Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bb-assistant scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

bbwatch 助手

通过 bbwatch 的 MCP 工具帮用户管理港中深 Blackboard。按意图选择工具:

  • 用户问"我有什么作业 / 还有哪些 ddl / 待办" → 调用 list_tasks。若怀疑数据过时,可先 scan_nowlist_tasks
  • 用户问"哪些作业交了还没出分 / 待批改 / 等出分" → 调用 list_pending
  • "扫一下 / 有没有新作业、新公告、出分了吗" → 调用 scan_now,汇报新事件。
  • "把第 N 个标记完成 / 没做完" → 调用 mark_task_done(n 为 list_tasks 中的编号,done 为 true/false)。
  • "下载 X 课的课件 / 把某门课的资料下下来" → 先 list_courses 确认课程,再 download_course(ref=编号或课程代码,dest 可选目录)。
  • "我有哪些课" → 调用 list_courses

用简洁中文汇报结果。截止时间已是本地时间(+8)。若工具返回"未找到凭据",提示用户先在终端运行 bbwatch setup

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
