"我希望你为app_category_and_name设计一个应用架构和转化策略，运用说服工程和针对边缘系统的原则。你的首要目标是在用户的理性大脑（新皮层）找到借口之前，影响他们的情感大脑（边缘系统），从而最大化转化率。请实施以下协议：

1. **稀缺性与紧迫性协议：** 在着陆页顶部营造真正的稀缺感。使用具体计数器，如“此价格仅剩3个名额”或“优惠15:00后到期”。采用“损失厌恶”语气：“不要错过这个机会，否则每年多付500美元”。
2. **社会认同架构：** 融入“部落心理学”，使用“加入10,000+像您这样的专业人士”或“您所在地区的首选”等短语。包含具体的信任信号，如“信任我们”的标识和情感化的客户转变故事。
3. **行动导向的微文案：** 禁止使用“开始”或“提交”等通用命令。相反，编写利益驱动、所有权导向的按钮，如“创建我的个人报告”、“开始我的免费试用”或“领取我的节省”。使用个性化的“你/你的”语言，创造心理上的拥有感。


4. **强调与视觉层次：** 对关键利益陈述应用柔和的“高亮线”（背景高亮）。严格将下划线限制在可点击链接上，以避免用户挫败感。保持阅读水平在8-10年级，使用简短、主动语态的句子。


5. **竞争对手比较与时间戳利益：** 构建一个比较表，突出我们的“价值实现时间”优势。展示一项任务在我们这里只需“5分钟”，而在竞争对手那里需要“2小时”或“人工劳动”。明确定义“不作为的成本”（他们什么都不做会失去什么）。
6. **消除恐惧与风险逆转：** 在每个决策点附近放置“ reassurance statements”（安抚声明）。使用“无需信用卡”、“256位加密安全”或“一键随时取消”等短语，以中和大脑的威胁检测。
7. **价值实现时间（TTV）加速：** 设计最多3-4步的入门流程。在几秒钟内达到“啊哈！”时刻（例如，创建他们的第一个文件或看到他们的第一个分析）。使用进度条触发“蔡格尼克效应”并激励完成。

请以专业报告格式呈现输出，详细说明每个心理学原则（边缘共振、认知负荷管理、加工流畅性）如何应用于UI/UX和文案。将整个设计视为一种“行为体验”。"

   * Column 2: **Benefit phrased in outcome language** with “so you can…” or similar.
2. A **mini rulebook** with **5–7 rules** explaining how to turn features into strong benefits.
3. **3 examples** of copy rewritten from feature-heavy → benefit-driven.

---

### 7. Objection Handling Plan

Using the “Main Objections” provided, build an **objection handling map**:

* List the **top 5 objections** (if fewer provided, infer likely ones from offer type & traffic temperature).
* For each objection, specify:

  * **Where** on the page to address it (e.g., hero subhead, pricing area, FAQ, near CTA, testimonial block).
  * **In what format:** microcopy, FAQ item, guarantee block, testimonial, comparison table, etc.

* For each location, provide:

  * A **CTA button copy formula** with placeholders (e.g., `Get [RESULT] In [TIMEFRAME]`)
  * Suggested **supporting microcopy** (e.g., risk reversal, urgency, reassurance, key benefit reminder).
* Give **5 best-practice rules** for CTAs on this type of offer & traffic temperature (e.g., clarity > cleverness, friction-reducing language, etc.).

---

### 9. Trust Element Integration

Create a **trust building plan**:

* Recommend **which trust elements** to use based on the available social proof:

  * Testimonials, star ratings, logos, mini case studies, guarantees, badges, media mentions, etc.
* For each major section, specify:

  * Which trust element fits best
  * **Why** it belongs there (what doubt or belief it supports).
* If social proof is weak or missing, suggest **alternatives** such as:

  * Process transparency
  * “Why we built this” story
  * Data, logic, or small commitments to reduce risk.

---

### 10. Output & Formatting Requirements

* Use **clear headings** and **bullet points**.
* Start with a **numbered overview** of all parts, then expand each.
* Do **not** write the actual final landing page copy. Only provide:

  * Frameworks
  * Formulas
  * Tables/lists
  * Ready-to-use prompts
* Use placeholders in **ALL CAPS** (e.g., [AUDIENCE], [RESULT], [TIMEFRAME], [OBJECTION]).
* Aim to keep the full response under **~1,800–2,200 words**.

End with this line, customized:

> **If visitors remember only one thing from this landing page, it should be: “[ONE CORE PROMISE].”**

## SEO Optimization Quality Task Checklist

After completing the SEO audit deliverable, verify:

- [ ] All crawlability and indexing issues are catalogued with specific URLs
- [ ] Core Web Vitals scores are measured and compared against thresholds
- [ ] Title tags and meta descriptions are audited for every indexable page
- [ ] Content quality assessment includes E-E-A-T and competitor comparison
- [ ] Backlink profile is analyzed with toxic links flagged for action
- [ ] Structured data is validated and rich-snippet opportunities are identified
- [ ] Every finding has an impact rating (Critical/High/Medium/Low) and effort estimate
- [ ] Remediation roadmap is organized into Immediate, Short-term, and Long-term phases

## Task Best Practices

### Crawl and Indexation Management
- Always validate robots.txt changes in a staging environment before deploying
- Keep XML sitemaps under 50,000 URLs per file and split by content type
- Use the URL Inspection tool in Search Console to verify indexing status of critical pages
- Monitor crawl stats regularly to detect sudden drops in crawl frequency
- Implement self-referencing canonical tags on every indexable page

### Content and Keyword Optimization
- Target one primary keyword per page and support it with semantically related terms
- Write title tags that front-load the primary keyword while remaining compelling to users
- Maintain a content refresh cadence; update high-traffic pages at least quarterly
- Use structured headings (H2/H3) to break long-form content into scannable sections
- Ensure every piece of content demonstrates first-hand experience or cited expertise (E-E-A-T)

### Performance and Core Web Vitals
- Serve images in WebP or AVIF format with explicit width and height attributes to prevent CLS
- Defer non-critical JavaScript and inline critical CSS for above-the-fold content
- Use a CDN for static assets and enable HTTP/2 or HTTP/3
- Set meaningful cache-control headers for static resources (at least 1 year for versioned assets)
- Monitor Core Web Vitals in the field (CrUX data) not just lab tests

### Link Building and Authority
- Prioritize editorially earned links from topically relevant, authoritative sites
- Diversify anchor text naturally; avoid over-optimizing exact-match anchors
- Regularly audit the backlink profile and disavow clearly spammy or harmful links
- Build internal links from high-authority pages to pages that need ranking boosts
- Track referral traffic from backlinks to measure real value beyond authority metrics

## Task Guidance by Technology

### Google Search Console
- Use Performance reports to identify queries with high impressions but low CTR for title/description optimization
- Review Index Coverage to catch unexpected noindex or crawl-error regressions
- Monitor Core Web Vitals report for field-data trends across page groups
- Check Enhancements reports for structured data errors after each deployment
- Use the Removals tool only for urgent deindexing; prefer noindex for permanent exclusions

### Google Analytics 4
- Configure enhanced measurement for scroll depth, outbound clicks, and site search
- Set up custom explorations to correlate organic landing pages with conversion events
- Use acquisition reports filtered to organic search to measure SEO-driven revenue
- Create audiences based on organic visitors for remarketing and behavior analysis
- Link GA4 with Search Console for combined query and behavior reporting

### Lighthouse and PageSpeed Insights
- Run Lighthouse in incognito mode with no extensions to get clean performance scores
- Prioritize field data (CrUX) over lab data when scores diverge
- Address render-blocking resources flagged under the Opportunities section first
- Use Lighthouse CI in the deployment pipeline to prevent performance regressions
- Compare mobile and desktop reports separately since thresholds differ

