Bili Digest

BiliDigest

Use this skill when the user asks to summarize, inspect, or take notes from Bilibili Watch Later, Favorites, or a specific Bilibili video.

This repository is GPL-3.0-or-later and includes attribution notes for BiliTools in NOTICE.

Commands

Prefer the bundled launcher next to this SKILL.md so the skill also works when installed outside the repository:

scripts/bilidigest auth status
scripts/bilidigest auth import-browser edge
scripts/bilidigest auth session-path --json
scripts/bilidigest auth login --json --no-wait
scripts/bilidigest auth poll <qrcode_key> --json
scripts/bilidigest list watch-later --limit 15
scripts/bilidigest list watch-later --limit 600 --no-items
scripts/bilidigest transcript <BV-or-url> --format md
scripts/bilidigest summary <BV-or-url>
scripts/bilidigest batch watch-later --limit 600 --fallback-summary --with-summary

If the launcher cannot find the repository, set BILIDIGEST_HOME to the cloned BiliDigest path. When already inside the BiliDigest project root, these direct commands are equivalent:

python -m tools.bilidigest auth status
python -m tools.bilidigest auth import-browser edge
python -m tools.bilidigest auth session-path --json
python -m tools.bilidigest auth login
python -m tools.bilidigest auth login --json --no-wait
python -m tools.bilidigest auth poll <qrcode_key> --json
python -m tools.bilidigest list watch-later --limit 15
python -m tools.bilidigest list watch-later --limit 600 --no-items
python -m tools.bilidigest list favorites --mid me
python -m tools.bilidigest list favorite --media-id <id> --limit 15
python -m tools.bilidigest transcript <BV-or-url> --format md
python -m tools.bilidigest summary <BV-or-url>
python -m tools.bilidigest batch watch-later --limit 15 --with-summary
python -m tools.bilidigest batch watch-later --limit 600 --fallback-summary --with-summary

Workflow

1. Check login status first.
2. If login is missing and the user uses Microsoft Edge, prefer auth import-browser edge before QR login.
3. For a list request, fetch at most 15 items unless the user explicitly asks for a smaller number.
4. For a video, export Bilibili's existing subtitle first. Do not run ASR unless the subtitle export fails and the user asks for fallback transcription.
5. Read the generated Markdown from output/bilidigest/<date>/ and summarize or organize notes from that text.
6. If Bilibili returns risk-control or login errors, stop and tell the user to re-login or retry later.

Batch Workflow

For large Watch Later runs, prefer the resumable batch command:

scripts/bilidigest batch watch-later --limit 600 --fallback-summary --with-summary

The command stores local cache and state here:

output/bilidigest/cache/watch-later.jsonl
output/bilidigest/cache/watch-later.meta.json
output/bilidigest/snapshots/watch-later.json
output/bilidigest/state/watch-later.json

List commands return the remote total, so agents can use --limit 1 for fast size checks. Rerunning the same batch command resumes from the state file. Completed videos and previously failed videos are skipped. Use --refresh-list when the user explicitly wants a fresh Watch Later list, and --no-resume only when they want to ignore the old state.

For daily automation, refresh the list and process only newly added items:

scripts/bilidigest batch watch-later --limit 600 --refresh-list --only-new --fallback-summary

Do not use --retry-failed in daily automation or large background batches. It is only for manual investigation after a temporary outage; videos without subtitles or AI summaries should remain failed after one attempt.

Chat Login Flow

For chat surfaces such as Hermes Agent, Telegram, or a TUI, do not block forever inside an interactive login command. Run:

python -m tools.bilidigest auth login --json --no-wait

Send the returned login_url or qr_image to the user. Then poll with:

python -m tools.bilidigest auth poll <qrcode_key> --json

Treat logged_in as success, expired as a request to regenerate the QR code, scanned as waiting for phone confirmation, and pending as still waiting for the scan.

Session Storage

The shared macOS session path is:

~/Library/Application Support/BiliDigest/session.json

Do not store session files inside individual Skill directories. Use auth session-path --json to confirm where the CLI is reading from.

Safety

Only process videos the user's own account can already access. Do not expose, print, or copy .user_session.json, cookies, API keys, or .env values into chat.

The CLI intentionally waits about 8-12 seconds between API requests. Do not override the delay for routine daily automation unless the user explicitly asks. The legacy yt-dlp downloader also runs with slow sleeps and one concurrent fragment by default.

For one-off large local batches, a modest override such as BILIDIGEST_DELAY_SECONDS=6 BILIDIGEST_DELAY_JITTER_SECONDS=2 is acceptable when the user explicitly asks to process hundreds of videos. Do not start multiple BiliDigest batch jobs at the same time.
