## What it does

The skill retrieves a video's title, uploader, tags, stats, and part details through API calls. Its `scripts/bili-fetch.sh` script accepts a BVID, an `av` number, a `b23.tv` short link, or a full URL. Stats change over time, so cite them with the accompanying `fetched_at` timestamp.

Use `scripts/bili-danmaku.sh` to retrieve the comments shown over a video; for multi-part videos, it resolves the CID for the selected part. Both scripts work without an account login. Subtitles require a Bilibili session through `scripts/bili-subs.sh`, and the user must be asked before that script runs. Anonymous requests cannot retrieve subtitles, so this is a real constraint when planning a transcript workflow.

```

2. **Manually: put the files in place**
- File: `~/.claude/skills/bilibili-source/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/bilibili-source/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill bilibili-source -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill bilibili-source -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/bilibili-source/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install daymade/claude-code-skills bilibili-source

npx skills add daymade/claude-code-skills --skill bilibili-source -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/daymade/claude-code-skills --path bilibili-source
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/bilibili-source/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill bilibili-source -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/daymade/claude-code-skills/tree/HEAD/bilibili-source/SKILL.md

## When to use it
- fetch video metadata and stats from a BVID
- retrieve a video's tags and uploader details
- collect danmaku text for a selected part
- record the fetch time alongside cited metrics

## Example prompts
- Fetch the latest stats and metadata for this Bilibili video: BV1xxxxxxxxx.
- Get the danmaku text for part two of this video using its b23.tv link.
- Save the video's metrics in a note with their fetch timestamp.

# bilibili-source

Fetch **real, verifiable** data for a Bilibili video so you can cite it instead of guessing. Engagement numbers are the backbone of any honest "why did this do well" analysis, and hand-typed or estimated numbers are the fastest way a knowledge base rots. This skill makes the numbers cheap to fetch — so there is no excuse to invent them.

## Quick start

```bash
scripts/bili-fetch.sh BV1xxxxxxxxx
```

Returns one JSON object with everything from a single `view/detail` API call:

```json
{
  "bvid": "BV1xxxxxxxxx",
  "aid": 1234567890,
  "fetched_at": "2026-06-07T13:54:17Z",
  "url": "https://www.bilibili.com/video/BV1xxxxxxxxx",
  "title": "<video title>",
  "up": { "name": "<UP name>", "mid": 12345678, "fans": 45600 },
  "pubdate": "2026-01-10T00:50:47Z",
  "tname": "<partition, may be empty>",
  "tags": ["<tag>", "<tag>"],
  "videos": 1,
  "duration_s": 372,
  "stat": { "view": 48000, "like": 1200, "coin": 180, "favorite": 950,
            "share": 64, "reply": 210, "danmaku": 130 },
  "pages": [ { "cid": 12345678, "page": 1, "part": "<part title>", "duration": 372 } ]
}
```

`bili-fetch.sh` accepts any form a user might paste — **BVID, `av` number, `b23.tv` short link, or full URL** — and normalizes it. For multi-part videos it returns every part's `cid` in `pages[]` (you need the per-part cid to fetch that part's danmaku or subtitles).

## Scripts

| Script | What it does | Login |
|--------|--------------|-------|
| `scripts/bili-fetch.sh <ref>` | Core: full metadata + live stats (run this first) | No |
| `scripts/bili-danmaku.sh <ref> [P]` | Danmaku (bullet-comment) full text for a part | No |
| `scripts/bili-subs.sh <ref> [browser]` | Subtitle/transcript track | **Yes** |
| `scripts/bili-selftest.sh` | Test anonymous metadata, danmaku and selected API shapes | No |
| `scripts/bili-access.py` | Diagnose identity, entitlement, subtitle shape and per-part media; replay/probe/verify-report | Explicit cookie file only |

The shell fetch scripts **execute** (don't read them as reference). `bili-danmaku.sh` reuses `bili-fetch.sh` to resolve the part's cid, so they must stay siblings in `scripts/`.

**Danmaku** are time-synced comments overlaid on the video — a Bilibili-specific signal of *where and how* viewers reacted, qualitatively richer than a flat reply count:

```bash
scripts/bili-danmaku.sh BV1xxxxxxxxx     # P1; add a part number for multi-part videos
```