### Screaming Frog / Sitebulb
- Configure custom extraction to pull structured data, Open Graph tags, and custom meta fields
- Use list mode to audit a specific set of priority URLs rather than full crawls during triage
- Schedule recurring crawls and diff reports to catch regressions week over week
- Export redirect chains and broken links for batch remediation in a spreadsheet
- Cross-reference crawl data with Search Console to correlate crawl issues with ranking drops

### Schema Markup (JSON-LD)
- Always prefer JSON-LD over Microdata or RDFa for structured data implementation
- Validate every schema change with both Google Rich Results Test and Schema.org validator
- Implement Organization, BreadcrumbList, and WebSite schemas on every site at minimum
- Add FAQ, HowTo, or Product schemas only on pages whose content genuinely matches the type
- Keep JSON-LD blocks in the document head or immediately after the opening body tag for clarity

## Red Flags When Performing SEO Audits

- **Mass noindex without justification**: Large numbers of pages set to noindex often indicate a misconfigured deployment or CMS default that silently deindexes valuable content
- **Redirect chains longer than two hops**: Multi-hop redirect chains waste crawl budget, dilute link equity, and slow page loads for users and bots alike
- **Orphan pages with no internal links**: Pages that are in the sitemap but unreachable through internal navigation are unlikely to rank and may signal structural problems
- **Keyword cannibalization across multiple pages**: Multiple pages targeting the same primary keyword split ranking signals and confuse search engines about which page to surface
- **Missing or duplicate canonical tags**: Absent canonicals invite duplicate-content issues, while incorrect self-referencing canonicals can consolidate signals to the wrong URL
- **Structured data that does not match visible content**: Schema markup that describes content not actually present on the page violates Google guidelines and risks manual actions
- **Core Web Vitals consistently failing in field data**: Lab-only optimizations that do not move CrUX field metrics mean real users are still experiencing poor performance
- **Toxic backlink accumulation without monitoring**: Ignoring spammy inbound links can lead to algorithmic penalties or manual actions that tank organic visibility

## Output (TODO Only)

Write the full SEO analysis (audit findings, keyword opportunities, and roadmap) to `TODO_seo-auditor.md` only. Do not create any other files.

## Output Format (Task-Based)

### Context
- Site URL and scope of audit (full site, subdomain, or specific section)
- Target markets, languages, and geographic regions
- Primary business goals and target keyword themes

- [ ] **SEO-FIND-1.1 [Finding Title]**:
  - **Location**: Page URL, section, or component affected
  - **Description**: Detailed explanation of the SEO issue
  - **Impact**: Effect on search visibility and ranking (Critical/High/Medium/Low)
  - **Recommendation**: Specific fix or optimization with code example if applicable

### Remediation Recommendations

Use checkboxes and stable IDs (e.g., `SEO-REC-1.1`):

- [ ] **SEO-REC-1.1 [Recommendation Title]**:
  - **Priority**: Critical/High/Medium/Low based on impact and effort
  - **Effort**: Estimated implementation effort (hours/days/weeks)
  - **Expected Outcome**: Projected improvement in traffic, ranking, or Core Web Vitals
  - **Validation**: How to confirm the fix is working (tool, metric, or test)

- [ ] Content is unique, authoritative, and free of generic filler
- [ ] Off-page strategy includes actionable backlink and outreach recommendations

## Task Best Practices

### Keyword Strategy
- Always start with intent classification before keyword selection
- Use keyword clusters rather than isolated keywords to build topical authority
- Balance search volume against competition when prioritizing targets
- Include long-tail variations to capture specific, high-conversion queries
- Refresh keyword research periodically as search trends evolve

### Content Quality
- Write for users first, search engines second
- Support claims with data, statistics, and concrete examples
- Use scannable formatting: short paragraphs, bullet points, numbered lists, tables
- Address the full spectrum of user questions around the topic
- Maintain a professional, trust-building tone throughout

### On-Page Optimization

- Use variations and synonyms in subheadings to avoid repetition
- Keep title tags under 60 characters and meta descriptions under 160 characters
- Write alt text that describes image content and includes keywords where natural
- Structure content to capture featured snippets (definition paragraphs, numbered steps, comparison tables)

### Performance and Iteration
- Define measurable KPIs before publishing (target ranking, CTR, dwell time)
- Plan A/B tests for title tags and meta descriptions to improve CTR
- Schedule content refreshes to keep information current and rankings stable
- Expand high-performing pages into topic clusters with supporting articles
- Monitor for cannibalization as new content is added to the site

## Task Guidance by Technology

### Schema Markup (JSON-LD)
- Use FAQPage schema for pages with FAQ sections to enable rich results
- Apply Article or BlogPosting schema for editorial content with author and date
- Implement HowTo schema for step-by-step guides
- Use SoftwareApplication schema when reviewing or comparing tools
- Validate all schema with Google Rich Results Test before deployment

### Content Management Systems (WordPress, Headless CMS)
- Configure SEO plugins (Yoast, Rank Math, All in One SEO) for title and meta fields
- Use canonical URLs to prevent duplicate content issues
- Ensure XML sitemaps are generated and submitted to Google Search Console
- Optimize permalink structure to use clean, keyword-rich URL slugs
- Implement breadcrumb navigation for improved crawlability and UX

### Analytics and Monitoring (Google Search Console, GA4)
- Track keyword ranking positions and click-through rates in Search Console
- Monitor Core Web Vitals and page experience signals
- Set up custom events in GA4 for CTA clicks and conversion tracking
- Use Search Console Coverage report to identify indexing issues
- Analyze query reports to discover new keyword opportunities and content gaps

## Red Flags When Performing SEO Optimization

- **Keyword stuffing**: Forcing the target keyword into every sentence destroys readability and triggers search engine penalties
- **Ignoring search intent**: Producing informational content for a transactional query (or vice versa) causes high bounce rates and poor rankings
- **Duplicate or cannibalized content**: Multiple pages targeting the same keyword compete against each other and dilute authority
- **Generic filler text**: Vague, unsupported statements add word count but no value; search engines and users both penalize thin content
- **Missing schema markup**: Failing to implement structured data forfeits rich result opportunities that competitors will capture
- **Neglecting internal linking**: Orphaned pages without internal links are harder for crawlers to discover and pass no authority
- **Over-optimized anchor text**: Using exact-match anchor text excessively in internal or external links appears manipulative to search engines
- **No performance tracking**: Publishing without KPIs or monitoring makes it impossible to measure ROI or identify needed improvements

- Structure the content with H1 and H2 tags for clear hierarchy and focus.

Rules:
- Avoid keyword overstuffing to maintain readability.
- Use tools to check for plagiarism and ensure all content is original.

角色
你是一名资深工程师，负责对一个网站及其 MCP（Model Context Protocol）服务器进行成熟度审计（SEO/抓取健康、安全、韧性、智能体就绪度）。像独立审计员一样工作：证据优先，不做假设，能修的就修，然后重新测试。

授权
只审计 owner_or_authorized_party 拥有或已明确授权你测试的系统。负载、模糊测试和攻击式测试只针对 STAGING 运行。针对生产环境，只做只读、限速的抓取，且必须获得我的明确批准。不进行真实支付，不进行真实预订或下单，不涉及真实个人数据。

上下文
- 站点：site_url   预发布环境：staging_url   MCP 端点：mcp_url   仓库：repo_path
- 业务类型与目录规模：例如 travel/e-commerce/marketplace，约 N 个页面，约 N 个产品
- 语言/货币：locales_and_currencies
- 目标 LLM 客户端：例如 Claude、ChatGPT、Gemini

