/topic-brief
Turns a window of public news on any subject into a focused thematic briefing — and ships it as a self-contained HTML page built to paste straight into WeChat.把某个主题一段时间内的公开新闻，整理成一份聚焦的主题观察——并产出一个自包含 HTML 页面，能直接贴进公众号。
Type /topic-brief and name a subject — a region, industry, policy issue, institution or theme. One mandatory check-in midway keeps the direction right before any writing happens.输入 /topic-brief，给一个主题——地区、行业、政策、机构或某个题目。中途一次强制确认，动笔前先把方向定准。
Gather first, confirm direction, then write.先抓料，定方向，再动笔。

Collect parameters收集参数
One batched prompt: subject, time window (normalized to two ISO dates), source preference, author byline. If the trigger already named them, skip straight ahead.一次性问清四件事：主题、时间窗（归一成两个 ISO 日期）、信息源偏好、作者署名。触发时已经给全了就直接跳过。

Parallel material gathering并行抓取材料
4–6 search queries, every one time-filtered (after:/before:), across the dimensions that fit the subject type — plus a 1–2 deep-read of the focus report's primary text.4–6 次检索，每次都带时间过滤（after:/before:），按主题类型铺开维度；再深读 1–2 次焦点报告的原文。

Direction check-in方向确认
⚠ Human gate人工把关Stop after gathering. Report the window, the proposed focus report and the 4 sub-sections — every candidate item tagged with its event date — and wait for sign-off. Skipping this causes 5,000-char rewrites.抓完先停。把时间窗、拟定的焦点报告、四个子板块（每条候选都标事件日期）报给你确认，签了字再往下。跳过这一步，方向错了就是 5000 字重写。

Compose the brief成稿
Focus body 1,500–2,500 chars + 4 sub-sections × 3–4 dated items. No fabricated numbers — re-read and ask "where did this come from?" at every figure. In-window discipline enforced.焦点正文 1500–2500 字 + 四个子板块 × 3–4 条带日期的条目。不编数字——写完逐个数字追问“这是哪来的”；每条都卡在时间窗内。

Render & report渲染并交付
render.py produces a self-contained HTML file (quotes auto-fixed) and opens it. Reports back file path, counts and a source-URL list — with a reminder that every number needs human review.render.py 产出一个自包含 HTML（自动修中文引号）并打开。回报文件路径、字数 / 条数和分组源链接——并提醒：每个数字都要人工复核。
