Login-free fetch of comprehensive Bilibili (B站) video data in one view/detail call: title, UP follower count, tags, partition, per-part cids, live stats, and full danmaku text. Accepts BVID/av/b23.tv/URL. Ships bili-selftest.sh API-drift health-check and a WBI-signing API reference. All examples synthetic; NO-FABRICATION discipline.

# bili-selftest.sh — Health-check for bilibili-source against the LIVE Bilibili API.
|
|
#
|
|
# Why this exists: this skill wraps a third-party API that changes over time (fields get
|
|
# renamed, endpoints add WBI signing, anti-bot tightens). Without a self-test, drift shows
|
|
# up as a silent wrong answer in production. Run this after Bilibili changes something, or
|
|
# periodically, and API drift surfaces as one clear FAIL row pointing at what broke.
|
|
#
|
|
# It asserts SHAPE (fields exist, right types) and documented INVARIANTS — never exact
|
|
# values, since engagement numbers drift by design.
|
|
#
|
|
# Usage: bili-selftest.sh
|
|
# Deps: curl, jq, python3 (same as the scripts under test).
|
|
# Exit: 0 = all green; 1 = drift detected (see failing rows + references/bilibili_api.md).
|
|