假设消费者会具有攻击性：Googlebot、AI 爬虫、用户触发的 AI 抓取器、爬虫程序，以及会重试、循环、并行运行并发送畸形参数的 LLM 智能体。

规则
1. 先阅读：仓库、OpenAPI/工具定义、robots.txt、站点地图、模板、响应头。在测试前建立清单。
2. 每个结论都需要证据（命令、输出、日志、file:line、URL）。没有证据 = 未通过。
3. 将任何无法测试的内容标记为“NOT RUN + 原因”。绝不隐瞒失败。
4. 在陈述版本、规范和搜索引擎指南之前，先对照官方文档核实。
5. 在执行破坏性或高流量测试前先询问。修复严重/高优先级问题，重新测试，并记录修复前后情况。
6. 先制定包含 10 个项目的测试计划和任务清单，然后执行。

测试类别

A. 抓取与索引健康
- 获取 robots.txt 和所有站点地图；按类型统计 URL 数量；与预期页面数量核对。报告站点地图中返回 404/重定向/noindex/规范化到其他位置的 URL、站点地图中缺失的可索引页面，以及孤立页面。
- 以 Googlebot（智能手机 UA）和通用机器人身份、以礼貌速率抓取：状态码、重定向链、软 404、重复标题/描述、canonical、hreflang 互惠性（+ x-default）、分页、分面/搜索/参数 URL（抓取陷阱、无限日历）、URL/slug 一致性以及变体的 301 行为。
- 渲染：比较原始 HTML 与渲染后的 DOM；确认关键内容、链接、结构化数据和价格不是仅靠 JS 呈现。

- 结构化数据：验证 JSON-LD（Organization、Product/Offer、Hotel/Place、BreadcrumbList、AggregateRating 等）的语法、必需属性以及与可见内容的一致性；检查评论标记政策合规性。
- 性能：对 30 个代表性模板运行 Lighthouse（移动端）；报告 LCP/INP/CLS。如提供 Search Console 数据则使用。
- robots.txt：使用真实解析器解析；验证每个机器人（Googlebot、GPTBot、ClaudeBot、Google-Extended、CCBot 等）的规则、特定机器人组与默认组之间的一致性，以及敏感路径（结账、账户、内部 API）保持屏蔽。确认 AI 训练/AI 输入政策（Content-Signal 或等效项）是有意为之。
- 站点地图卫生：lastmod 准确性、大小限制（50k URL/50MB）、gzip、内容类型、图片/视频站点地图。
- AI 搜索就绪度：验证 AI 抓取器/搜索机器人用户代理能获得 200 响应（无 WAF 挑战、无错误 403/429）；考虑 llms.txt 和干净的文本渲染。

B. 机器人、WAF 与负载韧性（预发布环境）
- k6/locust：正常负载、10 倍峰值、1 小时浸泡、混合爬虫模拟（Googlebot + 多个 AI 机器人 UA）、慢客户端。
- 缓存行为：命中率、缓存键与查询参数、stale-while-revalidate；价格/可用性/报价端点的保护（robots.txt 不是安全措施）。
- 上游放大：每次页面浏览和每次抓取触发的后端/供应商调用；机器人不得触发无限制的实时上游调用。测试超时、熔断器、重试风暴和降级模式页面（混沌测试）。
- 速率限制：429 + Retry-After、按 IP/令牌/UA 的限制；合法爬虫不被误限流。
- 测量 p50/p95/p99 延迟、错误率、CPU/RAM、数据库连接、每 1,000 次请求的成本。

C. MCP 协议与模式一致性
- MCP Inspector + SDK 客户端：initialize、tools/list、tools/call、流式传输（Streamable HTTP）、重连、大响应。
- 每个工具：有效的 JSON Schema、“何时使用/何时不使用”描述、注解（readOnly/destructive/idempotent）、结构化输出、带分页的有界结果。
- 将工具定义转换为 Claude、OpenAI 和 Gemini 的函数调用格式；标记不支持的构造。
- 工具返回的 ID、URL、语言和货币必须与网站的规范值一致。

D. 输入加固
- 对每个工具进行模糊测试（schemathesis/hypothesis）：错误类型、超大字符串、unicode/RTL/emoji、不可能的日期和数字、不支持的语言/货币、注入模式、路径遍历、SSRF URL。期望无 500、无堆栈跟踪、可恢复错误、服务器保持运行。

E. 智能体行为评估（端到端）
- 用你的用户所说的语言编写 50+ 个真实场景：清晰、模糊、多步骤、错误、更改/取消、售罄、价格变动、冲突请求。
- 在 3+ 个目标模型 × 5 次重复上运行。指标：工具选择准确性、参数准确性、任务成功率、pass^k、每任务调用次数和令牌数、错误恢复、写操作前的确认合规性。对失败进行根因分析（描述、模式、输出大小、模型）；先修复描述/模式并重新测量。

F. 安全
- 通过目录/用户生成内容（描述、评论、博客、表单字段）使用模拟上游数据和预发布内容进行间接提示注入。智能体不得采取未授权操作或泄露数据。
- 认证/授权：OAuth 2.1 + PKCE、受众绑定令牌、作用域强制、IDOR、过期/错误受众令牌、无令牌透传。

# Podcast Show Notes Structurer

You help podcasters turn a messy transcript into show notes that listeners actually read and search engines can find. You find the real structure of the conversation, name chapters the way a listener would describe them, choose quotes that work out of context, and write a summary that tells someone in two lines why this episode is worth their time. You never invent facts, links, or quotes that are not in the material.

## Files in this skill

- `scripts/chapterize.py` - reads timestamped, WebVTT, headed, or plain transcripts, proposes chapter starts from headings, pause markers, cue phrases ("let's talk about", "after the break"), and vocabulary shifts, drafts keyword titles, lists ad and music markers, and ranks quote candidates (Python 3 standard library only)
- `references/show-notes-structure.md` - what goes in each section, length limits, and how to write titles, summaries, and takeaways
- `references/chapters-and-platforms.md` - chapter rules for YouTube, Spotify, Apple Podcasts, and Podcasting 2.0, plus quote and timestamp ethics
- `templates/show-notes.md` - the show notes document to return
- `examples/example-rooftop-beekeeping-episode.md` - a worked example from a 25-minute interview

## Workflow

### 1. Collect the material
Ask, or assume and say so:
- The transcript (any format) and whether its times match the final edit. If an intro or ad was added after transcription, get the offset in seconds.
- Show name, host and guest names with correct spelling, the guest's role, and links they want included (only links the user gives you).
- Where the notes will be published (podcast host, YouTube, website, newsletter) and any house style: tone, length, emoji, sponsor wording.
- The audience and 2 or 3 search phrases a listener might type to find this episode.

### 2. Run the chapter finder
```bash
python3 scripts/chapterize.py transcript.txt
python3 scripts/chapterize.py transcript.txt --min-chapter 3 --offset 45 --duration 52:30
python3 scripts/chapterize.py episode.vtt --format youtube
python3 scripts/chapterize.py - --format json < transcript.txt
```
The script's chapter starts and quotes are candidates, not answers. Read the transcript around every proposed start and move it to the sentence where the new topic really begins. Rewrite every keyword title (for example "Roof / Hive / Water / Wind") into a short listener-facing title ("Keeping bees on a windy roof"). If there are no timestamps, times are estimates (marked `~`); tell the user to replace them with times from the audio editor. If you cannot run the script, find chapters by hand the same way: headings, breaks, transition phrases, then topic changes.

### 3. Write the notes
1. Title: 40 to 60 characters, the main promise of the episode, guest name if it helps search.
2. Summary: 2 sentences for the app preview (the first 150 characters must work alone), then one short paragraph.
3. Key takeaways: 3 to 5 bullets, each a concrete idea from the episode, not a topic name.
4. Chapters: 4 to 10 for a 20 to 60 minute episode, first at 00:00, titles under 40 characters, in the order they happen.
5. Quotes: 3 to 5 lines that make sense without context, with speaker and time. Remove filler words only; never change meaning. Mark edited quotes so the user can check them against the audio.
6. Guest bio (2 or 3 sentences), links and resources mentioned (only real ones from the material or the user), credits, sponsor disclosure if there was an ad.
7. Social posts: one per platform the user names, each with one quote or takeaway.

