name	legado-book-source-developer
description	Legado (阅读) Android app book source development skill. Use when: creating book sources for novel/manga websites, debugging existing book source rules, querying Legado knowledge (CSS selectors, rule formats, POST requests), analyzing website HTML structure for book source development, or managing book source databases. Covers searchUrl, ruleSearch, ruleToc, ruleContent, ruleBookInfo configuration.

Legado Book Source Developer

Complete toolkit for creating, debugging, and managing Legado book sources. Includes 25+ analysis tools, 134 real book source examples, and a comprehensive knowledge base built from 400K lines of Legado source code.

Quick Start

1. Detect encoding → 2. Fetch real HTML → 3. Query knowledge base → 4. Analyze structure → 5. Create book source

Core principle: All rules MUST be based on real HTML source analysis. No guessing.

Tools

Knowledge Query

Tool	Purpose
search_knowledge(query)	Search knowledge base
get_css_selector_rules()	Complete CSS selector reference (paginated)
get_real_book_source_examples(limit)	134 real book source analysis results
get_book_source_templates(limit)	Proven book source templates
read_file_paginated(path, page)	Read large files with pagination
list_all_knowledge_files()	List all knowledge files

HTML Analysis

Tool	Purpose
smart_fetch_html(url, method, body, headers, charset)	Fetch real HTML with encoding support
smart_web_analyzer(html)	Full page structure analysis
smart_bookinfo_analyzer(html)	Book info page analysis
smart_toc_analyzer(html)	Table of contents analysis
smart_content_analyzer(html)	Content page analysis

Book Source Management

Tool	Purpose
edit_book_source(complete_source="JSON")	Create/edit book source (call ONCE)
validate_book_source.py	Validate book source JSON (in tools/)

Analysis Scripts (in tools/)

Script	Deps	Purpose
analyze_url.py	requests, bs4	⭐通用网站分析（编码+结构+搜索接口）
analyze_url.sh	curl	⭐通用网站分析（无 Python 版）
quick_analyze.py	requests, bs4	快速网站分析（自动存储HTML）
js_param_analyzer.py	requests, bs4	JS参数/端点分析
validate_book_source.py	—	书源JSON验证（零依赖）
upload_book_source.py	requests	书源上传到图床

无 Python 环境？ 见 references/no_python_workflow.md，优先使用宿主系统已配置的 MCP 工具（浏览器/HTTP/代码执行）。

3-Phase Workflow

Phase 1: Information Collection

⚠️ DO NOT create book source in this phase!

Step 1: Query Knowledge Base

search_knowledge("CSS选择器格式 提取类型 @text @html @href @src")
get_real_book_source_examples(limit=5)
get_book_source_templates(limit=3)

Step 2: Detect Encoding (ONCE, at start)

detect_charset(url="http://example.com")

• UTF-8 → omit charset (default)
• GBK/GB2312 → add "charset":"gbk" to all requests

Step 3: Fetch Real HTML

smart_fetch_html(url="http://example.com/search", charset="gbk")
smart_fetch_html(url="http://example.com/search", method="POST",
                 body="keyword={{key}}&t=1", charset="gbk")

Step 4: Analyze Structure

smart_web_analyzer(html="...")
smart_bookinfo_analyzer(html="...")
smart_toc_analyzer(html="...")
smart_content_analyzer(html="...")

Phase 2: Strict Review

1. Write rules based on knowledge base + real HTML analysis
2. Validate CSS selectors, extraction types, regex format
3. Handle special cases (no cover, lazy loading, merged info)

When uncertain → ASK the user. Never guess.

Phase 3: Create Book Source

1. Prepare complete JSON with all required fields
2. Call edit_book_source(complete_source="完整JSON") ONCE
3. Output as standard JSON array (no comments, no code blocks)

Rule String Format

CSS选择器@提取类型##正则表达式##替换内容

Extraction Types:

• @text — text content (includes children)
• @ownText — element text only (excludes children)
• @html — HTML structure
• @textNode — text nodes
• @href — link URL
• @src — image source
• @js — JavaScript processing

Numeric Indices:

• .0 = first, .-1 = last (NOT :first-child / :last-child)

Text Selection:

• text.关键词 (NOT :contains())

Common Patterns

Standard list with cover:

{"bookList": ".book-list .item", "name": ".title@text", "bookUrl": "a@href", "coverUrl": "img@src"}

No cover on search page:

{"coverUrl": ""}

Lazy loading images:

{"coverUrl": "img@data-original||img@src"}

nextContentUrl rule: Chapter number changes → SET it. Page number only → LEAVE EMPTY.

Critical Constraints

Forbidden (confirmed nonexistent in Legado source):

• NO prevContentUrl
• NO :contains() pseudo-class
• NO :first-child / :last-child

Strictly Prohibited:

• Creating book source without fetching real HTML
• Guessing rules without knowledge base query
• Detecting encoding more than once

Required fields: See references/legado_data_structures.md for complete field specs from BookSource.kt, SearchRule.kt, TocRule.kt, ContentRule.kt, BookInfoRule.kt.

Most Used Patterns (from 134 real sources)

CSS Selectors: img(40x), h1(30x), div(13x), content(12x), intro(11x), h3(9x)

Extraction Types: @href(81x), @text(72x), src(60x), @html(33x), @js(25x)
