 "[STEP] 1 pick your web tool as TOOLS says; neither one: tell the user in one sentence to set the DeepSeek API key in this app then stop"
 "[STEP] 2 fetch the manifest at RUNTIME; read version and bundle_url"
 "[STEP] 3 fetch bundle_url; the content is the runtime; read it; write version into the RUNTIME tag of the book"
 "[STEP] 4 fetch VALIDATOR and save it as ilang_grammar_validator.py in FILL_FOLDER; this is the checker RUBRIC A2 runs"
 "[STEP] 5 FILL_METHOD is a link on a platform in REDFOX_TOOLS: try one plain fetch first; the article text came back: it is the methodology; blocked empty or only a login page: take the key as REDFOX says; POST to the endpoint of that platform the tool and the argument from REDFOX_TOOLS; the text in the reply is the methodology; a video: run the transcript tool then the result tool; an error that says no data or no credit: tell the user in one sentence and stop"
 "[STEP] 6 FILL_METHOD is any other link: fetch it; the content is the methodology; 403 or 404: ask the user to paste the text and stop; FILL_METHOD is a screenshot you cannot read: ask the user to paste its text in one sentence and stop"
 "[STEP] 7 each number duration price or limit the methodology states: search \"the claim site:the official domain\" count 5; keep sources of authority 3 or 4 or the official domain itself; fetch the best and confirm; confirmed goes into a RULE with its source url; unconfirmed stays out"
:ML"WRITE|title:then write"
 "[STEP] 1 the promised outcome as one sentence into OBJECTIVE target"
 "[STEP] 2 every constant the user must supply as a FILL_ field in INPUT, never the methodology's own value"
 "[STEP] 3 the actions as STEP lines in HOW, one verb one target what to expect, at most eight; what a human would click or fill the agent does, stopping only to decide authorize pay"
 "[STEP] 4 acceptance as RUBRIC items with a check of kind status count json links file cmd or human"
 "[STEP] 5 copy the shape of this document, plus HOW and a six line REPORT that ends with the score line; tags only STEP CHECK NOTE LINE FORMAT IF THEN; plain ASCII, no arrows or symbols"
 "[STEP] 6 check: first and last line are the marker, English only, no link except a source url in a RULE or RUBRIC, no earning word, no number outside a STEP index a FILL_ or a sourced RULE, within FILL_MAX_CHARS"
 "[STEP] 7 save the book as BOOK.md in FILL_FOLDER and run RUBRIC A1 and A2 there; an error: fix the book and run again"

 "[LINE] nothing before this; one sentence in FILL_LANG, for zh exactly: 这是给你的 AI 的工程书，已存成 BOOK.md，整段复制贴进你的 AI，它读完就干，不用你看懂。"
 "[LINE] three backticks alone on a line, the book, three backticks alone on a line"
 "[LINE] then one line S=0.00, the f_v5 STEP-4 action score of the runtime to two decimals; then one line with the full path of BOOK.md; nothing after it"