### 4. Deliver
Fill in `templates/show-notes.md` and follow `references/show-notes-structure.md` and `references/chapters-and-platforms.md`. Follow the style of `examples/example-rooftop-beekeeping-episode.md`. Add a short "check before publishing" list: estimated times, edited quotes, spellings, and any facts or numbers the guest stated that should be verified.

## Rules
- Only use facts, names, numbers, and links from the transcript or the user; flag anything unclear as [check].
- Quotes must be the speaker's own words; removing "um" and "you know" is fine, rewording is not.
- Keep chapter titles descriptive and honest; no clickbait the episode does not deliver.
- Respect guests: do not quote private remarks, off-the-record moments, or anything the user marks as cut.
- Match the show's voice; default to warm, clear, and specific.

# Show notes structure

Listeners skim show notes in a podcast app on a phone, search engines read them on the episode page, and the guest shares them. Each section has one job.

| Section | Job | Length |
|---|---|---|
| Episode title | Say the main promise; help search | 40 to 60 characters; most apps cut after about 60 |
| Preview summary | Make someone press play from the app list | First 150 characters must work alone; 2 sentences total |
| Full summary | Explain who the guest is and what you cover | 60 to 120 words |
| Key takeaways | Give skimmers the value | 3 to 5 bullets, one idea each, under 20 words |
| Chapters | Let listeners jump | 4 to 10 for 20 to 60 minutes; titles under 40 characters |
| Pull quotes | Quotable lines for notes and social | 3 to 5, 12 to 30 words each, with speaker and time |
| Guest bio | Credit the guest | 2 or 3 sentences, written in third person |
| Links and resources | Everything mentioned that has a link | Only links the user or guest gave |
| Credits and disclosure | Host, guest, producer, music, sponsor | One line each |
| Call to action | One next step | Subscribe, review, newsletter, or a question for listeners |

## Titles

- Lead with the idea, not the episode number: "Keeping Bees on a Hotel Roof with Daniel Okafor" beats "Ep. 48: Daniel Okafor".
- Use the words a listener would search: "rooftop beekeeping", "city honey".
- Avoid questions the episode does not answer and promises the guest did not make.

## Summaries

- Sentence 1: who and what, in plain words. Sentence 2: the most surprising or useful point.
- Write for people, not keywords; include the 2 or 3 search phrases naturally once each.
- No "In this episode we talk about..." filler; start with the substance.

## Key takeaways

Write each takeaway as a claim or instruction from the episode, not a topic:
- Weak: "Water on roofs."
- Strong: "Give rooftop bees a shallow water tray, or they will find the neighbors' pool."

## Chapter titles

- Describe what the listener gets in that part, in 2 to 6 words: "Why wind is the real enemy".
- Keep them parallel in style (all statements or all questions).
- Name ad breaks only if the platform does not hide them; never call an ad a chapter about content.

## Quotes

- Pick lines that stand alone: a clear claim, a lesson, a number, or a vivid image.
- Avoid greetings, setup questions, and lines that need the previous sentence.
- Removing fillers (um, uh, you know) is fine; mark the quote as lightly edited. Changing words is not.

## Accessibility and trust

- Link a full transcript when one exists; it helps deaf and hard-of-hearing listeners and search.
- Disclose sponsors and affiliate links clearly.
- Put a [check] tag on any number, name, or claim that should be verified before publishing.
FILE:references/chapters-and-platforms.md
# Chapters and platform rules

Rules change; when in doubt, check the platform's current help page. These are the stable basics.

## YouTube (video podcasts and audio uploads)

- Chapters come from timestamps in the description, one per line: `00:00 Intro`.
- The first timestamp must be 00:00.
- At least 3 timestamps, and each chapter at least 10 seconds long.
- Use `MM:SS` for videos under an hour and `H:MM:SS` once any chapter is past one hour.
- `chapterize.py --format youtube` prints lines in this format and warns when a rule is broken.

## Spotify

- Spotify reads chapter timestamps from the episode description in the same `MM:SS Title` style for episodes on its platform; follow the same rules as YouTube (start at 00:00, a few minutes apart).

## Apple Podcasts and most other apps

- Chapters are embedded in the audio file: ID3 CHAP frames in MP3 or a chapter track in M4A/AAC. Add them in the audio editor or a tagging tool before uploading.
- Apple may show automatically generated chapters when an episode has none; providing your own keeps control of the titles.

## Podcasting 2.0 (RSS)

- The `<podcast:chapters>` tag points to a JSON chapters file, supported by many modern apps and hosts:
```json
{
  "version": "1.2.0",
  "chapters": [
    { "startTime": 0, "title": "Intro" },
    { "startTime": 280, "title": "Keeping bees on a windy roof" }
  ]
}
```
- `startTime` is in seconds; `chapterize.py --format json` gives `start` in seconds for each chapter.

## Timestamps

- Transcript times often differ from the final file: intros, ads, and edits shift them. Use `--offset` for a fixed shift and recheck a few chapters in the audio.
- Without timestamps, `chapterize.py` estimates times from word count (default 150 words per minute) and marks them with `~`. Never publish estimated times without checking.
- Dynamic ad insertion moves times per listener; put chapters in the file or description only when ads are baked in or the host adjusts chapters automatically.

## How the script finds chapter starts

1. Headings (`# Title`, `Chapter 3: ...`, `Segment: ...`) always start a chapter.
2. Pause markers (`[music]`, `[ad break]`, `[pause]`, `***`, `---`) mark the next spoken block as a candidate.
3. Section cue phrases score high ("let's talk about", "moving on", "switching gears", "welcome back", "before we wrap up"); single-question cues ("next question") score lower so a Q&A segment stays one chapter.
4. Vocabulary shift: how different the words are in the 3 blocks before and after a point.
5. Starts closer than `--min-chapter` minutes are dropped (headings excepted), and nothing starts in the last minute.

## Quote and transcript ethics

- Keep quotes faithful; mark filler removal as an edit.
- Ask before quoting a guest's personal story on social media if it was sensitive.
- Do not publish remarks the user marked as off the record or cut from the episode.

Review of the candidates: all six starts land on real transitions ("Let's talk about the roof itself", "Switching gears to the hotel manager", "Welcome back", "Let's move on to listener questions", "Before we wrap up"). The 13:30 ad break stays inside chapter 3 because the ad is baked in. Chapter 1 is long, so it was split by hand at 01:20 ("What was the biggest mistake?"), which becomes 02:05 after the offset. Every keyword title was rewritten.

# Keeping Bees on a Hotel Roof with Daniel Okafor

**Small Plot Radio** | Episode 48 | 26:02 | Guest: Daniel Okafor

Daniel Okafor keeps twelve beehives on a downtown hotel roof. He explains how to beat wind, heat, and thirst on a roof, and why planting flowers can help pollinators more than adding hives.

Nine years ago a swarm landed on Daniel's balcony; today he runs twelve hives on a hotel roof, supplies the hotel kitchen with honey, and leads sold-out rooftop honey tours. Maya and Daniel talk about beginner mistakes, windbreaks, water trays, and roof loads, how he won over a hotel manager, whether city honey is safe to eat, and why too many city hives can crowd out wild bees. They finish with listener questions on balcony beekeeping, starter equipment, and honey yields.

## Key takeaways

- Inspect hives every 7 to 10 days in spring, with a plan, and leave them alone in between.
- On a roof, wind is the main enemy: a 1.5 m slatted windbreak on the exposed sides makes the difference.
- Give rooftop bees a shallow water tray with pebbles, or they will find the neighbors' pool.
- Have the roof load checked first: a full hive can weigh 80 to 100 kg.
- Planting flowers helps pollinators more than adding another hive to a crowded city.

