Skill Directory

<SKILL_DIR> is the directory containing this SKILL.md file. Determine it ONCE at the start and reuse it.

Setup (run FIRST — every time, before any operation)

You MUST complete this setup before running any script. Do NOT skip this step.

sig status bilibili 2>&1

Check the JSON output fields configured and valid:

  • configured: false → run Provider Setup below. Do NOT proceed without completing it.
  • valid: false (but configured: true) → run sig login bilibili, then re-check.
  • valid: true → detect proxy (see below), then execute the user's request.

Provider Setup

  1. Read <SKILL_DIR>/references/provider-config.yaml
  2. Append the provider block to ~/.sig/config.yaml under providers:
  3. Ask the user: "Do you need a proxy to access this site?" — if yes, add networkProxy: <url> under the provider in config.yaml
  4. Run sig login bilibili (with --network-proxy <url> if proxy was specified)
  5. Verify: run sig status bilibili again — must show valid: true before proceeding

Proxy Detection (after provider is valid)

grep -A15 "^\s*bilibili:" ~/.sig/config.yaml | grep networkProxy | awk '{print $2}'

If this outputs a URL, prefix ALL python3 commands with HTTPS_PROXY=<url> HTTP_PROXY=<url>. If using socks5, convert to socks5h for python (e.g. socks5://... → socks5h://...). If empty, no proxy needed.

Running Scripts

All scripts require setup to be completed first (see above).

Read operations — use sig run to inject cookie (enables authenticated features):

sig run bilibili -- bash -c 'python3 <SKILL_DIR>/scripts/bilibili_hot.py --cookie "$SIG_BILIBILI_COOKIE" --limit 10'

Write operations — require sig run (cookie is mandatory):

sig run bilibili -- bash -c 'python3 <SKILL_DIR>/scripts/bilibili_like.py --cookie "$SIG_BILIBILI_COOKIE" --aid 123456'

Env var: SIG_BILIBILI_COOKIE

On auth error (401/403): run sig login bilibili automatically (no user prompt), then retry.

All scripts are in this skill's scripts/ directory. Run via Bash tool.

Safety

Write operations are visible to the user's Bilibili account. Like and favorite are reversible via --undo. Coins cannot be taken back once given.

Always confirm with the user before calling bilibili_coin.py since coins are a limited, non-refundable currency on Bilibili.

Key Concepts

BV IDs — Bilibili videos are identified by BV IDs (e.g. BV1xx411c7mD). Most read scripts accept BV IDs directly.

AIDs — Numeric video IDs used by write operations. Get the aid from video details (bilibili_video.py).

WBI Signing — Search and user profile endpoints require WBI parameter signing. The client handles this automatically.

CSRF Token — Write operations need a bili_jct CSRF token extracted from the session cookie. The client extracts it automatically.

Categories — Ranking supports categories: all (0), anime (1), music (3), dance (129), game (4), tech (188), knowledge (36), life (160), food (211), animal (217), car (223), fashion (155), entertainment (5), movie (181), tv (177).

Pagination — List endpoints accept --page for page number and --limit for page size.

Error Handling

Error Cause Fix
HTTP_412 Request blocked by anti-spam Wait and retry, or use different IP
HTTP_404 Video/user not found Check the ID is correct
AUTH_REQUIRED No cookie for write op Auto-run sig login (no user prompt needed), retry
NO_CSRF No bili_jct in cookie Auto-run sig login (no user prompt needed), retry
API_ERROR Bilibili returned error code Check error message for details
