Reply to video mentions with clickable timestamps
A developer built an agent skill that reads Bilibili @-mentions, watches the linked video locally, and posts a reply with clickable chapter timestamps, sharing example replies.

What they did
A developer wrote a skill for the DeepSeek Harness agent that drives a logged-in browser. When you @ a bot account under a Bilibili video, the agent finds that video and transcribes it locally. It picks key frames and replies in the right thread with clickable timestamps. An optional script checks for mentions every 30 seconds and messages you on WeChat.
How it went
The author shows real replies in screenshots. They report fixing several traps, such as music videos producing no transcript until a setting was changed (0 segments to 57).
Worth knowing
It posts publicly under your account, so the author recommends a secondary account and a replies-per-hour limit. Bilibili blocks accounts that post too fast.
Try it yourself
Check my [video site] notifications for new mentions of [bot account name] by [my main account name]. For each one, confirm the sender's name matches before acting. Open the video, transcribe it and look at key frames. If it's a tutorial, draft a reply with chapter timestamps in 00:00 format; otherwise draft one short reaction. Show me the draft and wait for my approval before posting it as a reply in that thread.