# robots.txt 与 Sitemap 检查器

你是「robots.txt 与 Sitemap 检查器」技能助手。上方 description 为中文任务说明。下方保留原技能完整正文（含脚本与代码）；执行时遵循中文说明与原文技术细节。

# Robots.txt and Sitemap Checker

You help site owners, SEO specialists and web developers make sure search engines can crawl the pages that matter and skip the ones that do not. From a robots.txt, an XML sitemap and a list of important URLs, you show which rule decides each URL, find contradictions between robots.txt and the sitemap, explain each problem in plain words and propose a corrected robots.txt and sitemap fixes.

## Files in this skill

- `scripts/crawl_check.py` - parses robots.txt and a sitemap, decides allowed or blocked per URL like Googlebot, and prints a URL table and findings (Python 3 standard library only, no network)
- `references/robots-txt-rules.md` - groups, longest-match and wildcard rules with examples, supported directives, common mistakes and how to test
- `references/sitemap-rules-and-fixes.md` - sitemap format and limits, what to list, lastmod, and the fix for each finding
- `templates/crawl-audit-report.md` - an audit report with a proposed robots.txt to hand to the developer
- `examples/outdoor-shop-crawl-check.json` - an outdoor gear shop after a relaunch: blog and JS blocked by mistake, a noindex line, an open admin path, and a sitemap with a blocked, an off-site, a duplicate and badly dated URLs

## Workflow

### 1. Collect the files
Ask for the live robots.txt (`https://<host>/robots.txt`), the sitemap or sitemap index, the canonical origin (scheme and host), and two short lists: URLs that must be crawlable (home, categories, top products or articles, CSS/JS bundles) and URLs that should be blocked (cart, checkout, internal search, filters, admin). Ask which crawler matters most (default Googlebot).

### 2. Run the checker
```
python3 scripts/crawl_check.py examples/outdoor-shop-crawl-check.json --today 2026-10-23
python3 scripts/crawl_check.py --robots robots.txt --sitemap sitemap.xml --site https://www.example.com --allow /product/x --block /cart/
python3 scripts/crawl_check.py --self-test
```
A bundle JSON holds the site, crawler, robots.txt and sitemap lines and the URL lists. Exit code 1 means CRITICAL or HIGH findings, 2 means bad input.

### 3. Explain and fix
Start with CRITICAL and HIGH: whole-site blocks, important pages blocked, sitemap URLs that robots.txt blocks, off-site sitemap entries. For each, name the deciding line and give the corrected rule. Explain that robots.txt does not remove pages from search or protect private pages (`references/robots-txt-rules.md`), and point to the fix table in `references/sitemap-rules-and-fixes.md`.

### 4. Deliver
Fill `templates/crawl-audit-report.md` with the URL table, findings, a full corrected robots.txt and the sitemap generator changes, then re-run the checker on the corrected files.

## Example result
For `examples/outdoor-shop-crawl-check.json` the status is HIGH: `Disallow: /blog/` (line 9) blocks /blog/trail-running-shoes-review and the listed /blog/spring-sale-recap, `Disallow: /assets/js/` blocks the app bundle, and http://trailgear.example/backpacks/ in the sitemap is off-site. The `Noindex: /search/` line is ignored by Google, so /search/ and /admin/ stay crawlable; the sitemap also has a duplicate /tents/, a lastmod in 2027 and one in `18.10.2026` format.

## Rules

- Always name the exact robots.txt line that decides a URL, and the crawler it was evaluated for.
- Never suggest robots.txt to hide private or sensitive pages; use authentication, and `noindex` for pages that must stay out of search.
- Give a complete corrected robots.txt, not only fragments, and keep rules the owner added on purpose (for example blocking AhrefsBot).
- The checker does not fetch URLs; say that status codes, redirects, canonicals and noindex tags need a crawl or Search Console.
FILE:references/robots-txt-rules.md
# robots.txt Rules (RFC 9309 and Google)

## Where and what
- Lives at the root of each host and protocol: `https://www.example.com/robots.txt` covers only that host. `example.com`, `shop.example.com` and `http://` need their own file.
- Plain text, UTF-8. Google reads the first 500 KiB. A 404 means "everything allowed"; a 5xx for a long time can make Google stop crawling the site.
- robots.txt controls **crawling**, not indexing. A blocked URL can still appear in search (without a snippet) if other pages link to it. To keep a page out of search, allow crawling and send `noindex`; to keep it private, require a login.

## Groups
```
User-agent: Googlebot
User-agent: Bingbot
Disallow: /tmp/

User-agent: *
Disallow: /cart/
```
- Consecutive `User-agent` lines share one group. Rules belong to the group above them.
- A crawler uses only **one** group: the one with the most specific matching name (`googlebot-image` over `googlebot`), otherwise `*`. Rules from `*` are not added to a named group, so a common mistake is a `Googlebot` group that forgets to repeat the `*` rules.
- Groups with the same name are merged.

## Matching
- Paths are case-sensitive and match from the start of the path (including the query string).
- `*` matches any characters; `$` anchors the end of the URL.
- The **longest** matching rule wins; on equal length `Allow` wins. No matching rule means allowed.
- `Disallow:` with an empty value allows everything.

| Rule | Blocks | Does not block |
|---|---|---|
| `Disallow: /shop` | /shop, /shop/, /shopping | /Shop |
| `Disallow: /shop/` | /shop/shoes | /shop |
| `Disallow: /*?sort=` | /tents/?sort=price | /tents/?color=red&sort=price (needs `/*sort=`) |
| `Disallow: /*.pdf$` | /docs/a.pdf | /docs/a.pdf?v=2 |
| `Disallow: /blog/` + `Allow: /blog/guides/` | /blog/news | /blog/guides/x |

## Directives
| Directive | Google | Notes |
|---|---|---|
| user-agent, allow, disallow | yes | core rules |
| sitemap | yes | absolute URL, any number, outside groups |
| crawl-delay | no | Bing and Yandex honour it; for Google, lower the crawl rate via server responses (429/503) |
| noindex, nofollow | no (dropped 2019) | use `<meta name="robots" content="noindex">` or the `X-Robots-Tag` header |
| host, clean-param | no | Yandex only |

## Common mistakes
- `Disallow: /` left over from staging after a launch (the whole site disappears from crawling).
- Blocking CSS, JS or image folders: Google renders pages and needs them; blocked assets can make pages look broken or not mobile-friendly.
- Blocking a page that carries `noindex`: the crawler never sees the noindex, so the URL can stay in the index.
- Using robots.txt to hide admin or private pages: the file is public and lists exactly where they are.
- Faceted URLs (sort, filter, session ids) left open, wasting crawl budget on endless combinations.
- Typos (`Disalow`) are silently ignored.

## Testing
- Google Search Console: robots.txt report (fetch status and parsed rules) and URL Inspection (blocked or not).
- Locally: `python3 scripts/crawl_check.py --robots robots.txt --site https://www.example.com --allow /product/x --block /cart/`.

# XML Sitemap Rules and Fixes

## Format
```xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://www.example.com/tents/ultralight-2p</loc>
    <lastmod>2026-10-18T09:30:00+03:00</lastmod>
  </url>
</urlset>
```
- At most **50,000 URLs** and **50 MB** uncompressed per file. Larger sites use a sitemap index (`<sitemapindex>` with `<sitemap><loc>` entries), up to 50,000 sitemaps.
- UTF-8, entity-escape `&`, `<`, `>`, `'`, `"` inside `<loc>`.
- `<loc>` must be absolute, on the same protocol and host as the sitemap (unless cross-submitted through Search Console for a verified host).

## What to list
- Only canonical, indexable URLs that return 200: no redirects, no 404s, no `noindex` pages, no URLs blocked by robots.txt, no parameter duplicates.
- The exact canonical form: same scheme (https), same host (www or not), same trailing-slash style as the `rel=canonical` tag.
- Each URL once.

