --yaml                                # Quick structured auth check
bili video BV1ABcsztEcY --yaml                       # Preferred for AI agents
bili hot --max 5 --yaml                             # Smaller, token-efficient payload
bili user 946974 --json | jq -r '.data.user.name'   # JSON when jq is needed

When stdout is not a TTY, bilibili-cli defaults to YAML automatically. Use OUTPUT=yaml|json|rich|auto to override the default output mode. All machine-readable output uses the envelope documented in SCHEMA.md.

Debugging

bili -v <command>              # Enable verbose/debug logging for any command

Common Patterns for AI Agents

# For video summarization, fetch subtitles first
bili video BV1ABcsztEcY --subtitle

# Only use AI summary as a fallback or secondary signal
bili video BV1ABcsztEcY --ai

# Get comments for sentiment analysis
bili video BV1ABcsztEcY --comments

# Extract audio for speech-to-text (ASR)
# Segments are saved to /tmp/bilibili-cli/{title}/seg_000.wav, seg_001.wav, ...
bili audio BV1ABcsztEcY --segment 25

# Find a user's latest video BV ID with minimal payload
bili user-videos 946974 --max 1 --yaml

# Check if logged in before performing actions
bili status && bili like BV1ABcsztEcY

# Search and inspect the first few results
bili search "topic" --type video --max 3 --yaml

Workflow: Video Content Analysis

# 1. Search for a topic
bili search "AI" --type video --max 5

# 2. Get subtitles first for summarization
bili video BV1xxx --subtitle

# 3. If subtitles are missing or incomplete, try AI summary
bili video BV1xxx --ai

# 4. If there is still not enough content, extract audio for ASR
bili audio BV1xxx --segment 25

# 5. Get comments for audience reaction
bili video BV1xxx --comments

Workflow: UP主 Research

# 1. Look up UP主 profile
bili user "影视飓风"

# 2. Get their recent videos
bili user-videos 946974 --max 10

# 3. Inspect a specific video
bili video BV1xxx --ai --comments

Error Handling

• Commands exit with code 0 on success, non-zero on failure
• Error messages are prefixed with ❌
• Login-required commands show ⚠️ with instruction to run bili login
• Invalid BV IDs show a clear error message

Safety Notes

• Do not ask users to share raw credential/cookie values in chat logs.
• Prefer local browser cookie extraction over manual secret copy/paste.
• If auth fails, ask the user to re-login via bili login.
