::OBJECTIVE{goal:"niche corpus + two skills + 7 ready-to-post drafts"|DONE_WHEN:"niche_corpus.json, topic_skill.md, writing_skill.md, 7 drafts with audience-timezone post times and posting checklist exist; all drafts passed overlap check"}

::FACT{key:algo_cold_start|value:"boost for authors <=50K followers on non-reply posts under 2h old with <200 impressions"|conf:"observed in open-source code, not guaranteed"}
::FACT{key:redfox|value:"data source: signup https://redfox.hk/apis/douyin/P5CHB3BZ (trial credit); MCP https://mcp.redfox.hk/<p>/mcp, p in twitter,xiaohongshu,douyin,youtube,tiktok,instagram,bilibili,gongzhonghao; header REDFOX_API_KEY from env or secret store, never ask in chat"|conf:confirmed}
::FACT{key:length|value:"long posts need X Premium; non-Premium limit 280 weighted chars"|conf:source}
::RULE{S0=>CHEK own X access: RedFox twitter MCP if REDFOX_API_KEY exists, built-in public X reads or X API (search with public_metrics); none=>give user the RedFox signup link and continue with web search; else ask user to paste 20-50 posts; respect rate limits; use the batched question only for niche, language or audience timezone if unclear}
::RULE{S1_VOICE=>handle given=>GET user's original posts; archive file=>READ it; none=>skip voice, use neutral niche voice}
::RULE{S2_CORPUS=>find 10-30 niche accounts via search; GET top originals; rank by (likes+bookmarks+reposts)/impressions; drop replies, retweets, ads, quote filler; atomize to JSON {topic, angle, hook, structure, length, format, metrics, url}; RedFox key=>also pull niche hits from xiaohongshu, douyin, youtube for cross-platform angles; save niche_corpus.json}
::RULE{S3_SKILLS=>CREA topic_skill.md: viral angles, pairing with hot topics, what to skip; CREA writing_skill.md: hook types, structure, rhythm, layout, length, plus user's voice traits if S1 found any; abstract patterns only, no copied lines}
::RULE{S4_DRAFT=>pick this week's hot topics; run topic skill then writing skill; 7 drafts, original top-level posts, on niche; long or 280-char version per Premium status}
::RULE{S5_CHECK=>each draft vs all corpus texts: any shared span >=12 chars or high 5-gram overlap=>rewrite; recheck; log scores}
::RULE{S6_SCHEDULE=>post times when target audience is awake in their timezone; checklist: post original, stay 2h replying to comments, no reply-only days}
::RULE{DELIVER|response:"list files and paths, 7 drafts inline with times, overlap results, data source used; state algorithm notes are observed in open-source code, not guaranteed; state user must post manually"}
::FALLBACK{no_x_access=>RedFox signup link, web search or pasted posts|few_posts=>widen accounts, mark low confidence|no_metrics=>rank by likes and reposts, mark it}
::RUBRIC{corpus:"cleaned, ranked, urls kept"|skills:"patterns only"|drafts:"7, original, on niche"|overlap:"all passed"|honest:"no promises, no posting"}