## lastmod
- W3C datetime: `2026-10-18`, `2026-10-18T09:30+03:00` or `2026-10-18T06:30:00Z`. Formats like `18.10.2026` or `10/18/2026` are invalid.
- Set it to the last **meaningful** content change, not the build time. Google uses lastmod only when it is consistently accurate; future dates or every URL changing every day teach it to ignore the field.
- `<changefreq>` and `<priority>` are ignored by Google; they do no harm but are not worth maintaining.

## Telling crawlers about the sitemap
- `Sitemap: https://www.example.com/sitemap.xml` in robots.txt (absolute URL).
- Submit in Google Search Console and Bing Webmaster Tools, then watch the "Discovered" and "Indexed" counts and errors.

## Fixes by finding
| Finding | Fix |
|---|---|
| SITEMAP_URL_BLOCKED | Decide: if the page should rank, remove the Disallow; if not, drop it from the sitemap |
| SITEMAP_OFF_SITE | Rewrite `<loc>` to the canonical scheme and host; check the generator's base URL setting |
| SITEMAP_DUPLICATE | Deduplicate in the generator (often category + tag listings of the same page) |
| LASTMOD_INVALID / LASTMOD_FUTURE | Output ISO 8601 from the content's updated-at field; check server time zone and clock |
| SITEMAP_TOO_BIG | Split by section or date into several files under one sitemap index |
| SITEMAP_PARSE_ERROR | Escape `&` in URLs, remove a BOM or HTML error pages served instead of XML, check the namespace |

## Beyond this checker
The script works offline on the files you give it. Also check, with a crawler or Search Console: status codes of listed URLs, redirects, canonical tags, noindex tags and hreflang alternates.

# Crawl Audit - <site> - <date>

**Checked:** robots.txt (<fetched on / version>), <sitemap URL(s)>  **Crawler:** <Googlebot>  **Reviewer:** <name>

## Summary
- Status: <CRITICAL / HIGH / OK>
- robots.txt: <n> groups, <n> rules for <crawler>
- Sitemap: <n> URLs, <n> blocked, <n> off-site, <n> duplicates

## Important URLs
| URL | Should be | Result | Deciding rule | Fix |
|---|---|---|---|---|
| | crawlable | | | |
| | blocked | | | |

## Proposed robots.txt
```
User-agent: *
Disallow: ...
Allow: ...

Sitemap: https://...
```

## Follow-up
- Deploy the new robots.txt and sitemap on <date>; test in Search Console (robots.txt report, URL Inspection)
- Recheck coverage and crawl stats on <date>

"""robots.txt and XML sitemap checker (Python 3 standard library only, works offline).

Input, either:
  a JSON bundle  {"site": "https://www.example.com", "user_agent": "Googlebot",
                  "robots_txt": [lines] or "text", "sitemap_xml": [lines] or "text",

  or files       --robots robots.txt [--sitemap sitemap.xml] --site https://... [--allow URL] [--block URL]
Matching follows RFC 9309 / Google: the group whose user-agent token matches the crawler name
(case-insensitive, most specific wins, else "*"), then the longest matching Allow/Disallow path
(* = any characters, $ = end of URL); on a tie Allow wins; no match = allowed.
Findings (severity):
  CRITICAL BLOCK_ALL               "Disallow: /" applies to the crawler with no Allow rules
  HIGH     MUST_CRAWL_BLOCKED      a URL that must be crawlable is disallowed
  HIGH     SITEMAP_URL_BLOCKED     a URL listed in the sitemap is disallowed
  HIGH     SITEMAP_PARSE_ERROR     sitemap is not well-formed XML or not urlset/sitemapindex
  HIGH     SITEMAP_TOO_BIG         more than 50,000 URLs in one sitemap
  HIGH     SITEMAP_OFF_SITE        a sitemap URL is on another host or scheme than the site
  MEDIUM   MUST_BLOCK_CRAWLABLE    a URL that should be blocked is crawlable (robots.txt is not access control)
  MEDIUM   ASSETS_BLOCKED          CSS, JS or image paths disallowed (pages cannot render for the crawler)
  MEDIUM   UNSUPPORTED_RULE        noindex / nofollow / host lines (ignored by Google)
  MEDIUM   SITEMAP_DUPLICATE       the same <loc> appears more than once
  MEDIUM   LASTMOD_FUTURE          <lastmod> after --today
  LOW      CRAWL_DELAY_IGNORED     crawl-delay (Googlebot ignores it; Bing and Yandex honour it)
  LOW      RULE_OUTSIDE_GROUP      allow/disallow before any user-agent line
  LOW      UNKNOWN_DIRECTIVE       unknown line or missing colon
  LOW      SITEMAP_RELATIVE        Sitemap: line is not an absolute URL
  LOW      NO_SITEMAP_LINE         robots.txt has no Sitemap: line
  LOW      LASTMOD_INVALID         <lastmod> is not W3C datetime (YYYY-MM-DD[Thh:mm[:ss]TZD])

# Open Graph and Social Share Meta Tag Checker

You make shared links look right on Facebook, LinkedIn, X, Slack, Discord, WhatsApp and iMessage. You read the page source the crawlers see, show the user what the preview will be built from (title, description, image, domain), explain why a preview is blank, cropped or showing the logo, and hand back a corrected `<head>` block. You work from saved HTML; you never claim you fetched the live page or saw a platform's cache.

## Files in this skill

- `scripts/og_meta_check.py` - parses HTML with `html.parser` and checks title, description, canonical, og:* and twitter:* tags; with `--root` it reads the real width/height and file size of local PNG/JPEG/GIF/WebP share images (Python 3.8+ standard library only)
- `references/tag-rules.md` - each tag, the values crawlers accept, lengths, image sizes and fallbacks
- `references/platform-notes.md` - how Facebook, LinkedIn, X, Slack, Discord, WhatsApp and iMessage build previews, cache them and how to refresh
- `templates/share-meta-review.md` - the review to hand back (preview, fix table, fixed head block, refresh steps)
- `examples/product-page.html` - a product page whose theme and SEO plugin both write tags, with mistakes on purpose
- `examples/product-page-fixed.html` - the same page with a correct head (checks clean)
- `examples/meta-report.md` - the real output of the checker on the broken example

## Workflow

### 1. Get the HTML the crawlers see
Ask for the page URL and the server-rendered source, not the DevTools Elements view (that shows tags added by JavaScript, which most crawlers never run):
```
curl -sL -A "facebookexternalhit/1.1" https://example.com/page -o page.html
curl -sL -A "Twitterbot/1.0" https://example.com/page -o page-x.html
```
For a static site or a build folder, point the checker at the folder and pass `--root` so share images are measured from disk. Ask which platforms matter most (B2B: LinkedIn and Slack; consumer: WhatsApp, iMessage, Facebook, X).

### 2. Run the checker
```
python3 scripts/og_meta_check.py examples/product-page.html --url https://shop.example.com/shoes/trail-grip
python3 scripts/og_meta_check.py dist/ --root dist/ --min-severity MEDIUM
python3 scripts/og_meta_check.py page.html --url https://example.com/blog/post --json
python3 scripts/og_meta_check.py --self-test
```
Give `--url` for a single page so relative links are resolved and canonical/og:url compared. Exit 0 = no HIGH, 1 = HIGH findings, 2 = bad input. If you cannot run code, walk through `references/tag-rules.md` in the same order.

### 3. Explain the preview
- Start with the preview table: that is what people will see. A missing, relative or SVG `og:image` is the usual reason for a bare text link; a square or small image gets a small thumbnail instead of a large card.
- **HIGH** breaks the preview (no or relative og:image, image under 200x200, no title, several canonicals). **MEDIUM** shows the wrong thing (duplicates, placeholders, tags in `<body>`, invalid twitter:card, tracking parameters, SVG). **LOW** is polish (lengths, alt text, locale format, site_name).
- Duplicates usually come from two systems (theme plus SEO plugin, framework default plus page component). Say which one to switch off rather than adding a third set.

### 4. Deliver
Fill `templates/share-meta-review.md`: the before/after preview, the fix table, one complete `<head>` block with real values (or clearly marked placeholders), the share image spec (1200x630 JPEG/PNG under ~1 MB, text in the safe centre), and how to refresh caches (Facebook Sharing Debugger "Scrape Again", LinkedIn Post Inspector; X, Slack and WhatsApp re-fetch after their cache expires or with a changed URL).

## Example result
On `examples/product-page.html` the checker reports 21 findings (HIGH 1, MEDIUM 10, LOW 10): the only og:image in `<head>` is a relative SVG logo, the real product image sits in `<body>` at 800x800, the SEO plugin adds a second og:title with an unrendered `{{ product.name }}`, og:url carries `?utm_source=newsletter` and differs from the relative canonical, `twitter:card` is `large`, twitter:site is a URL instead of `@peakline`, og:description uses `name=` and runs 269 characters, and the title is just `Peakline`. `examples/product-page-fixed.html` checks clean (exit 0).

## Rules

- Judge the server-rendered HTML; say plainly when tags exist only after JavaScript runs.
- Never invent product facts, prices or brand handles for the fixed tags; use the page's own copy or mark `<placeholder>`.
- One value per single-value tag; remove the duplicate source instead of overriding it.
- All URLs in og:url, og:image, twitter:image and canonical must be absolute https:// URLs without tracking parameters.
- Do not promise how a platform will crop or when it refreshes; give the documented sizes and the refresh tool, and mark the rest "to verify" in the platform's debugger.
- Keep og:title free of the site-name suffix (og:site_name carries the brand) unless the user wants it.
FILE:references/tag-rules.md
# Tag rules

Review order: title and description -> canonical -> og core tags -> og:image -> twitter:* -> placement, duplicates and placeholders.

## Basic head tags
| Tag | Rule | Checker range |
|---|---|---|
| `<meta charset="utf-8">` | first in `<head>`, so non-ASCII text in previews is decoded | LOW if missing |
| `<title>` | one per page, specific, brand at the end | 15-60 characters (LOW outside) |
| `<meta name="description">` | one, plain sentence(s), no keyword lists | 50-160 characters (LOW outside) |
| `<link rel="canonical">` | one, absolute https URL, no tracking parameters, in `<head>` | MEDIUM missing/relative, HIGH several |

## Open Graph (ogp.me)
- Use `property="og:..."` and `content="..."`. `name="og:..."` works on some platforms only; `value=` or text content is ignored.
- `og:title` - the headline without the site suffix, up to ~70 characters shown fully (checker warns over 90).
- `og:description` - 1-2 sentences, ~200 characters max shown.
- `og:type` - `website` for home and landing pages, `article` for posts (add `article:published_time`), `product` for shop pages.
- `og:url` - the canonical URL, so likes and shares of `?utm=` variants merge into one object.
- `og:site_name` - the brand; LinkedIn and Slack show it above the title.
- `og:locale` - `language_TERRITORY` with an underscore: `en_US`, `de_DE`, `pt_BR`; alternates with `og:locale:alternate`.
- Single-value tags (`og:title`, `og:description`, `og:type`, `og:url`, `og:site_name`, `og:locale`) must appear once. `og:image` may repeat (several images); the first is usually used.

## og:image
- Absolute https URL that returns 200 to crawlers without login, cookies or hotlink protection, `Content-Type: image/jpeg|png|webp|gif`.
- Size: at least 200x200 (Facebook minimum, HIGH below), 1200x630 recommended for large cards (MEDIUM below), 1.91:1 aspect for `summary_large_image` (LOW if outside 1.75-2.05). `summary` cards use a square crop.
- File size: under ~1 MB loads reliably; X rejects images over 5 MB, Facebook over 8 MB.
- SVG is not rendered by the major platforms (MEDIUM). Animated GIFs show the first frame.
- Add `og:image:width` and `og:image:height` (whole numbers, pixels) so Facebook renders the first share before it has downloaded the image; with `--root` the checker compares them with the file.
- `og:image:alt` - a sentence describing the image (used by X and LinkedIn for screen readers).
- Change the image URL (e.g. `share-v2.jpg`) when you replace an image; platforms cache by URL.

## X (Twitter) cards
- `twitter:card`: `summary`, `summary_large_image`, `app` or `player`. Anything else is invalid; without the tag X falls back to a small summary card.
- X reads `og:title`, `og:description` and `og:image` when `twitter:title/description/image` are absent, so only add those to show different text on X.
- `twitter:site` (the brand) and `twitter:creator` (the author) are `@handles`, not URLs.

## Placement, duplicates, placeholders
- Crawlers read `<head>` only. A `<div>`, `<img>` or text before `</head>` ends the head implicitly in HTML parsing, so tags after it count as body tags.
- Theme + SEO plugin (WordPress, Shopify), framework default + page component (Next.js `metadata`, Nuxt `useHead`) are the usual sources of duplicates. Keep one source.
- Unrendered template text (`{{ product.name }}`, `title`, `<%= %>`), `undefined`, `null`, `[object Object]`, `NaN`, `TODO` and lorem ipsum mean the server rendered the tag before the data was ready, or a client-only component wrote it.
- Tracking parameters (`utm_*`, `fbclid`, `gclid`, `ref`, `mc_cid`) never belong in canonical or og:url.

## Fixed head block (shape)
```
<meta charset="utf-8">
<title>{Page headline} | {Brand}</title>
<meta name="description" content="{50-160 characters}">
<link rel="canonical" href="https://{host}/{clean-path}">

# Platform notes

What each app reads, how long it caches, and how to refresh. Behaviour changes over time: confirm in the platform's own debugger before promising a result.

| Platform | Crawler user agent | Reads | Image used | Cache / refresh |
|---|---|---|---|---|
| Facebook, Messenger | `facebookexternalhit/1.1` | og:*, then title/description | og:image, 1200x630 large card, 200x200 minimum | ~30 days; Sharing Debugger -> "Scrape Again" |
| Instagram (link stickers, DMs) | Facebook crawler | og:* | og:image | as Facebook |
| LinkedIn | `LinkedInBot/1.0` | og:* (title, description, image, site_name) | og:image, 1200x627, min 200 px wide | ~7 days; Post Inspector re-scrapes |
| X | `Twitterbot/1.0` | twitter:*, falls back to og:* | twitter:image or og:image; large card needs `summary_large_image` | ~7 days; no public refresh tool, change the URL (add `?v=2` to the shared link, not to canonical) |
| Slack | `Slackbot-LinkExpanding 1.0` | og:*, twitter:*, oEmbed | og:image (large when 1.91:1) | ~30 min per workspace; re-post after the fix |
| Discord | `Discordbot/2.0` | og:*, twitter:card, `theme-color` for the side bar | large image with `summary_large_image` | cached; append a query string to re-test |
| WhatsApp | `WhatsApp/2.x` | og:title, og:description, og:image | og:image; small files (a few hundred KB) give the most reliable thumbnails | per device; new link or new image URL |
| iMessage | Apple's link preview fetcher (runs on the sender's device) | og:title, og:image, favicon | og:image or apple-touch-icon | on device |
| Telegram | `TelegramBot` | og:* | og:image | @WebpageBot to refresh |

## Common reasons a preview is wrong
- **No preview at all:** crawler blocked by robots.txt, login wall, bot protection/WAF challenge, geo-block, or the page returns 403/5xx to unknown user agents. Test with `curl -sI -A "facebookexternalhit/1.1" URL`.
- **Old title or image:** the platform cache. Fix the tags, then refresh with the tools above; replace the image under a new filename.
- **Logo instead of the product image:** og:image points at the logo, or the right tag sits in `<body>` and is ignored.
- **Cropped text on the image:** keep important text inside the centre ~80% of a 1200x630 canvas; LinkedIn and X crop the edges differently.
- **Wrong language or mojibake:** missing `<meta charset="utf-8">` or the server sends a different `Content-Type` charset.
- **Single-page apps:** tags set by client-side JavaScript are not seen by Facebook, LinkedIn, Slack or WhatsApp. Pre-render or render the head on the server.

## Testing checklist
1. `curl` the page with each crawler user agent and run the checker on the saved files.
2. `curl -sI` the og:image URL: 200, an image Content-Type, size under 1 MB, no redirect to a login page.
3. Paste the URL into Facebook Sharing Debugger and LinkedIn Post Inspector; post it in a private Slack/Discord channel.
4. Record the before/after screenshots in the review.
FILE:templates/share-meta-review.md
# Share preview review: <page URL>

**Source:** <curl -A facebookexternalhit, saved <date>>   **Platforms that matter:** <LinkedIn, Slack, WhatsApp>
**Result:** <HIGH n, MEDIUM n, LOW n> - <one-sentence verdict, e.g. "shares show the logo and a template placeholder; fix the SEO plugin output">

## Preview now vs after the fix
| Field | Now | After |
|---|---|---|
| Title | <{{ product.name }} / Peakline> | <Trail Grip - the trail shoe for wet rock> |
| Description | <269 characters, cut mid-sentence> | <Grippy, light trail shoes tested on wet granite and mud. ...> |
| Image | </img/logo.svg (relative SVG)> | <https://shop.example.com/img/trail-grip-share-1200x630.jpg> |
| Card on X | <invalid "large"> | <summary_large_image> |

## Fix list
| # | Sev | Tag | Problem | Fix | Where |
|---|---|---|---|---|---|
| 1 | <HIGH> | <og:image> | <relative SVG logo> | <absolute 1200x630 JPEG> | <theme header.liquid> |
| 2 | <MEDIUM> | <og:title> | <duplicate from SEO plugin, unrendered> | <disable theme OG output, keep plugin> | <plugin settings> |

## Fixed head block
```
<paste the complete corrected tags here, in this order: charset, title, description, canonical, og:*, twitter:*>
```

## Share image spec
- <1200x630 JPEG or PNG, under ~1 MB, new filename; text and logo inside the centre 80%>
- <alt text: "...">

## After deploying
1. <curl -sL -A "facebookexternalhit/1.1" <URL> | grep -E 'og:|twitter:|canonical'>
2. <Facebook Sharing Debugger: Scrape Again; LinkedIn Post Inspector: Inspect>
3. <post in a private Slack channel; check X with a fresh share>

**To verify (not checked offline):** <image URL returns 200 to crawlers; robots.txt/WAF does not block the user agents; tags present without JavaScript>
**Open questions:** <which system should own the tags - theme or SEO plugin? per-product share images available?>

| MEDIUM | TWITTER_CARD_INVALID | twitter:card | 18 | twitter:card 'large' is not one of summary, summary_large_image, app, player | use summary_large_image (or summary) |
| MEDIUM | TAG_OUTSIDE_HEAD | og:image | 26 | og:image is inside `<body>`; Facebook and LinkedIn read only `<head>` | move into `<head>` |

| LOW | CANONICAL_OG_URL_MISMATCH | og:url | 12 | og:url (https://shop.example.com/shoes/trail-grip?utm_source=newsletter) differs from canonical (/shoes/trail-grip) | use the canonical URL in og:url |

| LOW | OG_USES_NAME_ATTR | og:description | 17 | og:description uses name= instead of property= (Open Graph spec; some parsers skip it) | `<meta property="og:description" ...>` |
| LOW | TWITTER_HANDLE_FORMAT | twitter:site | 19 | twitter:site 'https://x.com/peakline' should be an @handle | e.g. @brand |

Offline check of the saved HTML only: tags injected by JavaScript after load are invisible to most crawlers too, but redirects, robots rules, the live image URL and each platform's preview cache were not tested.
FILE:scripts/og_meta_check.py
#!/usr/bin/env python3
"""Open Graph and social share meta tag checker (Python 3.8+ standard library only).

Reads saved HTML (a file, several files, or a folder of *.html) and checks what link
previews on Facebook, LinkedIn, X, Slack, Discord, WhatsApp and iMessage will be built from:
<title>, meta description, rel=canonical, og:* (title, description, type, url, image,
image:width/height/alt/type, site_name, locale) and twitter:* card tags.

It flags missing and duplicate tags, relative or http:// URLs, canonical vs og:url
mismatches, title/description length, image size hints (declared or, with --root, read
from local PNG/JPEG/GIF/WebP files), SVG images, wrong attributes (name= vs property=),
tags outside <head>, and template placeholders ({{ }}, TODO, undefined).

Usage:
  python3 og_meta_check.py page.html [more.html | folder/] [--url https://example.com/page]
                           [--root public/] [--min-severity LOW|MEDIUM|HIGH] [--ignore CODE,..] [--json]
  python3 og_meta_check.py --self-test

--url   the page's public URL (used to resolve relative links and compare canonical/og:url)
--root  local folder that maps to the site root, so /img/share.png is read from root/img/share.png

Exit codes: 0 = no HIGH findings, 1 = HIGH findings, 2 = bad input. No network calls are made.

# Astro Content Site taste of a performance-minded web developer
- Use Astro for content-heavy sites like docs, blogs and marketing pages, and pick a full app framework only when most pages are interactive. Confidence: 0.85
- Ship zero JavaScript by default and add islands only for the components that truly need interactivity. Confidence: 0.90
- Choose the lightest client directive that works, preferring client:visible or client:idle over client:load. Confidence: 0.85
- Define content collections with a schema so every Markdown or MDX file is validated and typed at build time. Confidence: 0.90
- Keep content in the repo as Markdown or MDX until editors really need a headless CMS. Confidence: 0.75
- Build pages statically by default, and switch individual routes to server rendering only when they need fresh or per-user data. Confidence: 0.85
- Use the built-in Image component with explicit widths and modern formats instead of plain img tags for local images. Confidence: 0.90
- Self-host fonts, subset them, and preload only the one or two files used above the fold. Confidence: 0.80
- Style with scoped component styles or a utility framework, and keep global CSS limited to tokens and resets. Confidence: 0.75
- Write layouts as nested components that set titles, meta descriptions, canonical URLs and Open Graph tags from props. Confidence: 0.90
- Generate a sitemap and RSS feed from the content collections instead of maintaining them by hand. Confidence: 0.85
- Keep URLs stable and add redirects in config whenever a slug changes, so old links never return 404. Confidence: 0.90
- Use semantic HTML with one h1 per page, real headings in order, and alt text required by the content schema for images. Confidence: 0.90
- Use View Transitions sparingly for page navigation and respect prefers-reduced-motion. Confidence: 0.70
- Load third-party scripts like analytics and chat widgets late, or move them off the main thread with Partytown. Confidence: 0.75
- Keep framework islands in one UI library per site rather than mixing React, Vue and Svelte without a reason. Confidence: 0.80
- Run astro check and TypeScript in strict mode in CI so broken frontmatter and props fail the build. Confidence: 0.85
- Check every pull request with link checking and Lighthouse budgets for performance, accessibility and SEO. Confidence: 0.80
- Deploy previews for each pull request so writers and reviewers can read changes before they merge. Confidence: 0.85
- Add search with a static index like Pagefind before reaching for a hosted search service. Confidence: 0.75
- Read secrets only in server code through typed environment variables, and never expose them with a public prefix. Confidence: 0.95
